Description: A. DE CANDOLLE’s (1830) treatment of the genus Campanula lists 137 species. Many new species were described since, so that the total number of species should be estimated to be at least twice that number. A new monograph of the genus is, therefore, highly desirable (CLIFFORD CROOK, 1951). Any classification into subgenera and sections, based on herbarium studies, is bound to meet considerable difficulties on account of the great uniformity among many floral characters of the various species. Cytological information may prove very valuable in order to arrive at a modern classification of the species within the genus.

Description: Cytological studies on the Rubiaceae with special references to the genus Galium have been done by HOMEYER (1936) and FAGERLIND (1937). EHRENDORFER (1949, 1954, 1955, 1956) described the phylogeny of the section Leptogalium. More detailed cytological and cytotaxonomical investigations appeared by HANCOCK (1942) (Galium palustre L., Galium debile Desv. and Galium uliginosum L.), CLAPHAM (1949) ( Galium palustre L.), EHRENDORFER (1949, 1953) (Galium pumilum Murr.) 1955 (Galium rubrum L. and Galium pusillum L.) and of Galium boreale L. by Löve and Löve (1954) and more recently by RAHN (1961). FAGERLIND (1937) and, previous to him, HOMEYER (1936) determined the chromosome numbers of many Galium species. Later investigations by EHRENDORFER (1949, 1955, 1956, 1961), LÖVE and LÖVE (1954, 1956), PIOTROWICZ (1958), POUQUES (1949), RAHN (1960, 1961) and REESE (1957) confirmed and supplemented this list of chromosome numbers. Many investigators have paid attention to the genus Galium. However, their studies have concerned only with some critical species or groups. Many taxonomical problems remain concerning the genus. SCHUMANN (1891) in ENGLER and PRANTL „Die Natürlichen Pflanzenfamilien” divided the genus in 14 sections which are very distinct morphologically. However, within these sections it is often very difficult to define exactly the morphological differences between the species.

Description: This is the second paper dealing with Myxomycetes collected by me in the Netherlands, mostly in the neighbourhood of Doorwerth. Specimens of the species dealt with are preserved either in my private collection or in that of the Botanical Museum and Herbarium of the State University, Utrecht (in the last named case the numbers are followed by a “U”), or in both.

Description: In the present study pollen morphology of the Euphorbeaceae is treated as an additional character in taxonomy. Besides the greater part of the genera occurring in the system of PAX and K. HOFFMANN (1931), most of the genera published after 1931 are studied. The pollen grains have been described with the aid of a terminology as simple as possible. In principle the terminology of IVERSEN and TROELS-SMITH has been followed, although in addition, many improvements of ERDTMAN have been used. One of the simplifications is the rejection of POTONIÉ’s term sculpture. All elements occurring on the endexine are called structure elements; all structure elements together form the structure of a pollen grain. For the sake of consequence endexine apertures and extexine apertures are discussed separately. Different pollen grains are placed in different pollen types. If the differences are of minor importance, the pollen grains are placed in subtypes. Several types can have some characters in common. To express the correspondences, these types are assembled in configurations. As the pollen types in Phyllanthoideae and Crotonoideae differ distinctly, the division of the Euphorbiaceae in these subfamilies is maintained in the discussion of the results. The Phyllanthodieae can be separated in three large groups of pollen types ( Antidesma configuration, Amanoa configuration and Aristogeitonia configuration), which agrees with the grouping of PAX in 1924. The remaining small configurations belong in taxonomic respect to the genera of the Antidesma configuration. In the Crotonoideae many genera possess pollen grains with a croton-pattern. These genera should be treated as a single group. Besides this natural group, the Plukenetiinae possess pollen grains which are clearly distinguished from other genera in the Crotonoideae. Pollen grains of Omphalea are similar to those in the Plukenetia configuration. This pollen-morphological result agrees with the opinion of CROIZAT. The remaining pollen grains in the Crotonoideae are less easy to differentiate in groups. One of the largest configurations is the Mallotus configuration, which includes most genera of the Acalypheae and several genera or other tribes. The Hippomane configuration is another large one. This configuration comprises the tribes Hippomaneae and Euphorbieae. The pollen grains of both tribes are very similar. The genus Pachystroma is pollen-morphologically as well as taxonomically related to the tribe Hippomaneae. Pera, treated as a separate tribe by PAX and K. HOFFMANN, is related by its pollen grains to some genera in the Acalypheae. Dalechampia is habitually related to the genera in the Plukenetiinae. Pollenmorphological data, however, do not support this relation. The pollen grains of Dalechampia are not similar to any other pollen type. The morphology of the pollen grains of the Stenolobeae is in agreement with the opinion of PAX, that any separation of these Australian genera is an artificial one.

Description: This series of two or more volumes starts to be published in the summer of 1962; the page proofs of the first volume, which was sent to the press in May 1960, were received by Dr. E. Quisumbing at Manila where the volume is being printed, in March; its publication can be expected by July 1962. The series ”Pacific Plant Areas” means to give all that is already known about distribution of taxa of generic and lower level which centre round the Pacific Ocean, and also to add to our knowledge by giving new maps which have been carefully prepared by specialists. Hence the series consists of a bibliographic part and a cartographic part, preceded by an explanatory introduction. Volume I is mainly bibliographic, containing about 3200 references to maps and 26 newly prepared maps; volume II will be mainly cartographic, containing about 124 newly prepared maps, and will hopely be ready for the press by the end of 1962.

Description: Dr. J.A.R. Anderson, Kuching, will go on leave in October 1962. Mr P.S. Ashton, Cambridge (U.K.), has accepted the post of Forest Botanist at kuching, Sarawak, and will in September 1962 proceed to Borneo.

Description: For the pollination of their flowers, plants of the genus Ficus are absolutely dependent upon the activity of small insects, the ”fig wasps” (Hymenoptera Chalcidoidea, family Agaonidae). Consequently, no account of Ficus can be exhaustive without considering the entomological data. On the other hand, the fig wasps can only develop in the gall flowers of the fig receptacle. Consequently again, in the evaluation of the data on fig wasps, great stress should be laid on the botanical evidence. These statements may serve as ample justification for the appearance of an entomologists’ notes in this botanical bulletin. Since 1960 I am working through a large collection of Indo-malayan and Papuan fig wasps, mainly consisting of the collection made by Dr. J. van der Vecht at Bogor, and material sent by Dr. E.J.H. Corner from various parts of Malaya, Indonesia, Papua, and Melanesia. As the study of the fig wasps is still in its analytical stage, progress is slow, but the results are promising.

Description: Balan Menon, P.K.: Taxonomic value of wood anatomy seen through Malayan woods. The Malayan Forester 24 (1961) 290- 301. Mr Menon, who is a wood technologist at the Forest Research Institute, Kepong, Malaya, presented this paper at the Hawaii Congress. In it, he gives a series of classifications of Malayan woods on the basis of anatomical features which can be seen by a hand-lens, he distinguishes 18 classes, notably woods with: ring-porous structure, exclusively solitary pores, multiple vessel-perforation, vestured (vessel) pits, scalariform intervessel pits, ripple marks, broad rays, uniseriate rays, septate fibres, distinctly bordered fibre pits, tanniferous tribes, latex tribes, horizontal canals, vertical canals, included phloem, mucilage or oil cells, silica inclusion, raphides.

Description: Mr C. Jeffrey of the Kew herbarium, who works on Cucurbitaceae, has been to the Seychelles for botanical collecting and exploration, his letter of Jan. 20, 1962 is interesting enough to quote the following passage from: ”You may be interested in a few impressions of the Seychelles flora, discounting introduced naturalized species, which now I fear cover most of the islands, I gain the impression that here we have a number of long-isolated and endemic species (perhaps some may prove subspecies?) of mixed African, Mascarene, and SE. Asian affinities, and mostly confined to higher ground on the larger islands, together with a number of indigenous non-endemic species which formed most of the original lowland vegetation, but some of which also occur in the higher parts, which are mostly (but not all) otherwise SE. Asian to Malaysian in distribution (the others are mostly Afro-Mascarene) or palaeotropical.

Description: Ample collections preserved at Uppsala under the name Hydnum versipelle and two exsiccata of Sarcodon laevigatus were examined and compared with the original descriptions. The material of Hydnum versipelle is shown to be heterogeneous, comprising three collections belonging to Sarcodon amarescens, and ten collections of a species which has the main characters of Sarcodon laevigatus. The few differences observed are attributed to differences of a chemical nature, and Hydnum versipelle is formally reduced to the synonymy of Sarcodon laevigatus.

Description: Among the new material which was examined by me after the completion of the revision of the genus Pittosporum for the Flora Malesiana (vol. I, 5, 1957) and additions in Nova Guinea n.s., 9, 1958, 339, the following is worth mentioning: Pittosporum pentandrum (Blanco) Merr. NORTH BORNEO. Ranau Distr., Bukit Ampuan, alt. 1500 m, Meijer SAN 20289, in primary forest on hill side ridge. Note. This is the first record from Borneo; otherwise known from Formosa, the Philippine Islands, and N. Celebes. Pittosporum pullifolium Burkill. WEST NEW GUINEA. Koebre Mts, Anggi Lakes, alt. 2300 m, Sleumer & Vink BW 14148, shrub 4 m, on forest edge, rather scarce, fruit green. Note. A specimen with young fruits on infructescences which are placed axaillary along the twigs, instead of being terminal.

