    Description: The bogs of S. E. Groningen are part of the great peat-marshes extending from S. E. Drente as far as N.W. Germany inclusive. So far as the territory of Westerwolde is concerned, people have begun digging off very early. According to the map by Krayenhoff in 1816 nearly the whole peat-marsh westward from the line Blijham—Termaarsch had already been reclaimed, only a few parts still being covered with the original peat-layer (cf. map, fig. 1). The digging off east of the above line commences at the beginning of the 19th century on the borderland of Groningen and Drente. Borings were performed in three places and the samples pollenanalytically and stratigraphically examined.

    A Biosystematic Study of Neohattoria herzogii (Hatt.) Kamim (1981)
    In:  Mededelingen van het Botanisch Museum en Herbarium van de Rijksuniversiteit te Utrecht (2352-5754) vol.509 (1981) nr.1 p.23

    Publication Date: 2015-05-08
    Description: Neohattoria Kamim. is a monotypic genus of the Jubulaceae (= Frullaniaceae) with a single species, N. herzogii (Hatt.) Kamim., known from central to northern Japan and the southern part of the Kurile Islands. The present genus was segregated from Frullania by Kamimura (1961; sub. nom. Hattoria Kamim. nom. illeg., non Schust., 1961) on the basis of the branching type, the shape of the first leaf and underleaf on branch, the total lack of secondary pigmentation, the uniform cell structure of the stem in cross section, and the strongly toothed leaf lobes. The generic concept of Neohattoria was greatly expanded by Schuster (1970), who included eight species and classified them into two subgenera, subgen. Neohattoria (with a single species) and subgen. Microfrullania Schust. (with seven species); however, Hattori et al. (1972) transferred all species of subgen. Microfrullania to a newly segregated genus Schusterella Hatt. et al., thus retaining the monotypic status of Neohattoria. As already described and illustrated by Hattori (1955), Kamimura (1961), Mizutani (1961), Ladyzhenskaja (1963), Schuster (1970), and Hattori et al. (1972), Neohattoria herzogii is closely related to species of both Jubula and Frullania. Regarding the taxonomic desposition of Neohattoria, Mizutani (1961) and Mizutani & Hattori (1969) placed it with Jubula in a subfamily Jubuloideae of Lejeuneaceae and Hattori et al. placed it in Jubulaceae (s. lat.). But, Kamimura (1961), Schuster (1970, 1979), and Guercke (1978) placed it more close to Frullania, e.g. in a subfamily Frullanioideae of Jubulaceae (s. lat.); more recently, Asakawa et al. (1979b), admitting three distinct families, Jubulaceae, Frullaniaceae, and Lejeuneaceae, placed Neohattoria and Jubula in the Jubulaceae (s. str.) but Frullania and Schusterella in the Frullaniaceae.

    Description: El género Plagiochila (hepatica) esta representada en las Islas Galapagos por ocho (8) especies diferentes: P. bursata (Desv.) Lindenbg., P. galapagona Inoue, P gradsteinii Inoue, P. guilleminiana Mont., P. inouei Grolle, P. scabrifolia Inoue, P. spinifera Ångstr. y P. subplana Lindenbg. El endemismo en este género es más alto que en otros géneros de las hepaticas, con cinco (5) especies que comienzan a conocerse solamente de los Galapagos ( P. galapagona, gradsteinii, scabrifolia, inouei, y spinifera). Las otras tres (3) son comunes y ampliamente distribuidas a lo largo de la America tropical. La mayoría de las especies estan restringidas a las zonas altas-húmedas de vegetación de las Islas Galapagos (matorrales de Zanthoxylum, Miconia y pampa) excepto P. guilleminiana muy común, la cual puede presentarse en la zona seca de transición de bosque. La más amplia variación de Plagiochila ha sido vista en Isabela (Cerro Azul), San Cristobal y Santa Cruz.

    Description: It is to be hoped, that the genus Pandanophyllum Hassk. never will revive, for it is based on a bad generic description and two nomina nuda, P. palustre Hassk. (Harassas tjaai) and P. humile Hassk., the first of which is supposed to indicate Mapania palustris (Steud.) Vill., while the other name has brought about much confusion, as it has been used for Hypolytrum humile (Steud.) Boeck. as well as for Mapania humilis (Miq., partly) Vill. The first validly published description of Pandanophyllum humile Hassk. nomen nudum in Cat. Pl. Hort. Bot. Bog. 1844, p. 297 has been given by Steudel in his Synopsis II (1855), p. 134 and is based upon a specimen collected in Java by Zollinger (n. 1511, Brit. Mus., Paris), belonging to the genus Hypolytrum. So this is the type-specimen of H. humile (Steud.) Boeck. in Linnaea XXXVII (1871—1873), p. 128. Bentham and Hooker, however, accepting the interpretation of Kurz in Journ. As. Soc. of Bengal XXXVIII, part 2 (1869), p. 82 and the revised opinion of Miquel in his Ill. Fl. Arch. Ind. (1871), p. 61, included both species in their section Pandanophyllum of Mapania (Gen. Pl. III, 1883, p. 1056). A quarter of a century later C. B. Clarke divided Benth. and Hooker’s section into two subgenera, viz. Pandanophyllum, including Mapania humilis Vill. and Halostemma (Wall.), including Mapania palustris (Steud.) Vill. Consequently our present section Pandanophyllum sensu Clarke probably excludes both species, which originally belonged to it. One might be inclined to rectify the mistake by changing the name of Halostemma into Pandanophyllum and coining a new name for the other subgenus, but the principal difficulty, caused by the ambiguity of Hasskarl’s generic description can not be solved in this manner. This description calls for a bifid style (perhaps referring to Hypolytrum humile Boeck.) and 3—5 spikelets (not appropriate to Mapania palustris Vill., highly improbable as to Mapania humilis Vill. and Hypolytrum humile Boeck.). The only way out of the difficulty is to reject the name Pandanophyllum as a nomen dubium in the sense of the rules of nomenclature (art. 63) and to rename the subgenus Pandanophyllum Benth. et Hook., sensu Clarke. I propose the name Pandanoscirpus.

    Description: The originally monotypic eastern Malaysian genus Schiffneriolejeunea Verdoorn 1933 has now become a widespread, pantropical group of about fifteen species by the inclusion of species from the genus Ptychocoleus Trev. nom. illeg. Six species are known from Asia, three of which constitute the sect. Saccatae (Verdoorn) Gradst. & Terken comb. nov. These are the widespread Schiffneriolejeunea tumida (Nees) Gradst., the eastern Malaysian S. cumingiana (Mont.) Gradst. and S. nymannii (Steph.) Gradst. & Terken comb. nov. Schiffneriolejeunea tumida is a rather polymorphic species in which two not sharply defined varieties may be distinguished: S. tumida var. tumida with more or less involuted leaf margins, and S. tumida var. haskarliana (Gott.) Gradst. & Terken comb. nov. with plane margins.

