Description: Summary Holocene sediments of the North Lagoon, Bermuda, were studied with shallow seismic reflection profiles (200 km CSP-survey, UNIBOOM-system) and vibration coring (40 sediment cores, pneumatic vibration corer, Meischner et al., 1981). Seismic Stratigraphy Four seismic sequences are distinguishable by seismic stratigraphy. All seismic sequences correspond to depositional sequences built up during high sea levels in interglacial times. The seismic sequences are separated by unconformities which are often strongly reflective and correspond to emersion planes during glacial phases. The upper sequence (sequence 4) is related to Holocene sediments. The pre-Holocene bedrock is divided into three different seismic sequences (Kuhn et al., 1981): Sequence 1: oldest Pleistocene sequence (pre-Sangamon sea-level highstands), upper boundary with levelled relief (lower boundary not discernible), composed of strongly cemented carbonate sediments, forms the bedrock below Three Hill Shoals Sequence 2: Sangamon (125 ky sea-level highstand), distinct surface morphology, forms the bedrock of a large area below Holocene sediments, Holocene reefs grew up on elevations of the sequence 2 surface, the Holocene reef rim was developed on an elevated rim of sequence 2 Sequence 3: youngest Pleistocene sequence (Sangamon, 105 and 85 ky sealevel highstands lower than recent), deposited mainly in depressions of the bedrock deeper than -15 m below recent Mean Sea Level, levelling the older relief, peat sedimentation in places The distribution of recent reef areas and lagoonal basins is strongly controlled by pre-Holocene topography and geology of the bedrock. During the Holocene approx. 1050 x 106 m3 of carbonate sediments were deposited in the North Lagoon (290 km2) and approx. 1350 x 106 m3 in the reef rim area (170 km2). Sedimentology There are no larger oscillations of the Holocene sea level identifiable in the sedimentological record. The pre-Holocene topography was gradually drowned during the Holocene sea-level rise. At first, the depositional depressions were separated and landlocked. Fresh water peat marshes, fresh water ponds, marine ponds and bays were formed. With rising sea level, the land barriers were more and more eroded, drowned and lost their influence on the back-barrier sedimentation area. Autochthonous and allochthonous peat, lime gyttja and carbonate mud are a typical transgressive back-barrier sediment sequence. After destruction of the barrier, the depositional milieu changed from restricted marine to normal marine, open lagoonal. Sea-grass sediments and nearly mud-free carbonate sand were deposited in shallow water in an exposed environment. Hydrodynamic energy decreases with increasing water depth in the lagoonal basin. A more densely growing reef rim and intralagoonal reef growth added to the protection of the deeper lagoonal floors. Fine-grained sediments were deposited in this environment. They are distributed over a large area of the North Lagoon and form the top of the transgressive lagoonal sediment sequence. Holocene reefs mainly developed on rises of the pre-Holocene surface. In the early Holocene, solid reef build-ups were able to keep up with the rapid rise of sea level. Sand pockets in the reefs were left behind and filled up mainly in the later Holocene. The percentage of fine-grained sediments, produced and resuspended in the reef rim and deposited in the near lagoonal back-reef zone, increased during the Holocene. Two models of Holocene sedimentation in a depression and on an elevation of the pre-Holocene surface illustrate the dependence of vertical facies gradation on pre-Holocene topography. Trends of the mostly polymodal grain-size distributions of the Holocene sediments are a coarsening-upward in the back-barrier and a fining-upward in the lagoonal sediment sequences. Change in the composition of the molluscan fauna in the Holocene sediments (particle size 〉 2000 µm) is an Indication for fades changes. Gastropods are abundant in the basal backbarrier sediments. Bivalves are rare and their diversity 1s low. Sea-grass sediments contain Codakia orbicularis and Astraea phoebia shells. In the sheltered lagoonal environment shell fragments 〉 2000 µm become rare, common species are Gouldia cerina, Pitar fulminata and Finella sp. (approx. 1000 µm). Fine-grained reef-rim derived sediments differ from lagoonal sediments by a higher percentage of Homotrema rubrum fragments and Alcyonaria spicules.

Description: New taxa and combinations are published here in anticipation of the revision of the Rutaceae-Pilocarpinae to be published in the near future (thesis, and in Flora Neotropica). Two new combinations of species excluded from subtribe Pilocarpinae are added.

Description: The author reports the discovery of the moss Rhodobryum roseum (Hedw.) Limpr. in the municipality of Wijlre in the extreme south of the Dutch province of Limburg. This is the first certain find from this area. See distribution map – fig. 2. Rhodobryum occurs on a steep part with a grade of about 30° of a north-facing hillside which borders the valley of the rivulet Geul. This steep part originated by specific land use for several centuries and it forms a part of a pasture which lies below it and is incidentally grazed by cattle. Above the locality a forest stretches towards the hill top. The habitat of Rhodobryum roseum receives no direct sunshine and the microclimatological situation can be defined as open shade. The air humidity is constantly rather high. The subsoil consists of calcareous deposits of Upper-Senone age. The pH measured at a depth of ca. 5 cm. in the soil is about 7-8. The altitude of the locality is about 125 m. above sea level.

