Description: Twelve species of terricolous microlichens from the Angmagssalik District, Southeast Greenland, are reported: Caloplaca friesii, C. livida, Lecanora boligera, Lecidea oligotropha and Leciophysma arctophila, which are new to the lichen flora of Greenland, Rinodina conradi, which is new to the eastcoast, and Baeomyces roseus, B. rufus, Buellia geophila, B. punctata, Caloplaca tornoensis and Mycoblastus tornoensis, new to Southeast Greenland. In a discussion of the greenlandic distribution, unpublished records from the herbarium of Copenhagen (C) are incorporated. Notes on the habitats are given and the pertinent phytosociological units indicated. Some morphological and anatomical characters are commented upon briefly.

Description: The 16 recognized species of Sorocea are listed with their synonyms and distribution. Two new taxa are described: S. steinbachii C.C. Berg and S. hirtella Mildbread ssp. oligotricha Akkermans & Berg. Three new combinations are made: S. muriculata Miquel ssp. uaupensis (Baillon) C.C. Berg, S. trophoides W. Burger ssp. rhodorachis (Cuatrecasas) C.C. Berg, and S. sprucei (Baillon) Macbride ssp. saxicola (Hassler) C.C. Berg. A key to the species is presented.

Description: Some rain and savanna forests of western Suriname (Corantijn R., Winana Creek; Upper Marataka R.; Upper Nickerie R;) were studied and their composition was compared with that of forests of other parts of Suriname and Guyana. The savanna forests of western Suriname proved to be much related to Guyanan ( Walabaand Dakama-) savanna forests as described by Davis & Richards (1934) and Fanshawe (1952). On the other hand, there was less relationship as regards rain forests of western Suriname when compared with ones of Guyana and other parts of Suriname, except for the Demerara greenheart forest of the Upper Marataka R., which was closely related to the Demerara greenheart forests of Guyana as described by Davis & Richards (1934). In addition an upland rain forest was studied near Blanche Marie falls, Upper Nickerie R., which proved to be very much like that of the Stofbroekoe Mts., eastern Suriname, as described by Schils (1960). Species/area curves for some rain and savanna forests are given. The geographical distribution of some common western Surinam tree species was studied; of the seventeen species studied one was endemic for Suriname. An annotated list of all species of trees and palms occurring in the explored areas is provided.

Description: The species Polypodium banaense C.Chr. is transferred to Crypsinus. The recognition of a genus Phymatopteris Pic. Ser. (= Phymatopsis J.Sm.) separate from Crypsinus is discussed.

Description: The six species of Curtia, including a hitherto undescribed species published here, as well as the monotypic genus Hockinia can be distinguished from each other by the seed coat structure. The anticlinal walls and the cuticle provide the most useful information. Curtia tenuifolia appears to be a complex species, but subsp. tenella can be readily separated from this complex by the seed coat structure. Heterostyly has been found in C. tenuifolia subsp. tenuifolia, C. obtusifolia, and Hockinia montana, but differences in seed coat structure can not be correlated with long-, short-, and equal-styled flowers. The differences in seed coat structure, the length of the seeds, and the number of cells per seed plead for maintaining Hockinia (closely related to Curtia) as a distinct genus. One new species of Curtia is described and a new combination is made.

Description: SETTEN, A. K. van & KOEK-NOORMAN, J.: Studies in Annonaceae. VI. A leafanatomical survey of genera of Annonaceae in the Neotropics. — Bot. Jahrb. Syst. 108: 17—50. 1986. — ISSN 0006-8152. Within the scope of the multidisciplinary research project on systematics of Annonaceae, a survey of the leafanatomical features and their distribution in the neotropical Annonaceae is presented. The studied specimens form a rather homogeneous group, as may appear from the family description given here. A detailed study of the leafanatomical features reveals, that differences are mainly found in the indument, the position and contents of the idioblasts, the structure of the primary vein, the type of crystals in the epidermal cells, and the type of sclereids. Based on character states, phenetic similarities and differences are discussed and compared with the classifications of FRIES (1959) and WALKER (1971).

Description: One new species of Dorstenia from Brazil is described: D. carautae C.C. Berg, and four new combinations are made: D. cayapia Vellozo subsp. asaroides (Hooker) C.C. Berg, D. cayapia Vellozo subsp. paraguariensis (Hassler) C.C. Berg, D. cayapia Vellozo subsp. vitifolia (Gardner) C.C. Berg, and D. ramosa (Desvaux) Carauta, Valente & Sucre subsp. dolichocaula (Pilger) C.C. Berg. A list of and a key to the 22 Dorstenia species distinguished in south-eastern tropical America are presented, together with synonymy and distributional data.

Description: The samples of the genus Calypogeia in the dutch institutional herbaria and private collections, those of C. arguta excluded, have been re-identified, according to the revision of the Swiss Calypogeias by Bischler (1957); distribution maps are given for all the taxa. More exact circumscriptions are given of several differentiating characters which were already established by previous authors. In C. fissa and C. sphagnicola the areolation of the leaves appeared to be a new differentiating character: in C. fissa the cells in the middle of the leaf show a great variation in length, whereas in C. sphagnicola the cell size is uniform. These differences are shown in histograms. C. muelleriana appeared to be restricted to the diluvial parts of the country, whereas C. fissa is common on both alluvium and diluvium; c. neesiana, C. sphagnicola and C. trichomanis are very rare, so that no clear geographical distribution can be given.