    Life forms and life strategies in Nanocyperion communities from the Netherlands Frisian Islands (1980)

    Description: Nanocyperion communities (s.l.) are considered here as “warp-and-woof” communities; the Nanocyperion components are described separately as synusiae. On the Netherlands Frisian Islands, four main synusiae have been recognized. Raunkiaer life form spectra show few differences between the communities. Life strategy spectra of the Nanocyperion synusiae, based on systems for phanerogams (modified after Bakker 1966) and bryophytes, yield the clearest patterns. A comparison of the ecology of the communities and an interpretation of the spectra in terms of avoidance of stress or competition suggest that inundations and standing crop of the communities are the main factors determining the distribution of the synusiae. Winter inundations overrule the influence of differences in productivity level, which becomes prominent in drier situations.

    Description: Notwithstanding the large amount of work spent by several botanists on this family, taxonomy does not appear very satisfactory, and a general agreement on generic limits has not yet been reached. The result has been a perplexing number of generic and sectional names. The present author apologizes for his adding to the number of interpretations. This study of American Sapotaceae, primarily undertaken in connection with the Flora of Surinam, could not have been completed without the generous loan of specimens by the herbaria at Brussels [B], Berlin—Dahlem [D], Kew [K], and Leyden [L]. In 1934 the author paid a short visit to the herbaria at Brussels [B] and at Paris [P]. The collections of this family at Paris are of special interest owing to the fact that they contain the material studied by Baillon, Pierre and Dubard, and bear numerous notes and analytical drawings, especially by Pierre, attached to the sheets. A number of British Guiana Sapotaceae from the Kew Herbarium was received for determination shortly afterwards. The author feels greatly indebted to the directors of the above mentioned Herbaria for their kind help, and particularly to Prof. Dr. A. Pulle, Utrecht, under whose direction this study was undertaken.

    The genus Pausandra Radlk. (1936)
    In:  Mededelingen van het Botanisch Museum en Herbarium van de Rijksuniversiteit te Utrecht (2352-5754) vol.38 (1936) nr.1 p.758
    Details
    Publication Date: 2015-05-08
    Description: The genus Pausandra Radlk. belongs to the Tribe Cluytieae of the Euphorbiaceae. It was described by Radlkofer in 1870 in Flora LIII pp. 79—95. The genus is based on Thouinia Morisiana of Casaretto. In his paper Radlkofer discussed at length that this species does not belong to the Sapindaceous genus Thouinia, but represents a new genus of the Euphorbiaceae. As at that time female flowers were unknown Radlkofer stated that the systematic position of the new genus was still doubtful, but that most probably it should belong to a new subtribe of the Jatropheae. Two new species were described in the genus in 1873 by Baillon, P. Trianae Baill. based on Pogonophora Trianae Müll. Arg. which was published in 1864, and P. Martinii Baill. based on very young material and erroneously described by Baillon as being 3-merous, as will be discussed below. He placed the genus in the affinity of Argithamnia Sw., which is certainly not right as this genus is quite different both in habit and in flowercharacters. A fourth species was added by Müller Arg. in 1874 in Flora Brasiliensis XI. II., where he inserted the genus in the same group as was suggested by Radlkofer. No more species had been described when Pax published in 1911 his monograph of the Tribe Cluytieae Pax in Engler, Das Pflanzenreich IV. 147. III. He inserted the genus Pausandra Radlk, with the genera Givotia Griff, and Ricinodendron Müll. Arg. in a new subtribe Ricinodendrinae Pax. I think that this is the right position for the genus, though it could be placed in a separate subtribe for its penninerved, glanduliferous leaves and the capsular fruits. It was a pity that Pax published this monograph without studying the original material. He now copied Baillon’s bad descriptions and the lack of a thorough study on the genus caused the publication of several superfluous species in recent years. P. quadriglandulosa Pax et K. Hoffm. and P. extorris Standley described in 1919 and 1929 are the same as P. Trianae (Müll. Arg.) Baill. P. flagellorhachis Lanj. is identic with P. Martinii Baill., while it was proved that the latter species is not trimerous. P. integrifolia Lanj. could not be maintained in the genus. Only the two new species published by Ducke in 1925 were truly new ones. Moreover three new species were recognized in the recent collections made by Krukoff in Brazil. It is for all these reasons that it seemed to me highly desirable to give a new treatment of this genus. Perhaps several of the old and new species can be united, as one can find often only small differences, but for the present I think it advisable to keep them separate. Pausandra Radlk, has been described to be dioecious, but recently it has been proved in some species that they are monoecious, so it is probable that most of them are under special cicumstances.

    Description: Some months ago the first author published in his Studies in Moraceae II (Rec. trav. bot. néerl. XXXIII, 1936, pp. 254—276) a synopsis of the genus Clarisia R. & P. The second author traced in the Berlin Herbarium a specimen of this genus which had been described in 1821 as Excoecaria ilicifolia Spreng. As this species is identic with Clarisia strepitans (Fr. Allem.) Lanj., the name of the latter species has to be changed. As in addition some interesting specimens were kindly sent to Utrecht for determination by the Herbaria at Berlin-Dahlem (D), Geneva (G) and the Arnold Arboretum, Jamaica Plain (A), it seemed desirable to publish these notes.

    The Vegetation of the Páramos of the Colombian Cordillera Oriental (1981)
    In:  Mededelingen van het Botanisch Museum en Herbarium van de Rijksuniversiteit te Utrecht (2352-5754) vol.481 (1981) nr.1 p.1

    Publication Date: 2015-05-08
    Description: A phytosociological survey based on methods of the Zürich-Montpellier School was carried out in the páramo vegetation of the Cordillera Oriental, Colombia. The study area covers about 10,000 and comprises the páramo between the Nevado de Sumapaz (3°55'N, 4250 m), the Sierra Nevada del Cocuy (6°25'N, 5493 m) and the Páramo del Almorzadero (7°N, 4375 m). The páramo vegetation was studied along various altitudinal transects from the upper forest line (3000-3500 m) up to the lower limit of the snowcap (4800 m). A general description of the study area includes data on geology, geomorphology, soils, climate, flora, phytogeography, morphological characters of the vegetation, fauna and landuse. The evolution and Quaternary history of páramo vegetation and climate is reviewed, incorporating the first data from the Lateglacial and Holocene of the Páramo de Sumapaz. The general altitudinal zonation of the páramo vegetation was studied and is presented for both the dry and the humid side of the Cordillera. The zonal and azonal plant communities are described including their physiognomy, composition and syntaxonomy, habitat and distribution. Eighty five syntaxa from the rank of variant to that of the class are newly described, 17 of which are provisional. The vegetation is not ranked syntaxonomically yet, but described on the basis of preliminary tables. A number of azonal communities, part of them of lesser extent, are described in a similar way. The páramo vegetation is primarily determined by the tropical diurnal high mountain climate. The diversity of the páramo vegetation is related to temperature (altitudinal gradient) and to humidity (dry and wet climate). The presence of zonal bunchgrass páramo, bamboo-bunchgrass páramo or bamboo páramo mainly depends on the complex interrelation between these factors. Finally a synthesis is provided on ecology, morphology and phytogeography of the páramo vegetation of the study area.