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: Op 27 mei 1976 overleed Dr. P.A. Florsohütz op de leeftijd van 53 jaar. Het bericht van zijn overlijden kwam zelfs voor diegenen die gedurende de laatste weken van zijn leven regelmatig kontakt met hem hadden onverwacht. Tijdens de middelbare-sohooltijd kwam zijn interesse in de biologie al duidelijk naar voren. Zowel plant als dier had zijn belangstelling. Na het behalen van het diploma HBS liet Florsohütz zich als student in de biologie aan onze universiteit in schrijven en legde in 1945 bet kandidaatsexamen af. Spoedig daama werd hij kandidaat-assistent bij Prof. Pulle, hoogleraar-directeur van het toenmalige Botanisch Museum en Herbarium. Hét doctoraal-examen werd in 1949 afgelegd.

Description: Floristische und soziologische Beobachtungen über die Flechtenvegetation von Isla Persa, einer Gletscherinsel in der SO-Schweiz (Berainagebiet), in Höhe von 2450-2850 m, werden beschrieben. Die Artenliste nennt 156 Arten. Die interessantesten Funde werden kurz besprochen. Deutlich höher als bekannt aus der Literatur wurden gefunden: Cladonia cyanipes auf 2550 m. Coniocybe furfuracea auf 2650 m. Leprocaulon microscopicum auf 2500 m. Weiter werden einige Flechtengesellschaften auf Isla Persa kurz besprochen: a) epiphytisch: Parmeliopsidetum ambiguae Hilitzer 1925 b) epilithisch: Umbilicarietum cylindricae Frey 1923 Umbilicarietum microphyllae Frey 1923 Sporastatietum testudineae Frey 1922 Sporastatietum polysporae Frey 1922 Ramalinetum capitatae Frey 1923 Umbilicarietum ruebelianae Frey 1925 Dimelaenetum oreinae Frey 1923 Umbilicarietum deustae Frey 1933 c) terrestrisch: Stereocauletum alpini Frey 1937 ? Cladonietum alpestris Frey 1937 Thamnolietum vermicularis Gams 1927 Lecideetum demissae Frey 1923

Description: The African members of the Conocephaloideae are revised. Musanga comprises two species: M. cecropioides and M. leo-errerae. In Myrianthus seven species are recognized: M. arboreus, M. holstii, M. preussii (with ssp. preussii and ssp. seretii), M. libericus, M. serratus (with var. serratus and var. letestui), and M. cuneifolius. M. serratus var. letestui is described as new.

Description: Oil bodies 7-12 in upper leaf cells, 10-20 in elongated basal leaf cells; globose to ellipsoid, 3-7(-10)x3-5 μm; colourless, coarsely segmented, consisting of c. 15-30 aggregated droplets (Colombia, Boyacá, páramos NW of Belén, Cabeceras Q. El Toral, 3765 m, Cleef 2292e; Ecuador, páramos de El Angel, 17 km. S. of Tulcán, 3350 m, Gradstein, Lanier & Weber s.n.). The presence of segmented oil bodies in Colura patagonica is remarkable because previous studies of living Colura (from Japan) reported homogeneous oil bodies (cf. Schuster & Hattori 1964; Inoue 1974).

Description: On 27 May 1976 Peter Arnold Florschütz, bryologist, died at the age of only 53 at De Bilt, Netherlands. Only six weeks prior he had been hospitalized as a result of kidney cancer. His untimely death came as totally unexpected and shocking news to his friends and colleagues all over the world, many of whom had seen him in excellent health the year before at the Botanical Congress in Leningrad. He was a lector of botany and curator of the cryptogamic herbarium at the Institute for Systematic Botany and acting director of the Botanical Gardens of the University of Utrecht, the same institution where he had studied biology from 1941 to 1949. In his professional capacity he had held positions at the Institute for Systematic Botany from 1946 until 1949 as student-assistant and from 1949 on as staff member. Initially under the directorship of his teacher in plant systematics Professor A. A. Pulle, and from 1948 until 1970 under Professor J. Lanjouw’s leadership, the “Flora of Suriname” was being tackled by the staff of the institute. Thus, as a young graduate student, Florschütz was assigned the revision of the mosses of Suriname; a comprehensive and difficult task, because in those post-war years there was a vacuum in European exotic bryology. The heydays, with Herzog in Germany, Brotherus in Scandinavia, Dixon in Great Britain and Thériot and Camus in France were over. At the beginning, Florschütz was entirely dependent on Brotherus’ treatment of the world’s mosses in Engler and Prantl, “Die natürlichen Pflanzenfamilien.” In those years he had run over the leaves of this book for weeks on end in a typical posture, like he used to tell: folded in a chair, book on his lap.