Description: Recently a multidisciplinary investigation program on the systematics of Annonaceae was started at Utrecht with special emphasis on the Neotropics. This project will be carried out largely within the framework of the UNESCO-project Flora Neotronica. The first goal is to provide a modern classification of the family as a whole, the second is the publication of a series of monographs for Flora Neotropica. The project has been planned and started in close consultation with leading botanists on the Neotropical flora. The Annonaceae are a family of pantropical distribution with between 2000 and 2500 species in ca. 130 genera as presently understood. In the Neotropics the family is represented by ca. 750 species and 35 genera. It is a family of trees, shrubs, and lianas. Its place is within the order of the Magnoliales and its supposedly closest relative is the family of the Myristicaceae. The Annonaceae, although generally considered primitive in many features, nevertheless offer a number of specialized features as well This makes it a promising object using various kinds of comparative morphological, karyological, and anatomical data. Besides, many species are of medicinal or commercial value, such as various species of Annona and Rollinia, the fruits of which are commonly eaten in most countries of Central America and South America; the Soursop (Annona muricata) is widely cultivated throughout the tropics.

Description: A new species of Asterophorum, A. mennegae, is described from the Sipaliwini Savanne (Suriname). The position of Asterophorum within the family is briefly reviewed, and a key to the 2 species is given.

Description: Dalbergia and Machaerium are two distinct genera. The former genus Ecastophyllum is a distinct entity in the genus Dalbergia. The former genus Drepanocarpus differs from Machaerium only in certain pod characters and is considered as congeneric with it.

Description: The wood and leaf anatomy of representatives of the 9 genera of the Opiliaceae are described in detail. It is possible to separate the genera on the base of both wood- and leaf anatomical characters. Herein the presence of cystoliths of varying shape and size is important. Some comments on the taxonomy and possible phylogeny of the familiy are given.

Description: In his introductory statements to 'The Symposium on the Phylogeny and Classification of the Filicopsida' which was held in London, 1972, HOLTTUM, when dealing with 'dubious groups of relationships which would particularly repay investigation', mentioned the Polypodiaceae first (HOLTTUM, 1973: 6). Talking about Polypodiaceae the present authors deal with the Polypodiaceae sensu stricto only, thus excluding the Cheiropleuriaceae, Dipteridaceae, Grammitidaceae, and also the Loxogrammaceae, taxa which were formerly (or are still) included in the Polypodiaceae sensu lato. As delineated in this way, this almost exclusively pantropical family consists of about 600 species and an indefinite number of genera.

Description: The new species Coussapoa manuënsis C.C. Berg is described.

Description: The present paper, the fifth¹) in this series, is a continuation of the documented list of chromosome numbers of Angiospermae occurring in the Netherlands. In this paper 49 species and two hybrids are listed. Some species show variation in chromosome number, as was concluded after comparison of our results with those of other authors [cf. the lists published by Löve and Löve (1961); Cave et al. (1956-1964); Ornduff (1967, 1968, 1969); Solbrig and Gadella (1970); Moore (1970)]. Some notes on 14 species and two hybrids are given.

Description: The circular which was enclosed in Bulletin 24 has received full attention of our readers and a large number of cards were received. The large majority favours the continuation of our annotated bibliography as it is, not cutting off references on the Australian and Pacific floras, and not discarding the references on the Cryptogams. A review of Mr. Ferguson’s Index is given on p. 1912. October 21, 1970, Foundation Flora Malesiana existed twenty years. This anniversary was marked by a small festivity in the Rijksherbarium. Although curtailed financially since January 1958, it has kept its promise to promote all studies encompassing progress of the botany and plant geography of the Malesian subcontinent. It is gratifying that with the distinct tendency of the rehabilitation of the economical and political situation in Indonesia during the last few years, science in general, and biology in particular, are getting a new impetus. Amongst others through international agreement and co-operation, two master organisations have been set up, SEAMEC and BIOTROP, the latter being the centre of biological studies and education allotted to Bogor. It is clear that this focus will be a great stimulant and will sponsor biological activity. It was particularly pleasant to learn from Professor Sarwono and Dr. Didin, chairman and secretary of LIPI respectively, that this general scientific rehabilitation scheme included assistance towards the Flora Malesiana Foundation. Although the scientific elaboration of Flora Malesiana has been transferred as a major work project to the Rijksherbarium, a necessity since 1958, there are various desiderata left, amongst others contributions from Indonesian systematists. Unfortunately, the net result of Dr. Kostermans’s efforts to have promising Indonesian students thoroughly trained and prepared to share the tremendous task still before us, is meagre. Two of them, Dr. Soegeng and Dr. Didin, are occupied with very responsible and very necessary but largely administrative tasks, Dr. Prijanto died unexpectedly, and Dr. Soepadmo spends his time largely on educational matters. Clearly something must be done and we trust that in the near future creative work by Indonesian systematists can be resumed. We shall, I sincerely hope, overcome, and the future carries certainly very promising features for a more intense co-operation. And disinterested loyal co-operation is the very basis of ensuring achievement. It is with immense satisfaction that I see this perspective of a bright future ahead.