Description: The family of Syrphid flies (“Hover flies” or “Flower flies”) is richly represented in the Neotropical region. FLUKE’S Catalogue of Neotropical Syrphidae, finished in September 1953, records 107 genera and 1,507 species, exclusive of 100 “species incertae sedis.” (In actual fact, 1,508 species are enumerated, but Baccha picta Wiedemann (FLUKE, p. 259) is an Ethiopian species.) The large genera Volucella with 274 species, Baccha with 269 species, Mesograpta with 130 species, and Eristalis with 106 species, seem to have had their greatest opportunity of development in this region. However, some of the names will probably prove to be synonyms, since the descriptions by earlier authors are often too short and insufficient to enable a species to be recognized with certainty. As a rule, the species described by recent authors are quite recognizable. Up to a few years ago the number of Syrphids described or known from Suriname was very small. Moreover, one of them, Volucella ardua Wiedemann, proved to be synonymous with Volucella tympanitis Fabricius, as stated by CURRAN, who studied WIEDEMANN’S type specimens. Of course, the number of the species taken on occasion in Suriname is somewhat larger; but, as far as is known, no enumeration has ever been published.

Description: Von 14 Taumelkäfer-Arten, die bislang für Guiana nachgewiesen waren, kannte man aus Suriname lediglich 2. Dank der Sammeltätigkeit der Naturwissenschaftlichen Suriname Expedition 1949 in den Nassau Gebergte erhöhen sich diese Zahlen um 3 neue Arten und 2 Unterarten, die hierunter beschrieben werden, auf 19 bezw. 7. Auch diese Ziffern erscheinen noch sehr niedrig angesichts der günstigen Lebensbedingungen, die den Taumelkäfern in diesem tropischen, von zahlreichen Bächen und Flüssen verschiedener Grösse und Charakters bewässerten Bergland geboten sind. Zweifellos wird in Zukunft eine gründliche Erforschung der verschiedenen Fluss-Systeme in verschiedenen Höhenlagen die Gyriniden-Fauna von Guiana um zahlreiche Arten bereichern. Meine vorliegende Arbeit behandelt nicht nur die in den 3 Guiana’s (Suriname, Französisch- und Britisch-Guiana) vorkommenden Gyriniden, es war vielmehr notwendig, auch den südöstlich anschliessenden Teil Brasiliens einzubeziehen, der seiner Natur nach dazu gehört, sowie 2 Arten, die am Mt. Roraima auf venezolanischem Gebiet entdeckt wurden, da für sie die Überschreitung der nahen Grenze von Britisch Guiana sicher kein Hindernis darstellt.

Description: This publication represents a continuation of a previous article on the Caribbean Vertiginidae (this series, Vol. X, 1960, No. 41), and it will follow the same arrangement as the former. This will not only add to the uniformity of the series, it will, furthermore, make it simpler to compile individual faunal lists from any locality situated within the region treated here. Yet another continuation will follow this article, in which some smaller families with their representatives in the Caribbean region will be listed. The photographs (Plates X E and XI I excepted) were again taken by Dr. P. WAGENAAR HUMMELINCK, with the technical assistance of Mr. H. VAN KOOTEN, at the Zoological Laboratory of the State University, Utrecht.

Description: The geology of the map sheets 1:50.000, 1 Garonne and 2 Salat of the Geological map of the Central Pyrenees is described. The stratigraphic sequence consists of Paleozoic rocks from the Cambro-Ordovician to the Carboniferous, and of Mesozoic rocks from the Trias up to the Tertiary. Hercynian and Alpine orogenies have acted on this intercontinental mountain chain. The Hercynian orogeny is accompanied by epi-to cata-zonal metamorphism in which several successive stages can be recognized. The Alpine orogenesis consists also of successive stages of which the Pre-Cenomanian one has been accompanied by basic rock intrusion and a particular kind of metamorphism. In the structure presented on these sheets a stretch of the axial zone is represented and a part of the external zone containing six of the satellite massifs, the two units separated from one another by the north Pyrenean fault zone.

Description: In the present series of papers the results of two different field trips to the West Indies are coordinated. Each paper, dealing with a convenient taxonomic group, will be numbered separately. The sequence of the taxonomic units is arbitrary. Part of the material on which the results are based was collected by J.H.S. during a five months’ stay (October 1958-February 1959) in the Dutch West Indies (or Netherlands Antilles, as they are more officially called), which was made possible by a grant from the Netherlands Foundation for the Advancement of Research in Surinam and the Netherlands Antilles (WOSUNA), Amsterdam. The greater part of the time was spent at the Caribbean Marine Biological Institute, Piscadera Bay, Curaçao, although short visits to the other islands of the Netherlands Antilles, viz. Aruba, Bonaire, St. Martin, St. Eustatius and Saba, have to a certain degree supplemented the results obtained in Curaçao.

Description: The chromosome numbers of some of the annual species of the genus Trifolium occurring in the Netherlands were investigated. In the summer of 1959 seeds were collected in Walcheren, province of Zeeland, which is rich in Trifolium species.

Description: The following species and varieties were either found after my list of Myxomycetes from the Netherlands was published (Acta Bot. Neerl. 10: 80-98. 1961) or they are recorded because further study has convinced me of their vallidity of which I was doubtful at first. There was now no need to mark species that are not on Dr. Karstens’ unpublished list, as was done in my previous paper, as these are all new records for the Netherlands.

Description: Flora of Java. The first volume (Gymnospermae to Buxaceae, according to Hutchinson’s system; 110 families) is now in the press and will be published, in print and in English, early in 1963. The whole work is planned in three volumes of c. 800 pages each. The second volume is also in the press. The original text is largely by Dr. C.A. Backer, assisted by several specialists. The editor is Dr. R.C. Bakhuizen van den Brink f. Lauraceae. At Bogor, Dr. A.J.G.H. Kostermans has concluded a 1700-page MS-bibliography of this family, which aims at completeness for the whole world. The bibliography deals with all names (infraspecific taxa included!) ever published in the Lauraceae and with all subsequent references in literature. All cross-references have been incorporated for all binomials, as well as the pre-Linnean names. The names which in the course of time have been misinterpreted have been included, which gives the bibliography a taxonomic aspect. Negotiations about publication have started, but to attain more certainty in this respect, institutes and private persons who might be interested in this work are encouraged to contact Dr. Kostermans at the Herbarium Bogoriense, Bogor, Java, Indonesia, or the Editor of the Flora Malesiana, Rijksherbarium, Leyden, Netherlands.

Description: Although our knowledge of reproductive parts of bamboos is still very defective, an adequately collected vegetative specimen is valuable and sufficient for identification. Like in tree ferns (see p. 567) and in rattans, a well-collected specimen does not need to be excessively bulky, provided the essential parts are taken. We hope that field workers will overcome the hesitation they might feel to attack this difficult but very important plant group.

Description: This paper contains some additional information and discussions as well as corrections of statements and of facts recorded in a previously published paper entitled “The generic names proposed for Polyporaceae”.

Description: During the pre-naming of some new collections made by the Forestry Service of North Borneo, Mr L. L. Forman, Kew, provisionally identified a collection from Pulau Gaya, District of Jesselton, San 20499, gathered by Dr. W. Meijer, as an undescribed species of the American genus Simaba. As he knew that I had almost finished a revision of the Simaroubaceae for the Flora Malesiana, he immediately gave notice and sent the material with the permission of the Director of the Royal Botanic Gardens, Kew, without delay to Leyden. I have to thank him most cordially for this friendly and generous gesture. Later Dr. J. A. R. Anderson, of the Sarawak Forestry Service, Kuching, kindly pointed our attention to the fact that the species had been collected in the past, both in Borneo and Sumatra, and that these specimens had been distributed as Parishia sp. In critical checking the generic identity of the specimen, Mr Forman’s opinion appeared to be correct, and the new plant has been since described as a new species in the Flora Malesiana. At the same time it appeared possible to accommodate it also in several other American and African genera as well, for example Simarouba, Hannoa, and Odyendyea. This necessitated a closer comparison of these genera, and some others, a desirability which I had earlier thought to lie outside the scope of the Flora Malesiana revision.

Description: When revising the Suriname mammals preserved in the collection of the Leiden Museum I also examined the type specimens of Echimys macrourus and Blarina pyrrhonota, described from Suriname by JENTINK in 1879 and 1910, respectively. As a result of this investigation I reached the conclusion that the two types are apparently incorrectly labelled as to locality. For Blarina pyrrhonota strongly resembles Sorex araneus Linnaeus from Europe, while Echimys macrourus shows a close resemblance to one of the forms of Rattus sabanus (Thomas), which has a wide distribution in the Malaysian subregion (see CHASEN, 1940, p. 164—167). In the literature dealing with Neotropical mammals, the systematic position of both Blarina pyrrhonota and Echimys macrourus has been the subject of much discussion, mainly based on assumptions, as no mammalogist since JENTINK has examined the types in question. Accordingly it seems of interest to give here a survey of these various discussions, and to render account of my own point of view. I am much indebted to Dr. R. G. VAN GELDER, Chairman and Assistant Curator of the American Museum of Natural History, New York, who was so kind as to send me on loan one of the specimens from the Mt. Duida region, Venezuela, which the late Dr. G. H. H. TATE provisionally considered to belong to JENTINK’S Echimys macrourus.