Description: Campylopus introflexus, a new neophyte in western Europe, occurs throughout the Netherlands. After its first appearance in 1961, it is now a common moss. It grows as a pioneer on acid, well-drained places. The differences with C. pilifer are summarized. The occurrence of the latter in the Netherlands could not be affirmed.

Description: The first record of Lophozia perssonii for the Netherlands, from an old and deep limestone-quarry near Cadier en Keer, S. Limburg. Sterile L. perssonii grows here as a pioneer on shaded, calcareous tufa blocks together with Leiocolea badensis and other bryophytes. The differences with related species are discussed, and a description of the ecology is given.

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.

Description: The structure of the wood of the genera Castilla, Helicostylis, Maquira, Naucleopsis, Olmedia, Perebea and Pseudolmedia, considered to belong in the Olmedieae (cf. Berg 1972) is described. The diversity in anatomical structure between the genera is small, and it is hard to distinguish Maquira, Perebea and Pseudolmedia from each other. Castilla can be recognized by its thinwalled and wide-lumined fibres, Helicostylis by its parenchyma distribution, Naucleopsis (usually) by its more numerous vessels with a smaller diameter. A more marked difference is shown by the monotypic genus Olmedia with apotracheal banded parenchyma instead of the paratracheal aliform to confluent-banded parenchyma of the other genera. Septate fibres, which are characteristic for the other genera – some species of Helicostylis excepted – are nearly completely absent in Olmedia. This structural difference is considered as an argument in favour of the exclusion of Olmedia from the tribe Olmedieae (Berg 1977).

Description: The new checklist of Dutch liverworts comprises 126 species, 1 subspecies and 5 varieties. Since 1962 seven liverwort species have been added to the flora: Barbilophozia hatcheri, Calypogeia muellerana, Cephalozia pleniceps, Fossombronia incurva, Haplomitrium hookeri, Lophozia perssonii and Plagiochila porelloides. Of twelve species presumed occurrence in the Netherlands needs verification. Nomenclature follows Grolle’s “Verzeichnis der Lebermoose Europas” (Feddes Repert. 87: 171-279. 1976), except for Isopaches, Leiocolea and Microlejeunea, which are maintained as genera and Phaeoceros carolinianus, Cephalozia lammersiana, Chiloscyphus pallescens, Lophozia silvicola and Lophocolea cuspidata. , which are treated as intraspecific taxa.

Description: The new Amazonian liverwort genus Verdoornianthus is considered to be a specialized derivative of the widespread tropical genus Archilejeunea. Differences are the absence of innovations, the dull, suberect leaves, the tristratose rhizoid pad and the larger size of the lobule of the female bracts in Verdoornianthus. There are two species, V. marsupiifolius (Spruce) comb. nov. (Lejeunea marsupiifolia Spruce) from the upstream part of the Rio Negro and V. griffinii sp. nov. from Manaus.

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: In a recent paper PIERROT (BIZOT, PIERROT & POCS 1974) described the new genus Bizotia based on Paraleucobryum densifolium Thér. (THÉRIOT 1939). However, ROBINSON (1967) already made the presumption that Paraleucobryum densifolium should belong to Campylopus, notably C. argyrocaulon (C.M.) Broth. His conception of C. argyrocaulon was apparently based on MUELLER’s original description (MUELLER 1874) only, which includes a detailed description of the cross section of the costa. We examined part of the type collection of C. argyrocaulon (Wallis s. n., Colombia, NY) but this material, although MUELLER’s description is correct, does not exactly match the type material of Paraleucobryum densifolium (Troll 2144-2145, Colombia, PC-TH). The type material of C. argyrocaulon is identical with one of the paratypes of C. leucognodes (C.M.) Par. (Germain s. n., Bryoth. Levier, Bolivia, NY). ROBINSON also mentions Campylopus pittieri Williams (1908) under the presumed synonymy of C. argyrocaulon. Examination of the type material of the former species (Pittier 1088, Colombia, NY) shows that this species is indeed identical with Paraleucobryum densifolium.