Description: The entries have been split into five categories: a) Algae – b) Fungi & lichenes – c) Bryophytes – d) Pteridophytes – e) Spermatophytes & General subjects. — Books have been marked with an asterisk.

Description: IUCN, says the paper Categories, Objectives and Criteria for Protected Areas, ”is dedicated to the wise use of the Earth’s natural resources and to the maintenance of the Planet’s natural diversity.” What to think of the sequence? Use first, maintain second? And this comes from the International Union for the Conservation of Nature and Natural Resources? ”The World National Parks Congress, taking place in Bali, Indonesia, October 11-22, 1982, will provide case studies from around the world to illustrate how the various categories of protected areas are meeting the needs of countries of all economic, social, cultural, and political backgrounds,” writes J.A. McNeely, the secretary of the Commission on National Parks and Protected Areas, in a special issue of the Swedish journal Ambio (11: 237. 1982). ”No longer just playgrounds for vacationers and means for conserving natural heritage, protected areas have become an inseparable part of the modern human ecosystem.”

Description: Mrs. Delia D. Adefuin, Museum Research Assistant, Manila, is pursuing her M.S. in Botany degree. She is currently the Secretary of the Fern Society of the Philippines. She is working on the Fern Flora of Metro Manila and is preparing the manuscript of a pictorial encyclopedia which will include descriptions of species and horticultural recommendations. Miss Barbro Axelius (S) collected and studied Xanthophytum and Lerchea (Rubiaceae) in Sarawak, Kalimantan and Sumatra, August 1982- February 1983.

Description: Tropical Botany in Aberdeen University. This was started by Professor J.W.H. Trail, who held the chair from 1877 to 1919, and travelled in the Amazon Valley (1873-75) mainly collecting cryptogams and studying palms. He was succeeded by Prof. W.G. Craib (1920-33) who was never in the tropics but devoted his work to the Flora of Siam, based on the collections of A.F.G. Kerr, and assisted by Miss E.C. Barnett. After a considerable lag, tropical botany was revived by the energetic efforts of Dr. P. Ashton as lecturer in systematics and ecology of the eastern tropics, establishing ties with Malayan colleges in teaching and research. This is at present perpetuated by two lecturers, Dr. K. Jong and Dr. M.D. Swaine, the latter’s experience lying largely in the tropics of West Africa. In addition Dr. N.M. Pritchard, Dr. J.B. Kenworthy and Dr. G. Hadley have been on secondment to the University of Malaya, while Dr. I. Alexander made research visits to India, Ghana and Peru. Over the years the Department has provided undergraduate and research training to innumerable students from many different tropical countries, some of which attained responsible posts, e.g. Prof. E. Soepadmo. Important courses in tropical biology are given, not available elsewhere in the U.K. (started 1973). The benefits for Aberdeen students is important: amongst others they led to expeditions to various parts of the tropics, recently to Sabah and to the Ivory Coast. Royal Society Tropical Rain Forest Collaborative Research Programme. Arising out of a feasibility study by Dr. T.C. Whitmore and P.F. Cockburn, the theme ’Recovery of tropical rain forest after disturbance’ was adopted as the initial basis of the programme. Possible territories for the research include Sabah and the Philippines. Detailed plans for a 5-year project are being prepared in consultation with colleagues in Southeast Asia.

Description: It is with the utmost regret that we announce the sudden and quite unexpected death of Dr. Marius Jacobs, editor of this Bulletin. See the obituary on page 3869. He was co-editor of the Flora Malesiana Bulletin for nr. 17 (1962) to nr. 22 (1968) and took full responsibility onwards of nr. 27 (1974). He showed great ability in enlarging its scope and we have many letters in our archives expressing appreciation and admiration for the lively and informative style in which he edited the Bulletin. I had to take over the editorial work for this number at short notice, but I was greatly helped by a number of Rijksherbarium colleagues, which help is gratefully acknowledged. In this way the delay has been kept to a minimum. It is, however, possible that some news items etc. have not been printed and that information submitted to Dr. Jacobs has not been entered due to this sudden change of editorship. I offer my apologies if this has happened and hope that (if still relevant) the news will again be forwarded to the new editor, Dr. J.F. Veldkamp, Rijksherbarium, who will take over starting next number.