    Description: Isoëtes Palmeri with a distribution in the High Andes from the Páramo of Venezuela to the Páramo of Ecuador is described as a new taxon, and dedicated to the then American specialist of the genus, Thomas Chalkley Palmer (1860-1934). The new species belongs to the tropical-Andeanaustral-antarctic section Laeves, described as new here as well. The publication of the new species had to be anticipated to the projected monographic treatment of the South-American representatives of the genus Isoëtes, as A.M. Cleef, Utrecht intends to base a new association, the Isoëtetum Palmeri on this new taxon, observed and collected by him at many instances within the Colombian Páramo between 1971 and 1980 in the context of the preparation of his doctoral thesis now under way.

    Description: Zu meiner Bearbeitung des surinamischen Materials der Gentianaceae für die von Pulle herausgegebene „Flora of Surinam” gehören nog einige kritische Bemerkungen. Ich muszte z.B. in einigen Fällen von der von Gilg in Engler und Prantl, Nat. Pflanzenfamilien gegebenen Einteilung der Gattungen und deren Umgrenzung abweichen. Auch stellte es sich heraus, dasz sich unter dem Material eine neue Art befand, deren Beschreibung und Abbildung unten folgen.

    Additional notes on the Rubiaceae of Surinam (1936)
    In:  Mededelingen van het Botanisch Museum en Herbarium van de Rijksuniversiteit te Utrecht (2352-5754) vol.35 (1936) nr.1 p.705

    Publication Date: 2015-05-08
    Description: Since the appearance of my „Notes on the Rubiaceae of Surinam” (in Rec. d. Trav. bot. néerl. XXXI, 1934, 248; also in Meded. Bot. Mus. Herb. Utrecht no. 11, 1934) a number of species and varieties new to the flora of that country have come to light. The majority have been collected by Mr. Rombouts during the 1935/36 expedition of the Boundary Commission who is surveying at present the border in the southern part of the colony; they were found along the River Corantyne and in the savannahs in the south-western part. One species was secured by Dr. Lanjouw, and has been mentioned already in his „Additions to Pulle’s Flora of Surinam I” (in Rec. d. Trav. bot. Néerl. XXXII, 1935, 258) and one, represented by a rather poor fruiting specimen collected years ago by the Forestry Bureau, was found among material provisionally consigned to another family. New to the flora of Surinam are the following twelve species: Alseis longifolia Ducke var. pentamera Brem. n. var., Sabicea cinerea Aubl., S. Romboutsii Brem. n. spec., S. surinamensis Brem. n. spec., Tocoyena surinamensis Brem. n. spec., Thieleodoxa nitidula Brem. n. spec., Guettarda Spruceana Müll. Arg., Psychotria Romboutsii Brem. n. spec., Declieuxia fruticosa (Willd. ex R. et S.) Kuntze, Diodia pulchristipula Brem. n. spec., Spermacoce guianensis Brem. n. spec, and Borreria verticillata (L.) G. F. W. Mey (the B. verticillata of the Flora of Surinam IV, 287 proved to be B. suaveolens G. F. W. Mey., under which name it had been recorded already by Miquel), and one variety: Sipanea pratensis Aubl. var. glaberrima Brem. n. var. Four of the ten genera to which these species belong, namely Alseis, Thieleodoxa, Declieuxia and Spermacoce, are also new to the flora of Surinam. Seven species and two varieties are entirely new, and will be described below. Before entering on this part of my task I will make a few remarks however on two of the species known already from elsewhere, namely on Guettarda Spruceana Müll. Arg. and on Borreria verticillata (L.) G. F. W. Mey, and on a third species, Coccocypselum guyanense (Aubl.) K. Sch., which is known since long from Surinam, but of which Mr. Rombouts collected a specimen differing somewhat from the older Surinam findings.

    Chromosome studies on European species of the genera Aneura and Riccardia (Hepaticae) (1981)
    In:  Mededelingen van het Botanisch Museum en Herbarium van de Rijksuniversiteit te Utrecht (2352-5754) vol.491 (1981) nr.1 p.19

    Description: Until recently relatively little attention has been paid to the study of chromosomes in liverworts. The first substantial contributions were made by Heitz (1927, 1928) and Lorbeer (1934). In the second half of this century chromosome studies on liverworts were mainly carried out in Europe (e.g. Fritsch 1972; Newton 1977, 1979) and Japan (e.g. Tatuno 1959; Segawa 1965a, b, c; Inoue 1968). Inoue (in Koponen 1979) reports that until now 28% of all bryophyte species in Japan have been investigated as to their chromosome complement. A comprehensive, but rather outdated, survey of chromosome numbers in Hepaticae and Anthocerotae was given by Berrie (1960). Work on a new, updated survey is now underway (Fritsch, in prep.). In the present article results are presented of a cytotaxonomic investigation of European species of the genera Aneura and Riccardia (Aneuraceae). Most specimens were gathered in the Netherlands, but some chromosome counts based on French and German plants are also included.

    Notes on collecting Impatiens (Balsaminaceae) (1980)
    In:  Flora Malesiana Bulletin (0071-5778) vol.33 (1980) nr.1 p.3435
    Details
    Publication Date: 2015-04-20
    Description: Because of their fleshy nature, thin leaves and membranous sepals and petals, Impatiens tend to make particularly poor herbarium specimens. If dried while still attached to the leafy part of the plant the flowers generally become badly crumpled and brittle. In such a state their more important characters become unrecognisable, and it is rarely possible to restore them to any useful degree. The leaves may also become badly crushed especially if they are not pressed absolutely flat. The collectors’ time may thus be completely wasted.

    Vanishing species: things weong between man and nature (1980)
    In:  Flora Malesiana Bulletin (0071-5778) vol.33 (1980) nr.1 p.3427
    Details

    Description: Loss of species is the key issue of conservation. Contrary to misuse of land which is visible to anybody with eyes to see, the issue of extinction is sly, treacherous, and open to clear perception only for experts. It touches on quality, and reaches far out in time: hard things to grasp for non-biologists. Thus an extra responsibility devolves on those who are in a position to know and to speak. The value of the genetic resource base has been set forth in e.g. the book by O.H. Frankel & E. Bennett, Genetic resources in plants (1970), and in the BIOTROP symposium edited by J.T. Williams e.a., South East Asian plant genetic resources (1975); Myers adds many striking facts: half the prescriptions in the U.S.A. contain a drug of natural origin. The cardiac drug reserpine, from Rauvolfia, costs $ 1.25 per gram to synthesize, $ 0.75 from natural sources. The anti-polio vaccin was developed in experiments in chimpanzees. The Amerindians in Amazonia know 750 medicinal plant species. Now the possibility of massive destruction of tropical forests — where most species are located — casts some frightening shadows on the future. The question how to cope with the threat appears to be connected with human ethics and the international order. Consequently, most publications on the subject suffer from a partial lack of maturity: don’t look to Myers for ethics, nor to the Routleys for biology. It seems therefore advisable that on the part of all disciplines a common fund of knowledge and insight be built up. In my efforts, great stimulation was received from correspondence with Dr. Willem Meijer (Botany, University of Kentucky, Lexington, Ky. 40506, U.S.A.), who in his disinterested manner never fails to come up with things true and shocking.

    Description: Several aspects of the sexuality in Mucorales are discussed. It is stated that neither heterothallism nor homothallism are absolute conditions and that a continuum exists between zygospores and azygospores. Mating type switching as known in ascomycetous yeasts would explain several up to now inexplicable phenomena.