Description: In continuation of de Ruiter’s treatment of Myrianthus and Musanga (Bull. Jard. Bot. Nat. Belg. 46: 471-510.1976), the present paper gives a revision of the African representatives of 17 genera of the Moraceae. The area studied not only consists of the African Continent, but also includes Madagascar, the Comoro Islands, the Mascarenes, the Seychelles, and the Aldabra Islands. Several new combinations are made: Antiaris toxicaria ssp. africana (Engl.) C.C. Berg, A. toxicaría ssp. africana var. usambarensis” (Engl.) C.C. Berg, A. toxicaria ssp. macrophylla (R.Br.) C.C. Berg, A. toxicaría ssp. madagascariensis (H. Perrier) C.C. Berg, A. toxicaria ssp. humbertii (Léandri) C.C. Berg, Broussonetia greveana (Baillon) C.C. Berg, Treculia africana ssp. madagascarica (N.E.Br.) C.C. Berg, and T. africana ssp. madagascarica var. sambiranensis (Léandri) C. C. Berg. Many names are brought into synonymy. Besides revising taxa, the present study aims to fill a gap in our knowledge between Asian Moraceae (studied by Corner, whose studies resulted in a new classification of the family) and the neotropical Moraceae, a subject of study by the present author. Therefore discussions about classification of the family and relationships of African Moraceae with moraceous taxa elsewhere are an essential part of the present paper.

Description: From April 1974 to October 1975 the author conducted field work on the Galápagos Islands for a vegetation study of Santa Cruz and Volcán Alcedo, Isabela. Plants were collected on other islands as well. Thirty-five taxa are new for the archipelago. When determining the material, I found some changes in nomenclature to be necessary. The first set of the collection is in U while a duplicate set will be deposited in CAS. A representative set will be deposited in an Ecuadorian Herbarium. The sequence of the taxa in the Flora of the Galapagos Islands (Wiggins & Porter 1971) is followed.

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.

Description: BAKHUIZEN VAN DEN BRINK Jr, R.C., A synoptical key to the genera of the Rubiaceae of Thailand. Thai Forest Bull. (Bot.) 9 (1976) 15-55. Key of the bracketed type, often leading to flowers as well as fruits, with built-in descriptions of c. 6-12 lines; diagnostic characters are marked. Number of genera 68, incl. 3 introductions and 5 genera not recorded but possibly occurring in Thailand (mostly dependent on delimitation); Craib in 1932-34 has 71. Schumann’s system of 1891 is largely upheld, although no subdivision is here given, and some surprising changes in delimitation occur (e.g. in Keenania, Mycetia, Myrioneuron), which means that many new combinations must be floating around on herbarium sheets. Caution is in order where e.g. on p. 49 Mitragyna seems to have a new section Paradina with a supposedly basal placenta, or where Gardenia is authorized L. on p. 35 but authorized L. emend. Bakh.f. on p. 32. A comparison with Thonner’s keys reveals that Bakhuizen’s key works slower. His generic descriptions are true ’mines of information’ – mining requires a lot of backtracking before all characters can be compared. Desirable as it would be to extend a work like this to all Malesia, it would be better to abandon the Backer-way of keying, and instead describe all genera clearly, and prepare a multiple key as worked out by Leenhouts. Some synonyms are given (Notodontia yes, Quiducia and Symphyllarion no), nomina conservanda indicated, no references, no species. Several critical notes are added. — C.E. Ridsdale & M.J.

Description: The South Asia Institute (see note on page 2342) has changed its address in Heidelberg, Germany: now P.O. Box 10 30 66. Work is in progress on the geography – with a botanical inclination – on Nepal, Ceylon, Java, Sumba, Timor, Papua New Guinea, and Stewart Island, New Zealand. New policy of NUFFIC. The two projects executed by the Rijksherbarium for the Netherlands University Foundation For International Cooperation: seedlings in Bogor and Flora of Thailand, have been completed and discontinued respectively. Both were conceived in the early days of NUFFIC, when initiatives of interested parties were welcomed. Election of a socialist government in Holland in 1973 brought a gradual change in policy, towards larger, multidisciplinary projects for the benefit of the poorest, and we were informed that small projects like the above would not be accepted. We will see what the next elections bring, in 1977.

Description: Portraits of botanists who worked on the Ryukyu Islands, 80 in number, most Japanese, a few Americans, were published in the book by S. Hatusima, Flora of the Ryukyus, p. 56-75 (1971). Baas Becking, L. G. M. A meticulous bibliography, of the former Professor of Experimental Botany at Leiden and later Director of the Bogor Botanic Gardens, was prepared by J. Westenberg, 20 p. (North Holland Publishing Company, Amsterdam, 1977).

Description: Brunonia is the title of a journal that will replace the Contributions from Herbarium Australiense (last no. 17, 1976). Subscriptions Aust. $ 4. annual, Herbarium Australiense, P.O. Box 1600, Canberra City, A.C.T. 2601, Australia. Nature Malaysiana, published quarterly by Tropical Press, 64A Jl. Bukit Bintang, Kuala Lumpur, Malaysia, started in July 1976. The price is Mal. $ 2.50 a copy. This first number, size 28 by 20 cm, containing 40 pages of text and some pages of ads, is devoted to ’our natural heritage’. It is full of showy photographs all in colour, with high quality popular texts on snakes, malaria parasites, spiders, wild orchids, mantis, frogs and elephants. Execution is very good. The journal seems aimed at the general educated public, well suited for display in airline offices, dentist’s waiting rooms, the reading table in an embassy, etc. where is surely will make life more pleasant, and set people’s minds in the proper direction.