Description: The ultrastructure of the spore walls of Beenakia dacostae (Beenakiaceae, Gomphales) has been studied. Spore walls are mainly composed of a distinct episporium and a thick, dark, ornamented ectosporium. The general structure is identical with that of other members of the Gomphales, such as Gomphus and Ramaria

Description: De in Nederland waargenomen soorten van Taraxacum uit de sectie Spectabilia Dahlst. zijn: T. anglicum Dahlst., T. euryphyllum (Dahlst.) Christ., T. hygrophilum v. S., T. johannis-jansenii v. S. en T. nordstedii Dahlst. Op de kaartjes is hun verspreiding weergegeven, in hoofdzaak berustend op gegevens van na 1950 (fig. 1, a—d). Zou men de oudere gegevens daaruit weglaten, zo zou het beeld dat de kaartjes bieden niet noemenswaard worden beïnvloed. Bij de steeds verder schrijdende cultuurmaatregelen worden deze, op natuurlijke standplaatsen groeiende soorten ernstig bedreigd. Volledigheidshalve zij vermeld dat nog twee nieuwe soorten uit deze sectie te zijner tijd in de Acta Botanica Neerlandica zullen worden gepubliceerd: T. duvigneaudii v. S. (Gouda-Waddinxveen) en T. zevenbergend v. S. (Hijzen bij Moergestel en Houtakker bij Tilburg).

Description: In 1960 I made a preliminary analysis of the floristic distribution of the native Phanerogam genera of the Pacific islands, which amounted to 1511 genera in all. The aims of the present work have been to record these more accurately and more critically in detail, especially with regard to native versus introduced, to complete the survey with new records from new explorations made during the interval, and to evaluate new taxonomic literature on Pacific genera. The present list amounts to a total of 1666 genera, as far as known in July 1969, listed in an Appendix. The floristic relationships of the Pacific islands and the surrounding continental areas are established and a hierarchical subdivision of the flora of the Pacific islands based on demarcations in it is made. Furthermore a nomenclatural stabilization of the names and ranks of the subdivisions is attempted. Chapter IV, 3. An attempt was also made to find factual data on the correlation between distribution and means of dispersal. Chapter IV, 4. Secondary aims were to review earlier attemps towards a subdivision of the Pacific flora (Chapter II), two other secondary purposes to see whether traces of the historic plant-geography of the Pacific flora are still reflected in the present flora (Chapter V), and finally to compare geographic subdivisions and other data from non-Phanerogam taxa, mostly animals, with floristics. Chapter VI. Chapter III is devoted to an explanation and a discussion of the methods employed. Arguments are given why only Phanerogams have been considered and why only native genera have been used for computing results. Chapter III, 1—2. Arguments are given for employing the genus as a working unit. It is shown that the genus is much less susceptible to variability in taxonomic concepts than either the species or the family. Besides it is comparatively easy to establish the distribution of a genus fairly reasonably from literature. Chapter III, 3. Chapter III, 4 is devoted to a discussion on the sources of information on which this work is based, comprising i.a. literature, herbarium collections and personal information. Many errors are contained in the first two of these and it cannot be avoided that some mistakes have not been detected. Also, the island groups have been investigated with a varying degree of intensity. The island groups in the Pacific are taken as geographic units of which there are 36. The surrounding land masses are divided into 12 main areas. Chapter III, 5. Of each genus occurring in any of the 36 Pacific unit areas the full distribution is traced. See Appendix. From a comparative study of generic ranges, it has appeared that they exhibit a restricted number of recognizable patterns, 17 of which have been distinguished. These I have called distribution types in this work. Chapter III, 6. The choice of geographic unit areas introduces a certain element of arbitrariness. Each island group can then be characterized by its set of distribution types: the distribution types spectra. It is also possible to calculate floristic relationships or resemblance between the island groups, for which a number of methods are discussed and evaluated. It appears that basically all methods lead to more or less similar conclusions. Chapter III, 9. As a test for the validity of the conclusions based on the distribution of all genera, similar calculations were performed on 345 revised or otherwise well-known taxa. Although the percentages of the distribution types are slightly different the general conclusions are corroborated. Chapter III, 7. In addition, an attempt has been made to find whether there is a correlation between the distribution and the means of dispersal of these revised or otherwise well-known taxa. Chapter III, 8. One of the most important results of this work is the census of Pacific genera. See Appendix. By using the method of distribution types spectra, demarcation knots and other methods it has been possible to find demarcations and to define phytochores. The main demarcation is that between the New and Old World floras. A hierarchy is set up of subdivisions which is illustrated in fig. 35 and tabulated in table 6. It appears that a strong demarcation exists between the islands on the American side of the Pacific (Galapagos, Juan Fernandez, etc.) and the western islands. Hawaii and SE. Polynesia form the easternmost frontier of the OldWorld flora. This conclusion was reached almost unanimously by all phytogeographers, one of the earliest being Engler after whom I have proposed to name this demarcation: Engler’s line. In the W. Pacific Bonin in the north and New Zealand and adjacent islands in the south show a sharp demarcation from the rest, Bonin forming part of the E. Asiatic region, and New Zealand forming a distinct subregion of the Australian. New Caledonia cannot be satisfactorily placed. It shows relations with New Guinea, Queensland and the Pacific in about equal measure. Besides it abounds in endemics, some of which are highly peculiar in various aspects. The remaining part of the Pacific shows an essentially Malesian character, decreasing in strength from west to east. The New Hebrides with Fiji, Samoa and Tonga form a subprovince as does SE. Polynesia, Hawaii is considered a separate province of the Malesian subregion. Unlike the islands west of Engler’s line the American Pacific islands show very little mutual floristic alliance, but they all have a characteristic American flora. Comparisons with subdivisions and demarcations of other groups of organisms show that often, but not always, the same barriers are respected by unrelated groups. My data give certain indications about the past but no attempt has been made to correlate the conclusions with contemporary geological theories. The regularity of distribution patterns, the close floristic alliance among the islands west of Engler’s line independent of their distance from each other, combined with the fact that dispersal spectra show no clear correlation between distribution and ‘dispersibility’, suggests an old relictual character of the flora rather than a young one built up by random long-distance dispersal. This applies especially to the W. Carolines, the Melanesian islands, Lord Howe I. and New Zealand, i.e. islands more or less within the Andesite line, which are much richer and contain many poor dispersers. For Hawaii also a better accessibility in the past seems indicated. The regular decrease in the number of taxa in proportion to their distance from source areas is discussed. An attempt is made to explain the phenomenon. A tentative conclusion is reached that impoverishment and other phenomena attributed to oceanic islands are not restricted to these. A large scale comparative study of continental and island floras is needed.