Description: It has been the aim of this study to give a comprehensive description of the important crinoid fauna's of the Palaeozoic core of North Western Spain (provinces Palencia, León and Asturias). This was opportune since fine collections of crinoids had been made during the years 1955—1960 by students of Leiden University (Holland). Moreover, existing collections of Spanish crinoids have not recieved hitherto due attention. Up to the present day only ten species of Palaeozoic crinoids have been known from Spain. Five new genera and sixteen new species of Spanish crinoids are now described. Fourteen previously described genera are reported for the first time to occur in Spain, either from new species or from species not yet sufficiently well known to allow specific arrangement. Six previously described species are recorded for the first time from Spain. So the total number of known Spanish crinoid species has now been raised to fifty six (thirty two genera): twenty five Emsian species, nine Couvinian species, six Givetian species, one Fransnian species, one Visean species, four Namurian species and four Moscovian species. The other species, represented by museum specimens only, are of uncertain Devonian or Carboniferous age. Camerates are far more numerous than inadunates, whereas flexibles are not known with any certainty. Camerates include thirty eight species (twenty two genera); inadunates eightteen species (ten genera). Among camerates only seven species belong to the diplobathrids; stratigraphically they seem to be restricted to the Emsian. Pterinocrinus decembrachiatus, Griphocrinus ovetensis, Orthocrinus robustus and Orthocrinus elongatus are described as new species of diplobathrids. The genera Diamenocrinus, Pterinocrinus, Macarocrinus and Griphocrinus are recorded for the first time from Spain. Orthocrinus was already known. W. E. Schmidt's species Orthocrinus planus is regarded a nomen dubium, since only poor fragments are assignable to the species. Camerates further include thirty one species of monobathrids, among which periechocrinids (fourteen species) and hapalocrinids/platycrinids (nine species) are of special importance. Stratigraphical distribution of the Spanish monobathrids is from the Lower Devonian to Upper Carboniferous. Among periechocrinids (restricted to Devonian strata) Pradocrinus is held as an independent genus with the only species P. Baylii de Verneuil, 1850 as the type-species. The genus is only known to occur in Spain. The available generic names Lenneocrinus and Pyxidocrinus were used for assignment of Spanish species. Lenneocrinus is now definitely erected with L. cirratus Jaekel, 1918 as the type-species. A diagnosis has been given on p. 29. The genus is first reported to occur in Spain from the new Frasnian species L. ventanillensis. Pyxidocrinus was proposed as a conditional name but is now erected as genus with Actinocrinus prumiensis as type-species and J. Muller as the author. A diagnosis has been given on p. 35. P. collensis and P. latus are referred to it as new species. P. San-Migueli (Astre, 1925), formerly referred to Periechocrinus and Pithocrinus and P. bifrons (W. E. Schmidt, 1932, formerly referred to Megistocrinus and Pithocrinus have now been ranked under Pyxidocrinus. Although Pyxidocrinus has a German species as the type, it is essentially a Spanish genus. Strangely enough it is only now reported for the first time as occurring in Spain. The genus Pithocrinus Kirk, 1945, with P. Cooperi Kirk, 1945 as the type-species has been emended so as to include forms with globose dorsal cups, a variable number of free arms per ray and a stout subcentral anal tube. The arms are described for the first time. For emended diagnosis see p. 46. Although Pithocrinus has an American type it is essentially a Spanish genus. P. ovatus and P. spinosus are referred to this genus as new species, P. Waliszewskii Oehlert, 1896, formerly referred to Megistocrinus is kept within it, but P. intrastigmatus Schmidt, 1932, formerly referred to Saccocrinus is excluded and used as the type-species of the new genus Stamnocrinus diagnosis see p. 59 which is believed to include Dorycrinus devonicus Springer, 1911 and two more Spanish species, not yet sufficiently well known so as to allow definite description. Stamnocrinus is restricted to Devonian strata. The new Emsian species Corocrinus? grandosensis is provisionally referred to Corocrinus because it possesses characters unknown up to now from that genus. Gennaeocrinus is first recorded from Spain from a species very similar to G. nyssa. The study of the important Devonian periechocrinid fauna has revealed that no Devonian forms can be assigned to the type genus Periechocrinus, which genus must be of exclusively Silurian age. A group of Lower Carboniferous and Mississippian species, hitherto assigned to Periechocrinus, both for morphological as for stratigraphical reasons cannot belong to Periechocrinus nor to any of the Devonian periechocrinid genera. The new genus Aryballocrinus is erected for them with Periechocrinus ? Whitei Hall, 1861 as the type-species. A diagnosis for this genus is given on p. 72. The genus includes six species, four of which were formerly referred with doubt to Periechocrinus: Aryballocrinus Whitei (Hall, 1861), Aryballocrinus tenuidiscus (Hall, 1861), Aryballocrinus awthornsensis (J. Wright, 1955) and Aryballocrinus spec. 1 (Laudon & Severson, 1953). Further are included Aryballocrinus Sampsoni Miller & Gurley, 1896, formerly referred to Corocrinus and Aryballocrinus parvus Wachsmuth & Springer, 1890, formerly referred to Megistocrinus Other monobathrids include specimens of Iberocrinus multibrachiatus Sieverts Doreck, 1951, which species proved to occur in the Moscovian of Spain. Nunnacrinus ? stellaris is first reported from the Namurian of Spain. The genus Pimlicocrinus is first recorded outside Great Britain. Pimlicocrinus latus occurs in the Namurian of Spain, whereas in England it is in the Dinantian. Another two species of Pimlicocrinus are not yet fully described. One of them is of Moscovian age and probably conspecific with a specimen from the Westfalian of Marocco. A single cup is assigned to Aorocrinus. This would mean the first occurrence of this genus outside the North American continent. Platyhexacrinus Kegeli W. E. Schmidt, 1932 is mentioned because two new specimens substitute for the lost types. Trybliocrinus Flatheanus is redescribed in great detail. The species Hadrocrinus hispaniae Schmidt, 1932 is placed into synonymy with it. Much attention has been given to the ontogenetic growth. Ontogenetic phenomena are regarded as special characters of the family Polypetidae, in which family the genus Himerocrinus Springer, 1921 is placed on the ground that it is supposed to have an ontogenetic growth largely comparable to that here described for Trybliocrinus. Platycrinicae form an important part of the Spanish fauna. Besides Platycrinus spec. ex gr. bollandensis of Namurian age and Pleurocrinus spec. ex gr. coplowensis of unknown provenance, they may all be found in Lower and Middle Devonian strata. The Spanish hapalocrinids and related platycrinids are characterized by aberrant positions of the smaller basal and by differentation of the posterior interradius. The new hapalocrinid genus Cantharocrinus with C. minor spec. Nov. as the type-species (diagnosis see p. 117) and the new species C. simplex as co-type, is still only known from Spain. The new platycrinid genus Oenochoacrinus with Oe. princeps spec. Nov. as type-species (diagnosis see p. 124) and the new species Oe. pileatus and Oe. scaber as cotypes, is still known only from Spain. The genus is erected for platycrinids with a tegmen composed of five orals and five modified first axillar ambulacrals. The genus showed to posses affinity with the Permian genus Neoplatycrinus. The better understanding of modified first axillar ambulacrals, as a character consistent with the presence of but one first primibrach and two secundibrachs in trunked armbases led to a review of the morphological relations of genera in the Platycrinicae. A suggestion for their evolution is given, based on detailed morphological comparison (see textfig. 32). Among the inadunates previously described from Spain Storthingocrinus Haugi Oehlert, 1896 and Storthingocrinus labiatus W. E. Schmidt, 1932 are regarded as nomina dubia. The incomplete nature of the specimens attributed to them, forces us to do this because their cups are undistinguishable from so many other inadunate cups. The affinity of North American Devonian crinoids with the West European fauna is once more expressed by the first record from Spain of the species Vasocrinus valens Lyon, 1857; Vasocrinus turbinatus Kirk, 1929; Vasocrinus stellaris (Schultze, 1867) and spec. cf. V. sculptus Lyon, 1857. A highly interesting inadunate proved to be a form with pentalobate stem, composed of five different joint series, two anals in cup and enlarged thecal cavity by incorporation of a smalll number of interradials and the presence of a madreporite. It is described as the new genus Situlacrinus with S. costatus spec. Nov. as the type-species diagnosis see p. 153 The genus is placed provisionally among the Barycrinidae. It would be the first Devonian form of that family and the first record from Europe. The Givetian cupressocrinid fauna has largely affinitiy with Middle Devonian fauna's in the Eifel region. Cupressocrinites Townsendi, Cupressocrinites spec. cf. C. Schlotheimi, Cupressocrinites inflatus, Cupressocrinites Sampelayoi and a species not sufficiently well presented to receive full description are described from Spain. C. inflatus and C. aff. Schlotheimi have their first mention outside Germany. The genus Aviadocrinus Almela & Revilla, 1950 is put into synonymy with Cupressocrinites Goldfuss, 1831 because all the essential characters of its type-species A. Sampelayoi occur dispersedly among Cupressocrinites species. The genera Bactrocrinites, Lasiocrinus (?), Cromyocrinus and Paradelocrinus are reported for the first time from Spain. The Devonian crinoid faunas in the province of León occur in four different levels: at the top of the La Vid formation; at the base of the Santa Lucia formation; at the top of the Santa Lucia formation; and in the middle part of the Portilla formation. The first two faunas are of Emsian age. The Emsian fauna has affinities with the Lower Devonian fauna of Western Germany and with the Middle Devonian fauna of the region West-Central New York, Kentucky, Michigan, Indiana. The Spanish Emsian fauna is the richest of all known Spanish crinoid faunas.