    Description: Among the collections of Knema acquired by the Rijksherbarium since the publication of my new account of the genus Knema, in Blumea 25, 1979: 321 — 478, a few specimens caused problems with the identification, and at closer examination these yielded facts of interest which are published here. Some specimens represented stages not yet known, for instance fruits, or male flowers, while other specimens meant a significant range extension of the species. Two new species and one new subspecies are described. For easy reference, the sequence and numbers of the species presently treated correspond with the numbers as used in the account of 1979. The new species bear the number of the species after which they appear in the general key of 1979, with the addition ‘-bis’.

    Some preliminary notes on the Algae collection Weber-van Bosse (1936)

    Description: This extensive collection, famous among algologists both of the Old and the New World, forms part of the collections of the National Herbarium (Rijksherbarium) Leiden since 1934. About fifty years ago it was started by Mrs. Dr. A. A. WEBER-VAN BOSSE (1852—hodie), an enthusiastic pupil of HUGO DE VRIES. The colonies of Nostoc, living in the ditches round about the Dutch village of Doom, evoked her admiration, which was the primary cause of an intense study in the freshwater as well as in the marine Algae. In the harbour of Den Helder North Sea Algae were collected; by collecting Algae on trips to the French Atlantic Coasts and several times to Norway (1883—1885) and further on a South African journey (1894—1895) the herbarium grew, as it did by the Malaysian specimens collected in Java, Celebes, etc. (1888—1889). During this Malaysian tour Mrs. WEBER worked in Tjibodas, where she described the new genus Phytophysa. In Sumatra (West Coast, Lake of Manindjau) she discovered in collaboration with her husband, MAX WEBER, a new case of symbiosis between Algae and Sponges.

    A S.E.M.-investigation on the development of free carpels (1981)

    Description: The early development (ontogeny) of the carpels of 20 species belonging to 8 apocarpous families was investigated with the scanning electron microscope. The results indicate that on the floral apex a circular or a convex meristem develops into an obliquely ascidiate primordium by unequal growth of its periphery. By further unequal growth it develops into a young carpel. The terminal mouth of a cup becomes the lateral cleft of a carpel. The different forms of the young carpels in different species are defined by the varying degree of development of the adaxial region of the initial meristem and/or its margin on the side of the floral apex. This hypothesis is theoretically evaluated.

    Description: Thanks to the kind cooperation of Dr. ROBERT PILGER, Director of the Botanical Gardens and Museums at Berlin-Dahlem, I have recently had the privilege of studying and photographing a unique specimen belonging to that institution, which bears the words „Schizostachyum Blumii nobis”, in the hand of NEES, the author of the species. Although there are no data on the sheet to indicate its source, or the date of the determination, this presumably represents NEES’S type³) of this species (which is the type species of the genus). At any rate, the available evidence 4) points to that conclusion, and the specimen agrees in all respects with NEES’ description of the genus and of the type species (NEES, 1829, pp. 534—5). Since the original characterizations are so brief and, since those parts referring to the spikelets are so difficult to interpret, I present here a full description 5) of the rather fragmentary type specimen.

    Description: In the present work details are given in the first place for the Malesian Olacaceae, representing the basis of my forthcoming treatment of the family in ‘Flora Malesiana’, in which full descriptions of the Malesian genera and species will be given. As the Olacaceae of Malesia are connected with those of South and Southeast Asia on the one, and those of Australia and the Pacific on the other side, it has been necessary to study the respective materials too. A part of the Malesian genera is represented also in Africa inch Madagascar, and even in Central and South America; the appertaining species have been studied but are not mentioned in this paper. A critical elaboration of the family for Africa and America is urgently needed, but will, as far as can be seen, be of no influence of the delimitation and scientific names of the Asiatic-Malesian Olacaceae.

    On Decalobanthus, a new genus of Convolvulaceae from Sumatra (1936)
    In:  Blumea - Biodiversity, Evolution and Biogeography of Plants (0006-5196) vol.2 (1936) nr.2 p.98
    Details
    Publication Date: 2015-03-06
    Description: Being occupied with studies on the Convolvulaceae of Netherlands India I met with a remarkable specimen in the Buitenzorg Herbarium, collected by Dr. O. POSTHUMUS during the expedition in Djambi (Sumatra) in the year 1925. At first sight this plant seemed to be a Merremia. A closer examination, however, soon showed some important differences with that genus, especially in respect to the corolla, which has a long, narrow and rather fleshy tube and a limb with 5 short, reflexed (or patent?) lobes. Each lobe is deeply bifid, so that the limb appears 10-lobed. The middle part of the lobes is fleshy just as the tube; it corresponds with a midpetaline field of the corolla of most genera of Convolvulaceae, the lateral parts of the lobes (lobules) are much thinner, membranaceous and nerved. They represent the interpetaline fields of the Convolvulaceous corolla. In general there is a resemblance with the essential corolla construction of many species of Erycibe, where the lobes are also bifid and possess a thick middle part and two membranaceous lobules. The lobules in the new genus are not fully equal in size, those on the right of each lobe, as seen from the inside of the corolla being always slightly larger. The corolla is fully glabrous or bears some papillae at the base of the filaments. The pistil has a two-celled ovary, each cell with 2 ovules and bears a long, filiform style with two globular, papillose stigmas, exactly as in Merremia. I suppose this plant to be closely related to that genus, but as the corolla with its fleshy tube and remarkable lobes is so different from all other species, it is impossible to incorporate it in Merremia without important alteration of the generic limits. I, therefore, propose to establish a new genus, under the name of Decalobanthus (derived from dexa, ten, λoβoς, lobe and άνζος, flower).

    Description: Being engaged during several years with a revision of the grasses preserved in the Rijks-Herbarium at the University of Leyden, my attention was called to the group of the Stipeae, and especially to the very difficult genus of Aristida. After an exhaustive study of the literature, I thought it desirable to have a monograph of this genus, containing extensive keys for the determination of all the species hitherto known, and I resolved to prepare such a work. It has been my good fortune that I had at my disposal not only the valuable collections of the Rijks-Herbarium, but that by the courtesy of the directors of the great herbaria in Europe and in America, I could study many thousands of specimens, among them authentic specimens and types. So several years elapsed before the revision was finished. Before I am going to publish my work, it seemed desirable to prepare a preliminary paper on the subject, dealing with the literature studied and the results of the critical examination of the types, moreover the new species found in herbaria are included in this paper. To find easily the original description and the type specimen, I give in alphabetical order all the species and varieties hitherto described, no matter if they are accepted in my monograph as valid or not.

    Description: Owing to their limited possibilities for either active or passive dispersal, their association with the soil habitat, their vulnerability towards a dry atmosphere, and, in fact, on account of their general ecology and ethology, Diplopoda among arthropods are surely one of the most important classes in relation to the study of historical biogeography. For the class as a whole the sea appears to be an unsuperable barrier as is proved by the almost complete absence of endemic taxa on oceanic islands. In many cases lowland plains also act as severe obstacles against the dispersal of millipedes. The presence or absence of diplopods on islands or continents, therefore, may give a strong argument in favour or against any supposed former land connection. The long geographical isolation of the Australian continent and the absence of endemic higher taxa seems to imply that most, if not all, of its diplopod fauna dates from the time this continent was solidly attached to other southern continents, i.e. the Mesozoic. Subsequent penetration of fauna elements from the north or northwest seems utterly unlikely, although perhaps not entirely impossible.