Description: Austrobaileya replaces the Contributions from the Queensland Herbarium, and was devised to accommodate also shorter taxonomic notes. The Contributions amount to 20 numbers, with one article each; a cumulative index of names is in no 20, p. 73-88. In format and execution Austrobaileya resembles its predecessor but the useful page heads should be retained. Volume 1 number 1 (1977) was received in March 1978. It carries 9 papers on 74 pages, and a map with subdivisions of Queensland on the back flap. Frequency and price are unknown. Editor: L. Pedley, Queensland Herbarium, Meiers Road, Indooroopilly, Qld. 4068, Australia. Brunonia replaces Contributions from Herbarium Australiense or rather seems a continuation of it in the same scope under a new name, and paged through per volume. The first issue appeared on 24 February 1978, it has 129 pages, carrying 11 papers. It will be ”issued at irregular intervals”. Subscription is A$ 10 per annum. Editor is B.J. Walby, CSIRO, Box 89, East Melbourne, Vic. 3002, Australia.

Description: Localizing specimens and mapping localities has always been a tedious and time-consuming task for which much depends on the data mentioned on the labels. It has been found a blessing if collectors mention on labels the latitude and longitude. If this is given in an exact way it comprises degrees and minutes, e.g. 6° 45’ S, 141° 30’ E. If no dot-map is provided this appears to be a slightly clumsy formula in print and the question arises whether such exact figures are really needed. In scanning a geographical map the minutes will hardly mean something unless one uses local small-scale maps, as one minute is only a little more than 2 km in the terrain. In Pretoria only the degrees are given, joined into one figure, preceding the collector / after the locality. This simplification is, I think, practical and useful.

Description: Tabula Rasa. In 1963 as a missionary I arrived in the Flora Malesiana region, notably in the Lesser Sunda Islands. A certain ’sensus botanicus’ was my only equipment for botanical surveys, and the next thing to do was to walk the arduous but occasionally quite entertaining road to discovery. I often felt like Mr. Columbus when he was discovering America. I entered the New World at Port Said. A lovely ’pine avenue’ drew me, which turned out to consist of arborescent Equisetes! I now realize that it must have been Casuarina, and still these trees, which I grow in my garden are a source of delight to me. Later it was the tropical gardens with their ’unending splendor of flowers’ that captivated my interest, until one day I learnt that Canna indica is of American origin and that there is indeed a kind of commonplace tropical assortment. For meanwhile I had found occasion to set foot in a genuine Asian primary forest, where reality turned out to be a tedious green monotony. This ’dead point’ must perhaps be reached and passed by anyone who finds himself unprepared like me in the Malesian plant kingdom before, step by step, he can learn to know and love the true ’Flora Malesiana’.

Description: ANDERSON, J.A.R., A checklist of the trees of Sarawak, 364 pp. (1983, Dewan Bahasa dan Pustaka Cawangan Sarawak, for Forest Department, Kuching, Sarawak). Cloth Mal$ 15.00. When Dr. Anderson retired from the Forest Department in 1973 he left the manuscript of this checklist for publication. Unfortunately publication was delayed for 10 years. It contains data on over 2500 arboreous plant species. The text consists mainly of two parts: the first is a list of vernacular names with their scientific equivalents, the second is a list of plant names alphabetically arranged by family. Each species is concisely annotated with its vernacular name(s), maximum diameter, ecology, frequency, soils, etc. Species names have been coded: the first two figures are for the family, the next two for the genus and the last two for the species. A list is given of the trees of the peat-swamp forests of which Anderson was a great expert. A small draw-back is that the literature of the last ten years has not been included. Nevertheless this is a most helpful book. — C.G.G.J. van Steenis.

Description: On 3 September 1977, Dr. H.P. Nooteboom (L) went to Ceylon for 2 months to collect additional material of Symplocaceae for ’A revised Flora of Ceylon’. Although this project was due to end by September 1977, it appeared to have been extended for another year. The genus Symplocos, with about 20 taxa, is found in the wet zone (in the mountains of the central part, in the mossy forest up to 2400 m, descending to sea-level in the everwet primary forest in the SW. part of the island). Some species also occur in the secondary forest in the same region, one species is found in the whole island, in a variety of vegetation types, but mostly in secondary forest and shrubbery. Dr. Nooteboom could collect material of all the taxa, sometimes in many individuals, which revealed the difficult patterns of variability. Besides he made also general collections (Nooteboom 3036—3420). The weather was extremely bad; heavy rains caused inundations and landslides. Therefore the total number of collections was limited. Labelling and distribution is still going on.