Description: The genus Zonophora, established by DE SELYS (Bull. Acad. Belg. (2) 21, p. 80) in 1854 for BURMEISTER’S Diastatomma campanulata from Brazil, is represented in Surinam by two species only: Z. batesi Selys 1869 and Z. calippus Selys 1869. Both species had already been reported as occurring in Surinam, and have again been collected in this country during my researches since 1955. The species Z. surinamensis NEEDHAM (Trans. Amer. Ent. Soc. 69, 1944, p. 219) was collected in Brazil (Matapaoni), close to the border of Surinam, and may for this reason be encountered in Surinam as well. In 1941 Dr. E. SCHMIDT (D. Entom. Ztschr., p. 76—96) published his “Revision der Gattung Zonophora Selys,” which contained the then known members of the genus Zonophora. However, his treatise was written without examination of the original type specimens; hence, in order to acquire a sounder basis for my study of the subject, I took the opportunity of investigating the original material during my leave in Europe in 1961. In the following pages I present a general view of my explorations, which have been founded chiefly on the material mentioned below, as well as on that from Surinam.

Description: The examination of two aberrant Pteropods collected during a trip with the whale factory-ship ”m.s. Willem Barendsz” led to the conclusion that they were animals in a resting stage. The histology and the anatomy of the totally aberrant soft parts was discussed. The shells of the specimens indicate that these animals are the species Clio antarctica Dall, 1908. One aberrant specimen belonging to the species Clio sulcata (Pfeffer, 1879), collected during the same trip with the whale factory-ship, was examined and it shows that this animal was in a stage between the resting stage and the normal, active, stage. Three specimens of the species Clio pyramidata (Linnaeus, 1767, forma lanceolata (Lesueur, 1813), collected by the Texas and the Dana expedition, were studied as they showed the same aberrations from the normal full grown form as the other three animals previously mentioned. It was clear that the three specimens of the form lanceolata were also in a resting stage and their anatomy and histology were identical with those of the aberrant animals of the species Clio antarctica Dall, 1908. The resting stage seems to have developed from a more specialized stage, as a great store of reserve food was present, while the intestinal duct was not functional and, moreover, the gonad was active. The relation and the distribution of the species Clio pyramidata Linnaeus, 1767, Clio sulcata (Pfeffer, 1879), Clio antarctica Dall, 1908 and Clio martensii (Pfeffer, 1880) was studied and it seems better to consider these species as belonging to one polytypic species and, therefore, as synonymous with Clio pyramidata Linnaeus, 1767. It may be very well possible that Proclio subteres Hubendick, 1951 also belongs to the species Clio pyramidata Linnaeus, 1767. And if that is the case, Proclio subteres Hubendick, 1951 is in all probability synonymous with Clio pyramidata Linnaeus, 1767 forma antarctica (Dall, 1908).

Description: From the many misidentifications in herbaria and the contradictions between the descriptions of many authors it became evident that the species of Trichomanes included by Desvaux, Presl, van den Bosch and Copeland under the generic name Didymoglossum and those included by Presl, van den Bosch and Copeland under the name Microgonium were particularly poorly understood. A complete revision of this group has never been undertaken. LINDMAN’s paper (1903) is incomplete, being based only on the study of about 30 herbarium sheets; moreover, his conclusions are based on misinterpretation of several species. The treatments in local floras, as, e.g. STURM’s (1859) and MAXON’s (1926) are very good, but only a small number of species are involved. The name Didymoglossum was used for the first time by DESVAUX (1827); it was taken up by PRESL (1843), and COPELAND (1938), all on the generic level. Microgonium was established as a genus by PRESL (1843). Van den BOSCH (1861) and COPELAND (1938) maintened it as a separate genus.

Description: Among the Rubiaceae collected by Dr. P. C. Heyligers near Jodensavanne, a village on the Suriname River, I found a new Psychotria species which I provisionally described as Psychotria farameoides. At the time I made this description, it was not my intention to publish it, as on account of the absence of fruits it was incomplete. As in this genus the most trustworthy characters for the determination of the position of the species are found in the fruit, especially in the pyrene and in the endosperm, it is, in my opinion, undesirable to publish descriptions in which these characters are not recorded. However, as Dr. Heyligers wanted to mention this species in the description of one of the vegetation types found in the savannas of this region, and as after all its position could be determined with a reasonable degree of probability by means of the characters in which it resembled some other species, I decided to put my scruples aside and to publish the description. Here it is. Psychotria farameoides Brem. n. spec., a speciebus quas Mueller Argovensis ad Eu-psychotriae species Bracteosas ascripsit combinatione florum subcapitatorum cum foliis basi rotundatis et vix notabile petiolatis distinguenda, a Ps. bracteata DC quam Mueller Argovensis ad Inundatas adnumeravit forma bractearum lineari-lanceolata et foliis minoribus, pro rata angustioribus, basi rotundatis et brevius petiolatis diversa, a speciebus quas Mueller Argovensis ad subgeneris Cephaëlis species Barbifloras retulit foliis aut majoribus et pro rata angustioribus aut subsessilibus, basi rotundatis et insuper stipulis brevissimis recedens.

Description: In a previous paper (GADELLA, 1961) I suggested that the basic chromosome number of the Loganioideae might possibly be x = 6. The chromosome number of Anthocleista djalonensis Chev. (2n = 60) was in accordance with this supposition. Further investigations in the Loganiaceae, however, are highly desirable. This paper deals with the chromosome numbers of 7 species of Loganiaceae. The following data might contribute to a more complete knowledge of the relationships between the genera and species of the Loganiaceae.

Description: Instead of choosing for this number a frontispiece devoted to new buildings or persons connected with botanical research we have found it fit to draw attention to the important nature preservation in the Malaysian tropics by taking a design picked from a number of posters made by students in Malaya where a great effort towards nature preservation has recently been made by the Malayan Nature Society. Elsewhere in this issue a more full digest is given of a remarkably well-illustrated and good, instructive book issued by this Society to mark its 21st anniversary, a laudible effort to reduce science, welfare of people and land in future, recreation, and due respect of man for what nature achieved through the ages, to the same denominator. In Malaya an earnest effort is going on to propagate this idea with the populace and with the administration in which foresters, biologists, and naturalists have their share, People should be proud of the natural resources and treasures of their country and this sense of noble pride in fauna and flora, rocks and rivers of the environments of their home-country should start with the schools, primary and secondary, and the colleges. This beautiful book, which is sold at a remarkably low price, provides an excellent tool in the hands of teachers. Other measures are the following; appointing reserves, national parks, and recreation lands, appropriately adorned with signs and posters at the entrances of roads and trails in order to instruct the public. Elsewhere in this issue references are found to great destructions of the original vegetation in Borneo, Lawaii, and the Seychelles. May the exemplary effort of Malaya be followed in other tropical countries before it is too late. Botanical exploration in Malaysia is still well proceeding and the important new finds in Borneo and New Guinea show that the Malaysian flora is still a most promising ground for plant hunting, not only in the way of species but also for new genera.

Description: A rather extensive series of collections of the genus Amanita from Malaya and Singapore, provided the basis of 22 species described as new. The obscure species Amanita eriophora (Berk.) Gilb., A. fritillaria (Berk.) Sacc., A. virginea Mass., Armillaria squamosa Mass., and Collybia elata Mass. are redescribed and the last two transferred to Amanita. Amanita similis Boed. is reduced to the rank of a subspecies of A. hemibapha (Berk. & Br.) Sacc. and A. hemibapha sensu Boed. described as A. hemibapha subsp. javanica. Amanita rubrovolvata Imai is recorded for the first time from outside Japan.

Description: This essay was primarily made as a background study for a lecture on ‘Transpacific Floristic Affinities, particularly in the Tropical Zone’ in a symposium on ‘Pacific Basin Biogeography: Tropical Relationships’ at the 10th Pacific Science Congress, Honolulu, August 1961 ¹). The occasion was a welcome challenge to crystallize my knowledge and views on the fascinating subject of the Indo-Pacific plant geography which has occupied my thoughts for several decades. Besides, as a corollary of plant-geographical studies on the Malaysian flora, my interest in it was distinctly restimulated by the compilation of maps of Pacific plants for the work ‘Pacific Plant Areas’.

Description: This study is a full-sounding prelude to the fundamental work on the morphology of inflorescences, which is being prepared by Prof. Dr. W. Troll of Mainz. All inflorescences in Valerianaceae are understood as modifications of one basic form, the thyrse. It is gratifying to note that forms of inflorescences, described in systematical works as for instance 1) capitate or interruptedly spicate (Plectritis), 2) compound dichasium, dichotomous throughout (cymoid Valeriana spp.), or dichotomously branched inflorescence (Valerianella), 3) ‘rispig bis fast trugdoldig’ (Phuodendron), in reality all are variations on one theme, the decussate mono-, to pleiothyrse, i. e. a simple to compound inflorescence with a racemous primary axis and cymous lateral axes. The transformations take place first of all by a favoured development of lateral axes on definite heights of the main axis (‘basi-mesotoner, akrotoner Förderungssinn’) and secondly by the number of flowers developing and the more or less pronounced tendency to form monochasia. Moreover, different forms such as loose panicles, umbels, glomerules, heads and even nearly simple racemes (Aretiastrum), originate by extension or reduction of axes of some or all orders.

Description: This paper deals with a small collection of West Indian ascidians (class Ascidiacea: sub-phylum Tunicata) made by Dr. P. WAGENAAR HUMMELINCK in 1930, 1948/49, and 1955, to which several specimens taken by Dr. J. H. STOCK in 1958/59 were added. The material collected by Dr. HUMMELINCK (indicated with Station number) has been deposited in the State Museum, Leiden, and that collected by Dr. STOCK in the Zoölogisch Museum, Amsterdam. TRAUSTEDT (1882, 1883), SLUITER (1898), and VAN NAME (1902, 1921, 1924, 1945) have already described ascidians from the West Indies, and the following 24 species have been recorded from the Netherlands Antilles, all from Curaçao.