    Über die obersenone Gattung Rhombodus einen durophagen Stachelrochen (1926)

    Description: In der obersenonen Mastrichter Tuffkreide finden sich kleine Zähne, die durch ihre glatten Kauflächen und die Furchen an den Seiten des oberen Teiles an Kauplatten von Myliobatis erinneren, einen Rochentypus, der ein an durophage Lebensweise angepasstes Gebiss hat. Niemals findet man aber die für diese Familie so typische langgestreckte Form der Zahnplatten; die Zahnoberfläche hat immer rhombische Form. Dames hat eine ausführliche Beschreibung von diesen Zähnen gegeben, die er für Reste eines Cestracion-artigen Namen Rhombodus Binkhorsti Haies hielt, dem er den gab. Ich möchte hier nur noch einige kurze Bemerkungen hinzufügen. Die Abbildungen (fig. 1) zeigen den typischen rhombenförmigen Umriss der Kaufläche (d). Die durch eine in der Richtung der kurzen Diagonale verlaufende, tiefe Rinne in zwei Hälften geteilte Wurzel hat ebenfalls die Gestalt eines Rhombus (fig. 1, b, e). An der Grenze von Krone und Wurzel findet sich an der einen Seite eine Rinne, an der anderen Seite eine vorspringende Leiste (fig. 1 c). Zusammen mit den verticalen Furchen, mit denen die Seiten versehen sind, hat diese Leiste zur Verbindung der Zähne untereinander zu einem Mahlpflaster gedient. Neben dieser regelmässigen Form, die besonders den grösseren Zähnen eigen ist, fanden sich aber Exemplare, die eine Abweichung zeigen, indem nämlich entweder zwei Seiten eines spitzen Winkels des Rhomboïds länger sind wie die beiden anderen, oder das Rhomboïd unsymmetrisch zusammengepresst ist. Es scheint mir, dass dies nicht eine zufällige Variation ist, sondern dass wir gerade durch diese Eigentümlichkeit etwas mehr über die ganze Zusammenstellung des Gebisses erfahren können. Wie ich unten noch näher auseinandersetzen werden, muss man nämlich Rhombodus zu den durophagen Stachelrochen stellen. Bei diesen findet man sehr oft gerade die grössten Zähne in der Mitte des Kiefers. Wenn man nun die Zahl der Zahnreihen, wie es gewöhnlich bei den grosszähnigen Rochen der Fall ist Rhombodus-Unterkiefers zu 7 bis 9 annimmt, so könnte man das Gebiss eines auf eine Weise rekonstruieren, wie es fig. 3 A zeigt, (wobei die verschiedenen obengenannten Formen vorkommen). Es wäre wohl ein grosser Zufall wenn man noch einige Zähne im ursprünglichen Verband finden würde. Wenn einmal die knorpeligen Kiefer aufgelöst sind, bieten die Seitenfurchen nicht genug Festigkeit und fallen die einzelnen Zähne auseinander.

    Description: The formation of thick piles of flysch-like sediments needs the existence of narrowed seas, active denouement of neighbouring continents, and generalized marginal subsidence. These conditions are present during the initial and final stages of Wilson’s perceptive cycle. In this context, the Late Precambrian flysch of the Iberian Massif must be related to the initial rifting, whilst the Culm of southwestern Iberia was accumulated during an episode of Upper Palaeozoic subduction that remained active after the impingement of Iberia against North America. Culm sediments shed from the uplifted collision zone and fed into a remnant ocean that remained at the nonsutured southern border of Iberia. This model of synorogenic flysch formation has been described elsewhere for similar plate arrangements. On other grounds this model provides a framework that explains the different structural and magmatic trends of the Ossa-Morena Zone (near the active margin) in the context of the rest of the Massif (basement reactivation). In addition to this, it seems to support a partly primary origin for the Iberian arc versus a secondary origin.

    Description: Da die Originale der von Göppert aus dem Tertiär von Java beschriebenen Arten Piperites Hasskarlianus und Junghuhnites javanicus nicht mehr vorhanden sind, die vorliegenden Beschreibungen für eine Bestimmung aber nicht ausreichen, so sind sie aus der fossilen Flora Javas zu streichen. Das gilt auch von Miquelites elegans, dessen schlechte Erhaltung eine sichere Bestimmung unmöglich macht. Bredaea moroides dagegen ist ebenso wie Naucleoxylon spectabile Crié sowie ein bisher unbeschriebenes Kieselholz von Java eine Dipterocarpacee. Die Stücke werden beschrieben als Dipterocarpoxylon moroides, D. spectabile und D. Göpperti n. sp. Die Frage, ob es möglich ist, diese wie andere fossile Dipterocarpoxyla bestimmten rezenten Dipterocarpaceengattungen zuzuweisen, soll später erörtert werden. Frankfurt a/M.

    Description: This compilation of stratigraphic and structural data accompanying the (re)issue of the 1:50000 sheets completes the project initiated by Prof. L.U. de Sitter in 1950. The total area mapped comprises about 400 km² in a strip more than 150 km from east to west. This part of the Hercynian tectogene is characterized by a very consistent sequence of Palaeozoic shelf sediments only interrupted by syn- to late-orogenetic flysch-molasse development. Neither of these sequences lend themselves to a simple geosynclinal model. Only the suprastructures of the orogene are exposed here; essentially decollement thrusting and folding. Fold and thrust vergences vary through 180° giving the centripetal pattern of the well-known Knee of Asturias. Very minor amounts of igneous rock have been mapped although activity in some form has been registered throughout most of the systems represented. The degree of metamorphism is so slight to have been negligible for the mapping.

    Effects of early starvation periods on zoeal development of brachyuran crabs (1981)
    In:  EPIC3BIOLOGICAL BULLETIN, 161, pp. 199-212
    Details
    Publication Date: 2019-07-17
    Description: Larvae of the crabs Menippe mercenaria Say (Menippidae), Panopeus herbstii Milne-Edwards, Neopanope sayi Smith (Xanthidae), Sesarma cinereum Bosc (Grapsidae), and Libinia emerginata Leach (Majidae) were reared in the laboratory. Starvation periods different in length and timing within the first zoeal stage were studied as to their effects on later development and survival rate. After 1-3 days of initial feeding, most larvae had accumulated enough reserves to reach the second stage, independently of further food availability. The development of the survivors was delayed in the following stages, and their later mortality rate was higher than the fed controls. Starvation periods commencing directly after hatching of the larvae exert far stronger negative effects than those beginning later. All observations suggest a particularly sensitive phase in the beginning of larval life in brachyurans. When initial starvation periods exceed the point-of-no-return (PNR), the larvae will die later, even if feeding begins long before the energy reserves are depleted. Temporary lack of suitable prey may be an ecological factor controlling the survival of crab larvae as effectively as physical factors.