Description: In January 1971 Dr. Simon Jan van Ooststroom, senior botanist of the Rijksherbarium, retired on reaching the age of 65, having been on the staff since November 1934. Though this event will to a certain extent change, but not interrupt, his work, it is nevertheless worth commemorating, as he has so many contacts at home and abroad, all of whom have profited from his wide knowledge which he shared freely. He was born in Rotterdam in 1906, where he received his primary and part of his secondary education. He completed the latter in Schiedam and entered the University of Utrecht in 1924. He became the assistant of Prof. Dr. A. Pulle in January 1927. By chance he became interested in the genus Evolvulus and this led him to compose an excellent world monograph of this genus for which he was awarded his doctor’s degree in 1934 and which furthermore caused a life-long interest in the bindweed family, on which he became a most reliable authority, especially for the Indo-Australian region. Many papers emanated from these studies, culminating in his treatment (assisted by Dr. R. D. Hoogland) of the family in Flora Malesiana (1953).

Description: A peculiar structural detail, occurring during the development of ovules, seems to have passed almost unnoticed till the present day. It concerns the distal rim of either the outer or the inner integument, which appears to be slightly lobed in the ovules of several unrelated plants. In a recent note (1970) I called attention to this feature. It is known from Juglans and Platycaria (Warming, 1878; Leroy, 1955; Boesewinkel and Bouman, 1967), where the single integument is two-lobed. Warming mentioned two more cases, namely Lagarosiphon and Symplocarpus; however, I cannot confirm his observations from dried material. I noticed it myself in Scyphostegia horneensis, in Caloncoba welwitschii, and in Sterculia alexandri. In these three species the lobes occur at the rim of the outer integument. To these can now be added Hernandia peltata. However, in that species the lobes occur at the rim of the inner integument.

Description: In Malesia the genus Tephrosia is represented by 20 species, native or introduced and naturalized, including 6 subspecies and 5 varieties; 4 species are restricted to Malesia. Two of these species are newly described: T. barbatala and T. elliptica; the former includes one new variety (var. glabra). Two new subspecies and one new variety are distinguished: T. filipes subsp. longifolia, T. purpurea subsp. barbigera, and T. maculata var. elongata. Two taxa are given a new status: T. maculata var. appressepilosa and T. pumila subsp. aldabrensis. Four species, T. dichotoma, T. repentina, T. coarctata, and Kiesera sumatrana are for the first time sunk into synonymy. A key to the taxa, synonymy, and full descriptions with plates and distribution maps are given.

Description: During identification and study of the materials of the genus Blepharis Juss. in the Central National Herbarium (CAL) of the Botanical Survey of India the authors came across some specimens (Lawson 314) from Tavancore, which was identified as B. molluginifolia aff But critical study revealed that the typical molluginifolia is a different species from which the new taxon can be distinguished by several characters. The species is named after M.A. Lawson who collected the specimen for the first time.

Description: The new scheme of classification presented in this paper is based on the examination of all species in the family Thelypteridaceae which I have been able to trace in the Old World. I have gradually compiled a list of about 700 names (basionyms) and have examined type or other authentic material of all but a small proportion; and in the course of study of specimens in many herbaria I have noted about another 50 species which appear to be undescribed. I have attempted to re-describe all the previously-named species, noting characters not mentioned in existing descriptions, especially the detailed distribution of hairs and glands, including those on the body and stalk of sporangia, and characters of spores. It is probable that there remain some published names, not yet detected by me, which refer to species of the family, but I think there are not many. I have also made a study of all generic and infrageneric names which are typifiable by species of Thelypteridaceae, and in doubtful cases I have tried to clarify and fix the typification. As already reported in the second paper of this series (Blumea 18: 195—215), I have had the help of Dr. U. Sen and Miss N. Mittra in examining anatomical and other microscopic characters of some type species, and hope to present further information of this kind later.