Description: The preparation of botanical drawings is a craft in its own right, and furthermore, draughtsmen are human beings. Even these simple truths are trodden down by the taxonomist who during a final hour hands the draughtsman a bundle of specimens and some hasty indications. Naturally the result is anguish and confusion. Let us therefore add some observations to improve the situation. First: a botanical artist looks at plants with a different eye from the taxonomist – that’s why he is an artist and not a scientist. Fortunately, some overlap exists, where the two can meet.

Description: Take almost any profile diagram of rain forest and it reveals you the neglect: nothing but trees. Even in Flora Malesiana* the manner of their climbing is not always indicated. Foresters regard them as weeds and persecute them systematically (see FOX 1968), which subjects them to extra dangers beyond the ’normal’ forest devastation. This makes them perhaps the most threatened life form amongst plants. Yet it is good to remember that two of the main climber families, Menispermaceae and Piperaceae, contain an extraordinary variety of interesting chemical substances (see HEGNAUER in the reference list). For this same reason it is risky to drink water from Menispermaceae trunks, as can be done by holding up a fresh-cut piece of 1-1½ m (Piperaceae are slenderer). Rattans, which are largely bound to primary forest, are of course well known, also economically. Horticulturists have taken hundreds of ornamental climbers in cultivation, on which MENNINGER produced a large popular book, with quite a body of practical knowledge. Lianas (i.e. the larger woody vines) occur in a great number of families, although concentrated in about a dozen; taxonomically as well as morphologically they are heterogeneous. They are a main feature of the tropical forests, where according to an old estimate, they make up 8% of the flora, far less so in the temperate forest (about 2% of a much poorer flora). MEIJER (quoted by FOX, 1968) estimated their number for Sabah alone at 150 genera: 13 in the Asclepiadaceae, 12 in the Menispermaceae, 10 in the Rubiaceae, 9 in the Apocynaceae, 9 in the Leguminosae, 8 in the Annonaceae. As for numbers of individuals, in Sabah, FOX (1969) found on ten plots of 0.4 hectares in typical lowland dipterocarp forest an average of 839 climbers (range 472-1146); out of these 690 (range 380-1003) were thinner than 2½ cm, while 56 (range 28-91) were thicker than 5 cm.

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

Description: Dr. J.A.R. Anderson, former conservator of Forests, Kuching, now consultant forester and ecologist, new address: 30 Greenhill Gardens, Edinburgh EH10 4BP, U.K. His Far East address: c/o Room 432, 4th floor, Katong Shopping Centre, Singapore 15. Dr. P.S. Ashton of Aberdeen spent months in Kuala Lumpur, during the second half of 1975, principally to teach economic and forest botany at the University of Malaya.

Description: Small evergreen trees, shrubs or lianas; two genera ( Cansjera and Opilia) are known to be root-parasites. Leaves distichous, simple, usually extremely variable in form and size, entire, exstipulate, pinnately veined; dried leaves mostly finely tubercled by cystoliths located in the mesophyll. Inflorescences axillary or cauliflorous, panicle-like, racemose, umbellate (in Africa) or spicate; bracts narrowly ovate or scale-like, in Opilia peltate, often early caducous. Flowers small, (3—) 4—5) (—6)-merous, mainly bisexual, sometimes unisexual and plants then dioecious ( Gjellerupia, Melientha, and Agonandra) or gynodioecious (Champereia). Perianth with valvate, free or sometimes partly united tepals (in ♀ flowers of Gjellerupia wanting). Stamens as many as and opposite to the tepals (in ♀ flowers only small staminodes); anthers introrse, 2-celled, longitudinally dehiscent. Disk intrastaminal, lobed (lobes alternating with the stamens), annular, or cupular. Ovary superior, 1-celled; style short or none, stigma entire or shallowly lobed. Ovule 1, pendulous from the apex of a central placenta, anatropous, unitegmic and tenuinucellar. Fruit drupaceous, pericarp rather thin, mesocarp ± fleshy-juicy, endocarp woody or crustaceous. Seed large, conform to the drupe, without testa; hilum basal, often in a funnel-shaped cavity. Embryo terete, embedded in rich, oily endosperm, nearly as long as the seed or shorter, with 3—4 linear cotyledons, radicle often very short. Distribution. There are 9 genera with about 30 spp., widespread in the tropics. Rhopalopilia is restricted to Africa and Madagascar, Agonandra to South and Central America. In Malesia: 7 genera, 5 of these only known from the eastern Old World (1 endemic: Gjellerupia in New Guinea); Opilia and Urobotrya occur also in tropical Africa.

