    Description: This taxonomic revision includes all Ochnaceae from South and Southeast Asia, Malesia, Australia, and the Pacific Islands. A much wider species concept is applied than in most previous works: 20 species in 10 genera are accepted for the area treated, whereas 199 specific synonyms are listed. A few taxa have been accepted at infra specific level among which Brackenridgea palustris ssp. kjellbergii Kanis is new. It is shown that some old specific names have been overlooked in the past and that the traditional concepts of some species have not been in accordance with the original concepts. All names, currently used for Asiatic species of Ochna L. and Gomphia Schreb. are no longer accepted here, O. jabotapita L. and G. serrata (Gaertn.) Kanis being the correct names for the respective type species. O. fascicularis Blanco is made the type of a distinct section Notochnella (v. Tiegh.) Kanis in the genus Brackenridgea A. Gray. A short history of the taxonomy is given and a partly new suprageneric subdivision of the Ochnaceae is subsequently proposed. Two subfamilies are recognised: the Ochnoideae comprising the tribes Ochneae and Elvasieae Rchb., and the Sauvagesoideae Lindl. including the tribes Sauvagesieae, Euthemideae Planch., and Lophireae Rchb. The Ochneae are newly subdivided in the subtribes Ochninae and Ouratinae (v. Tiegh.) Kanis, and the Sauvagesieae in the subtribes Sauvagesinae and Luxemburginae (Planch.) Kanis.* Some general remarks are made about morphological characters in the family, including some new characters of the pollen. An attempt is made towards a better understanding of the inflorescence types. It is assumed that the genera Ochna and Gomphia migrated from Africa into Asia. Other genera in Southeast Asia, Malesia, Australia, and the Pacific Islands are regarded as long established, because of the more or less relict-like nature of their areas.

    Description: In our revision of Caprifoliaceae in Fl. Mal. I, 4 (1951) 175 seq. we omitted to mention Weigelia fallax described by Miquel from Lembang, West Java, collected by Korthals. The specimen was concealed among cultivated specimens and turned up recently. There is no doubt that this specimen is derived from an ornamental in the Javanese hills. We have sent this material to Prof. Hara who found it conspecific with Weigela coraeensis Thunb. It is often cultivated in Japan, especially as a hedge plant.

    Description: This is a difficult book on account of the very wide range and complexity of its subject-matter, made more difficult by the fact that the author has not taken the trouble to arrange his writing so as to present a clear sequence of ideas; also he often uses needlessly complex sentences, some made more difficult to understand by careless proof-reading. After a first attempt to read the book through, my mind was quite confused; it was only on a second reading, by referring backwards and forwards to different chapters, that I began to have some understanding of its basic ideas. So if in this review I do not do it justice, I feel that the author will be at least in part to blame. Prof. Meeuse has made an attempt to interpret the floral morphology of flowering plants in terms of a new typology. Fie objects to the old typology of carpels and the way in which a great range of different floral structures were interpreted in terms of that typology; but he proceeds to provide a new strait-jacket of his own into which all the same structures must be fitted. He condemns the old morphology as ‘preconceived’, and frequently uses this adjective to discredit the ideas of others. But all his own theoretical ideas must have been conceived in his own mind before he could apply them in detail and give expression to them in the present book; they are therefore also pre-conceived. He should think again what he means by this word.

    Description: Recently, I transferred Ectochaete endophytum to Coelodiscus Jao (van den Hoek, 1965). Dr. R. C. Bakhuizen van den Brink (Rijksherbarium, Leiden), however, drew my attention to the fact that Coelodiscus Jao (1941) is a later homonym of Coelodiscus Baillon (1858). The new generic name Jaosaccion is therefore proposed for the ulotrichalean species so far ranged under Coelodiscus Jao.

    Description: An exhaustive Flora of Delhi, compiled by J. K. Maheshwari, was published by C.S.I.R. in 1963 (for a review see Blumea 13, 1965, p. 174). During the compilation of that flora, 278 line-drawings, illustrating the habits and chief features of the plants found in Delhi, were prepared; they form a welcome addition. In general, the drawings are of a good quality and will be a help to all interested in the determination of Delhi plants.

    Description: In the Flora Malesiana area recent authors have distinguished the following genera in the Lindsaea group of ferns: Isoloma J. Smith, Lindsaea Dryander (often misspelled “Lindsaya”; see Copeland 1947, p. 53, and Kramer 1957a, p. 156), Odontosoria Fee, Protolindsaya Copeland, Schizoloma Gaudichaud (or Schizolegnia Alston), Sphenomeris Maxon, Tapeinidium (Presl) C. Christensen, and Xyropteris Kramer. In my account of the American species (Kramer 1957a) I included the Asiatic genus Schizolepton Fee in the Lindsaea group, on Copeland’s authority, without sufficiently looking into the matter. Holttum (1958) has shown since that its affinities are with Syngramma and has subsequently (1960) combined it with Taenitis, although Pichi-Sermolli (1966) denies any close affinity of the two last-named genera. As stated before (Kramer 1957a, 1967) I am convinced that Schizoloma cannot be maintained as a distinct genus and prefer to treat it as a section of Lindsaea. With regard to Isoloma I have reached the same conclusion, as explained below. Odontosoria sensu stricto does not occur in Asia. Xyropteris is still monotypical, as originally described (Kramer 1957b), and Tapeinidium, including Protolindsaya, as correctly stated by Christensen (1934), forms the subject of a separate paper (Kramer 1968). The notes in the present paper can thus be restricted to Lindsaea and Sphenomeris.

    Description: Although the Indonesian Archipelago is phycologically rather well-known, information about the freshwater algae in New Guinea is very scanty. There are only a few papers, e.g. by Bernard (1910) and Cholnoky (1963), but these give only a glimpse of the phycocoenoses of the New Guinea lakes, especially those of the high mountains. Many of these lakes have been mentioned in travel books, and some seem to be promising localities for freshwater algae. The biogeographical relations between Malesian and Australian regions have been much discussed. A number of biogeographers have attempted to unravel the complex of transition in this part of the world. Phytogeographers often accept the Torres Strait as a boundary between the Malesian and the Australian floras. This is only true in a general statistical way; the flora of the dry savannahs of the southern lowland shows a great similarity to that of northern Australia, while the high-mountain flora shows distinct affinities with both the northern temperate Asiatic flora and the temperate South Pacific flora. Zoogeographers, however, include New Guinea mostly in the Australian region because of the existence of a land-bridge between Australia and New Guinea during past geological epochs (see fig. 11—5, in Knight, 1965). In this connection the character and relations of the freshwater algal flora of New Guinea is of some interest. It has been shown by Scott & Prescott (1958) that the freshwater algal flora of northern Australia is closely related to that of the Indo-Malayan region.

    Description: Joséphine Th. Koster entered her service at the Rijksherbarium as an assistant, April 1930, in the midst of the economic crisis. She was engaged as an, unsalaried collaborator, the then current type of position the Netherlands’ State could offer its scientific offspring. When Prof. Dr. H. J. Lam, freshly appointed Director in August 1933, ordered her to start work each morning as early as the salaried staff-members, she resigned from her unremunerative post by 31 Dec. 1933. She then continued, as a guest of the Rijksherbarium, her investigations on the Compositae of the Dutch East Indies, and in 1935 she took her doctor’s degree on the thesis ‘The Compositae of the Malay Archipelago’ at Leyden University. Her promotor was Prof. Lam. In the end the unfavourable labour-market of that time appeared to have favourable consequences for algology; for Miss Koster, she once confessed to me, had a great ambition to teach biology in secondary schools!

    Description: In the eyes of most aquarists plants have merely a decorative function in the aquarium. Several aquarists, however, have made the plants the subject of their special interest, and it is for these people that Professor De Wit actually wrote his book. In order to make it easier for them he has not followed the usual systematic arrangement of the species but has arranged the species according to their habit. The following growthforms are dealt with successively: 1. Plants freely floating on the surface; 2. Submerged but freely floating plants; 3. Rooting plants with rosettes of filiform, linear, or ribbon-shaped leaves; 4. Plants with leaf-rosettes on the bottom; 5. Rooting plants with floating leaves; 6. Plants with creeping stems and erect leaves; and 7. Plants with erect leaf-bearing stems. There are, however, many species that can be classified in more than one of these vague categories, e.g. Elisma natans, Potamogeton octandrus, many species of Sagittaria and Echinodorus, and all Ceratophyllum species. Two species, Wolffiella floridana and Riccia fluitans, are erroneously classified as plants floating on the surface; they are submerged pleustophytes.

    Description: The term ‘brackish water’ is used in several senses and, therefore, I want at first to explain what I consider to be brackish water and what not. Redeke (1933) defined brackish water as a mixture of fresh water and sea water sensu stricto. This definition excludes the continental salt waters which have a different origin. There exist, however, salt waters which have lost long ago their contact with the sea and have now a chemical composition completely aberrant from sea water, due to the joint effect of continual inflow of new electrolytes with river water, evaporation, and precipitation. As examples the Caspian and the Aral Sea may be mentioned. Other investigators prefer to include on grounds of hydrological and hydrochemical similarities also the continental salt waters which at no time in their history have been in contact with the sea, e.g. the Great Salt Lake in Utah, U.S.A. They regard as brackish all salt waters which have a lower salinity than the sea. According to Schmitz (1959) the differences between the continental and marine salt waters are only of a relative value as both categories have the following four hydrological characters in common: 1. The total salinity is generally between that of fresh and sea water. 2. The waters show often salinity stratification. 3. Horizontal differences in salinity occur e.g. where a river discharges in a salt lake. 4. Large seasonal fluctuations in salinity occur.

    Description: This is a complete revision of this Central and S. American genus, well-known for its cultivated species. The main body consists of a taxonomic revision (text in German, descriptions in Latin); 39 species are keyed out, only one is new, there are I new combination and several new varieties, the latter mostly based on former species; a number of former species have been recognized as hybrids. Localities are very accurately given, often latitude and longitude are added. General chapters include ecology, pollination, palynology (by Dr. Punt), phytochemistry (by Dr. Hegnauer & Dr. Kubitzki), and chromosomes. At the end natural hybrids and those found in gardens are listed, concluded by a listed evaluation of taxa and cultivars found in cultivation. The author concludes that the genus is very homogeneous, also in pollen and chromosomes. This appears also from easy hybridization in which at least 10 species are involved, in culture sometimes even species which are in nature geographically isolated. And hybrids have at least in certain cases proved to be fertile. Even triple hybrids have been found. Because of the very large amount of material studied the species populations and their ranges have become rather clear and hybridization occurs where populations come into contact. From this the author deduces his opinion about the hybrid status of certain specimens. In one biotope only one species occurs and the species are hence replacing either geographically or ecologically. This is obviously comparable to the situation in the genus Geum.

    Description: When working up the material of Biophytum (Oxalidaceae) present in the Rijksherbarium at Leyden I came upon an African specimen which according to the African Floras should be B. sensitivum (L.) DC. It differed, however, considerably from the Asian representatives of that species. Being curious to know whether B. sensitivum (L.) DC. occurs in Africa, which appeared to be important for its geographical distribution in conjunction with my revision of the Oxalidaceae for the Flora Malesiana, I could borrow, thanks to the kind cooperation of the directors of the Royal Botanic Gardens, Kew, and Brussels, a large amount of African material of ‘B. sensitivum’, in all approximately 40 and 150 sheets respectively.

    Description: Cultural experiments with Entophysalis deusta support Drouet and Daily’s concept of this species as a morphologically highly plastic taxon, showing forms traditionally identified as Entophysalis granulosa, Gloeocapsa crepidinum, Pleurocapsa fuliginosa, and Hyella caespitosa. These results are in accordance with observations on populations forming part of the ‘black zone’ of the upper intertidal belt. It is shown that Drouet and Daily’s taxonomic principles, leading to a broad and more natural concept of this species, are sounder than those underlying Geitler’s Cyanophyceae in which several entities included by them in Entophysalis deusta are treated as species.