    Starvation resistence in first stage zoeae of brachyuran crabs in relation to temperature (1981)
    In:  EPIC3JOURNAL OF CRUSTACEAN BIOLOGY, 1, pp. 518-525
    Details
    Publication Date: 2019-07-17
    Description: Resistance to starvation in early larval stages of six species of brachyuran crabs representing four families was observed at various constant temperatures. In the optimal temperature range of 25-30°C for these warm temperate crab larvae, survival time of starved zoeae was longer than the development duration time in fed zoeae, while at lower temperatures the relationship of these two duration periods became inversed. This response pattern is found in larvae of the mud crab Rhithropanopeus harrisii and is considered to be typical for warm temperature brachyuran larvae. It indicates that reserved utilization is strongly controlled by temperature, but not to the same degree as development.

    Description: Early diagenetic ultrastructural alterations of benthic foraminifers of the genera Elphidium and Ophtalmina from the shallow water sediments of the Kiel Bight were investigated by scanning electron microscopy. Pure solution patterns were deduced from supplementary experiments.Several carbonate destroying processes can be specified by ultrastructural patterns of the shell surfaces. Based on these patterns three zones are established, each showing different mechanisms of shell fragmentation: 1) zone of abrasion, 2) zone of disintegration, 3) zone of corrosion. This zonation depends on the water depth and is caused primarily by water agitation and by undersaturation of the bottom water with respect to carbonate.

Reproductionoccurs all the year round, but 2 maxima and thus, 2 main generations per year can be observed: a weaker onein winter, and a more pronounced one in late spring/early summer. Biochemical composition and energycontents of J. falcata show only in part a seasonal cycle. There is an inverse relationship between the proteinand lipid fractions, whereas the former is negatively, the latter positively correlated with the amount ofsuspended food in the water. Protein, carbohydrates, lipid and the weight-specific energy equivalent show adecreasing trend with increasing size of the amphipods, while chitin significantly reveals an opposite trend.

    Influence of starvation on the larval development of Hyas araneus (Decapoda, Majidae) (1981)

    Publication Date: 2019-07-17
    Description: The influence of starvation on larval development of the spider crab H. araneus (L.) was studied in laboratory experiments. No larval stage suffering from continual lack of food had sufficient energy reserves to reach the next instar. Maximal survival times were observed at four different constant temperatures (2°, 6°, 12° and 18°C). In general, starvation resistance decreased as temperatures increased: from 72 to 12 days in the zoea-1, from 48 to 18 days in the zoea-2, and from 48 to 15 days in the megalopa stage. The conclusion, based on own observations and on literature data, is that initial feeding is of paramount importance in the early development of planktotrophic decapod larvae. Taking into account hormonal and other developmental processes during the first moult cycle, a general hypothesis is proposed to explain the key role of first food uptake as well as the response pattern of the zoea-1 stage to differential starvation periods.

    Notes on Agave in Aruba, Curaçao, Bonaire and some parts of the South American continent (1936)
    In:  Mededelingen van het Botanisch Museum en Herbarium van de Rijksuniversiteit te Utrecht (2352-5754) vol.29 (1936) nr.1 p.223

    Description: This publication deals with some agaves which were collected by me participating as biologist in a geological excursion under Prof. Dr. L. M. R. Rutten and Mrs. Dr. C. J. Rutten-Pekelharing, in the beginning of 1930, to the West Indies. From 14 April to 4 May we camped in the western part of Curaçao, from 10 May to 10 June Bonaire was visited and from 16 June to 9 July we passed through Aruba. In preference to the collection of a large number of different forms of Agave, an intensive investigation of the forms found on a few localities was made. I hoped thereby to acquire some information about the variability, and insight into the problem of the concept of species, not to be obtained by the study of herbarium material. — Other material was collected during an excursion to the mainland, following an invitation by the „Caribbean Petroleum Company”.

    Studies on Colombian cryptogams XIII. Oil bodies and terpenoids in Lejeuneaceae and other selected Hepaticae (1981)
    In:  Mededelingen van het Botanisch Museum en Herbarium van de Rijksuniversiteit te Utrecht (2352-5754) vol.512 (1981) nr.1 p.231

    Description: Data on structure and chemistry of oil bodies are being provided for twenty species of leafy Hepaticae, most of them belonging to Lejeuneaceae. Oil bodies are described as new for Symbiezidium, which stands out among Lejeuneaceae by its large, Bazzania-type oil bodies. The observed occurence of segmented as well as homogeneous oil bodies in Archilejeunea and Dicranolejeunea constitutes a further break-down of what was generally considered a stable generic character in Lejeuneaceae. Detected chemical compounds include a large number of unidentified terpenoids. Sesquiterpene lactones, traditionally considered important chemical markers for Frullaniaceae, were newly detected in Lepicolea (Lepicoleaceae), Clasmatocolea (Lophocoleaceae) and Omphalanthus (Lejeuneaceae). Of particular chemotaxonomic interest is the discovery of large quantities of pinguisane-type sesquiterpenes in Brachiolejeunea subg. Plicolejeunea, Trocholejeunea and Acrolejeunea, corroborating the close morphological relationship among these three groups, as well as the occurence of two morphologically and chemically distinct races in Gongylanthus granatensis. Obeserved intraspecific chemical variation in Marchesinia brachiata is considered dubious and possibly related to the different states of preservation of the material. Further taxonomic notes include new synonymy in Dicranolejeunea (D. cipaconea (Gott.) Steph. = D. circinnata (Spruce) Steph. syn. Nov.) as well as a key to the five Andean species of Omphalanthus Nees. The morphological circumscription of Omphalanthus is expanded by the inclusion of Brachiolejeunea paramicola Herz. (= O. paramicola (Herz.) Gradst. comb. nov.), characterised by the pluriplicate perianth.

    Description: In the spring of 1966, the junior author (H. Inoue) made a bryophyte collecting trip to Ceylon (now Sri Lanka) with the support of the Japan Society for the Promotion of Science. The collections have served as a basis for reviews of individual liverwort genera or families occurring in Ceylon, e.g. Frullania (Hattori, 1979) and Plagiochila (Inoue, 1979). The present paper deals with the species of Lejeuneaceae subfamily Ptychanthoideae, which comprises the more robust members of this large tropical family. In his catalogue of the liverworts of Ceylon, Abeywickrama (1959) recorded 18 species of Ptychanthoideae, belonging to the genera Archilejeunea (1 sp.), Brachiolejemea (1 sp.), Lopholejeunea (2 sp.), Mastigolejemea (2 sp.), Ptychanthus (4 spp.), Ptychocoleus (5 spp.), Spruceanthus (1 sp.), Thysananthus (1 sp.), and Trocholejeunea (1 sp.). Unfortunately, his catalogue does not provide precise information on specimens or literature on which individual species records for Ceylon were based. Most of the species listed by Abeywickrama had been treated by Verdoorn (1934) in his monograph of Asiatic Ptychanthoideae. Some are now considered synonyms, however, whereas in other cases some doubts may be cast about the correctness of the identification. Since we have not been able to locate all specimens on which previous Ceylon records of Ptychanthoideae were based, the present review should be considered preliminary.