Description: The genus Dictydium was created by SCHRADER (1797) for Cribrarialike forms lacking a cup. ROSTAFINSKI (1875) gave it its modern definition: i.e. having meridional costae which are joined at frequent intervals by fine, more or less parallel threads. He further created a genus Heterodictyon for a species (H. mirabile) which has ribs in the lower part and a Cribraria-like net in the upper. Massee in his monograph (1892) transferred Heterodictyon to Cribraria (C. mirabilis Mass.), pointing out that there is “every shade of transition between the two extremes,” and that Heterodictyon bienaszii Racib. i.e. ( Cribraria macrocarpa of the later monographs) “closely connects the genus Cribraria in the wider sense with Dictydium.” Jahn in 1901 described a variety “anomalum” of Dictydium umbilicatum (i.e. D. cancellatum Batsch), with a rigid stem “ohne die hakenformige Aufhangung in das Sporenkörbchen”, with a rather long sporangium, always without a cup, with the ribs merging into a Cribraria-like net in the upper part, and with a more persistent silvery peridium than is found in the typical form. He studied this taxon for some years, and came to the conclusion that it was not more than a variety of Dictydium umbilicatum. Later MEYLAN (Bull. Soc. Vaud. 44: 295. 1908) raised it to specific rank ( Dictydium anomalum), mentioning a similar variation in presence or absence of the cup as occurs in D. cancellatum, and never finding any “formes transitoires vers D. umbilicatum”. He further was of opinion that D. anomalum would probably be identical with Rostafinski’s Heterodictyon mirabile. In 1911 Lister reduced D. anomalum Meylan to his var. alpinum of D. cancellatum. In Bull. Soc. Vaud. 57: 305. 1932 Meylan went a step further, and sank Dictydium cancellatum (Batsch) var. alpinum Lister into Dictydium mirabile (Rost.) Meylan. In a later paper wherein G. LISTER describes D. rutilum (Journ. of Bot 71: 222, 1933), this author states that D. cancellatum var. alpinum is clearly the same as Rostafinski’s species, adding that Meylan considered this variety worthy of specific rank. Dr G. W. Martin (private communication, shortly to be published), agrees with Meylan that this taxon merits specific rank.

Description: The genus Sorocea was established by AUG. DE SAINT HILAIRE (1821) in a study about the unequality of the cotyledons but he did not describe a species nor did he cite specimens. GAUDICHAUD’s study (1844) gives only figures not accompanied by descriptions. The first publication with well-described and illustrated species of which the type-specimen is also well-perserved is MIQUEL’s treatment (1853) in Martius Flora Brasiliensis. Balanostreblus, described and figured by KURZ (1873) is known only from a cultivated specimen in the Calcutta herbarium and is undoubtedly conspecific with Sorocea guilliminiana. Three of the four Pseudosorocea species described by BAILLON (1875) belong also to Sorocea.

Description: This work was undertaken at the suggestion of Dr. J. Lanjouw and Dr. F. P. Jonker. The citation heading this paragraph indicates that the group of Caryophyllaceae with which it deals, presents unusual taxonomic difficulties. At first, it was intended to restrict the revision to the genus Gypsophila. However, in the course of the work it was realized that the small genera Bolanthus, Ankyropetalum and Phryna could not be left out of account as they had been regarded by some authors as subdivisions of Gypsophila and by others as near relatives of this genus. For this reason a complete revision of these genera too was included. The only previous revision of Gypsophila is that published by Williams (1889). His study, largely based on data derived from the literature, includes 76 species i.e. about 3/5th of the number recognized here. His views on the generic limits were strongly influenced by those expressed by BENTHAM in BENTHAM and HOOKER’s Genera Plantarum 1 (1862). Later authors did not follow him in this respect, and generally preferred BOISSIER’s delimitation (1867), so e.g. PAX and HOFFMANN in the 2nd Edition of ENGLER und PRANTL, Planzenfam. (1934). PAX had already accepted this delimitation in the first edition (1889).

Description: The taxonomic position of some Australian Ruelliinae and Justiciinae is discussed. In Dipteracanthus two new combinations are proposed, viz. D. primulaceus (F. v. Müll, ex Bth.) Brem. and D. corynothecus (F. v. Mül, ex Bth.) Brem., both originally described in Ruellia, and one new species and one new variety are described, viz. D. sessiliflorus Brem. and D. corynothecus (F. v. Müll, ex Bth.) Brem. var. grandiflorus Brem. The Australian specimens that hitherto have been referred to Justicia procumbens L (= Rostellularia procumbens (L) Nees) will have to be referred to various other Rostellularia species. Justicia kempeana F. v. Müll, is removed to a new genus Sarojusticia, which necessitates the new combination S. kempeana (F. v. Müll) Brem.

Description: Nature Conservation in western Malaysia, 1961. Edited by J. wyatt-Smith & P.R. Wycherley. An issue to mark the occasion of the 21st anniversary of the founding of the Malayan Nature Society 1940-1961. viii + 258 pp., 44 plates, maps. There is all reason to congratulate the Malayan Nature Society with her coming of age. On account of this fact, she presented herself to the world with a book that we are exceedingly glad to review here. It consists of an introduction by Mr E.J.H. Corner, F.R.S., and 46 chapters which cover surprisingly many aspects of Nature Conservation and Environment, National Parks, and Wilf Life, these being three sections of the four into which the book has been subdivided; the fourth is General. The book has been copiously illustrated with fine photographs, and many charming vignettes of animals (by Mrs Ann Milton) at the end of the chapters. Purpose of the book is, to arouse interest in the conservation of nature by setting forth what has been done, what treasures have been safeguarded thanks to these actions, and what further should be done and why.

Description: Mr Pisaar, Curator of the Hortus Botanicus at Amsterdam, told me they had indeed, not long ago, successfully marcotted a specimen labelled Chamaedorea ernesti-augusti Wendl. The circumstances with this palm were extremely favourable. Its stem is about 3 cm thick with rather short bamboo-like nodes and internodes and below each node there are along the whole stem two swollen places which can produce a node. The marcotte they used was composed of fibres and Sphagnum and did not exceed 15 cm diameter. After about half a year it was judged that sufficient roots had developed and the apical half was separated, while simultaneously the foliage was trimmed by removal of two leaves. At present the plant thrives well and has produced inflorescences. They have also tried to ”treat” a tree fern in this way but unsuccessfully.-- v. St.

Description: Cyatheaceae. Dr. R.E. Holttum, Kew, has concluded his revision for the Flora Malesiana, Series II. Ophioglossaceae. Mr J.H. wieffering, at the Rijksherbarium, is seeing the end of his summary revision of the genus Ophioglossum for SE. Asia and Malaysia.

Description: When Dr. F. G. Meyer, in a letter to Dr. Ding Hou, inquired after biographical particulars of “Heinrich Bürger”, the name of this naturalist meant nothing to me. This is not astonishing, as nearly all of his activities took place in Japan, a country outside our range of study. It took Dr. van Steenis some efforts to warm me up and in the meantime he gathered some information, mostly provided by Prof. Dr. H. Boschma at Leyden and by Prof. Dr. F. Verdoorn at Utrecht. When Verdoorn inter alia referred to Flora Malesiana vol. 1 (Cyclopaedia of Collectors) I was baffled and got intrigued, though at the time it seemed dubious whether “Burger”, who was cited there to have sent plants to Blume (1), was identical with Heinrich Bürger.

Description: This study was started as a revision of the Malaysian species of Neckeropsis, but soon it proved to be necessary to include the species from the adjacent areas. The result was a revision covering all Asiatic and Pacific species. The material studied was obtained from the following herbaria (abbreviations according to Index Herbariorum I, ed. 4, 1959): BISH, BM, BO, BR, BRI, FH, G, GL, GRO, H, K, L, M, MEL, NICH, NSW, NY, PC, PNH, SAN, SING, US.

Description: In the Flora of Tropical Africa C. B. Clarke (6) pointed out that in the collection of “Scleria foliosa Hochst., Abyssinia, prope Chire, Dillon & Petit” specimens of true S. foliosa Hochst. ex A. Rich. (4) are mixed with some of S. schimperiana Boeck. (1) and that “it would be very difficult to sort them without looking at the nut”. He referred S. dillonii Boeck. (2) to the synonymy of S. foliosa, and herein he was followed by all subsequent authors including Nelmes (3) and Robinson (5). However, already Boeckeler was aware of the fact that the Chire collection is a mixture, and on “S. foliosa Hb. Dillon et Petit. — an etiam Richardi? — pro parte (c. S. foliosa Hochst. intermixta)” he based his S. dillonii, different from S. foliosa mainly by its globose or depressed-globose, smooth nuts.

Description: Dr. J. VAN DER DRIFT (Arnhem) übersandte mir zwecks Bearbeitung eine Anzahl von Scarabaeiden, welche im Jahre 1959 mittels Subterran-Methoden in Surinam gesammelt wurden. Die Ausbeute enthielt insgesammt 11 Arten in 81 Exemplaren und trotzdem fand ich unter diese 5 Arten vor, welche ich für neue Arten halte. Eine Art konnte sogar in keine von den bisher bekannten Gattungen eingereiht werden, darum musste ich für sie auch eine neue Gattung aufstellen. Die verhältnismässig grosse Anzahl der neuen Arten ist sicherlich mit den angewandten Sammelmethoden zu erklären. Die Abbildungen sind durch meinen Sohn angefertigt worden.