Description: Until now three species of apetalous Hamamelidoideae have been reported from Taiwan (Li, 1963): Distylium gracile Nakai, Distylium racemosum Sieb. & Zucc., and Sycopsis formosana (Kanehira) Kanehira & Hatusima (close to or identical with S. sinensis Oliver). A list of the specimens of the Herbarium of the National Taiwan University, Taipei (TAI), kindly sent by Prof. Ch. E. DeVol (Oct. 3, 1970), contains the same three species.

Description: One new species of Aristolochia, A. singalangensis, from Sumatra is described here. This is the only Malesian species to have the fruit dehiscing from the apex towards the base. Remarks are given for some Asiatic and Malesian species, all belonging to Aristolochia except one to Thottea, on their taxonomy, nomenclature, typification, characteristics for identification, relationship, distribution, etc. The phenomena and significance of aristolochiaceous plants-butterflies relationship have been discussed. Germinated pollen grains have been found in dehisced anthers of open flowers in both Aristolochia and Thottea. Pollination of the Aristolochiaceae has been concisely reviewed.

Description: In April 1969 I paid a visit to Ceylon for a week, allowing me to study for the first time the collections of the Department of Agriculture, Peradeniya (PDA), including Thwaites type specimens. My stay was made possible through the Smithsonian Flora of Ceylon Project. The study of Thwaites’ type material revealed some new facts affecting the synonymy of Ochna jabotapita L. and O. obtusata DC. It had previously come to my attention that materials distributed as O. moonii Thw. under number C.P. 1224 belonged to either O. obtusata (BM, BO) or O. lanceolata Spreng. (K, P) (see also the note on page 26 of my revision). I subsequently found that all three species of Ochna in Ceylon were represented on the sheet in PDA, obviously bearing Thwaites’ holotype. From this and accompanying sheets it is clear that the material belonging to O. jabotapita should in fact be designated as the holotype of Thwaites’ species. Consequently, the whole paragraph under O. moonii on page 30 of my revision should be transferred from the synonymy of O. obtusata to that of O. jabotapita. The phrase ‘excl. syn. O. quarrosa L. sensu Moon = O. jabotapita L. ’should be deleted. The type should be referred to as C.P. 1224 p.p. (PDA p.p. holo).

Description: A massive, expensive book, principally an atlas of small botanical drawings (line drawings, c. 10 by 6 cm, two to a page), each provided with the Latin and vernacular name, a concise 2—4 line descriptive note, and the use of the plant. A similar text is added in Japanese. Most pictures are reproduced at ½ nat. size. Species are arranged alphabetically within the families which are in turn arranged according to the Englerian system. Only Gymnosperms and Angiosperms are included. Prof. Corner is responsible for checking the names and the brief descriptive notes. The pictures were drawn by Prof. Watanabe during World War II for the Japanese Military Administration at the Singapore Botanic Gardens. Two volumes of these drawings were already published in small octavo in 1945 at Singapore, one on Medicinal Plants, the second on Edible Plants. A selection of some 200 plates was also later published by Prof. H. B. Gilliland in his ‘Common Malayan Plants’ in 1958 (University of Malaya Press, Singapore). The present work embraces all pictures made by Prof. Watanabe, many unpublished before, with addition of a number not made at Singapore, amongst them several of rare parasitic and saprophytic species from Borneo and Celebes, Pandanus from New Guinea, and other interesting odds, even from Japan, the Bonins, etc.

Description: There are only two genera of the Aristolochiaceae, Aristolochia and Thottea, so far known to occur in Malesia. In the course of a revision of this family for the Flora Malesiana, some new species of both genera have been found. Eight new ones of Thottea were published in a precursor on that genus (Blumea 27, 1981, 301-332, f. 1-72). There are four new species of Aristolochia from Borneo and one more new Thottea from Sumatra to be described here.

Description: Carpels develop centripetally as oblique slightly ascidiform structures provided with a seat-like support. The terminal mouth of the ascidiform primordium becomes the lateral cleft of the carpel. Solitary terminal carpels develop as lateral structures. The sections Tasmannia and Drimys of the genus Drimys differ by the varying degree of ascidiform development. Austrobaileya is like Drimys. The structure of the carpel margins with submarginal placentation may have evolved from a slit like that in Winteraceae. Allometric development of an oblique ascidiform structure may have formed a large basal ovary, and may thus have moved the stigmatic part apically. A possible cupular origin of carpels is discussed.

Description: A key is given to 7 species, 6 of which occur in Malesia. Of each the basionyms and a restricted synonymy are given, besides notes on their distribution. Rotala diversifolia Koehne, hitherto only known from Thailand, appears to occur in several localities in Malesia. A new combination, R. catholica (Cham. & Schlechtend.) B. van Leeuwen, is proposed for the American R. dentifera (A. Gray) Koehne, introduced in Luzon.

Description: The buthid scorpions of the genus Centruroides are widely distributed in the Antillean area. They are also the most common scorpions in the majority of these islands. Nevertheless they remained almost forgotten until recently (STAHNKE 1970; ARMAS 1976, 1977, 1980, 1981, 1982; FRANCKE & SISSOM 1980). For the purpose of this paper the Lesser Antilles are defined as the islands situated between the Virgin Islands and Trinidad & Tobago, according to BOND’S 1978 zoogeographical point of view.