    Description: In plots B1, 2, and 4 in 1978 only a single species once covered over 12.5% of the surface: Leontodon hispidus. A few species covered sometimes about 5-10%, like Briza media, Triselum flavescens, Lotus corniculatus, Leontodon hispidus, and Knautia arvensis. In the course of the study the occasional dominance of certain species disappeared (Table 2). Most species covered less than 5%, but the number of individuals often fluctuated strongly from one species to another. In plots B3 and B5 a much stronger dominance could be observed than in the non-fertilized plots (Fig. 5). In 1978 the grasses Festuca rubra and Dactylis glomerata covered from 10—40% of the surface, the coverage of other species, particularly forbs, amounting to less than 1%, e.g., Ononis repens, Plantago lanceolata, Ranunculus acris, and Chrysanthemum leucanthemum. A few constantly present forbs, initially covering about 25%, like Centaurea pratensis and Lathyrus pratensis in plot B5 did not keep up this high coverage. This also holds for forbs that established themselves in the fertilized plots after a few years and attained a rather high coverage, like Heracleum sphondylium in plot B3.

    Description: The rice weeds project. In 1976, a joint project was set up under the aegis of the Netherlands University Foundation For International Cooperation (NUFFIC, Box 90734, The Hague), by the universities of Utrecht and Amsterdam and the Royal Tropical Institute (KIT) on the Dutch side, and BIOTROP (Box 17, Bogor) on the Indonesian side. Coordinators are Professor R. van der Veen and Mr. P.J. van Rijn. Its objective is the study of weeds and their ecology in the rice fields of Indonesia. A sharp distinction between dry and wet rice fields cannot be made for this kind of work: the dikes in the wet rice areas often carry dry rice weeds, and where locally fields are irrigated but part of the time, the weed flora assumes a mixed or successional character. More workable is the distinction between permanent rice fields on the one hand, and those under shifting cultivation regimes on the other; the latter have been excluded from the study.

    Wood anatomy of the Neotropical Melastomataceae (1981)

    Description: The wood anatomy of 47 genera of the neotropical Melastomataceae is described in detail. The wood anatomy of the neotropical part of this pantropical family supports the subdivision into two groups: the subfamily Memecyloideae (the genus Mouriri) and the subfamily Melastomatoideae (all other genera). A relationship of Mouriri with other representatives of the family is not supported by the wood anatomical characters, because of differences in fibre type, vessel distribution, and the fibre length/vessel member length ratio, and the presence of included phloem in Mouriri. The subfamily Melastomatoideae is a fairly homogeneous group. Although some characters are very pronounced in some tribes and scarce or absent in other tribes, most tribes show a wide overlap in their wood anatomical features. An important means to distinguish to a certain extent between tribes is the size and shape of the intervascular pits combined with the size and shape of the vessel—ray and vessel—parenchyma pits. Three groups can be recognized: type 1. all pits round to slightly oval; type 2. intervascular pits round to oval, and the vessel—ray and vessel—parenchyma pits more elongated, oblong to scalariform; type 3. all pits round to oblong and scalariform. Other diagnostic characters are the parenchyma distribution, and the distribution of the fibre pits. The tribe Blakeeae can be separated from the other tribes due to the presence of druses and 2-4-seriate rays. The relationship between wood anatomical characters and habit and habitat, as well as possible phylogenetic trends in the family and classification of the neotropical tribes are discussed.

    Description: Unter allen Flechten unterscheidet sieh die nur aus Norwegen bekannte Gattung Moriola dadurch, dass ihr Lager aus Goniocysten besteht, das sind kugel- oder länglichrunde oder unregelmässig gestaltete braune Behälter mit netzartiger Oberfläche, von denen braune, zylindrische oder schwach torulöse Hyphen entspringen und bis zur nächsten, manchmal weit entfernten Goniocyste hinkriechen. Auf diesem Wege, auch wenn sie zu mehreren nebeneinander herlaufen, vereinigen sie sich nie zu einer strauch-, oder blatt-, nicht einmal zu einer krustenformigen Lagermasse. Diese besteht ausschliesslich aus zerstreuten Goniocysten und den sie verbindenden Hyphen, die bei Moriola pseudomyces (Fig. 1—4) meist über morschem Holz, bei Moriola sanguifica über fremdem Algenlager ausgebreitet sind. Die braune Panzerkruste der Goniocysten entsteht dadurch, dass die dünnen zylindrischen Hyphenzellen unter Beibehaltung ihrer Dicke (2 µ), stark in die Breite wachsen und die Gestalt von Kugelsektoren annehmen. Sie werden meistens nicht viel über 2 µ dick, können aber bis 4 µ dick werden, wenn sich die Aussenwand höckerartig verdickt.

GROENHART an mich übersandten Flechte (Fig. 5—7) sind von ihm in 3000 m Höhe auf Java gesammelt worden und entwickeln ihre sporenreichen Perithezien auf einem etwa 1 cm mächtigen, lockeren Lagermasse von fast rein schwarzer Färbung. Diese rührt von Holzkohle her, die in grösseren oder ganz kleinen Bruchstücken, selten in Form angekohlter Zweige zwischen und unter den Goniocysten liegen. Die in den Goniocysten der tieferen Schichten enthaltenen Gonidien sind alle abgestorben und sehen jetzt braun aus. Nur in den Goniocysten der obersten Schicht sind die Gonidien noch jugendfrisch, sehen hellgrün aus und heben sieh deutlich von der dunkelbraunen, 4 µ dicken Kruste ab: eine einfache d.h. einkammerige Goniocyste mit 21.8 µ. Durchmesser, so dass auf den Innenraum fast 14 µ Durchmesser kamen; in ihr hatten drei Gonidien Platz. Bei einer anderen, zusammengesetzten Goniocyste hatte sich an diametral gegenüberliegenden Punkten der Goniocyste je eine Gonidie angesetzt und war von der braunen Kruste auch noch umwachsen worden, so dass die beiden kleinen Endkammern je eine Gonidie enthielten, die Mittelkammer deren drei. Es kommen aber auch noch grössere zusammengesetzte Goniocysten vor, deren Mittelkammer 5 und mehr Gonidien enthält.

    Description: Haines (1924), Fischer (1928), Mooney (1950), Panigrahi et al (1964), and other workers’ from their studies on the vegetation and flora of Orissa recorded 25 genera and 54 species belonging to the family Orchidaceae. Exhaustive collections made by me since 1968 have yielded a wealth of varieties of forms of orchids, which I have identified with 100 taxa (excluding certain novelties) belonging to 31 genera. I describe here one new species and a variety of the genus Habenaria Willd. Both the taxa resemble in general Habenaria foliosa A. Rich., but differ from it by a number of diagnostic characters.