    Description: As the preparation of an annotated check list of the marine Mollusca of Surinam (Dutch Guiana) will take some more years, it was thought appropriate to publish a preliminary report on the bivalves. This report consists of a list of 126 species with a few notes containing, i.a., the description of seven new species, and a discussion of the local distribution of the marine bivalves. Of the 126 species listed seven are described as new, viz., Nucula surinamensis, Crenella abbotti, Periploma coquettae, Tivela geijskesi, Diplodonta (Sphaerella) rehderi, Lucina (Parvilucina) clenchi, and Mactra (Micromactra) surinamensis.

    Description: In April 1898 the veliid genus Trochopus Carpenter was erected to hold a new halophilous water-strider from Jamaica, described as marinus. The specimens were netted in numbers on standing salt waters beneath mangrove trees in swamps near the head of Kingston Harbour. In August of the same year CHAMPION described the second member of the genus, Trochopus salinus, collected in the mangrove swamps of the Pearl Islands, Gulf of Panama. Subsequently, KIRKALDY (1900) wrongly considered the genus Trochopus to be a synonym of Rhagovelia Mayr (1865), but correctly treated the trivial name marinus as a synonym of Rhagovelia plumbea Uhler. This generic synonymy was largely accepted until CHINA & USINGER (1949) took Trochopus out of synonymy and restored it to its original status. As the trivial synonymy is correct, this makes the genotype Trochopus plumbeus (Uhler) (= marinus Carpenter). Recently BACON (1956) and also MATSUDA (1956) followed KIRKALDY and wrongly repudiated Trochopus as a synonym of the older genus Rhagovelia, including the transfer of plumbeus and salinus back into the latter genus. In the present paper, the authors are in full concurrence with the classification of CHAMPION and of CHINA & USINGER, in which Trochopus is restored to its original status. As here systematized, Trochopus comprises T. plumbeus, T. salinus, and the new species described below from Surinam.

    Description: The Ameiva of the Lesser Antilles present an interesting case of isolated populations of related animals on a chain of islands that differ in size and proximity among themselves but form a geographic group. The situation is made still more interesting by the fact that at times in the Pleistocene the sea was 100 fathoms or more lower, and certain of the islands were then connected by land. The discovery of a new species of Ameiva on Maria Island off the south coast of St. Lucia and the attempt to identify and place taxonomically the three specimens first sent to us by GARTH UNDERWOOD provided the stimulus to a brief re-survey of this neglected but, from a zoogeographic and evolutionary point of view, extremely interesting set of forms. Of this new species we have been able to examine two additional specimens collected by Père ROBERT PINCHON of the Séminaire Collège, Fort-de-France, Martinique, and a series obtained by J. D. LAZELL, JR. in the summer of 1962, as well as 23 specimens collected by A. SCHWARTZ and assistants.

    Description: Mrs. EVELINE DU BOIS-REYMOND MARCUS found the turbellarian described below, which belongs to the Umagillidae (Neorhabdocoela, Dalyellioida), in a vial of Dr. P. WAGENAAR HUMMELINCK’S collection of Caribbean polyclads. The species of Syndesmis are known to live in the body cavity and the intestine, especially the rectum, of sea-urchins, so that the present specimens might have been evacuated together with the faeces. The last revision of the Umagillidae (STUNKARD & CORLISS 1951) was followed by papers of WESTBLAD (1953), HICKMAN (1955, 1956), HICKMAN & OLSEN (1955), and HYMAN (1960). Their results suggest continuing the key of STUNKARD & CORLISS. AS the present species has a simple, not H-shaped, intestine, paired testes, and paired ovaries, the supplement to this KEY is restricted to STUNKARD & CORLISS’ numbers 1-15 of the subfamily Umagillinae.

    Description: The material described below came from washings of holothurians in the West Indies. It was collected in part by the author and Dr. R. U. GOODING during the summer of 1959 in the Bahamas, Barbados, Puerto Rico, and Jamaica. This field work was aided by a grant (G-8628) from the National Science Foundation of the U.S. The rest of the material was collected by Dr. J. H. STOCK in 1958 at Curaçao and Bonaire, with the support of the Netherlands Foundation for the Advancement of Research in Surinam and the Netherlands Antilles (WOSUNA). The study of the specimens has been aided by grants (GB-1809 and GB-5838) from the National Science Foundation. I am indebted to Dr. ELISABETH DEICHMANN of the Museum of Comparative Zoology, Harvard University, for the identification of the holothurian hosts collected in 1958 and 1959.

    Description: The petrography and the structural geology of some parts of the ”Hercynian” orogene of western Galicia is discussed. The oldest rocks are metasediments and orthogneisses which have some relic-structures of an older orogeny. The ”Hercynian” migmatization gave rise to a large series of anatectic granite formations. Three ”Hercynian” phases of deformation, all with a WSW-ENE-directed stress-field, have been distinguished. Younger wrench-faults are originated by the same stress-field. Some fabric analyses show that the first two phases have a sub-vertical, NNW-SSE-striking schistosity, each with a horizontal B-axis, and that the third phase has a vertical N-S-striking cleavage with a vertical B’-axis. The migmatization took place after the first phase.

    Description: Fusulinid faunas from various locations spread throughout the Cantabrian mountains are described as belonging to about 180 species including 17 new species and 11 new subspecies of 18 genera. The latter are Staffella (with 3 new species), Parastaffella (with 3 new species and 2 new subspecies), Millerella, Ozawainella (with 2 new species), Pseudostaffella, Schubertella, Fusiella, Profusulinella (with 1 new species and 3 new subspecies), Aljutovella (with 1 new species), Hemifusulina, Beedeina (with 1 new species and 1 new subspecies), Verella, Eofusulina (with 1 new species), Fusulina (with 2 new species and 1 new subspecies), Hidaella (with 1 new subspecies), Fusulinella (with 3 new species and 3 new subspecies), Obsoletes and Protriticites. The faunas are closely comparable with those of the Eurasian continent, notably of Russia; not only in the species and genera but also in their chronological sequence. The assemblage zones have been subdivided into subzones and subdivisions: Assemblage Zones Protriticites Fusulinella Profusulinella Millerella Subzones B A B A Ps. antiqua Subdivisions B3 B2 B1 The subdivisions and subzones are considered to be only significant for this region where they have facilitated the correlation of many sections. These correlations have been almost invariably confirmed by Racz from his studies of algal floras, and have enabled a synthesis of the general sedimentary history of the Carboniferous Period here. The correlation of the NW European and Russian stages through the Donetz Basin, presented at Heerlen in 1958 is different from that derived from the Spanish floras and faunas. Despite shortcomings in some stratigraphic data the palaeontological identifications are valid and the difference in correlations must be considered significant. This forces the conclusion that some process possibly that of different rates of evolution, existed during this time.

    Description: Cambro-Ordovician clastic sediments varying in composition from microconglomerates to slates occur. A more precise stratigraphic assignment is impossible, because of the lack of fossils and traceable stratigraphic horizons. The Cambro-Ordovician rocks have undergone four Hercynian deformation phases. Each phase was accompanied by the formation of cleavages (slaty, fracture or crenulation cleavage). In the Vail Ferrera area these four deformation phases are well developed. Their relative age relationships were known from other parts of the Central Pyrenees and could be established in many outcrops. The first deformation, accompanied by a regional synkinematic metamorphism and caused by a N-S compression, divided the orogene into (1) the infrastructure (e.g., the Aston massif) with medium to high grade metamorphism and a flat cleavage plane, and into (2) the suprastructure (e.g., the Salat Pallaresa anticlinorium), with low grade metamorphism and a steep cleavage plane. The second phase produced N-S trending folds and was caused by an E-W compression. The third phase made a conjugate fold system in a NW-SE and a NE-SW direction; the asymmetry proves that an E-W compression caused these folds. The fourth phase was produced by a renewed N-S compression and a vertical E-W cleavage was formed. Finally blockfaulting occurred by which the Mérens fault, which seperates the Aston massif from the Hospitalet massif, was formed. A literature study, concerned with the different types of deformation, shows that the direction of the extension can be parallel or perpendicular to the fold axis with transitions in between. Such a ”deformation pattern” is found in the Vail Ferrera area. The relationship between this pattern and the metamorphism is given.

    Description: When the author beheld the tranquility and the magnitude of a Caribbean mangrove-lagoon for the very first time, he was so much impressed by the wealth and the complexity of this habitat that he could not but devote his special attention to a number of simple Cassiopeas, lazily pulsating amidst the turtle-grass. Moreover these Bonairean animals challenged him to further research, because at first view, their appearance showed some striking differences from a description given some years before by STIASNY, with reference to Cassiopeas collected by VAN DER HORST on Curaçao. The result was a lengthy paper “Zur Kenntnis der Scyphomedusen-Gattung Cassiopea” (1933). The present article may be considered as a continuation, except for one thing; several subjects discussed in the first publication will here be omitted. Special attention, however, has been given to the number & shape of radial vessels, and to a few striking characteristics of oral arms & vesicles, which may be considered as being of supra-specific and infraspecific taxonomical value respectively. – Thanks are due to H. C. OBREEN (1958) and MIEKE GODERIE (1966) for their kind assistance within the scope of their student’s practical course in taxonomy.

    Description: Professor Dr. DIVA DINIZ CORRÊA, Head of the Department of Zoology of the University of São Paulo, was able to work at the “Caraïbisch Marien-Biologisch Instituut” (Caribbean Marine Biological Institute: Carmabi) at Curaçao from December 1965 to March 1966, thanks to a grant received from the Government of the Netherlands. There she collected 26 species of Polyclads, and took notes of their shapes and colours. Furthermore Dr. PIETER WAGENAAR HUMMELINCK, of Utrecht, sent us a large collection of polyclads from the Caribbean area, gathered on his trips from 1930 to 1964. He had also collected in 1963 in the Miami area. We received some samples from the latter area from Prof. Dr. CORRÊA and Prof. Dr. FREDERICK M. BAYER, of Miami. Drs. LILIANA FORNERIS, WALTER NARCHI, and SÉRGIO DE ALMEIDA RODRIGUES, all of São Paulo, gave us interesting Brazilian material.

    Description: Four Upper Carboniferous limnic coal basins in the Cantabrian mountains are described. In the coal measures, which are known as the Cea formation and unconformably overlie the Older Palaeozoic, two sedimentary cycles are recognised. Accordingly, the unconformable sequence is subdivided into two members. The lower one, the Carrión member, starts with quartzite conglomerates and becomes gradually finer grained upwards. It yields anthracitic coal and upper Westphalian D floras. Its maximum thickness is 1200 m. The upper one, the Prado member, begins with limestone conglomerates and also grades to finer sediments upwards. It contains dry to fat coals and Stephanian A to B floras. Its maximum compiled thickness may be approximately 2500 m but a complete section is not found anywhere. The Cea formation shows onlap onto the Older Palaeozoic towards the west. The predominant structural trend in the Cea formation in the described area is east-west. A few structures with north-south axes were recognised in the Valderrueda and Ocejo basins. They are thought to have originated from differential compaction and to be the earliest structures of the Cea formation. The east-west structures are dominated by wide, asymmetric synclines, separated by narrow zones of disturbance instead of anticlines. They have originated as a secondary effect of block faulting in the underlying Older Palaeozoic formations. In the history of the Cea formation large east-west trending fundamental faults (terminology from de Sitter, 1956), probably separating basement blocks, play a dominant role in the deposition as well as in the deformation of the Cea rocks. Activity along these large east-west faults in the Older Palaeozoic rocks is proved to have continued intermittently from the upper Westphalian (and earlier, Rupke, 1965) to the middle Tertiary. Thus the deformation of the Cea deposits, which is dependent on the movement along these faults, must have been a long-lasting process and not a short-lived event like, for instance, the Permian Saalic phase, as was formerly believed.