Description: In the following descriptions, three new species of Micrathyria are introduced. They have been collected during the last twenty-three years of field work carried out in Suriname from the country’s northern Atlantic coast to its southern border with Brazil. Micrathyria surinamensis n. sp. belongs to the aequalis-longifasciata group, M. paruensis n. sp. is a representative of the ungulata-complex and M. coropinae n. sp. shows a close relationship with M. romani Sjöstedt. I am much indebted to Dr. RENÉ MALAISE, Curator of the Naturhistoriska Riksmuseum, Stockholm, for the loan of the type specimen of M. romani, from which supplementary notes and figures could be made.

Description: M. J. VAN DER DRIFT a eu l’amabilité de me confier pour étude les ténébrionides qu’il a récoltés au cours d’une mission effectuée au Suriname d’Avril à Octobre 1959. Cette mission ayant eu surtout pour but l’étude de la faune du sol, les ténébrionides que j’ai identifiés appartiennent essentiellement à ce biotope et la liste en est fort restreinte. Elle présente cependent un intérêt par la présence d’une nouvelle espèce appartenant au genre Gondwanocrypticus Esp.

Description: The present paper deals with the results of my investigations regarding the tenebrionid beetles of the Antilles, north of Trinidad. For this work, use has been made of the magnificent collections assembled by Dr. P. WAGENAAR HUMMELINCK, of a number of specimens gathered by Dr. H. J. MAC GILLAVRY as a student member of a geological excursion to Cuba that took place in 1933 under the direction of Prof. L. M. R. RUTTEN, and also of materials belonging to several European museums. In particular, I have examined specimens in the British Museum (N.H.); the Natural History Museum at Paris; the Natural History Museum of Amsterdam; the State Museum of Zoology, Munich; the G. Frey Entomological Museum, Munich; and lastly the Museum of Zoology of the University of Turin. I wish to express my gratitude to all those people who have made the work possible by lending me the materials mentioned above. I also wish to thank Professor R. MALARODA, Director of the Institute of Geology of the University of Turin, for his useful criticism of my geological considerations.

Description: The marine fauna of the American Atlantic coast between Cape Cod and Cape Hatteras, the Virginian area, is placed by zoogeographers in different provinces: in the Transatlantic, or in the Boreal province. It is sometimes considered to be a province of its own, or only a transition between the Boreal and Carolinian province. The mollusk fauna of the Virginian area is compiled and compared with the faunas north and south of the area. As endemism is low, there is no reason to consider the Virginian area an autonomous zoogeographical province. The fauna is too much different from that of the Carolinian area, to combine both in one Transatlantic province. As most of the species are of boreal origin, there is less reason to consider the Virginian area as a transitional region between the Carolinian and the Boreal provinces than as belonging to the Boreal province, the percentage of boreal mollusks is large enough to include it in the Boreal province. A comparison of the northern Atlantic provinces of America and Europe shows that a different zoogeographical division of both areas is necessary, as a consequence of the currents: the transition between Labrador Current and Gulf Stream suppresses a temperate province on the American East coast, such as the Celtic province is on the European West coast.

Description: Die erneute moorkundlich-pollenanalytische Bearbeitung Nordfrieslands galten u.a. der Klärung folgender Fragen: 1. Sind die in größerer Entfernung von der Küste gewonnenen Erfahrungen über den Verlauf der Waldgeschichte der Nacheiszeit ohne weiteres auf die marschen zu Übertragen? 2. Welche Einflüsse der Meeresüberflutungen auf die Entwicklung der Moore und ihrer Vegetation lassen sich feststellen ? 3. Wie ist der zeitliche Ablauf der postglazialen Meeresspiegelschwankungen in Nordfriesland, und ist es möglich, Fehldatierungen auszuschließen, welche durch Abtragung, Umlagerung oder Durchmischung der in das Marschprofil eingeschlossenen pollenführenden Moorschichten bedingt sind?

Description: The incidence of Proteocephalus filicollis in Pungitius pungitius, Gasterosteus aculeatus f. hemigymnus and Gasterosteus aculeatus f. trachurus has been studied. It is very low in both forms of Gasterosteus, but 16% of Pungitius was infected. The monthly examination of minimally 27 and maximally 223 Pungitius pungitius indicates that an annual cycle exists neither in the incidence nor in genital development. It seems probable that Proteocephalus filicollis in Pungitius pungitius is less affected by low temperatures than worms of the same species in Gasterosteus aculeatus.\nReference is made to intercurrent helminth infections.

Description: Epiphytic or usually terrestrial ferns with a short fleshy rhizome bearing only one or a few, mostly fleshy, leaves, these erect, petiolate, continuous with the rhizome, the lamina usually divided into a sterile and a stalked fertile portion; veins free or reticulate. Sporangia with a wall composed of several layers of cells, opening with a slit, containing numerous trilete thick-walled subspherical spores of one kind. Four genera, two monotypic, the others with about 60 species of almost world-wide distribution.

Description: The examination of two aberrant Pteropods collected during a trip with the whale factory-ship \xe2\x80\x9dm.s. Willem Barendsz\xe2\x80\x9d led to the conclusion that they were animals in a resting stage. The histology and the anatomy of the totally aberrant soft parts was discussed. The shells of the specimens indicate that these animals are the species Clio antarctica Dall, 1908. One aberrant specimen belonging to the species Clio sulcata (Pfeffer, 1879), collected during the same trip with the whale factory-ship, was examined and it shows that this animal was in a stage between the resting stage and the normal, active, stage. Three specimens of the species Clio pyramidata (Linnaeus, 1767, forma lanceolata (Lesueur, 1813), collected by the Texas and the Dana expedition, were studied as they showed the same aberrations from the normal full grown form as the other three animals previously mentioned. It was clear that the three specimens of the form lanceolata were also in a resting stage and their anatomy and histology were identical with those of the aberrant animals of the species Clio antarctica Dall, 1908.\nThe resting stage seems to have developed from a more specialized stage, as a great store of reserve food was present, while the intestinal duct was not functional and, moreover, the gonad was active.\nThe relation and the distribution of the species Clio pyramidata Linnaeus, 1767, Clio sulcata (Pfeffer, 1879), Clio antarctica Dall, 1908 and Clio martensii (Pfeffer, 1880) was studied and it seems better to consider these species as belonging to one polytypic species and, therefore, as synonymous with Clio pyramidata Linnaeus, 1767. It may be very well possible that Proclio subteres Hubendick, 1951 also belongs to the species Clio pyramidata Linnaeus, 1767. And if that is the case, Proclio subteres Hubendick, 1951 is in all probability synonymous with Clio pyramidata Linnaeus, 1767 forma antarctica (Dall, 1908).

Description: In der vorliegenden Arbeit wird die Geburt des Kaninchens (multipares S\xc3\xa4ugetier) und des Rindes (unipares S\xc3\xa4ugetier) beschrieben und mit der Geburt anderer S\xc3\xa4uger verglichen. Das Verhalten der Mutter bei der Geburt hat sich nicht ge\xc3\xa4ndert trotz der Domestikation. Die Geburt findet meistens statt zu der Zeit, da die Tiere gew\xc3\xb6hnlich ruhen. Dies wird von Sympathicus-Parasympathicus-Rhythmus bedingt. Die entleerten Uterusteile der Ratte und wahrscheinlich aller Multiparen ziehen sich stark zusammen, weshalb die sp\xc3\xa4teren Jungen keinen l\xc3\xa4ngeren Weg zur Vulva zur\xc3\xbcckzulegen haben und also nicht mehr von Erstickungsgefahr bedroht werden als die ersten.\nDie Lage der uniparen S\xc3\xa4uger kommst zustande infolge Formanbequemung, Gravitation und der Raumverh\xc3\xa4ltnisse in der Bauchh\xc3\xb6hle. Eine ausf\xc3\xbchrlichere Zusammenfassung von Kapitel V findet man auf Seite 23.\nDer erste Atemzug wird ausgel\xc3\xb6st durch die St\xc3\xb6rung des plazentaren Gasstoffwechsels. Nur bei asphyctischen Jungen kann die Atmung einsetzen durch die Wirkung \xc3\xa4usserer Reize (Kap. VI).\nDer spontane Nabelschnurriss der Wale und der Huftiere, ausser dem Schwein und dem Flusspferd, findet statt an einer oder mehreren pr\xc3\xa4formierten Rissstellen. Diese Stellen sind anatomisch und histologisch verschiedenartig gebaut. Bei den Tieren, deren Nabelschnur an einer willk\xc3\xbcrlichen Stelle durchbissen wird oder spontan reisst, sind diese Eigent\xc3\xbcmlichkeiten nicht vorhanden. Eine Zusammenfassung von Kapitel VII findet man auf Seite 46.