Description: Although the corals and reefs of Curaçao are fairly well known (VAN DER HORST 1927, Roos 1964, 1967), information about coral growth around the other islands of the Netherlands Antilles is still lacking. This paper offers the first comprehensive study of the reef corals of this area: Aruba, Curaçao (with Klein Curaçao), Bonaire (with Klein Bonaire), St. Martin, Saba and St. Eustatius. Due to practical reasons, however, the survey had to be restricted in several respects.

Description: 1. Cassiopea xamachana is unable to tolerate any wave action, turbulence or currents. 2. Although the species is found only in shallow water where the light intensity is high, it could not be demonstrated that light intensity is an important factor. 3. Normal temperature fluctuations — at least in the Antilles — are of no significance as the range that Cassiopea under laboratory conditions proved to be able to withstand is wider than the fluctuations occurring in their natural environment. On the other hand, after heavy rainfall when the pools are covered with fresh water the bottom water temperature may rise to deleterious levels. 4. The salinity range in the habitat of Cassiopea is from about 33‰ to 54‰. When the regeneration rate is used as a parameter for optimum salinity conditions, supersaline water of about 40‰ is optimal, which is about the average salinity in their natural habitat in Curaçao. In the Dry Tortugas, where the salinity is lower, optimum regeneration occurs at a lower salinity level, as reported by GOLDFARB, 1914.

Description: During the Late Devonian, deposition in the Cantabrian Mountains was largely controlled by movements along faults. By way of intermitting subsidence of the area south of the Sabero-Gordón line and the connected progradation of the coast during the Frasnian and early Famennian, three regressive sequences were deposited. On account of these sequences the Nocedo Formation is divided into three units. Before the late Famennian transgression, after which the upper part of the Ermita Formation was deposited, the area was peneplained. Six facies maps show the changes in palaeogeography during the Late Devonian.

Description: The Lois-Ciguera Formation is a unit of alternating limestones and terrigenous sediments of Lower to Upper Moscovian age in the Cantabrian Mountains of northern Spain. The proportion of limestones is fairly high, 30 to 50% of the total thickness. In the eastern part of the Lois-Ciguera Synclinorium, the formation consists almost exclusively of limestones. One section (LSW) is selected to serve as a model for the depositional and diagenetic textures of the limestones of the entire formation. More than 80% of the limestones appear to be algal-bound. Description and subdivision of these algal boundstones was possible by a modification of the classification scheme of Dunham (1962). The algal boundstones are classified as algal-bound lime mudstones, algal-bound lime wackestones and algal-bound lime packstones. Algal-bound lime wackestones and algal-bound lime packstones appear to be the most important. The first are thought to have been formed on the floor of a quiet lagoon by precipitation of algal micrite in the hairy masses of non-calcareous Algae (pseudostromata bioherms). Among the algal-bound lime packstones, three groups can be distinguished: (1) those formed by intergrowth of calcareous Algae (calcareous Alga bioherms), (2) those representing carbonate sand from littoral or lagoonal settings invaded and bound or agglutinated or entrapped by non-calcareous Algae, (3) those intermediate between groups (1) and (2). The bioherms of calcareous Algae are thought to have formed at a depth ranging between low tide level and ca. 12 m in an environment of variable turbulence. Neomorphism of algal-bound micrite is distinct from neomorphism in mechanically deposited micrite because of the interaction of pore-filling calcite in the originally porous algal micrite sustained by an organic framework. Several generations of pore-filling calcite can be distinguished. Complete filling of the pores with calcite may have occurred during an epidiagenetic interphase during syndiagenesis. There are indications that dolomitization was syndiagenetic. Both the capillary action/evapo-transpiration theory and the theory of a refluxing hypersaline brine may provide explanations which fit the conditions of formation of the LSW dolomitic limestones (dolomite content of 5 volume percent or more). The low dolomite content of 5 volume percent or less of the LSW limestones is explained by neomorphism of the originally high-magnesium algal micrite during cementation. Calcitized dolomite crystals and diagenetic silica are commonly observed together in the LSW limestones. It is shown that silicification is the cause of calcitization of the dolomite crystals. The origin of the diagenetic silica is ascribed to the ability of living algal mats to hold considerable concentrations of silica in solution in their interstitial waters. The silica is precipitated during early burial of the algal-bound sediment and goes into solution again during cementation of the limestones. Reprecipitation of the silica occurs after sharp-edged fracturing. Several phenomena of carbonate solution are described. Void creating solution is confined to limestones supported by an algal framework. At present all original pores and voids in the LSW limestones are filled with calcite and the porosity is low. The sequence of diagenetic changes has been analyzed and summarized separately for LSW limestones with an epidiagenetic interphase during syndiagenesis and those lacking an epidiagenetic interphase.