    Description: The mineralizations of Fe, Cu, Li, Sn, W in W. Galicia are discussed. Sulphidic mineralization of Fe and Cu is exemplified by a description of the mine of Fornás (SE. of Santiago de Compostela). Field and laboratory data (including geothermometry of the phases of the Fe-Zn-S system) suggest that the deposit has been subjected to regional metamorphism of amphibolite facies grade. Li-bearing pegmatites (with spodumene, petalite, montebrasite, beryl, cassiterite, columbite and alteration products) are locally rather common in the area. It is argued that they have intruded as masses of silicate melt along faults. Cassiterite and wolframite are found in quartz veins with pockets of alcaline feldspar, suggesting a genetic relationship with the pegmatitic rocks. The mineralized dykes and veins are related to the hercynian two-mica granites. In Portugal similar mineralizations are considered to be connected with post-tectonic biotite granites. Alternative explanations of this apparent discrepancy are given. A primera vista la mineralización en Galicia no parece muy complicada. Se presentan dos tipos principales relacionados especialmente con dos unidades petrológicas: 1) los yacimientos de sulfuros de hierro y cobre asociados con el complejo máfico (el lopolito) y, 2) la mineralización de litio, estaño y wolframio asociada con los granitos.

    Description: The broad outlines of the taxonomy and distribution of the Antillean ameivas have been sketched by BARBOUR & NOBLE (1915). Two principal ancestral stocks were recognized: (1) One gave rise to the Ameiva ameiva group whose center of origin and dispersal was northeastern South America, and which extended westward into Central America and also up the Lesser Antilles to Puerto Rico and Hispaniola.¹ (2) The other gave rise to the Ameiva undulata group which originated in and dispersed from Central America, moving into northwestern South America and into the Greater Antilles as far eastward as Hispaniola. In addition to these two main stocks, they postulated still a third origin for a small group of species in the Bahamas – Puerto Rico – St. Croix area (A. maynardi, A. wetmorei and A. polops), but which they allied more closely to the A. undulata than to the A. ameiva group. A final, somewhat problematic group consists of the South American Ameiva bifrontata and its subspecies. They postulated that it either arose from the Ameiva ameiva group or from still a fourth stock. Accordingly to BARBOUR & NOBLE’S view, then, the Antilles comprise two main groups which have invaded the area from opposite directions and which overlap on Hispaniola (or from Hispaniola to St. Croix if Ameiva wetmorei and A. polops are considered allied to the A. undulata group – see below).

AITKEN (Trinidad Regional Virus Laboratory, Port-of-Spain) has provided several new records, and Mr. A. VENTURA (University College of the West Indies, Kingston), has supplied additional records of Eutrombicula batatas in Jamaica. – The bat hosts collected by HUMMELINCK have been identified by Dr. A. M. HUSSON (Rijksmuseum van Natuurlijke Historie, Leiden). In all, our knowledge of trombiculid mites in the Caribbean has been substantially increased. Forty-five species are now known from the West Indies and chiggers are recorded for the first time from Saint-Barthélemy, Dominica, Patos Island (Venezuela), Margarita, Curaçao and Aruba.

    Description: In a high Andean valley (6°N. Lat., alt. 3800 to 4400 m) four bodies of glacial drift marked by many end moraines are recognized. Stratigraphically related to the drifts are small bodies of lake sediments, from which core- and outcrop samples were taken. The samples yielded a continuous pollen sequence from which climatic history was derived. The pollen sequence is calibrated by nine C14 dates from organic material in the samples. The dated climatic history permits correlation of the sequence with both Colombian pollen zones and northern European zones. It also permits approximate dating of the drifts, which are in good chronologic agreement with those recognized in North America. The results therefore support the view that major climatic events in high-altitude, tropical South America during at least the last 12,000 years were synchronous with those in mid- and high-latitude North America and Europe.

    Description: This paper describes some features of the carapace of two hollinid ostracode genera: Hollinella and Jordanites. The carapace of these ostracodes consists essentially of the same layers as modern ostracodes, with exception of the velar structures. A survey on the ontogeny of species of Hollinella and Jordanites reveals that this is very similar to the ontogeny of other palaeocopid ostracodes. It is suggested that Hollinella and Jordanites were marine near-bottom swimmers. The velum probably served to prevent the animal from sinking too deeply into a soft substrate. Five species of Hollinella, including three new species, and three species of Jordanites are described. All species are restricted to the Upper Carboniferous of NW Spain.

    Description: In 1968 continuous seismic profiles with a total length of 150 km were made in the Ría de Arosa (Galicia, NW Spain). They were executed by the Bundesanstalt für Bodenforschung (Hannover) with the assistance of two members of the Department of Geology of the University of Leiden (The Netherlands). The pneuflex (airgun) system used for profiling is described. The transformation of travel-time profiles into depth profiles was done automatically with the aid of a computer program. The profiles reveal the presence, below some 7—12 m of Holocene marine muds, of bedded deposits with a thickness of about 30 m (and in the outer part of the ria even more than 60 m), which are interpreted as being of fluvial origin. They are underlain by what is assumed to be colluvium and weathered granite. The bedded deposits must have been formed in times when the sea-level was low, presumably during the Riss and/or Würm glacials. They may originate in part from deposits of the Ulla River, but to a greater extent may represent fluvial fans of its tributaries.

    Description: The Devonian and Carboniferous rock-sequence in the Cantabrian Mountains is developed in two different facies which are separated by an E-W tectonic line, the León Line, and called the Leonide and Palentian facies, respectively to the S and N. The Leonide facies is widely exposed throughout the Cantabrian Mountains and its tectonic history is now well known. The most complete sequence of the Palentian facies occurs in the present area, which lies across the boundaries of the provinces of Palcncia, León and Santander. Towards the west and north the Devonian and Lower Carboniferous gradually plunge below the younger strata. The Palentian facies in this region is only found north of a second fundamental tectonic feature, the SE-NW Cardaño Line. This line joins the León Line in the SE of the area near the village of Santibañez but can be traced far to the NW into the province of Oviedo. Immediately south of the Cardaño Line there is the Sicro basin filled with Upper Carboniferous elastics which even overlap in places the León Line further south. The pre-Westphalian rocks of the present area are limited to the north by the Peña Prieta Line, the fundamental nature of which is emphasised by a large granite intrusion. To the east the Polentinos fault separates the present area from the mainly Westphalian, Pisuerga basin. The fundamental lines are partly expressed at the surface as large fault systems. It is remarkable that in the Palentian facies sedimentation was not interrupted by the major erosional periods known from the Leonide facies. The post-Silurian and pre-Westphalian sequence of the Palentian facies is on average about 850 m thick and consists mainly of shales with thin limestone intervals. The corresponding sequence of the Leonide facies is on average about 1750 m thick and shows important, thick Devonian reef limestone intervals. Only the lower and uppermost of the Devonian contain clearly higher-energy deposits (sandstone sequences). Both the lithology and fossil association confirm that the Palentian facies sequences developed in a more offshore (middle to outer neritic) environment of deposition than indicated for the Leonide facies (littoral to inner neritic), Important epeirogenetic movements in the late Namurian and in the Westphalian disturbed the preceding long period of quiet sedimentation. Between the Cardaño Line to the south, the Peña Prieta Line to the north and the Polentinos fault to the east the Cardaño block was subjected to a regional tilting during the deposition of the rocks of the Yuso Group. The maximum uplift and erosion are indicated in the N and E whereas the deepest subsidence and maximum deposition have been detected in the S and W of the Cardaño block. The pre-Westphalian rocks, where unconformably overlain by those of the Yuso Group, show local, gentle, pre- or synsedimentary folded structures. The present study has not revealed pre-Westphalian structures that would justify the use of the term orogenic phase (i.e. Sudetic) for their origin. They are rather interpreted as the results of local compression accompanying pre- and synsedimentary epeirogenetic movements. The unconformable Yuso Group consists of a conglomerate facies — the Curavacas Formation — up to about 700 m thick and a sandstone-shale facies — the Lechada Formation — of at least 750 m N of Cardaño de Arriba (probably up to 2000 m to the W). The Westphalian rocks were deformed during the main compressive phase, which therefore is thought to correspond with the Asturian folding phase (pre-Stephanian). The tectonic transport here was from north to south in contrast to the Leonides where it was from south to north. This correlates with the theory that the folding of the two areas took place at different times; Asturian in the Asturides (Palentian facies) and Sudetic in the Leonides. The inhomogeneity of the Palentian facies rock sequence is reflected in the very complicated final tectonic picture. The Cardaño Area can be subdivided into 4 subareas (Northern, Central, Southern and Arauz), in each of which a different lithofacies is related with a corresponding minor tectofacies. Simultaneous cross folding can be related to the rapid facies changes in the affected rocks. The present area gives very instructive examples of the close interaction of tectonics and sedimentation. Epeirogenetic movements between fundamental tectonic lines controlled the deposition of the sedimentary sequence. These heterogeneous rocks were then acted upon by a relatively short compressive tectonic phase which created out of them the present architecture of the Cardaño Area.

    Description: The Laguna de La Herrera (alt. ca 2550 m) is a lake situated on the western border of the Sabana de Bogotá, near Mosquera (dept. of Cundinamarca, Colombia) (fig. 2). This part of the Sabana has a relatively dry climate (appr. 600—700 mm rainfall), as it lies in the rain-shadow of the hills that border the Sabana on its western edge, and it bears therefore a xerophytic vegetation. The western slopes of the bordering mountains, that fall steeply to warmer valleys, have a much higher rainfall and are almost continuously clouded. They bear therefore a cloud-forest, of the Quercetum type, that reaches partly the very top of these mountains. Fig. 1 shows this in an idealized section. For further details on the mentioned vegetation-types, we may refer to van der Hammen & Gonzalez (1960). In the same publication the Geological history of the Sabana is shortly described, including the Quaternary history as a big lake with fluctuating water-level. Geological data on the area of Laguna de La Herrera were given in van der Hammen & Parada (1958). The present section of the pollen diagram corresponds approximately to bore-hole no. 19 of fig. 2 of that publication. The origin of the lake is probably (at least partly) due to fluvial erosion and sedimentation (old course of Rio Balsillas?). The lake sediments consist principally of diatom gyttja with intercalated layers of clay or peaty material. The base consists of hard greenish to white clay. We believe that this clay possibly corresponds to the altered clays that are exposed in the nearby hills, and which belong to much older eroded lake-sediments (see van der Hammen & Parada, 1958). The only other existing pollen diagram from the Holocene of the Sabana is from near Bogotá, near the eastern border of the Sabana (section CUX upper part, fig. 7 of van der Hammen & Gonzalez, 1960). Nevertheless, that diagram shows a completely different picture, reflecting a local vegetation (it is not from lake-sediments), under much more humid conditions (alternation of Alnetum and Myricetum). A direct comparison of the diagrams of Bogotá and La Herrera is therefore difficult.

    Description: A study of the beaches on the NW shores of the Ría de Arosa was made with respect to shape and structure of the beaches, grain-size distributions, heavy mineral associations, and relations of the heavy minerals to the bedrock of the hinterland. Most of these numerous small beaches are situated in inlets determined by the occurrence of relatively weak bedrock (mostly schists). Grain-size generally fall in fractions 〉 50 µ, and some beaches even contain important amounts 〉 2000 µ. Many grain-size distributions are bimodal owing to the mixing of different beach layers by wave action or, in a few cases, to mixing with fluvial sands. The heavy mineral compositions of the fluvial and beach deposits approximately reflect the mineral compositions of the bedrock, especially in the deeper inlets of the Ría, whereas most of the beaches on the more exposed parts have a more varied heavy mineral composition. In some cases the minerals indicate a weak long-shore transport of the sands.