    Description: C. G. G. J. VAN STEENIS, Maleische Vegetatieschetsen — Toelichting bij de plantengeografisohe kaart van Nederlandsch Oost-Indië (Sketches of Malaysian vegetations — Comments to the phytogeographical map of Netherlands East India) — Reprinted from the „Tijdschrift van het Koninklijk Nederlandsch Aardrijkskundig Genootschap”, Ser. II, Vol. 52, Jan.-March-May 1935, 112 pp. (repagination [Pages in the original: 25—67, 171—203, 363—398] with 46 photographs, 36 of which in the reprint only, and a phytogeographical map. The reprint preceded by a short preface, a (too) short index and a dedication to FRANZ JUNGHUHN „as a memory to his arrival in Java, one hundred years ago”. It is a great pleasure to me indeed to announce here, more particularly on behalf of those readers who are not familiar with the Dutch language, this excellent work on the phytogeography of Malaysia, published in the Journal of the Royal Netherlands Geographical Society and therefore, moreover, likely less accessible to many botanists abroad. The author has, though only about 6 years engaged in botanical work in the tropics, gathered a remarkably thorough knowledge of the rich flora of this region, no doubt one of the most interesting ones, from a biogeographic standpoint, on earth. As the phytogeography of these parts has mostly, since JUNGHUHN’S „Java” (1854), been only dealt with in scattered papers, VAN STEENIS has in the publication under reference, as well as in some others that preceded it ¹), done a pioneer work in his attempt to give a comprehensive and more or less complete survey of the current problems. Our gratitude and admiration is not in the least diminished by the fact that this work shows certain traces of cursoriness and disequilibriousness, as well as a certain want of continuity and well-ponderedness. These features are mostly inherent to all pioneer work and the author himself states in the preface, that this work is meant as a provisional publication; this is in accordance with the title, which, by the way, could have been more adequately chosen, e. g.: Materials to Malaysian Phytogeography („Maleische” is, in my opinion, in Dutch a less felicitous word). Indeed, this paper contains a great many informations and stimulating ideas, and moreover, an almost complete bibliography, also of many papers in Dutch. It may be supposed indeed that there is, at present, hardly any other botanist available who is more capable than VAN STEENIS to continue this work and to prepare, some time, a complete „Phytogeography of Malaysia”, to which we are looking forward with great interest.

    A note on Heterophylly and Branching patterns in the Amyema complex (Loranthaceae) (1980)

    Description: Attention is drawn to the unusual distribution of flowers and inflorescences in a number of species, and to certain peculiarities of branching and phyllotaxy. The latter are explained by a heterophylly which so far has escaped notice, involving the formation and early disappearance of a pair of minute intercalary cataphylls. A similar branching pattern and flower distribution is evident in Helicanthes.

    Description: Dr. C. A. BACKER, Verklarend Woordcnboek van wetenschappelijke plantennamen (Explanatory dictionary of scientific plantnames) — Noordhoff-Kolff, Groningen-Batavia, 1936 — XII + 664 — Price: flh. 19.50. Many botanists and also sylvi-, liorti- and agriculturists and almost all taxonomists are, in the course of their daily task, meeting plant-names, the exact meaning, signification or derivation of which is not immediately clear to them. Being an intelligent and studious man, he often feels the desire to know more of a name than just its orthography and so he makes a grab at one of those books written to spread more knowledge about the matter. If it is the name of a genus or of a subgenus, WITTSTEIN’S „IIandwörterbuch” is the book he needs, although it yields no help for genera younger than 1852 (date of preface). If it is a specific name or a latin or latinized botanical term, BISCHOFF is his man, either by his „Handbuch der botanischen Terminologie” of 1833—1844 or by his smaller „Wörterbuch der beschreibenden Botanik”, of 1857 (2nd Ed.). In case these books cannot meet his wishes, on account of their age or merely out of deficiency, our present-day investigator will try to find the name in one of the more recent lists: BAILEY’S „Companion for the Queensland student of plant life” of 1893; SALOMON-SCHELLE, Worterbuch der botanischen Kunstsprache, 1904; KANNGIESSER, Etymologie der Phanerogamen-Nomenclatur, 1908 (mainly generic names); Voss, Botanisches Hilfs- und Wörterbuch (6th ed. 1922), etc.

    Four frequently confused species of Typhonium Schott (Araceae) (1981)

    Description: Typhonium trilobatum, T. flagelliforme, T. roxburghii, and T. blumei are taxonomically distinct, but their epithets (including that of T. divaricatum, nom. illegit.) frequently have been interchanged, primarily because of nomenclatural problems involving synonymy and (mis)typifications. It is concluded that the last monographer (Engler, 1920) used the correct names for the four species, except for what he called T. divaricatum, here called T. blumei.

    Description: Beside Saraca celebica from Celebes, presently a second species from East Malesia is described. As based on the revison by Zuyderhoudt (Blumea 15, 1967: 413 – 425), with 8 accepted species, there are now 9 species of Saraca, ranging from India and Indo-China into Malesia east to the Lesser Sunda I. (Flores) and the Moluccas (Halmaheira). The new species, Saraca monadelpha, was initially recognized through a specimen from Halmaheira which was difficult to determine as a Saracca because of its deviating partly fused stamens and its origin beyond the known area of the genus. Of S. celebica the pods were not known until recently collected in Central Celebes The fruits of S. monadelpha are still unknown.

    Details
    Publication Date: 2014-10-27
    Description: In this report narcotisation, fixation and preservation experiments with marine zooplankton are described. Narcotisation turns out to be useless for mixed plankton samples. M.S. 222 works well as narcotisation medium for organisms to be photographed. Fixation with 4% formalin proved to be a necessary treatment. Afterwards the best preservation method is to use a propylene phenoxetol plus propylene glycol solution in distilled water or a 2% formalin solution in filtered seawater. Further study is necessary of the use of sea-water as a solution medium, of the pH changes, the osmotic value of the solutions, the longterm use and the subsequent processability of the organisms for histological purposes.

    Marine sponges from Curaçao and other Caribbean localities Part II. Haplosclerida (1980)
    In:  Studies on the Fauna of Curaçao and other Caribbean Islands (0166-5189) vol.62 (1980) nr.1 p.1

    Publication Date: 2014-10-27
    Description: The present paper deals with the West Indian marine Haplosclerida incorporated in the collections of the Zoological Museum of Amsterdam. A total of 36 species is described and fully illustrated. Part of the material consists of the Duchassaing & Michelotti collection housed in Amsterdam; of all the Haplosclerid types of this collection an extensive redescription and a photographic illustration is given. Most of the type specimens are designated (para-)lectotypes. Eight new species are erected, viz. Reniera curaçaoensis, R. carmabi, Sigmadocia piscaderaensis, Niphates alba, Xestospongia wiedenmayeri, X. portoricensis, Petrosia weinbergi, and Strongylophora hartmani. The follwing new combinations are used: Niphates amorpha (for N. digitalis forma amorpha Wiedenmayer, 1977), Cribrochalina spiculosa (for Siphonochalina spiculosa Dendy, 1887), Pellina nodosa (for Phloeodictyon nodosum George & Wilson, 1919), and Pachypellina podatypa (for Haliclona podatypa De Laubenfels, 1934). Several new combinations are suggested for species not represented in the present collection, but studied for comparative reasons. A new classification of marine Haplosclerid families is proposed, based on the study of the present collection, and on the study of many type species of Haplosclerid genera. The new classification comprises five families, viz. Haliclonidae, Niphatidae (n.), Callyspongiidae, Petrosiidae (n.) and Oceanapiidae (n.). The proposed classification is discussed and some phylogenetic ideas are presented. The zoogeography of the West Indian sponges is studied and some ecological data are given.
