Description: The aim of this book is to provide all persons interested in the tree and wood species of Suriname with a simple means to find the name of a given tree. To this end two dichotomous keys have been drawn up with the help of punched cards prepared from studies of conserved material and field observations made by the authors. The first one makes use only of vegetative characters of leaves and twigs and a few saliant features of the bark, disregarding flower and fruit characters mostly used in floras. The second key is based on the anatomy of the wood as far as this can be observed with a good 10 X or sometimes 20 X magnifying hand-lens.\nIn the \xe2\x80\x9cInleiding\xe2\x80\x9d the terminology applied in each of the keys and in the descriptions is explained and elucidated by sketch drawings. After the keys follows the descriptive part in which the families are treated in alphabetical sequence as are the genera within each family and species within a genus. In general the taxa are taken in the same circumscription as in the \xe2\x80\x9cFlora of Suriname\xe2\x80\x9d; where a different name is accepted, following recent views, the name in the Flora has been added in brackets. Attention is drawn to the Mimosaceae and Papilionaceae which are treated here on account of their close relationship as two major subdivisions of Leguminosae, the latter name being used as general family heading.

Description: Die Subsubclassis Redioinei ODENING, 1960 innerhalb der Unterklasse Digenea (VAN BENEDEN, 1858) wurde in zwei fr\xc3\xbcheren programmatischen Systementw\xc3\xbcrfen provisorisch, teilweise in Anlehnung an LA RUE (1957), gegliedert (ODENING 1960, 1961b). Ich halte es heute f\xc3\xbcr angebracht, die in jeder Beziehung bestimmbaren und festumrissenen Trematodengruppen als Ordnungen zu bewerten, wie es z.B. auch in den neueren Systemen der Cestoden der Fall ist. Diese Auffassung hat nicht nur praktische Vorz\xc3\xbcge, sondern sie befreit auch die unbestritten einheitlichen Gruppen aus hypothetischen Verbindungen. Ist es doch ein Nachteil der meisten neueren Einteilungsversuche der Digenea, da\xc3\x9f phylogenetische Hypothesen in Form von Ordnungen etabliert wurden, die nach Lage der Dinge je nach Auffassung der Autoren recht verschieden zusammengesetzt waren, w\xc3\xa4hrend die wirklich einheitlichen Gruppen mit den Zwischenkategorien (Unterordnung, \xc3\x9cberfamilie) bedacht wurden. Die Redioinei umfassen nach der neuen Wertung folgende selbst\xc3\xa4ndige Ordnungen (alphabetische Reihenfolge): 1. Allocreadiida Odening, 1960 2. Azygiida (La Rue, 1957) stat. et nom. emend. 3. Clinostomatida (Allison, 1943) stat. et nom. emend. 4. Cyclocoelida (La Rue, 1957) stat. et nom. emend. 5. Fasciolida (Poche, 1926) stat. et char. emend. 6. Hemiurida (Poche, 1926) stat. emend. 7. Opisthorchiida (La Rue, 1957) char. emend. 8. Paramphistomatida (Poche, 1926) stat. et char. emend.\nDie Ordnung Didymozoida (Poche, 1926) ist von den Redioinei auszuschlie\xc3\x9fen, da sie m\xc3\xb6glicherweise nicht zu den Digenea geh\xc3\xb6rt (siehe Baer & Joyeux 1961).

Description: We present below listings of mycotic infections occurring in vertebrates at the Chicago Zoological Park from September, 1954 to December, 1962. Most of the identifications were made by Dr. Tilden and Mrs. Getty from cultures of the fungi involved. Except for a few cases noted among the mammals, the findings were made from necropsy material.\nIt is interesting to note the wide variety and numbers of birds with mycotic infections in contrast to the few findings in mammals and reptiles. Our interest in mycotic infections during this period led to the publication of the eight articles listed at the end of this paper, and the reader is referred to these for additional information on some of the cases. These studies have included research on the endotoxins of Aspergillus flavus and fumigatus, the description of a new species of Microsporum, and case reports of mycoses in animals that were previously unrecorded.

Description: The bacteriological examinations of abnormal stools, irrespective of the apparent seriousness of the illness, is particularly important in a zoological park where it is difficult to apply measures to keep out possibly infected wild, non-resident animals and mechanical carriers, such as flies, cockroaches, etc. One obvious instance of the initiation of an epidemic by nonresident animals was the occurrence of infection with Salmonella newport among the animals in the pachyderm house. The first case in an elephant occurred about a month after S. newport had been isolated from the blood of a skunk found dead in the park. Prompt diagnosis of the first case and examination of the stools of other animals in the same building led to the discovery of further infections before symptoms occurred in the other animals. Suitable antibiotic therapy was instituted, but the first animal, an adult female elephant, was lost. All the pathogenic enteric bacteria isolated were identified as S. newport.\xc2\xb9) A fatal infection of a young forest horse with Salmonella typhimurium occurred following a long period of rainy weather leading to standing water in the enclosure. Contamination of the water by wild rats is believed to have been the most likely source of infection in this instance. No secondary cases occurred.