    Description: The Carboniferous Pisuerga basin developed north of the León line and as such is the most eastern one of the Asturide basins. The Carboniferous sequence is subdivided into Ruesga Group (roughly Lower Carboniferous + Namurian), Yuso Group (roughly Westphalian) and Cea Group (roughly Stephanian). Since the beginning of the Yuso Group the Pisuerga basin became subdivided into a western and eastern basin and since the beginning of the Cea Group the western basin became subdivided into two separate basins. The main folding started during the Stephanian. A remarkable interaction of epeirogenic and orogenic movements leads to the analysis of a close relation between sedimentological and structural features. Several pronounced structural lineaments can be traced to have been active since the Middle Devonian into the Tertiary.

    Description: A continuous sequence of Devonian sediments is exposed in the northern part of the province of Palencia (NW-Spain), on the southern slope of the Cantabrian Mountains. This study concerns the stratigraphy and paleontology of the Lower Devonian formations. At the base of the sequence a clastic formation is found, called the Carazo Formation. This unit can be sub-divided into three members, from top to bottom: (c) alternating shales and sandstones, (b) quartzitic sandstones, partly strongly ferruginous, (a) shales and micaceous sandstones. Members a and b did not yield fossils. The upper part of the formation is richly fossiliferous. The main element of the fauna consists of brachiopods, which occur together with tentaculites, trilobites, ostracods, and pelecypods. The well-preserved and characteristic brachiopods are illustrated. The fauna indicates a Lower Gedinnian age for these sediments. The next lithologic unit, called the Lebanza Formation, consists of some 100 metres of well-bedded limestones with shale intercalations at the base and top of the formation. This formation is extremely fossiliferous. Brachiopods dominate; tentaculites, trilobites, pelecypods, corals, stromatoporoids, bryozoans, and crinoid stems also occur. The diagnosis and systematic position of 18 of the brachiopods are discussed, viz. 3 dalmanellids; 7 rhynchonellids, including 3 new species; 4 terebratuloids; and 4 rostrospirids. Special attention is paid to the internal structure which was studied in serial sections by means of the peel technique. Drawings of the more important sections are given with each diagnosis. In total, 25 species were determined in the brachiopod assemblage. Different assemblages occur in the upper and lower parts of the formation. The association in the lower part gives no definite indications about the age of these rocks. With their stratigraphical position taken into account, an Upper Gedinnian to Lower Siegenian age is concluded. The upper part of the formation shows only typical Siegenian species. On account of the correspondence with faunas of the Middle Siegenian formations of the Massif Armoricain (Brittany, France), the age of this part of the formation can be established as Middle Siegenian. The correlations with sequences in adjacent areas are discussed. There is a marked divergence from the brachiopod succession in other parts of the Cantabrian Mountains, due to different oecological factors.

    Description: The present investigation is a systematical treatment of the sporomorphs from strata at the Jurassic-Cretaceous boundary in the eastern Netherlands Twente area, and an attempt to apply palynology to detailed stratigraphical study, by making use of quantitative pollen analyses. The rock samples used have been derived from two drilled sections in the eastern Netherlands, each of them representing the uppermost Jurassic and lowermost Cretaceous. The sediments are part of the sequence belonging to the Mesozoic Lower Saxon Basin; they contain the so-called ”Wealden” beds, the age of which is not exactly known. Two pollen diagrams were composed from the analyses and show major pollen fluctuations, which are most probably to be regarded as a consequence of long-range oscillations of vegetational belts near the western border of the Lower Saxon Basin. The purpose of the investigation has been to establish the time-stratigraphical position of the ”Wealden” more precisely and furthermore, to establish major quantitative frequency changes in the pollen flora at the Jurassic-Cretaceous boundary. For this purpose the diagrams have been divided into nine pollen zones R to Z, based on first and last occurrence of sporomorph species. The ”Wealden” section contains nearly three zones (V to X). Recent correlation in several European stratigraphical sequences, based on ostracods, have shown that the Jurassic-Cretaceous boundary in the Dutch-German stratigraphy may be located between the base of the Serpulite and the upper limit of ostracod zone ”Wealden” 4, with strong indications that it might even be placed in a much less extended interval, ranging from the uppermost Serpulite to the base of ostracod zone ”Wealden” 2, that is to say from the base of pollen zone V to the base of pollen zone W. The present investigation in the field of palynology takes also into consideration the rhythmic fluctuations, shown in the pollen diagrams from the eastern Netherlands. Similar fluctuations were recorded in the pollen flora from Maastrichtian and Paleocene strata in Colombia, South America. They are attributed to regular oscillations of the climate at timeintervals of approximately 2.3 million years and 7 million years. These rhythmic fluctuations were also recorded in the sedimentary history of the Eastern Cordillera in Colombia during the Cretaceous; they are assumed to originate from regular sea-level oscillations, taking place synchronously with the Cretaceous ages at time-intervals of around 7 million years. Applying this theoretical time-scale to the pollen diagrams from the eastern Netherlands, it might be possible to attribute the rhythmic oscillations, shown in the Dutch pollen flora, to time-intervals of approximately 2.3 million years. In this case the Berriasian occupies 3 cycles immediately underneath the Valanginian, that is to say the pollen zones X and W, and possibly also zone V. The Jurassic-Cretaceous boundary might then be located at the base of zone W or the base of zone V. This agrees with a major change in the quantitative and qualitative composition of the pollen flora, and with the results of the correlation based on ostracods.

    Description: In the Cantabrian Mountains stromatoporoids only have been found up to now in Devonian formations. They occur together with tabulate and rugose corals and brachiopods. Together with these organisms they form biostromes or just biogenetic layers of brecciated and overturned colonies. Four primary microstructures could be distinguished: compact, microlaminate, ordinicellular, and cellular. Alteration seems to begin before fossilization in many cases: the microtissue becomes flocculent by migration and/or destruction of specks. After fossilization the microstructure is altered mainly by migration of specks along slip planes and by rearrangement of the calcite crystals. In this paper the original microstructure is used as the main character for the determination of genera. The form of the coenosteum and features of the gross structure such as superposition of pillars, absence or presence of ring pillars, spacing of laminae and pillars, and others, are strongly influenced by ecological factors. Therefore they cannot be used as characters for the definition of genera and often not even for species. Four genera can be distinguished in the Spanish material: Actinostroma (compact with continuous pillars), Stromatoporella? (microlaminate), Stromatoporella? (ordinicellular) and Stromatopora (cellular). The genera Geronostroma and Atelodictyon are considered to be synonyms of Actinostroma. The genus Stromatoporella should be divided into two genera: one genus with microlaminate and one genus with ordinicellular microstructure. In the microlaminate genus the genera Clathrocoilona, Trupetostroma and Stictostroma (partly) should also be included and perhaps Idiostroma (partly). The ordinicellular genus can be combined with part of the genus Stictostroma and some species of Anostylostroma. The genera Parallelopora and Ferestromatopora are considered to be synonyms of Stromatopora. For the determination of species an attempt is made to establish the variability of the gross structure for each species. As this variability seems to be rather wide, species determinations are only given when sufficient material was available. The following species are described: Actinostroma papillosum (= A. clathratum), Actinostroma verrucosum?, Actinostroma stellulatum, Stromatoporella? granulata? (microlaminate), Stromatoporella? selwyni (ordinicellular), and Stromatopora huepschi?. Stromatopora concentrica

    Description: In this article the results of a pollen analytical investigation of a section in the tropical lowland of Colombia are discussed. The section has been taken from a lake in the lower course of the River Magdalena (fig. 1). This lake, called ”Cienaga de Morrocayal”, is situated about 20 metres above sea-level; the section represents the greater part of the Subatlantic, and in the course of this period there was a succession of humid and drier periods. These fluctuations seem to represent a cyclic phenomenon. Two C14 analyses of charcoal-samples from the peatlayers, found in this section, showed that these layers were formed at about 1470 A.D. and about 1230 A.D.

    Description: The structures in the SW part of the Cantabrian Mountains have much in common with those of the Foothills Belt of the Rocky Mountains, the Alps and the Central European Hercynian orogene, and their origin can be explained in the same way as that of the structures in these orogenes. The greywacke sedimentation and the folding both migrated from the internal to the external part of the original basin during the Upper Carboniferous. The folds and thrust faults run parallel to the axis of the original basin. The basement has been broken into large blocks in the shape of parallelograms, along the boundary faults of which local deviations of the regional directions occurred.

    Description: The investigated area forms part of the crystalline basement of the southwestern half of the Iberian peninsula (Hesperian Massif). In it, Precambrian paragneisses of predominantly greywacke composition surround granite-gneisses with whole-rock Rb-Sr ages of 486-500 m.y. Hercynian granites are intrusive into the older rocks. It is argued that the paragneisses underwent a Barrovian type regional metamorphism (probably low P-T portion of the almandine-amphibolite facies) in the Precambrian, were locally thermometamorphosed by some types of the Cambro-Ordovician granite complex, while in the hercynian orogeny they were again subjected to regional metamorphism, but now of the Abukuma-type (andalusite-cordierite-muscovite subfacies of cordierite-amphibolite facies). The Precambrian metamorphism is represented by elongated quartz, biotite flakes and relics of garnet, all enclosed within early-hercynian minerals, the thermometamorphism by altered, fine-grained cordierite and by fine-grained rock structures, the hercynian metamorphism by the occurrence of cordierite, andalusite and cummingtonite, in appropriately composed rocks, on a regional scale. The granite-gneiss complex consists of per-alkaline gneiss (containing quartz, albite, microcline, riebeckite, aegirine, lepidomelane, astrophyllite, zircon, fluorite, xenotime, pyrochlore and some less frequent accessories), biotite gneiss (composed of quartz, microcline, plagioclase, biotite, occasionally muscovite or green amphibole, accessories) and a hybrid series of basic rocks both enclosed within and assimilated by alkaline granite-gneiss. Evidence is presented in support of the hypothesis that the per-alkaline gneisses were onefeldspar granites before their (hercynian) gneissification, which caused separation of the perthites into very pure albite and microcline, both in the maximum low-temperature state and that riebeckite in its present composition was not an original constituent of the per-alkaline granite either. Considerations on the stability of riebeckite, aegirine and lepidomelane yield P-T conditions compatible with those deduced from the paragneiss mineral assemblage. Sodium, apparently mobile after the separation of the perthites into their composing minerals, migrated into neighbouring rocks, causing the formation of albite porphyroblasts. The influence of prehercynian alkali metasomatism from per-alkaline granite is also locally visible. The hercynian megacrystal, muscovite, two-mica and coarse-grained biotite granites and cordierite-quartzdiorite are petrographically described and their origin and mode of emplacement discussed. Chemical analyses were made of paragneiss, metasomatosed paragneiss, per-alkaline gneiss, amphibolites, rocks of the hybrid series and of microcline, riebeckite, aegirine and lepidomelane. Optical data of albite, microcline, riebeckite, aegirine, lepidomelane and cummingtonite and X-ray data of albite, microcline, riebeckite and aegirine are given. Of microcline and riebeckite the cell parameters were calculated.

    Description: The myicolid copepod Pseudomyicola spinosus is reported from 22 new hosts (pelecypods) in Bermuda and the West Indies, from 1 new host (a pelecypod) in Madagascar, and from an ascidian (Pyuridae) in Curaçao (probably an accidental association). P. spinosus is redescribed, based on specimens from Isognomon alatus in Bermuda. Among 316 P. spinosus from Bermuda, Puerto Rico, Jamaica, Barbados, Brazil, Senegal, Madagascar, and Jugoslavia the dimensions of the body and caudal ramus varied widely. The ornamentation of the anal segment showed four different conditions of spination, and sometimes included an extra long ventral setule on either or both sides. The specimens studied are regarded as one species, P. spinosus, without apparent subspecific differences. The following are considered as synonyms of P. spinosus: P. glaber Pearse, 1947, Myicola tageli Pearse, 1947, P. anomalocardiae Narchi, 1965, and P. mirabilis Humes, 1959.