Description: The area described comprises the SE plunging extension of the anticlinorium of Mondoñedo-Lugo-Sarria and several structural units to the NE of it. The stratigraphy compares with that of neighbouring areas. Certain new observations have been made regarding the west flank of the East Galician-West Asturian miogeosyncline at the end of the Precambrium and during the Early Palaeozoic. Stromatolites or algae played an important part in the formation of carbonate deposits during late Precambrian (Cándana limestone) and Lower Cambrian time (Vegadeo limestone). An imprint, possibly attributable to a specimen belonging to the Precambrian Ediacara fauna, was found in the Cándana Schist Formation. A shallow or relatively high zone existed during that time in the region around Incio. The same general area formed a high again at the end of the Ordovician, causing erosion and a marked disconformity of the Silurian. The Hercynian structures can be explained by assuming roughly WSW-ENE compression and shortening. In the NW of the area this is expressed in the first place by the recumbent folds of the Lugo-Sarria anticlinorium, and in the SE by the narrowness of the steep folds and their slightly changed direction in the general area of Seoane and El Cebrero. Normal crossfaults are related to the folding and the compression. They show locally a deviation in accordance with the direction of shear stress. Horizontal displacement along such faults in an EW direction was probably of little importance. Finally a few observations are given on the occurrence of Pb-Zn ores at the mine of Rubiales.

Description: Species of the heteropod families Carinariidae and Pterotracheidae collected in the Mid North Atlantic Ocean in 1980 have been studied. The distribution of the species is given, as well as the morphological variation. It is concluded that two subspecies of Carinaria lamarcki actually have to be considered distinctly recognisable and sympatric species, to be called C. lamarcki and C. challengeri. The vertical distribution of the heteropods studied proves not to be restricted to the photic zone and diurnal vertical migration occurs among the larger species. The horizontal distribution of the two Carinaria species and of at least two populations of the Pterotrachea species coincides with the southern branch of the North Atlantic Current, while others are restricted to the subtropical waters. Consequently, the present heteropods have to be considered good indicators of water masses and currents.

Description: Moult cycle and morphogenesis in larval instars (zoea I, zoea II, megalopa) of the spider crab Hyas araneus were studied in the laboratory. Changes in the epidermis and cuticle were documented photographically at daily intervals to characterize the stages of the moult cycle. Stage A (early postmoult) is a very short period during which the larva takes up water. During late postmoult (B) and intermoult (C) the endocuticle is secreted, and there is conspicuous epidermal tissue condensation and growth. The onset of early premoult (D sub(0)) is characterized by epidermal apolysis, occurring first at the bases of the setae in the telson of zoeal instars or in the rostrum of the megalopa.

Description: Larval and early post-larval growth has been investigated in H. araneus L. (Majidae) reared in the laboratory. Growth was measured as dry weight (DW), ash-free dry weight (AFDW), carbon (C), nitrogen (N), hydrogen (H), gross biochemical constituents (protein, lipid, carbohydrate, chitin, ash) and energy (calculated separately from carbon and biochemical composition). During larval development, i.e. from freshly hatched zoea-I to late megalopa, all these criteria of biomass increase by factors ranging between 5 and 14; carbohydrate shows the lowest, chitin the highest increment. There are indications of loss in organic body weight during the latest period preceding metamorphosis to the crab stage. When no food is offered during this time, megalopae lose significantly more biomass than control larvae. This suggests that food is still required, but feeding activity is reduced to a level below maintenance ingestion rate. Following metamorphosis, the juvenile crab accumulates biomass at a far higher absolute rate (expressed as µg/d) than all larval stages.

Description: The development of hard bottom communities has been studied on test panels in Helgoland Harbour (German Bight) since 1977. Settlement and growth of epibenthic species was examined monthly. Natural variation in different seasons, years, and at three stations (the latter, only in 1981 and 1982) was investigated. At Station A (Binnenhafen), barnacles (Balanus crenatus ) and polychaetes (Polydora ciliata ) were always among the first settlers in spring. They were followed by other barnacles (Elminius modestus, Balanus improvisus ) and by colonical ascidians (Botryllus schlosseri ). The latter species often dominated from August to October, and tended to overgrow the barnacle populations.

Description: The larval development f the spider crab Hyas araneus L. was studied in the laboratory at different constant temperatures (2,6,12, and 18 °C). Linear relationships between log temperature and log stage duration were described by means of regression equations. They were used in a simple simulation model predicting larval moulting and metamorphosis at different temperatures. The most important predictions were : (1) Settlement of H. araneus takes place mainly from late May to mid-June; (2) assuming wide annual fluctuations in the average spring temperature ( plus or minus 2 °C), a total settlement period ranging from late April to early July can be expected; (3) delay of larval development due to a decrease in temperature is stronger than the acceleration caused by an equally great increase; and (4) both delay and acceleration effects become weaker during the hatching season and from stage to stage.

Description: Zoea-1 larvae of H. araneus were kept under different nutritional conditions. Their midgut glands were investigated with a transmission electron microscope. The glandular epithelium consists of the cell types known from adult decapods. It is mainly the R-cell type that undergoes ultrastructural alterations which reflect nutritional conditions. R-cells of fed larvae are characterized by large lipid inclusions; after a certain period of food deprivation (point-of-no-return) the original ultrastructure cannot be reestablished. Refeeding results in large glycogen deposits in these cells.