Description: Monoecious, medium-sized to very large trees (rarely shrubby in very exposed situations). Either four independent cotyledons or two fused pairs (which may be retained in the seed after germination). The growing point of foliage shoots quite distinct between the two genera, being just a few highly reduced leaves in Araucaria and a highly organized bud formed of overlapping scales in Agathis. The leaves vary from scales or needles to broad leathery forms with many parallel veins sometimes on the same plant at different stages of growth. Pollen produced in cylindrical cones from one to as much as twenty cm long with numerous pedunculate spirally placed microsporophylls each with several to many pendent elongated pollen sacs attached to the lower side of an enlarged shieldlike apex which also projects apically more or less overlapping the adjacent microsporophylls. Pollen cones solitary, terminal or lateral, on branches separate from those bearing seed cones, subtended by a cluster of more or less modified leaves in the form of scales, deciduous when mature. Pollen globular, without ‘wings’. Seeds produced in large, well-formed cones which disintegrate when mature, dispensing the seeds in most cases with the help of wing-like structures; the seed cone terminal on a robust shoot or peduncle with more or less modified leaves that change in a brief transition zone at the base of the cone into cone bracts, formed of numerous spirally-placed bract complexes, usually maturing in the second year. Individual seed cone bract leathery or woody and fused with the fertile scale which bears one large inverted seed on its upper surface. Distribution. The 40 species in two genera are well represented in Malesia (13 spp.) and extend eastward and southward into Fiji, New Caledonia (18 spp.), Australia, and New Zealand, with 2 spp. also in the cooler parts of South America, giving the family a distinct Antarctic relationship. Only one species of Araucaria (in South America) occurs completely outside of the tropics, while the majority of the species in the family belong in the lowland tropics and others grow in the tropical highlands.

Description: The idea to establish a regional organization in order to improve the quality of education in South East Asia was conceived in a meeting of Ministers of Education and Culture in 1965. This idea took shape and was realized in an organization called the SEAMEO (South East Asian Ministers of Education Organization) which was officially inaugurated on February 7, 1968 by the signing of the SEAMEO Charter by seven Ministers of Education, representing the Governments of Indonesia, Laos, Malaysia, Philippines, Singapore, Thailand, and South Vietnam. In 1971 the Republic of Khmer followed as the eighth member country, whereas in 1973 France became an associate member, followed by Australia and New Zealand in 1974.

Description: Many botanists must have wondered why as yet no volume of Flora Malesiana was dedicated to the outstanding botanist Carl Ludwig Blume, undisputed pioneer in planning the compilation of a ‘Flora Malesiana’. The writing of this Dedication would have been greatly facilitated if a full biography of BLUME had been existent, but none is available; there is not even a bibliography of his works. Only recently, in 1979, two biographical attempts were made, by J. MACLEAN and by A. DEN OUDEN, but only for the period 1820-1832; together with other biographical and obituary notes they are here assembled in Appendix B. I have also compiled a bibliography: Appendix A.²

Description: Erect or straggling herbs, shrubs or trees, sometimes monoecious or dioecious, the herbs sometimes rhizomatous; branches sometimes jointed at the nodes, sometimes without vessels ( Sarcandra). Leaves simple, decussate or sometimes whorled in fours, serrate, crenate or dentate, the teeth often thickened at the apex, penninerved, usually petiolate; petioles more or less connected at the base at least by a transverse line or connate into a distinct sheath; in Ascarina often alternating with leafless internodes which have the petiolar sheath; stipules minute to fairly conspicuous, subulate, borne on the petiole bases or sheath, occasionally pectinate. Flowers much reduced, without perianth, fully unisexual or essentially bisexual with the reduced anther-bearing organ adnate to the side of the ovary; arranged in spicate, paniculate, or capitate axillary or terminal inflorescences. — Male flowers bracteate or not, apparently consisting of 1—5 stamens, or in Hedyosmum consisting of numerous anthers in a cone-like structure; if 3 then the whole forming a fused 3-lobed organ sometimes enveloping the female flower by its edges, the central anther with 2 or aborted loculi and the laterals with single loculi, simply lobed or with connectives slightly to considerably produced so that the whole organ is 3-fingered; if with only 2 anther locelli then these on either side of a thickened filament plus connective. — Female flowers naked or enclosed by a cupular bract, the perianth adnate to the ovary, often minutely or shortly dentate at the apex and the ovary thus inferior; ovary 1-locular; stigma sessile or style short; truncate, 2-lipped, depressed or subcapitate (or horseshoe-shaped in one species), rarely linear or clavate. Ovule solitary, orthotropous, pendulous, bitegmic and crassinucellate. Drupes fleshy, small, ovoid or globose, sometimes more or less 3-sided in Hedyosmum, free or united into a mass by the bracts; endocarp hardened and crustaceous. Seeds subglobose, exarillate, with copious fleshy or oily endosperm and minute embryo, the cotyledons divaricate or scarcely formed. Distribution. Four genera with about 80 species. Since VESTER’S (1940) small-scale map the family (Ascarina) has been found in Madagascar. It is mainly tropical but Ascarina extends south to North Island of New Zealand (fig. 6) and Chloranthus and Sarcandra extend north to Japan, China, Korea and the eastern U.S.S.R. (Ussuri).