    Description: Die Geburt der Laboratoriumratte wird kurz beschrieben. Das Fressen der Nachgeburt ist nicht notwendig für eine gute Milchsekretion. Die Feten liegen in gekrümmter Haltung in der Gebärmutter, aber werden während der Austreibung gestreckt. Die Austreibung erfolgt nicht immer abwechselnd aus den beiden Uterushörnern. Die Trennung von Plazenta und Uteruswand wird von der Wehentätigkeit herbeigeführt. Durch eine Verschiebung im Bindegewebenetzwerk unter der Plazenta ändert sich die Struktur, sodass diese flache Schicht einen relativ hohen Wulst bildet. Die zirkulär verlaufenden collagenen Fasern bekommen deshalb nach Lösung der Plazenta einen radiären Verlauf. Die Rückbildung dieses Bindegewebewulstes wird beschrieben. Makrophagen spielen dabei eine wichtige Rolle. Nach etwa 5 Monaten ist die Rückbildung vollständig und ist die Narbe nur noch an einer kleinen haemosiderinreichen Stelle erkennbar. Der Epitheldefekt wird etwa 48 Stunden nach der Geburt geschlossen. Unmittelbar nach der Geburt zieht sich die Wunde zusammen infolge der Verschiebung im Bindegewebenetzwerk unter der Wunde. Eine halbe Stunde nach der Geburt faltet sich das Epithel über die Wundränder. Etwa 22 Stunden nach der Geburt findet eine Abflachung der Epithelzellen statt und wenige Stunden später treten die ersten Mitosen auf. Bei der Uterusinvolution der Ratte spielen also mehrere Faktoren eine wichtige Rolle. Die älteren Autoren haben häufig nur ein oder zwei dieser Phaenomene beschrieben. Wir konnten tatsächlich alle in der Literatur erwähnten Möglichkeiten, mit Ausnahme der Neubildung von Epithelzellen aus Bindegewebezellen, bestätigen. Es handelt sich hier aber nicht um eine Frage nach der Richtigkeit der verschiedenen Auffassungen, denn nach unseren Befunden treten die einzelnen Prozesse zum Teil zu gleicher Zeit auf, zum Teil auch finden sie nacheinander statt in einem und demselben Uterus.

    Description: The present paper gathers the results of a morphological study on 149 specimens of Rhinolophus hipposideros, and of ecological investigations on additional material, incl. some 5,000 banded individuals of the same species. Brief description of the reproductive organs of both sexes is given. The reproductive organs of the sexually mature (adult) and the sexually immature grown-up (subadult) individuals are illustrated and comments are made on their changes during the year. In adult males, the spermatogenesis commences in spring, after the change from winter torpidity to active life, and culminates towards the end of July and in August. During the winter months (December to April), the seminiferous epithelium of the tubules of testes is resting. On the contrary, the interstitial cells of Leydig are conspicuously developed in the period from October to April (or May). The tubules of the epididymides of adult males are never entirely free of spermatozoa but they contain the lowest numbers of the latter at the period of intensive spermatogenesis. Towards the end of August and in September, the tubules of the cauda epididymidis begin to be filled with greater numbers of spermatozoa, being overcrowded with them in the period from October till April. Apart from the ampullar glands, the seminal vesicles, the prostate and the bulbourethral or Cowper’s glands, the males of R.h. possess a conspicuously developed accessory sexual gland, discovered, in Rhinolophus, by ROBIN (1881b) and termed the glandula urethralis. This gland is the greatest element of the male genital tract, being at the peak of its secretory activity in October and November. The staining properties of the secretion of this gland indicate that the urethral gland takes an important part in the origin of the female vaginal plug. Most of the adult females were found to copulate already in autumn, from late September till November. Ovulation takes place in April, still before the dissipation of the vaginal plug. Pregnancy lasts for about 2½ months; lactation, for 4 to 5 weeks. The main information on the course of estrous cycle was obtained by histological examinations of vaginal epithelium. The following is the succession of the individual phases of the estrous cycle of reproducing female R.h. in Czechoslovakia: proestrus, late August and early September; estrus, late September till early April; pregnancy, late April till first days of July; lactation, July and early August. The life of R.h. can be divided into three main periods, viz., the juvenile, subadult and adult period. The juvenile period lasts about two and a half months, from July till September. The pelage of individuals younger than some 14 months of age is grey, that of older ones being greyish brown to brown in colour. The male R.h. attain sexual maturity at an approximative age of one year and are first capable of fertilizing at the age of about 15 months, in the second autumn of their life. While the first signs of estrus appear in female R.h. already at the age of 4 months, most of them attain sexual maturity only towards the end of the second year of their life. A small percentage of females (15%, according to banding results) reproduce already at the end of the first year of their life. Although the uterus of one pregnant female R.h. was found to contain two embryos, our results indicate that the litter size equals one. The greatest longevity of R.h. in Czechoslovakia, determined by banding, is 10½ years for males and 9½ years for females. A certain percentage of adult females (6.7% of the material examined) do not reproduce. Sex ratio among the juveniles is 1 : 1 while males predominate among the subadults and, especially, adults; however, a question arises of the extent in which the sample obtained corresponds to the actual relations in the population. The paper is concluded by a discussion. The main problems arising from the study are discussed, viz., the possible hormonal regulation of the male sexual activity, the estrous condition of females, especially during hibernation (the so-called “subestrus”), and the time of attaining sexual maturity.

    Description: Extensive reports on losses in zoo animals are very rare. As fas as we know only London, Paris, Philadelphia and Washington give yearly reports. Of these London and Paris give very complete information. One of the reasons that so few zoos publish their results may be that it is always more pleasant to give information about successes than about failures. In our opinion, however, it is no use to disguise the truth and for other zoos it can be very useful to have the opportunity to compare results. The period described in this paper is part of an important era in the history of our zoo, a period of reconstruction, rebuilding and, of increasing the collection. This period will last another 10-15 years or so as at that time the really old and worn-out buildings will have been replaced and appropriate facilities for the veterinarian will have been achieved. At the same time this period has seen great advances in veterinary care. The Cap-Chur pistol in use in our zoo since 1960 made injection possible of any animal at any time. The increasing arsenal of therapeutics and the international contacts by way of the international symposia on diseases of zoo animals have contributed largely to a better medical care of zoo animals. Thus prevention of diseases is becoming more and more important. In our opinion the effective disinfectant halamid (Chloraminum) plays an important rôle in this respect.

    Description: In a same macroclimate on the islands of the Leeward Group of the Netherlands Antilles two types of vegetation are chiefly found. A vegetation pertaining to the dry evergreen formation series on limestone and a vegetation on diabase belonging to the seasonal formation series. Study was made of the water relation at the end of the rainy season during which transpiration, water deficit, suction pressure and soil water were investigated. From the course of transpiration curves it was concluded that water relations in diabase soil are more sever than those in the limestone. Water deficit in plants, growing on diabase appears to be much higher than those of limestone. Suction pressure divergates strongly in both cases. In the upper soil layers the amount of water that can be taken up by plants is small both in limestone and diabase. In deeper layers of the limestone soil there is more water than in diabase of the same level. Vegetation on diabase is determined by a sufficient amount of water in the soil during the rain season and a great drought during the other months. On the other hand in limestone the amount of water in the soil is larger during a longer period. Because of the higher suction pressure of this soil only plants developing a higher suction pressure can occur.

    Description: Cornelis Elisa Bertus Bremekamp was born at Dordrecht on February 7th 1888. He is therefore now just past eighty, and he has been a member of the Koninklijke Nederlandse Botanische Vereniging for sixty years. He studied at the Utrecht State University and, like many of his contemporaries, was strongly attracted to plant physiology under Prof. F. A. F. C. Went’s influence. Phototropy and geotropy had become the principal fields of research in Went’s wellequipped laboratory, and Bremekamp’s first scientific work was also devoted to these subjects. His thesis (1912) dealt with the Geotropy of Twining Plants. His publications of the following years were the results of similar studies. In the same year he left for what was then the Dutch East Indies where he was first employed at the Java Sugar Experiment Station; then, until 1921, he taught at the Medical College (N.I.A.S.). After returning to the Netherlands he lectured from 1921 to 1923 on plant physiology at the University of Amsterdam. During these years, too, his scientific work was mainly devoted to phototropy and hydrotropy. In 1924 he accepted a position as professor of botany at the Transvaal University College, South Africa. Initially his research there was also in plant physiology, but, perhaps partly under the influence of local conditions, partly through some shift in his interest, his work became gradually oriented toward morphology and systematics. Certain physiological problems in the Rubiaceae drew his attention to that family (Revision of the South African species of Pavetta). In 1930 he was on leave in the Netherlands. It was on that occasion that I first met him, when he attended the awarding of a Ph. D. to one of his South African students. I had long been familiar with his name. For all students studying with Prof. Went thorough knowledge of the scientific work of “Went’s school” was compulsory. Went’s pupils from the days before the First World War were the scientific models that we tried to follow. Names we pronounced with some awe were, beside Bremekamp, Blaauw, Mrs. Rutten-Pekelharing, Arisz, etc. Meeting Bremekamp and being in his company at a dinner party greatly impressed me. Since that time I have known that Bremekamp was a source of information who would take great pains to answer a question as well as possible.

    Description: In material of Cardamine pratensis from many localities in the Netherlands, the following somatic chromosome numbers were counted: 28, 30, 31, 32, 34, 36, 38, 39, 45, 46, 52, 53, 54, 56, 58, 59, 60, 62, 64, 64 à 66, 67, 68, 69, 70, 72, 73, 74, 75, 76, 78, (80), 84, and (118) 1). Many numbers were due to intra-individual deviation of the normal number. As main groups tetraploids with 28-32, octoploids with 56-64, and decaploids with 70-80 chromosomes could be distinguished; the normal numbers of the ploidy levels were 30, 60, and 74-76, respectively. Two subspecies could be distinguished on the basis of morphological, ecological, and cytological characters.

    Description: This paper forms a part of the general study of the Subtribe Paronychiinae undertaken by the author for his doctoral dissertation. The publication of the new taxa, in a separate form, has been necessitated by the fact that the Flora of Turkey, covering the Family Caryophyllaceae, is to be published in the near future, at any rate before the author can present a consolidated account of the results of his own study of the group. The present paper deals only with the diagnosis and description of the new taxa, presented in a rather conventional manner, and no attempt is made to go into details of the various morphological and taxonomic problems pertaining to the genus Paronychia as a whole. Such problems will, of course, be taken up in the general revision of the group.

    Description: The present paper, the first of a series of four on the biosystematics of the Dutch halophilous species of Spergularia, reports the results of a study of the morphological variability of S. media by means of a number of population samples from all parts of the Dutch area, supplemented by the rearing of plants from seed samples in the experimental garden. The seeds of S. media are usually winged, but in the area of the Dutch North Sea Islands, sometimes populations are encountered containing up to 70% plants with exalate to subalate seeds. The development of the seed wing is chiefly determined by genetic factors, but to some extent modifiable by different environmental conditions. The seed wing is too variable to be of decisive diagnostic value to distinguish S. media from S. marina. Plants with exalate to subalate seeds produce seedlings that are significantly smaller than the seedlings of plants with broadly winged seeds. Fruit- and calyx lengths vary too widely to be of diagnostic value either. The number of stamens plus staminodes is usually 10, rarely 9; the number of fertile stamens is 8 to 10 in nearly all flowers of a population, but may be as low as 0 to 3 per flower in some individual plants. The number of fertile stamens is primarily determined by genetic factors. The growth habit and the vegetative characters appear to exhibit only phenotypic variation.