Description: During a recent survey of Pacific psammophilous and phycophilous copepods an isolated female Bomolochus was found, the identification of which, in absence of its host, proved to be particularly troublesome. It became necessary to check the descriptions of all species of the genus Bomolochus Von Nordmann, 1832, and of several other genera of Bomolochidae, in the course of which I tried to find a satisfactory grouping of the many species described.\nThis effort in so far proved to be disappointing that a fairly large number of species is so inadequately characterized that recognition, in absence of the host, is next to impossible. Taxonomy of parasitic copepods has, unfortunately, long been influenced by the obstinate notion that each host species should necessarily harbour its own parasitic species. This idea has overstressed the importance of the host, at the cost of information, particularly morphological information, concerning the parasitic animal, so that at present there is an overwhelming number of parasitic copepods of uncertain position, uncertain status or inadequate definition, impeding a much wanted natural grouping of the numerous species of parasitic Copepoda. The importance of complete structural information, especially for those species that are able to leave their host temporarily, cannot be too greatly stressed and it is gratifying to find such information in many of the modern publications (Stock, 1953, 1955; Shen, 1957; Shiino, 1957; Yamaguti, 1936, 1939, 1953, et al.). In the present paper I have presented, in condensed form, all available information on the Bomolochidae; I have suggested a subdivision of the genus Bomolochus, redescribed the female of Bomolochus bellones Burmeister and added the description of two new species. It is hoped that this paper will stimulate the redescription of doubtful or insufficiently described forms, preferably

Description: In the Flora of Tropical Africa C. B. Clarke (6) pointed out that in the collection of \xe2\x80\x9cScleria foliosa Hochst., Abyssinia, prope Chire, Dillon & Petit\xe2\x80\x9d specimens of true S. foliosa Hochst. ex A. Rich. (4) are mixed with some of S. schimperiana Boeck. (1) and that \xe2\x80\x9cit would be very difficult to sort them without looking at the nut\xe2\x80\x9d. He referred S. dillonii Boeck. (2) to the synonymy of S. foliosa, and herein he was followed by all subsequent authors including Nelmes (3) and Robinson (5).\nHowever, already Boeckeler was aware of the fact that the Chire collection is a mixture, and on \xe2\x80\x9cS. foliosa Hb. Dillon et Petit. \xe2\x80\x94 an etiam Richardi? \xe2\x80\x94 pro parte (c. S. foliosa Hochst. intermixta)\xe2\x80\x9d he based his S. dillonii, different from S. foliosa mainly by its globose or depressed-globose, smooth nuts.

Description: This is the second paper dealing with Myxomycetes collected by me in the Netherlands, mostly in the neighbourhood of Doorwerth. Specimens of the species dealt with are preserved either in my private collection or in that of the Botanical Museum and Herbarium of the State University, Utrecht (in the last named case the numbers are followed by a \xe2\x80\x9cU\xe2\x80\x9d), or in both.

Description: In the present study pollen morphology of the Euphorbeaceae is treated as an additional character in taxonomy. Besides the greater part of the genera occurring in the system of PAX and K. HOFFMANN (1931), most of the genera published after 1931 are studied. The pollen grains have been described with the aid of a terminology as simple as possible. In principle the terminology of IVERSEN and TROELS-SMITH has been followed, although in addition, many improvements of ERDTMAN have been used. One of the simplifications is the rejection of POTONI\xc3\x89\xe2\x80\x99s term sculpture. All elements occurring on the endexine are called structure elements; all structure elements together form the structure of a pollen grain. For the sake of consequence endexine apertures and extexine apertures are discussed separately. Different pollen grains are placed in different pollen types. If the differences are of minor importance, the pollen grains are placed in subtypes. Several types can have some characters in common. To express the correspondences, these types are assembled in configurations. As the pollen types in Phyllanthoideae and Crotonoideae differ distinctly, the division of the Euphorbiaceae in these subfamilies is maintained in the discussion of the results. The Phyllanthodieae can be separated in three large groups of pollen types ( Antidesma configuration, Amanoa configuration and Aristogeitonia configuration), which agrees with the grouping of PAX in 1924. The remaining small configurations belong in taxonomic respect to the genera of the Antidesma configuration. In the Crotonoideae many genera possess pollen grains with a croton-pattern. These genera should be treated as a single group. Besides this natural group, the Plukenetiinae possess pollen grains which are clearly distinguished from other genera in the Crotonoideae. Pollen grains of Omphalea are similar to those in the Plukenetia configuration. This pollen-morphological result agrees with the opinion of CROIZAT.\nThe remaining pollen grains in the Crotonoideae are less easy to differentiate in groups. One of the largest configurations is the Mallotus configuration, which includes most genera of the Acalypheae and several genera or other tribes. The Hippomane configuration is another large one. This configuration comprises the tribes Hippomaneae and Euphorbieae. The pollen grains of both tribes are very similar. The genus Pachystroma is pollen-morphologically as well as taxonomically related to the tribe Hippomaneae.\nPera, treated as a separate tribe by PAX and K. HOFFMANN, is related by its pollen grains to some genera in the Acalypheae.\nDalechampia is habitually related to the genera in the Plukenetiinae. Pollenmorphological data, however, do not support this relation. The pollen grains of Dalechampia are not similar to any other pollen type.\nThe morphology of the pollen grains of the Stenolobeae is in agreement with the opinion of PAX, that any separation of these Australian genera is an artificial one.

Description: This work was undertaken at the suggestion of Dr. J. Lanjouw and Dr. F. P. Jonker. The citation heading this paragraph indicates that the group of Caryophyllaceae with which it deals, presents unusual taxonomic difficulties. At first, it was intended to restrict the revision to the genus Gypsophila. However, in the course of the work it was realized that the small genera Bolanthus, Ankyropetalum and Phryna could not be left out of account as they had been regarded by some authors as subdivisions of Gypsophila and by others as near relatives of this genus. For this reason a complete revision of these genera too was included.\nThe only previous revision of Gypsophila is that published by Williams (1889). His study, largely based on data derived from the literature, includes 76 species i.e. about 3/5th of the number recognized here. His views on the generic limits were strongly influenced by those expressed by BENTHAM in BENTHAM and HOOKER\xe2\x80\x99s Genera Plantarum 1 (1862). Later authors did not follow him in this respect, and generally preferred BOISSIER\xe2\x80\x99s delimitation (1867), so e.g. PAX and HOFFMANN in the 2nd Edition of ENGLER und PRANTL, Planzenfam. (1934). PAX had already accepted this delimitation in the first edition (1889).

Description: The new genus Aglaothecium Groenh. is proposed to accomodate the new species A. saxicola Groenh. The development of bitunicate asci as occurring in cryptothecioid genera is compared with that of the supposedly unitunicate but thick-walled asci which are common in Lecideaceae and Lecanoraceae. The question is discussed whether bitunicate asci are always indifferent to iodine.

Description: The author introduces two new genera, Mniopetalum Donk & Sing, (based on a new species, M. globisporum Donk) and Episphaeria Donk (based on Cyphella fraxinicola Berk. & Br.). Three other genera in an emended circumscription are discussed: Stigmatolemma Kalchbr., Phaeosolenia Speg., and Cyphellopsis Donk. Rhodocyphella W. Cooke is reduced to the synonymy of Stigmatolemma; and Maireina (Pil\xc3\xa1t) W. Cooke, to the rank of a section of Cyphellopsis, which is tentatively considered to consist of a single complex species for which the name Cyphella monacha Speg. apud Roum. is temporarily used. New combinations are made in Mniopetalum (1), Episphaeria (1), Stigmatolemma (3), Phaeosolenia (2). Most of these names are used (but not validly published) in a recent work of Singer where also the genera mentioned above are described and discussed.

Description: The present paper, which is the first of a series of studies on Discomycetes, is concerned with type material of Ascobolus and Saccobolus from Spegazzini\'s herbarium, deposited at La Plata (LPS). The author is indebted to Dr. J. C. Lindquist, for sending the herbarium specimens on loan.\nThe work for this paper was facilitated by a grant from the Netherlands Organization for the Advancement of Pure Research (Z.W.O.).

Description: Four species of Fimaria Vel. are described. The following new combinations are made: Fimaria hepatica (Batsch per Pers.) Brumm., F. cervaria (Phill. apud J. Stevenson) Brumm., and F. theioleuca (Roll.) Brumm. Ascobolus vinosus Berk., A. fuckelii J. Kunze, A. piceus (Limminghe) ex Cooke, and Fimaria murina Vel. are reduced to the synonymy of Fimaria hepatica.

Description: Among the new material which was examined by me after the completion of the revision of the genus Pittosporum for the Flora Malesiana (vol. I, 5, 1957) and additions in Nova Guinea n.s., 9, 1958, 339, the following is worth mentioning: Pittosporum pentandrum (Blanco) Merr. NORTH BORNEO. Ranau Distr., Bukit Ampuan, alt. 1500 m, Meijer SAN 20289, in primary forest on hill side ridge. Note. This is the first record from Borneo; otherwise known from Formosa, the Philippine Islands, and N. Celebes.\nPittosporum pullifolium Burkill. WEST NEW GUINEA. Koebre Mts, Anggi Lakes, alt. 2300 m, Sleumer & Vink BW 14148, shrub 4 m, on forest edge, rather scarce, fruit green. Note. A specimen with young fruits on infructescences which are placed axaillary along the twigs, instead of being terminal.

Description: A. F. G. Kerr (1877\xe2\x80\x941942) worked in Siam between 1902 and 1932, originally as a doctor, later as government botanist. He made large botanical collections in Siam and surveyed the whole of that country. Our knowledge of the flora of Siam is mainly based on his collections (now completely represented at Kew and in the British Museum), which formed the materials for the Florae Siamensis Enumeratio.\nA sketch of his life and career is given, also a bibliography, including special publications devoted to Kerr or to his material and details about his collections; by means of an Itinerary the date can be found of any Kerr number as well as the locality with approximate longitude and latitude, and by means of a list originally prepared by Kerr himself and here posthumously published, for each geographic name the province and the region of Siam where it is situated.\nSeveral persons were inspired by Kerr to make botanical collections themselves, notably Anuwat, Bourke-Borrowes, Mrs. Collins, Garrett, F. H. W. Kerr, Lakshnakara, Marcan, Noe, Put, Rabil, Rock, Eryl Smith, H. M. Smith, Vanpruk, Winit, Yuang. Some information about these persons and their collections has been added.

