    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: 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: 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: 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: 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: 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: 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: 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: 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 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.

    Description: The known mossflora of the small West Indian island Saba (870 m in altitude) consists to date of 48 species, while the neighbouring island St. Eustatius (600 m) has 40 species. The two islands have 27 species in common. Widely distributed neotropical species dominate at all elevations, while wide-tropical (i.e. pantropical) species are found mainly at middle elevations (300-600 m). Species with smaller geographical distributions (southern neotropical, Caribbean) are restricted to higher elevations (above 600 m). An attempt has been made to determine the relation between mosses and the plant communities, encountered along the altitudinal gradient, by calculating “association values”, based on the results of random collecting. Four classes of association values have been distinguished: class A: very characteristic; class B: characteristic; class C: moderately characteristic; and class D: non-characteristic species. It appears that eight plant communities on both islands harbour one or more moderately to very characteristic species. Neckeropsis undulata is the only very characteristic species. It occurs in the evergreen seasonal forest on St. Eustatius. The results are compared with Guadeloupe, Martinique, Puerto Rico, Guyana and Suriname. Finally, a key to the species is included.

    Description: The wood anatomy of the Moreae without urticaceous stamens is described in detail. Generic descriptions of the following genera are provided: Antiaropsis, Artocarpus, Bagassa, Batocarpus, Clarisia, Parartocarpus, Poulsenia, Prainea, Sorocea, Sparattosyce, and Treculia. Wood anatomical variation below the genus level is very limited, except in the genus Clarisia. Intergeneric variation, however, is much more evident. Most genera can be recognised by the presence or absence of septate fibres, and of radial latex tubes, the size of the intervascular pits, the parenchyma distribution, and crystal distribution. The diagnostic and taxonomic value of several characters is discussed.

    Description: Systematic wood anatomy of the tribe Guettardeae (Rubiaceae). The wood anatomy of nearly all genera of the Guettardeae (Rubiaceae, Guettardoideae) has been examined, and in this respect the tribe is heterogeneous. Suggestions are made for a delimitation of the tribe. Guettarda, Bobea, Antirhea, Malanea and Chomelia Jacq. are sufficiently similar in their wood anatomical characters to warrant retention in the same tribe. Machaonia, Timonius and Dichilanthe are anomalous. Suggestions are given for taxonomic revisions of some genera based on their wood anatomy.

    Description: Each dipterocarp has its own species of fungus, forming an ectomycorrhiza. From literature and experiments (in East Kalimantan and in vitro) ecological consequences are explored. These help explain the clumping of dipterocarp trees in the forest, the lack of hybrids, the poor dispersal, and speciation as dependent on the viability of the root-fungus combination on a particular soil type. Mycorrhizas are located in the top soil. They are extremely sensitive to increase of soil temperatures as occur after canopy opening, and to soil compaction by machinery and log skidding. This explains the setback of dipterocarp growth after crude logging. It is suggested that avoidance of soil compaction during logging, quick restoration of soil cover, and the use of fungus-inoculated seedlings for enrichment planting are important consequences for forest management. Key words: Dipterocarpaceae, ecology, enrichment planting, logging, management, mycorrhiza. Mycorrhiza — Dipterocarpaceae — The role of the symbiosis — The influence of logging on the fungi — Conclusions — References.

    Description: Outside Australia, five species of Dodonaea are accepted, viz. D. viscosa, a pantropical coastal species, D. angustifolia, an inland species occurring throughout the Tropics and Subtropics, D. elaeagnoides, restricted to Florida and part of the Antilles, D. polyandra, restricted to a small part of Papua New Guinea and of Queensland, and D. madagascariensis, endemic to Madagascar but with clear connections to Australia. Out of these five species three, viz. D. angustifolia, D. elaeagnoides, and D. viscosa were for a long time combined under the last mentioned name. In Chapter II arguments are given for the division of that complex into three species and it is tried to give a historical explanation for the final state of confusion. In Chapter III notes are given on the five accepted species. All further species names used by or after Radlkofer outside Australia are rejected; a discussion of these names is given in Chapter IV.

    Description: In 1979 a combined Indonesian-Dutch expedition, sponsored by WOTRO, was held in Sulawesi, Indonesia. In addition to herbarium material, a large number of living orchids was collected. The living plants were distributed to the Kebun Raya, Bogor, the Hortus Botanicus, Leiden, and the Hortus Botanicus, G.U., Amsterdam. Among the specimens which flowered in Leiden, two different species appeared to belong to the genus Bracisepalum. This genus was hitherto only known from the type collection of B. selebicum. Additional herbarium material of this species was collected by Van Balgooy in the field. This article is the first in a series of treatments for Flora Malesiana of genera belonging to the subtribe Coelogyninae, by the first author. The next revision will cover Pholidota and related genera. Mr. J. Vermeulen is responsible for the scientifically very accurate and beautiful drawings.

    Description: On most of the islands on which it has become established, the small Indian mongoose has commanded more attention than all indigenous mammals and introduced exotics. As a consequence of its impact on the neotropical single island ecosystems, both as a predator and as a vector of human and animal diseases, the mongoose is uniquely significant. The present study of the mongoose was initiated in 1968 when Everard was appointed by the United Kingdom Medical Research Council (MRC) to the Caribbean Epidemiology Centre (CAREC), formerly the Trinidad Regional Virus Laboratory (TRVL). The terms of the appointment included a study of the biology of the mongoose in Trinidad and Grenada, surveillance of mongoose rabies in Grenada, and an investigation of methods to control mongoose rabies. Coincidentally, in 1968 Nellis was contracted by the Government of the U.S. Virgin Islands to investigate the wild hosts of the African Bont Tick Amblyomma variegatum (the mongoose being of primary concern). The study was continued in a survey of wild animal parasites and diseases of concern to man or livestock, and it gained impetus as part of the rabies contingency plan for the Virgin Islands. Throughout the course of their work, the investigators continuously exchanged ideas, opinions, data and techniques.