    Description: In the summer of 1966 three students, bachelors in botany, of the State University of Utrecht, Netherlands, made botanical investigations in the Angmagssalik area (65° N.lat.-67°20' N. lat.) in South-east Greenland. The main purpose was to carry out floristical and ecological investigations, while special attention was paid to the altitudinal belts in the vegetation on mountain slopes. The fieldwork will be continued in 1968. From the botanical collection the lichens were identified by the author and are listed here, except some critical species of which the determinations have not been finished yet. The number of samples collected amounts to ca. 300, most of them taken from vegetation analyses. All samples will be incorporated in the Herbarium of the State University of Utrecht, Netherlands.

    Description: The present paper is the first of a series of regional revisions of the Old World Lindsaeoid ferns centering around a revision of the group in the Flora Malesiana area where the largest number of species occurs. In the few cases where modern revisions are already available the present author’s contribution will be limited to critical and additional notes; otherwise they will be in the nature of monographic treatments, although widespread species will, of course, as a rule not be described more than once. The botanically isolated position of New Caledonia is well-known, and most floristic phytogeographers agree in regarding it as a separate floristic region (e.g. Good, 1947; Van Balgooy, 1960). Endemism is high in the ferns as well as in the flowering plants, although the number of endemic fern genera is very small (Brownlie, 1965). In the absence of a comprehensive modern fern flora I am unable to quote any reliable figures. The last paper dealing with the New Caledonian fern flora as a whole by Fournier (1873) is nearly 100 years old. Later contributions were made notably by Copeland (1929b), Christensen (in: Däniker, 1932), and Guillaumin (1962- 1964). Christ (1910), on the basis of Fournier’s (1873) data, reported 259 species, 86 endemic, but stated that Fournier’s species concept was apparently too narrow (p. 234), which I can confirm for the Lindsaea group, as shown by the synonymy in the present paper. On the other hand, additional species have been found or distinguished since. A more important factor limiting our knowledge of endemism in the New Caledonian ferns (and other plants) is, I think, the poor state of knowledge of the Melanesian flora, particularly of the Solomon Islands. The exploration that is now in progress in this archipelago may be expected to furnish important additional data.

    Description: It is well known that the chromosome number of a plant may be a character of importance to taxonomy; it can often give a better insight with respect to the place of a taxon in the System. It is, therefore, particularly important to determine for any species the chromosome number of as many individuals from as many localities as possible. Publications of lists of documented chromosome numbers as presented by Love in the IOPB reports in Taxon are very valuable and so are lists of chromosome numbers of plants from more restricted areas (Greenland: Jörgensen et al., 1958; Iceland: Löve and Löve, 1956; the Netherlands: Gadella and Kliphuis, 1963; Poland: Skalinska, 1950, Skalinska et al., 1957, 1959, 1961; Sweden, Skåne: Lövkvist, 1962). These lists enable us to ascertain whether or not there are differences in chromosome numbers within a species and whether or not there is a relation with the geographical distribution or the ecological preference. Apart from the number, however, the size and shape of the chromosomes and, consequently, their ‘portrait’ may be of value. In the Angiospermae this character plays an important role almost exclusively in the Monocotyledones.

    Description: The flora of the southern Surinam savannas (not completely known but probably so for the greater part) consists of 314 species collected so far. Ten of these were not found in any other region, 6 belong to the southern Guianan element, 14 to the Guianan element, the rest have a wider distribution. Fourty of the species occur in this region on the northern limit of their area and 18 of these even reach their northernmost station here. Among the 290 species collected on savannas in central Amazonia 82 species were found also on the savannas of southern Surinam. Northern Surinam, with a total of 288 recorded savanna species, has 183 species in common with southern Surinam. This floristic contrast can be correlated for about half of the differentiating species with ecological or geographic factors. The geographic spectra of the two regions are greatly similar.

    Description: In this third report of this series concerning biosystematic studies of the Dutch halophilous species of Spergularia, the relation between the variation and the environment is discussed. In the case of S. media, a correlation between the occurrence of populations with a high representation of plants with unwinged and subalate seeds and the degree of extremity of the abiotic factors prevailing in the habitat seems to be manifest. In some cases overgrazing by sheep or cattle also results in a relatively high representation of such plants in the population, even if the abiotic factors are favourable. The possible causes of a selective advantage of winged seeds over exalate seeds in certain types of habitats (and vice versa) are discussed. The predominantly autogamous S. marina occurs in populations consisting of plants with unwinged seeds. However, one population was found containing plants with winged seeds; the possible ecological causes of this phenomenon are mentioned.

    Description: In the Netherlands the distinction of the species Spergularia media (L.) C. Presl (Syn.: S.marginata (DC.) Kittel) and Spergularia marina (L.) Grisebach (Syn.: S.salina J. et C. Presl) is not always easy. These taxonomical difficulties gave cause to investigate the variability of these two halophilous species. From a nomenclatorical study it appeared that S.media and S.marina are the legitimate names (Chapter I). The variability of both Spergularia-species has been studied by means of population samples (Chapter II). The seeds of S.media and S.marina vary from unwinged to broadly winged; however, the variation per plant is limited, the plants mostly producing in their proximal capsules either unwinged to rudimentary or narrowly winged, or only broadly winged seeds. These differences in the width of the seed wing are apparently genetically controlled. In general the winged seeds are larger than the unwinged seeds. The most important diagnostic characters of both Spergularia-species are (a) the number of stamens: in S.media (0-)10, in S.marina (0-)2-5 (-10) and (b) the diameter of the flower: in S.media (7-)10-12(-13) mm, in S.marina (4-)5-7(-8) mm Both species show a reduction of the androecium; the total number of stamens and staminodes of S.media is always 10, but when staminodes are present the diameter of the flower is smaller; flowers 7-8 mm in diam. always have a considerable number of staminodes. S.marina rarely has staminodes: if present there are at most only three of them. Other diagnostic characters are the length of the bracts and the position of the stigmas. In Chapter II the variability is correlated with the geographic distribution and the environment. The distribution of S.media on the outside of the dikes can be correlated with the salinity of M(ean) H(igh) W(ater). The limit of distribution upstream in the estuaries is found near the transition of Polyhalinicum to Mesohalinicum (see page 72). S.media is a differential species of the order Glauceto-Puccinellietalia. In some respects this species shows an independent behaviour in its relation to the other species of this order. S.media occurs in a zonation of vegetation in the Artemisietum maritimae and not in the Puccinellietum maritimae and vice versa. In sandy regions S.media is found in the zonation below Puccinellia maritima. Populations of S.media with a high frequency of plants producing unwinged seeds are found in open pioneer vegetation, on sandy soil in an extreme and unstable environment (see photo 2, page 81) or in intensively grazed vegetations (also on clayey soils). Populations of S.media composed of plants that produce exclusively winged seeds, are found in closed vegetation on clayey soil in a less extreme and more stable environment (see photo 1, page 81). In the population complex of S.media there is apparently an ecotypical differentiation. Populations composed of plants producing exclusively unwinged seeds do not occur in the Netherlands, the pressure of selection probably not being strong enough. On the isle of Römö (Denmark) and according to reports in the literature also elsewhere in Europe and North-Africa there are populations exclusively composed of plants with unwinged seeds. As the genetically controlled variability of the size of the seeds and the seed wing is largest in relative extreme and unstable environments, the variability decreases when the environment becomes less extreme and more stable. This also happens when the environment becomes very extreme. When population of extreme and less extreme environments are compared, the population density is higher, and the mean age of the individuals lower, in the first case. The distribution of S.marina on the outside of the dikes can be correlated with the salinity of M(ean) H(igh) W(ater). In the Mesohalinicum (see page 72) S. marina is found on the level of M.H.W., in the Polyhalinicum and Buhalinicum S.marina occurs at a higher level with regard to M.H.W. Upstream in the estuaries the limit of distribution is found mostly near the transition between Mesohalinicum and Oligohalinicum. S.marina is a differential species of the alliance Puccinellio-Spergularion. The species occurs in the subordinate associations with high presence. In one locality in the Netherlands, (see photo 3, page 110), namely in the eastern part of Terschelling, a population of S.marina is found that for the greater part is composed of plants producing exclusively broadly winged seeds in their proximal capsules. In general it can be concluded that incidental factors have a considerable influence on the variation pattern in the Netherlands as a result of the small size of the local populations, the scattered habitats and the obligatory autogamy. As regards dissemination, S.media and S.marina are polychorous, namely anemochorous, hydrochorous, zoochorous and anthropochorous (Chapter IV). Both Spergularia-species show a number of differences in floral structure and floral ecology (see page 124 e.v.). S.media is, dependent on the circumstances, allogamous or autogamous; S.marina is almost invariably autogamous, very rarely allogamous. Both species do not hybridise (Chapter IV). The diploid number of chromosomes of S.media is 18 and of S.marina 36 (Chapter V). In Chapter VI a taxonomic description of S.media and S.marina is given and a key of all the Spergularia-species native in the Netherlands. The final conclusions of the general discussion (Chapter VII) are that S.media and S.marina are clearly distinguishable on morphological, cytological and also ecological grounds. The species are reproductively isolated. Both species are very variable. In the population complex of S.media a great deal of ecotypical differentiation is found. The local populations of S.media are not reproductively isolated, and the same applies to the local populations of S.marina. As the variation is clinal no infraspecific taxa are described.

    Description: The anatomy of the mature wood of three species of the South American genus of woody climbers Dicranostyles Bth. is described and compared with that of the secondary wood of other genera of the Convolvulaceae. The stems are characterized by the occurrence of concentric rings of included phloem tissue. In most characters the three species are quite similar, except for the absence of rays over two cells wide in D. guianensis. Instead of these, aggregate rays occur at intervals between consecutive rings of included phloem. D. mildbraediana possesses fibre tracheids with next to the normal large bordered pits numerous very large irregular slits giving the impression of a helical sculpturing of the walls. From a comparison with other Convolvulaceous genera like Bonamia, Ipomoea, Maripa, Neuropeltis, and Prevostea¹ it appears that nearest to Dicranostyles in general appearance as well as in anatomical structure is the genus Maripa. The resemblance to Ipomoea seems only superficial. The relation between anatomical conformities of genera and their position in the various systems of subdivision of the family is discussed.

Each of those complexes shows some variation in its floristic composition caused by ecological and geographical factors. The water and mineral nutrient content of the soil are the two ecological master factors.

    Description: The variability of the principal differentiating characters of Spergularia marginata and S. salina was studied by means of analyses of population samples. Both species proved to be sharply definable in the Netherlands; no intermediates were found. In certain habitats a form of S. marginata occurs with exclusively unwinged seeds. It seems that S. salina, on the other hand, has a form with broadly winged seeds only. So far it was found in but a single Dutch station.

    Description: At least some of the species of the genus Caltha are polymorphic, showing not only a wide range of intraspecific morphological variation, but also considerable cytotaxonomic differentiation. A number of taxonomic problems are connected with this phenomenon. In a previous paper (Smit, 1967) a survey of the chromosome numbers of 46 Dutch populations was given. Two cytotypes of Caltha palustris were found, 2n = 32 and 2n = 56, respectively, with slight morphological differences and different ecological preferences.

    Description: It is often assumed that the delimitation and the subdivision of the various families which have been distinguished in the Angiosperms, do no longer offer serious difficulties. They would belong to those objects of study for which already long ago a fairly satisfactory solution was found. If we wish to be acquainted with this solution, the only thing we would have to do, would be to look up such works as Bentham and Hooker’s “Genera Plantarum” and Engler and Prantl’s “Natürliche Pflanzenfamilien”. Some improvements might still be desirable, but these would be of minor importance only. These assumptions, however, are to be regarded as dangerous illusions. That the very serious nature of the shortcomings found in the delimitation and subdivision of these families, especially of the larger ones, is so often overlooked, is apparently due to an attitude of mind which is observed in a comparatively large part of the taxonomists, viz. a lack of interest in the development of a truly natural classification. This is not incomprehensible. Most of them spend the major part of their time in the elaboration of floras covering areas of more or less limited extent, and they are but rarely aware of the fact that the knowledge of the families which is obtained in this way, remains necessarily incomplete. Moreover, in the elaboration of a flora the most essential point is the construction of serviceable keys to the species as well as to the groups of higher rank, not the exact delimitation of these groups: to the latter end usually more material is required than the compiler of a flora has at his disposition. However, we must not overlook the fact that a key, in order to be serviceable, need not reflect the degree of affinity between the units with which it is dealing; in reality, such keys are often entirely or almost entirely artificial, and this applies therefore also to classifications which are based on such keys. To illustrate this, I will discuss here some of the characters by the aid of which in the Rubiaceae very suitable keys to the genera have been constructed, but which when they subsequently were used for the elaboration of a classification, led to entirely unsatisfactory results.