Description: A fungus belonging to the genus Lagenidium (Phycomycetes), according to Dr. F. K. Sparrow probably L. gracile Zopf, was found parasitizing a species of Spirogyra, probably S. setiformis (Roth) K\xc3\xbctz. It was collected in a ditch with turbid water near Wageningen. The young zygospores of the Spirogyra appeared arrested in their development or even destroyed by the fungus. The fungous thallus consists of coralloid, 5-8 \xc2\xb5 wide, dispersedly septate hyphae. Extramatrical discharge tubes of the sporangia occurred. Several Spirogyra cells contained thick- and smooth-walled resting spores of the fungus, 18-21 \xc2\xb5 in diameter.

Description: The mediterranean-atlantic species Catapodium marinum (L.) Hubbard reaches its northern limit on the continent in the Netherlands. Up to 1959 only 2 localities on the Dutch coast were known. In 1961 the species was discovered in large quantities on the brackish estuary shore of the island of Goeree, by far the richest occurrence in the country. The habitat in the three Dutch localities is similar: low, sandy, dry, irregularly submersed dunes in the ecotone between xerosere and halosere, with fluctuating, but mostly low, salt content and rather high lime content; i.e. in the dry desalinated \xe2\x80\x9cKoelerion\xe2\x80\x9d-variant of the Saginetum maritimae.\nScirpus planifolius Grimm, another ecotone species, is rather common in Britain, but much rarer on the continent, although it is not an atlantic or subatlantic plant. Here it is probably diminishing by reclamation of the suitable habitats. It is a characteristic species of the \xe2\x80\x9cdisturbance ecotone\xe2\x80\x9d, the transition zone between some contrasting habitats: salt-fresh, dry-wet, rich in nutrients-poor in nutrients. In the island of Goeree it was observed in large quantities in moist dune valleys, as well in the salt-fresh transition zone as in the wet-dry one. Its ecology as a species of the alliance Agropyro-Rumicion crispi is discussed.\nFinally a new locality of the mediterranean-atlantic Trifolium micranthum Viv. is described. In the Netherlands this species was hitherto only known from a few localities. In the island of Goeree it was found in two spots in damp grazed valleys in the inner dunes poor in lime.

Description: De jaarlijkse zomerexcursie van de Commissie voor het Floristisch Onderzoek van Nederland werd gehouden van 17 tot 22 juli 1961, met als standplaats Vlijmen. Het aantal deelnemers bedroeg 17, en doordat er een voldoend aantal auto\xe2\x80\x99s ter beschikking was en de excursie enige malen gesplitst werd, was het bestreken terrein groter dan vroeger ooit het geval was en kon daardoor het record-aantal van 661 soorten en vari\xc3\xabteiten genoteerd worden. Op 17 juli \xe2\x80\x99s middags werd als gebruikelijk de naaste omgeving van het hotel (I.V.O.N.-uurhok 45-31) verkend. Op 18 juli ging men \xe2\x80\x99s morgens eerst naar de dijk te Haarsteeg (45-31) en daarna naar het wiel te Nieuwkuik (45-31). Langs de dijk erheen werden o.m. veel Plantago coronopus, Cynodon dactylon, Trifolium striatum en Scleranthus perennis gezien, en aan het wiel zelf werd de prachtige oevervegetatie, o.a. van Echinodorus repens, Gratiola officinalis, Elatine hexandra en Anagallis tenella bekeken. Ondanks ijverig zoeken werd geen spoor meer van de daar vroeger rijkelijk aanwezige Potamogeton zizii gevonden. Een verrassing leverde een afgeplagd terrein op, n.l. grote hoeveelheden Juncus pygmaeus en J. tenageia. In de namiddag werden de Moerputten bij Vlijmen (45-32), een reservaat van het Staatsbosbeheer, bezocht, waar o.a. Carex praecox werd aangetroffen. Een deel van het gezelschap inventariseerde nog de vegetatie aan de dijk bij Bokhoven (45-21) en \xe2\x80\x99s avonds hebben nog enige deelnemers de wallen van Heusden (44-28) bezocht. De 19e werd de Duiver (44-36), een reservaat van het Staatsbosbeheer in de gemeente Sprang-Capelle ge\xc3\xafnventariseerd. Een terrein met Carex dioica was gemaaid, zodat deze soort niet meer kon geconstateerd worden. Een ander terrein met o.a. Carex limosa, Equisetum variegatum, Scirpus pauciflorus en Hammarbya paludosa was echter nog prachtig. Daarna werd nog vluchtig een terrein bij Waspik bekeken (44-35) en \xe2\x80\x99s middags ging men naar moerassige hooilanden bij Labbegat, gem. Sprang-Capelle (44-36), waar een rijke vegetatie van Carex flava, vergezeld van de bastaard van C. flava en demissa werd gezien; ook Liparis werd daar aangetroffen. Vervolgens ging men naar het Galgenwiel, gem. Waalwijk (44-47), waar vooral de overvloedige oevervegetatie van Hypericum elodes de aandacht trok. Op 20 juli werden de Maasoevers bij Empel (45-22) en de Koornwaard ten oosten daarvan (45-23) bezocht. De laatste is door afgraving grondig bedorven. Tenslotte werden nog de bekende vennetjes aan de Orthense dijk (45-23) bekeken, waar als rest van de vroegere rijke oevervegetatie nog o.a. Echinodorus repens, Gratiola officinalis en Mentha pulegium werden aangetroffen; \xe2\x80\x99s avonds werd nog door 2 deelnemers een tocht naar Elshout-Heusden (44-38) gemaakt, o.a. om Leersia oryzoides terug te vinden, die daar door de Unio Heusden in 1932 genoteerd was, wat ook gelukte. Op 21 juli ging een klein groepje naar het Ulvenhoutse bos (50-14) speciaal voor de merkwaardige Rubus-flora aldaar, o.a. met Rubus myricae en pallidus en andere gedeeltelijk nog niet op naam gebrachte soorten. Onderweg werd de bekende warmwater-afvoersloot bij Dorst bekeken, waar Limnophila sessiliflora nog overvloedig groeide, maar Sagittaria graminea niet meer werd gezien. Het grootste deel van het gezelschap bezocht op die dag eerst de kleiputten bij Udenhout (45-51), o.a. met zeer veel Elatine hexandra, Echinodorus repens en Juncus tenageia; daarna de Kievitsblek ten oosten van Oisterwijk (51-11) met o.a. Deschampsia setacea, Narthecium ossifragum, Osmunda regalis en Hypericum elodes, en tenslotte het terrein met Anagallis tenella bij De Opslag aan het Wilhelminakanaal (51-21) in de gem. Diessen.

Description: From the many misidentifications in herbaria and the contradictions between the descriptions of many authors it became evident that the species of Trichomanes included by Desvaux, Presl, van den Bosch and Copeland under the generic name Didymoglossum and those included by Presl, van den Bosch and Copeland under the name Microgonium were particularly poorly understood. A complete revision of this group has never been undertaken. LINDMAN\xe2\x80\x99s paper (1903) is incomplete, being based only on the study of about 30 herbarium sheets; moreover, his conclusions are based on misinterpretation of several species. The treatments in local floras, as, e.g. STURM\xe2\x80\x99s (1859) and MAXON\xe2\x80\x99s (1926) are very good, but only a small number of species are involved.\nThe name Didymoglossum was used for the first time by DESVAUX (1827); it was taken up by PRESL (1843), and COPELAND (1938), all on the generic level. Microgonium was established as a genus by PRESL (1843). Van den BOSCH (1861) and COPELAND (1938) maintened it as a separate genus.

Description: In this paper a number of records of the putative hybrid of Asplenium adiantum-nigrum and A. ruta-muraria, found in botanical literature, are discussed. These records bear reference to finds in Spain, France, Italy, Switzerland, and Poland. Some recent authors are in doubt about the existence of this hybrid. In the opinion of the present author a specimen growing on an old wall at Enkhuizen together with a single plant of A. adiantum-nigrum and many of A. ruta-muraria doubtless represents the hybrid in question.

Description: The hybrid of Carex lasiocarpa L. and C. riparia L. O (C. x evoluta Hartm.), in the Netherlands till now only found near Wychen (prov. Gelderland) in 1955, has also been found in 1961 near Maartensdijk (prov. Utrecht). Data are given concerning the ecology of the hybrid and the plant communities in which it occurs.

Description: Corallorhiza trifida Ch\xc3\xa2tel. was found in the Netherlands for the first time in the dunes near Bergen in 1902. The author gives numbers of specimens noted during several years, up to 1942. During World War II the species disappeared from the only known locality, and this paper may be considered a kind of necrology of the species in our country.

Description: Catapodium marinum (L.) Hubbard has its northern limit on the continent in the Netherlands. Up to now it was known here from 4 localities only. In 1960 the author discovered two new and very rich localities on the isle of Walcheren between Domburg and Westkapelle. It is supposed that the plants have reached one of these localities as a result of the inundation after the great flood of 1953, and the other with rubble from Westkapelle, which village was destroyed during World War II, and inundated afterwards.

Description: The authors mention a number of plants, found by them in the provinces of Gelderland and Utrecht, deviating by their white flowers.