Description: Monoecious, marsh or aquatic plants, with perennial, creeping rootstocks and erect, terete stems. Leaves alternate, linear or strap-shaped, sheathing at the base, flat, slightly convex on the back. Flowers unisexual, densely crowded in simple, compact, cylindric spikes. Male inflorescence terminal and separated from the female spike or contiguous to it; each spike subtended by spathaceous, usually fugacious, bracts and divided at intervals by smaller caducous bracts. Perianth consisting of bristles. Male flowers with 3, rarely 1\xe2\x80\x947 stamens; the filaments free or connate; the anthers linear or oblong, basifixed, 2-celled, with longitudinal dehiscence; the connective produced beyond the cells in a conical, carnose acumen; pollen grains simple or compound. Female flowers with a one-celled, superior, stipitate and fusiform ovary; the ovule solitary and anatropous; the style elongate, slender, erect; the stigma ligulate, spathulate, lanceolate or linear. Among the female flowers many sterile ones with clavate tips. Fruit minute, stipitate, fusiform or ellipsoid, with a membranaceous or coriaceous pericarp, splitting longitudinally. Seed subcylindric or narrowly ellipsoid; the testa membranaceous; albumen farinaceous. Embryo cylindric, straight. About 8 species in one genus, widely distributed in temperate and tropical regions.

Description: Annual or perennial herbs, rarely shrubby. Leaves alternate, consisting of sheath, ligule and blade. Sheaths envelopping the stem, usually with free margins; ligule borne at the mouth of the sheath, membranaceous or a rim of hairs; blades mostly elongate, flat, convolute or terete, parallel-veined. Inflorescence spicate, racemose or paniculate, bearing spikelets which consist of a shortened axis (rhachilla) and two to many scales. The two lowest scales (glumes) empty, rarely wanting; the following scales (lemmas) bearing in their axil an usually enclosed prophyll (palea) and a perfect or reduced flower. Lemma, palea and flower together forming the floret. Perfect flower consisting of 2\xe2\x80\x943 hyaline or fleshy lodicules, usually 3 (1\xe2\x80\x946) stamens and a pistil. Stamens with at anthesis rapidly elongating, filiform or ribbon-like filaments with 2-celled anthers, opening with longitudinal splits. Ovary superior, 1-celled; ovule one, anatropous; styles usually 2(1\xe2\x80\x943) with plumose stigmas. Fruit a caryopsis (i.e. the pericarp adnate to the seed) with mealy endosperm, rarely a nut, a berry or an utricle with free pericarp. Embryo small, at the base of the side opposite the hilus. About 4000 species in 500 genera; of world-wide distribution.

Description: There is a great diversity of opinion regarding the interpretation of the genera and some species in the former Hippocrateaceae. If one reads the comprehensive and detailed revision of the New World Hippocrateaceae by A. C. Smith (Brittonia 3, 1940, 341\xe2\x80\x94555), one may have an impression of it. For example, A. C. Smith in his monotypic genus Hemiangium, under H. excelsum, has united species which were recognized as belonging to three different genera by Miers; he has also limited Hippocratea L. to a single species, H. volubilis L., and placed more than 40 names of species and varieties in the synonymy of it.\nA detailed review of the history and generic delimitation of the family Hippocrateaceae has already ably been summarized and discussed by A. C. Smith in the above mentioned publication. I shall make only a brief account of those works which contain genera, species, or discussions related to the Malaysian flora.

Description: In 1962 Microthamnion strictissimum Rabenhorst was found twice in the Netherlands, whereas it had not been recorded before from that country. It was collected in a shallow oligotrophic pool (Leersumse Veld, Eerste Plas, prov. Utrecht) as well as in an also shallow but eutrophic one (Herenvennen, Bergen, prov. Limburg).

Description: Tetramyxa parasitica Goebel. In Gorteria 1, no. 12, 1963, p. 138 vermeldt C. den Hartog deze, gallen op Ruppia veroorzakende, schimmel voor de eerste maal voor ons land, en wel van enige inlagen op Schouwen en Noord-Beveland. Bij het doorzien van het Ruppia-materiaal van het Rijksherbarium en de Kon. Ned. Botanische Vereniging bleek, dat zich in laatstgenoemde collectie een plant van Ruppia maritima met Tetramyxa-gallen bevindt, verzameld in 1868 door F. Holkema \xe2\x80\x9ein een oude doorbraak in de Kuil op Texel\xe2\x80\x9d. v. O. en R.\nErica scoparia L. nu ook op Texel. Door de heer W. A. Luynenberg werd, samen met de heer G. J. de Haan en op diens aanwijzing, op Texel aan de Hoornse Slag op 27 augustus 1963 materiaal verzameld van bovengenoemde soort, die daar in een tweetal exemplaren voorkomt. De planten groeiden op enigszins gestoord terrein. Ook hier is het weer, evenals op Terschelling, voorlopig onmogelijk een bevredigende verklaring van het voorkomen te geven; het wordt er alleen maar nog raadselachtiger door. v. O. en R.

Description: This paper deals with the habitat of Cornus suecica in pine and spruce plantations near Wilhelmshaven (N.W. Germany), one of its southernmost localities in Europe. The table of records represents a transect from open pinewood to a dense, mixed pine-spruce-wood. All the shrubs, as well as the herbs and bryophytes of groups 1 obviously prefer the light wood stand, whereas those of groups 2 and especially 3 are most abundant and fertile in dense shade.\nCornus suecica and Trientalis europaea show an opposite behaviour with regard to light, and so do the two closely allied Dryopteris species, D. austriaca and D. spinulosa.