    Description: The Brinckheuvel Nature Reserve includes the most characteristic part of the geomorphological Sabanpasi (or Subgreywacke) landscape (see fig. 4), formed by low, elongate, parallel, gently sloping ridges. The centre of each ridge is crowned by a narrow rib (gravel rib) (see fig. 5). The gravel ribs are in general formed by residual soils of sandy loam covered with a thin layer of quartzite material. The flanks of the ridges are occupied by sandy colluvial soils separated by a layer of gravel from the residual subsoil. At the bases of these flanks there is alluvial soil (see fig. 5 and 9). Generally the residual and colluvial soils bear savanna vegetation, the alluvial soils bear xerophytic wood and mesophytic forest. In the savanna vegetation on the ribs and the flanks of the ridges twelve plant communities can be distinguished (see table I and II). The residual soils are hardly permeable; the colluvial soils, on the other hand, absorb rainwater quickly and soon dry up again. In the Nature Reserve there are three hills; Brinck Hill, Klaiber Hill and Lobles Hill. They rise about 30 m above the level of the vicinity and consist of unweathered subgreywacke rock; their tops are flat and have a cover of 6 m of very permeable, white sand (see fig. 6). In the places where the vegetation was burned in the last few years there is now a savanna vegetation in which fourteen plant communities can be distinguished (see table I and II). The rest of the tops of the hills is covered with xerophytic wood. The rainwater quickly seeps through the white sand cap to the unweathered subgreywacke, runs off sideways, and reappears at the foot of the cap (the so-called source level). On the greater part of the slopes of the hills the subgreywacke crops out, with little gullies and furrows that are filled with erosion material. Ca. 245 species of plants were collected on the savannas of the Brinckheuvel Nature Reserve. Except in places where the influence of fire was noticeable, the presence of a more or less impermeable soil layer at shallow depth is doubtless responsible for the existence of the savannas of the Nature Reserve. This layer makes it possible that the overlying permeable mass is alternately wet and dry, depending on the season. The degree to which this happens depends not only on the thickness of this permeable topsoil but also on the inclination of the surface. This may be illustrated by the following (see fig. 10): 1. Xerophytic forest is found on white sand caps and slopes of the three hills and on very high gravel ribs. In such places the rainwater disappears rapidly, either the soil is well drained (white sand caps), or because most of the water runs off on the surface owing to the sloping of the ground. The soil is never extremely wet. 2. Savanna scrub is found on less high residual ribs and on gently sloping land with a thick permeable topsoil. In both cases the soil can take up more water and hold it longer. The contrast between wet and dry is greater. 3. Savanna hushes and open vegetations are found on the parts with a more level and thin topsoil of permeable material. The topsoil is soon saturated with rainwater that can not or hardly drain off, but dries up relatively soon. The contrast between wet and dry is therefore even greater. 4. Exclusively open vegetations, finally, are found on flat savanna parts with a few cm deep soil situated on uneroded rock, e.g. at the source level of the three hills, beside or near great rock flats and on level residual ground covered with gravel. Here we find the greatest contrast between wet and dry. All this illustrates the fact that in the Sabanpasi savanna area the hydrology of the soil is one of the principal habitat factors. Therefore, more attention should be paid to this factor by a next investigation in the Brinckheuvel Nature Reserve.

    Description: The delimitation of genera in the Campanulaceae, especially in the subtribe Campanulinae, meets with serious difficulties. Linnaeus (1753, 1754) distinguished 3 genera: Campanula, Phyteuma, and Trachelium. In A. de Candolle’s (1830) monograph of the family 334 species were recognized, classed in 21 genera. Species of 12 of these genera had formerly been included in Campanula. Yet the genus Campanula still appears too inclusive, and the delimitation of some other genera is open to dispute. Not only the delimitation of genera presents serious difficulties, there is also no common opinion on the arrangement of the genera in tribes. The more important systems are those of Schönland (in Engler and Prantl, 1894) and of Fedorov (1957). Schönland arrived at the following subdivision of the Gampanuloideae: Campanuleae, Pentaphragmeae, and Sphenocleae. In the present paper only the first of these tribes will be taken into consideration. The tribe Campanuleae was divided by Schönland into three subtribes: Campanulinae (Adenophora, Canarina, Heterocodon, Mindium (= Michauxia), Ostrowskia, Symphyandra, Phyteuma, Trachelium, Legousia, Campanula, Perocarpa), Wahlenberginae (Codonopsis, Edraianthus, Jasione, Wahlenbergia and 13 other genera), and Platycodinae (Platycodon, Microcodon, Musschia). Fedorov (l.c.) divided the subfamily Campanuloideae into 8 tribes: I. Campanuleae (Campanula, Symphyandra, Brachycodon, Adenophora, Popoviocodonia, Astrocodon), II. Peracarpeae (Perocarpa), III. Ostrowskieae (Ostrowskia), IV. Michauxieae (Michauxia), V. Phyteumateae (Phyteuma, Asyneuma, Sergia, Cryptocodon, Cylindrocarpa, Legousia), VI. Wahlenbergieae (Wahlenbergia, Codonopsis, Platycodon), VII. Edraiantheae (Edraianthus), VIII. Jasioneae (Jasione).

    Description: This study was undertaken in 1963 at the suggestion of Prof. Dr. J. Lanjouw. As the genus Convolvulus is so large that a revision of all its species would have taken too much time, and as a revision of the African ones alone would not have been interesting because these species do not form a natural group, it was decided to choose a middle way, and to take into consideration also the species occurring in the adjoining countries. This was all the more Indicated as the Convolvulus species of the area which includes besides the Mediterranean region also the area extending eastwards of the latter to the western border of Afghanistan, i. e. such countries as Iraq and Iran, show many signs of affinity. During our study of the species occurring in these parts, it was realized that it would be desirable to consider also those occurring in Afghanistan and Turkmeniskaya and further to the west in the Caucasus, Armenia and a part of the area surrounding the Black Sea. The Canary and Madeira Isles were also included, as they are close to the North African part of this region and as these islands moreover are interesting because they show a high degree of endemism and because some of the Convolvulus species occurring here were regarded by some authors as sufficiently distinct from those found elsewhere to be referred to a genus of their own, a genus for which the name Rhodorrhiza was proposed. The genus Convolvulus was introduced by Linnaeus (1753). In 1789 it was revised by Desrousseaux, who described 107 species under the heading “Liseron”; he divided the genus into two subdivisions, viz. 1° “peduncles with solitary flowers” and 2° “peduncles with numerous flowers”; in the delimitation of the genus he followed Linnaeus.

    Description: Op de 28ste september van het jaar 1859 sprak de toen juist aan deze Universiteit benoemde hoogleraar Miquel zijn ‘inwijdingsrede’ uit „over het tegenwoordig standpunt der plantenkunde en haar verband met andere wetenschappen”. Miquel was op het moment van het uitspreken van zijn rede een algemeen bekend botanicus, maar toch wel in de eerste plaats een plantensystematicus, en zijn rede was daarom in hoofdzaak een bespiegeling over de positie van de plantensystematiek te midden van verwante disciplines. Zij bevatte bovendien een aantal min of meer theoretische beschouwingen over de grondslagen van de plantensystematiek. Nu is het jaar 1859 niet de geschiedenis van de biologie ingegaan als het jaar van Miquel, maar zoals u allen uiteraard bekend is, als dat van de publicatie van Darwin’s On the origin of species op de 24ste november, nauwelijks twee maanden dus na Miquel’s rede. Door Darwin’s eerdere geschriften, alsmede ook door voorzichtig tastende maar soms ook wel wild fantaserende eerdere theorieën, was het terrein als het ware rijp voor de grote revolutie in het biologische denken, voor de Umwertung aller Werte ook in de plantensystematiek. Het algemene biologische denkpatroon van Miquel en van de meeste van zijn collega’s echter was nog overwegend dat van de oude orde. De samenvatting die Miquel op 28 september uitsprak kan gezien worden als de afronding van een tijdvak. Het is verleidelijk op dit moment een, uiteraard zeer summier, overzicht over de staat van theorie en praktijk van de plantensystematiek in het jaar 1966 te plaatsen tegen de achtergrond van Miquel’s samenvatting op deze zelfde plaats gegeven in dat voor de biologie zo belangrijke jaar 1859. In dat jaar was het al evenmin als nu meer vanzelfsprekend dat iedere beoefenaar van de natuurwetenschap bij zijn vroege opleiding een goede training ontvangen had in de beginselen van logica en filosofie. Deze goede gewoonte behoefde echt niet de ontwikkeling van het voor de natuuronderzoeker zo essentiële empirisme in de weg te staan – integendeel! Op het vasteland van West-Europa echter, was ze al tijdens de Franse revolutie verdwenen. Toch was, vooral in de plantensystematiek, enig begrip op deze gebieden niet geheel overbodig als men zich ten minste rekenschap wilde geven van de theorie van zijn eigen vak. Vooral de Aristotelische logica beheerste de systematiek van de levende wezens tot diep in de negentiende eeuw. Dit wil niet zeggen dat de systematiek, of deze nu door zoölogen of botanici beoefend werd, slaafs een a-prioristisch systeem volgde en blind was voor de door directe waarneming verkregen feiten. De ordening van begrippen, theorieën en axiomata, die het systematische gedeelte van elke wetenschap kenmerkt, was echter veelal nog beheerst door de grondbeginselen van de Aristotelische logica (vgl. bijv. Cain 1958, 1959). De biologische systematiek omvat de ordening van op grond van de studie van organismen gevormde groepsbegrippen; taxa zouden we nu zeggen. De systematiek van vóór 1859 was in hoofdzaak gebaseerd op vormovereenkomsten en ging uit van de constantie van de te ordenen veelvuldigheid. De Aristotelische logica kende geen tijdsbegrip. Basaal was de constatering dat er in de menigvuldigheid leemten optraden die meer of minder groot waren en die daardoor het opstellen van hiërarchisch gerangschikte groepen mogelijk maakten. In de logica had men als ordeningsbegrippen genera en species. Hierbij waren genera synthetische en species analytische eenheden. Deze termen waren oorspronkelijk relatief: een genus kon steeds weer zelf als species deel uitmaken van een hogere categorie die dan weer genus genoemd werd. Sinds Ray en Tournefort echter gebruikte men in de biologie de begrippen genus en species ter aanduiding van categorieën in een zeer bepaalde rang. Bij dit systematisch onderzoek was er kennelijk geen behoefte rekening te houden met de specifieke eigenaardigheden van levende wezens. Als men wilde definiëren wat men onder een soort verstond dan ging men wel zover te zeggen dat soorten groepen individuen waren die gelijke nakomelingen kregen. In de praktijk van de soortsomgrenzingen was er echter vrijwel nooit sprake van het experimenteel nagaan of de tot een soort gerekende exemplaren nu ook inderdaad zulk een voortplantingsgroep vormden. De systematiek was geheel gebaseerd op vormverwantschap. Wel ziet men door de gehele biologie een streven de soorten zo goed mogelijk te definiëren; tot een algemeen geldige definitie kwam men echter niet en is men ook niet gekomen. Dit vraagstuk van een algemeen te aanvaarden soortsbegrip is in feite een schijnprobleem. Het soortsbegrip dat men toepast wordt bepaald door de methode die men volgt, bijvoorbeeld formeel, experimenteel of historisch. In de praktijk van de systematiek doen zich vele combinaties van methodieken voor die dikwijls weer eigen soortsbegrippen met zich mee brengen.

    Description: In 1888 K. Schumann described a new, monotypic genus of the Passifloraceae from Papua, Hollrungia aurantioides K. Sch. (Bot. Jahrb. 9: 212). Its generic distinction was largely ascribed to the peculiar sessile, cap-shaped, undivided stigma (“tellerformige Narbe”) and a 3-angular ovary. Harms, who elaborated Passifloraceae for the first and second editions of the “Pflanzenfamilien”, provided a figure of a section of the flower and a cross-section of the ovary (1.c. 3, 6a: 86, fig. 25 E-F. 1893, and 21: 495, fig. 218 E-F. 1925), maintaining Schumann’s observation that Hollrungia possesses an androgynophore which brings it alongside Passiflora, but differing from that genus by the undivided cap-shaped stigma. This kind of stigma is rare in the Passifloraceae and Harms recorded it in the family only for two other, monotypic African genera Crossostemma and Schlechterina.

    Description: Artificial hybridization experiments were carried out between two species-pairs in the genus Campanula, viz. between C. persicifolia and C. latiloba, and between C. alliariifolia and C. ochroleuca. The hybrid between C. persicifolia and C. latiloba is completely sterile. For this reason the treatment as separate species of these closely allied taxa is justified. The hybrid between C. alliariifolia and C. ochroleuca. on the other hand, is completely fertile. Therefore, it is advisable to regard C. ochroleuca and C. alliariifolia as conspecific, as was previously done by Kem. Nathadze.

    Description: In my work for the Index Muscorum it became apparent that dating problems existed for publications of the years 1825-1827, which were important for the nomenclature of Musci. The article by Arnott, Nouvelle disposition méthodique des espèces de mousses, was indicated from 1825 in some sources, but the copy of the periodical consulted had the title—date 1827 and the fascicle conderned probably was issued in 1826, Bridel, Bryologia universa, had the internal date 16 Dec. 1826 in the preface, usually bound with vol.1 the year 1826 for this volume, therefore, could be doubted. Moreover a supplement to the same volume was apparently published later than the main text, but the date 1827, assigned to this part in the preparation of Index Muscorum, was not fully confirmed. Some of the 11 parts of Schwaegrichen, Species Muscorum ... Supplementum, had to be dated with more precision, in connection with other works, th than was possible during the work for the Index Muscorum. Within the framework of the project Bibliographic Huntiana of the Hunt Botanical Library, Pittsburgh, Pa., it was possible to select a chapter of botanical bibliography, and the bryological publications of these three years were chosen with the literature related thereto. An effort was made to trace every book containing names of Musci. Articles in periodicals were not checked as thoroughly as the books. To bridge the gap between 1825 and 1821, the last year studied by Dr. Sayre in her Dates of publications treating Musci ... , bryological publications of the years 1822-1824 were studied too, but no effort was made to treat this period exhaustively. The publications included in this thesis are described according to the method of descriptive bibliography, as developed by W.W. Greg, F. Bowers, and for botanical books by Allan Stevenson. This method is adapted to the problems of the books of the period, by omitting the description of some features (binding, type-font) and by using page references in the descriptions of the contents instead of signature references. Some refinements in the method are proposed and applied. A new key for determination of books of handmade paper, especially laid paper, is included, Information concerning the dates of publication was derived from the references to reviews and announcements in contemporaneous periodicals, collected by a team of workers of the Hunt Botanical Library; I checked the original sources in many cases which might be critical. Moreover I studied several manuscript collections in botanical libraries and in archives. Completeness in these two fields, reviews and manuscripts, of course, is impossible, but some important sources remained untapped because of time restrictions. The result is the first analytical bibliography of all publications on a plant group of a certain period, at least to my knowledge. A considerable number of dates of publication are given with more precision than was the case up to now. Some of the important solutions to special problems or new points which came to light are enumerated below. 1. The article of Arnott was published in no less than 5 variants. The first one certainly is the quarto separate, which has the title-date 1825. My research made it probable that this was issued in January 1826. The later variants may be of importance because of indirect references to Schwaegrichen and Gaudichaud. 2. The two volumes of Bridel: Bryologia universa, were indeed published in 1826 and 1827, as the titles indicate; however, the supplement to vol.1 and the preliminaries were published together with vol.2. 3. The several parts of Schwaegrichen’s supplements are placed in the chronological order with the other important publications. For some parts, however, more accurate dates would be welcome. 4. The relative dates of Greville: Flora Edinensis, and the relevant fascicle of his Scottish cryptogamic flora were better established than those used in the Index Muscorum. 5. The contents, of the fascicles of a number of books and periodicals were determined, mainly with the help of internal bibliographical evidence. These were in several cases not known to the last details, e.g. Hooker: Musci exotici and Exotic flora. Off-sets of fascicle-titles in a particular copy of the latter work were helpful in establishing the breaks and dates of some fascicles. 6. Some publications were found, of which the new names of Musci were overlooked in the bryological literature (Cambessèdes, Chevallier). 7. The first color prints of mosses, to my knowledge, are indicated: of protonema in T.F.L. Nees von Esenbeck, 1824, and of complete plants in Sommerfelt, 1826, and Chevallier, 1826. 8. Of several books cancellantia are described which were not yet indicated before, including some in the starting-point book, Hedwig: Species Muscorum frondosorum. 9. Wove paper, originally used for expensive paper states of books, apparently became available in larger quantities and at relatively lower prices in the period treated, since several books show a shift from laid to wove paper. Machine-made paper was not yet often used for books; I only saw this paper type with certainty in the Transactions of the Linnean Society [London] of 1827 (see Greville n.9). As a general result of this research I can discuss the development of bryology in the first three decades of the 19th century, stressing the application of the natural classification to bryophytes, and the diverse opinions on the life cycle of mosses.

    Description: The oak mildew invaded Western Europa in the years 1908 and 1909. Since then this parasite, Microsphaera alphitoides Griff. & Maubl. (syn. M. quercina (Schw.) Burr.) has occurred regularly in the Netherlands on oak seedlings and oak coppice, mainly Quercus pedunculata Ehr. (syn. Q. robur L. ). After the appearance of the fungus its identity and also its mode of hibernation has been amply discussed. Perithecia with ascospores were discovered by Arnaud and Foëx (1912) in France. In the Netherlands perithecia were only occasionally observed, as their occurrence seems to depend on weather conditions during the summer months (Hartsuyker, 1939). Besides ascospores, if present, chlamydospores on old infected leaves described by Ferraris (1909) might be a source of infection of young leaves in spring (Petri, 1923). However, these observations were not confirmed by other investigators. Neger (1911), Peglion (1911), and somewhat later also Van Poeteren (1912) observed hibernation of the mildew in infested buds from which malformed shoots developed in spring, stem and leaves being covered with mycelium and conidia. Woodward et al. (1929) described the way the mildew spreads: conidia from these shoots infect young healthy leaves in the neighbourhood, on which circular colonies develop. The growth of these white patches stops rather soon, probably owing to thickening of the cuticle of the ageing leaves. As has been noted by Ditu et al. (1964) leaves are severely attacked up to the age of 20 days. A second outbreak may occur on the newly developed Lammas shoots. Van Poeteren (1918) gave a clear description of the two periods of spread.

    Description: During the last world war the town of Caen was almost completely destroyed. The valuable collections of the Caen herbarium (CN) were evacuated and were thus saved. It is now twenty years after the war. The town of Caen has been beautifully rebuilt and the newly erected buildings of the university are very impressive. This university, founded in 1432, is now said to be not only the oldest but at the same time the most modern in France. Although the herbarium is now in a modern building, this does not mean that it is managed in a modern way.

    Description: We deeply regret to have lost three ardent supporters since the last bulletin appeared. Among them the nestor of Malesian botanists, Mr. I. H. Burkill, who passed away at the age of 94, a gentle scholar whom we had the privilege to meet on several occasions and with whom we had a fairly lively correspondence. Originally a collaborator of Sir George Watt on Economic Products of India, explorer of the Abor Expedition, Assam, later director of the Singapore Botanic Gardens, he had a wonderful knowledge of and intense interest in the relations between man and plants. This was probably the reason that he got deeply interested in the botany of the yam family, of which he became a specialist, taxonomical, ecological, morphological and anatomical. He had also a deep interest in the relations between plants and animals, pollination, seed dispersal, subjects now much neglected because of the modern specialisation of biologists. His classic Dictionary of the Economic Products of the Malay Peninsula is in course of a second edition and his learned essays on the History of Indian Botany is expected to appear in book form.

    Description: Taiwan herbaceous flora (see Fl.Mal.Bull. 22, p. 1562). In 1968 Prof. Hui-Lin Li spent a considerable time in Taiwan discussing this project with Taiwan botanists and authorities. An agreement was finally reached among those who are to be actively participating and a plan of procedure and a budget were prepared. These were presented to the Science Commission of the Central Government for approval. No action has yet been taken (Dec. 1968). Prof. Li will spend half a year sabbatical leave at the Smithsonian for this work. Musci of Taiwan. During two summers of 1967 and 1968 Dr. Ching-Chang Chuang collected Musci in Formosa and is working on these in the University of Vancouver, Canada.

    Description: For the Javanese mountain plants, all growing on separated volcanic peaks, it has been found before that to grow on a mountain there is for each species a critical altitude necessary of the total height (elevation) of the peak or mountaincomplex. This is best elucidated by an example: Albizia lophantha (montana) is found in Java from 1100-3100 m, but only on mountains of which the summit reaches at least 2500 m altitude. This means that it is not found on mountains of 2400 m summit height or lower, although it may descend on mountains of 2500 m summit height and higher as low down as 1100 m altitude. The elevation effect is calculated in this case as 2500 minus 1100 = 1400 m.

    Description: Here is given a sample of a new sort of identification key, recently developed by Dr. P. W. Leenhouts of the Rijksherbarium. Having to sort many specimens of Sapindaceae into genera, he became dissatisfied with the common dichotomous key, which too often does not work when the material is not complete. When he had extracted the existing descriptions, tabulated the characters, and written them up horizontally, with the names in code, he found not only that in a given space it contained far more information than does a dichotomous key, but also that it worked far better. He then proceeded to devise a synoptic key to the Malesian species of Santiria The numbering of the species is the same as that in the Flora Malesiana revision (I, 5: 229), namely: 1 = tomentosa, 2 = mollis, 3 = grandiflora, 4 = laevigata, 5 = oblongifolia, 6 = ridleyi, 7 = conferta, (8 has been transferred to Dacryodes), 9 = apiculata, 10 = megaphylla, 11 = griffithii, 12 = rubiginosa.

    Description: In Flores, Timor, and some other of the Lesser Sunda Islands at least two distinct species of Eucalyptus occur, E. alba (vern. hoë) in the lowland and low hills and a second species (vern. anpupu) in the hills and mountains. A century ago Blume described some eucalypts from the Leyden Herbarium based on duplicates he had received from the Paris Herbarium, collector unknown. Two sheets he assigned to E. obliqua L’Hérit. localizing them in Tasmania, another one which he called E. decaisneana Bl. he assigned to Timor. The latter has in the past sometimes been associated with the mountain species ’anpupu’, but Dr. Blake, in 1951, came to the conclusion that Blume’s type of E. decaisneana must belong to E. obliqua and cannot hail from Timor, but must be localized either in SE. Australia or in Tasmania. ’Anpupu’ is a still undescribed new species which we hope will be named by Dr. Blake. To me it seems logical that this specimen is also from Tasmania.