Description: Trees or shrubs (or rarely suffrutices outside Malesia). Leaves simple, alternate, often coriaceous, glabrous or with an indumentum on undersurface, margin entire; petioles often with 2 lateral glands. Stipules 2, minute and caducous to large and persistent, usually linear-lanceolate. Inflorescence racemose, paniculate or cymose; flowers bracteate and usually bibracteolate; bracts and bracteoles small and caducous or larger and enclosing flower or groups of flowers and persistent. Flowers actinomorphic to zygomorphic, hermaphrodite or rarely polygamous, markedly perigynous. Receptacle campanulate to cylindrical or rarely flattened cupuliforum, often gibbous at base; calyx lobes 5, imbricate, often unequal, erect or reflexed. Petals 5 (absent in some Neotropical species), inserted on margin of disk, commonly unequal, imbricate, deciduous, rarely clawed. Stamens indefinite, 2—60 (to 300 in Neotropics), inserted on margin of the disk, in a complete circle or unilateral, all fertile or some without anthers and often reduced to small tooth-like staminodes; filaments filiform, free or ligulately connate, short and included to long and far exserted; anthers small, 2-locular, longitudinally dehiscent, glabrous or rarely pubescent. Ovary basically of three carpels but usually with only one developed, the other two aborted or vestigial, variously attached to (the base, middle or mouth of) receptacle, usually sessile or with short gynophore, pubescent or villous; ovary unilocular with two ovules or bilocular with one ovule in each locule. Ovules erect, with micropyle at base (epitropous). Style filiform, basally attached; stigma 3-lobed or truncate. Fruit a fleshy or dry drupe of varied size, interior often densely hairy; endocarp much varied, thick or thin, fibrous or bony, often with a special mechanism for seedling escape. Seed erect, exalbuminous, the testa membraneous; cotyledons amygdaloid, plano-convex, fleshy, sometimes ruminate. Germination hypogeal with the first leaves opposite or alternate or epigeal with opposite first leaves. An extensive review of the generic limits of the family has been published: G.T. PRANCE & F. WHITE, The genera of Chrysobalanaceae: a study in practical and theoretical taxonomy and its relevance to evolutionary biology, Phil. Trans. Roy. Soc. London 320 (1988) 1—184. This contains full details of taxonomic history, morphology, anatomy, pollen, ecology and distribution of the family. A condensed version of these subjects is given here. Details of the Neotropical members of the family are given in: G.T. PRANCE, Chrysobalanaceae, Flora Neotropica 9 (1972) 1—410. The African members of the family were treated in: F. WHITE, The taxonomy, ecology and chorology of African Chrysobalanaceae (excluding Acioa), Bull. Jard. Bot. Nat. Belg. 46 (1976) 265—350.

Description: Perennial herbs, more commonly woody at the base, undershrubs or shrubs, erect, scrambling or scandent, sometimes high lianas. Rhizome not rarely tuberous. Branches often slightly swollen and jointed at nodes. Hairs simple, uni- or multicellular, short ones often with a hooked apex. Leaves simple, spiral or alternate, petioled (without an abscission zone), exstipulate; midrib usually prominent beneath, elevated or flat above; nervation commonly palmate, or pinnate, nerves often obliquely extending towards the margin. Flowers bisexual, actinomorphic or zygomorphic, solitary, fasciculate, or in axillary or cauligerous, racemose, paniculate or cymose inflorescences, usually only one or two flowers open at a time; bracts present and often persistent; pedicel often hardly distinct from the ovary. Calyx petaloid, gamosepalous, 3- (or 6-) lobed or 1-lipped; lobes valvate or induplicate. Petals (in Mal.) absent. Disk (?) 0, rarely present (e.g. a few Thottea spp.). Stamens 6 (4 or 5 in some extra-Mal. Aristolochia spp.) or 6—c. 36 (—46), in 1 whorl or in 2 (3 or 4) whorls (Thottea); filaments free or slightly mutually united at the base, and/or almost completely adnate to the style column to form a gynostemium; anthers free (Thottea) or dorsally united with the style column (Aristolochia), each consisting of 2 thecae with 4 pollen sacs, extrorse, rarely introrse (extra-Mal. spp.), dehiscing longitudinally. Ovary inferior (rarely half-inferior in extra-Mal. genera), 4—6-carpellate, 4—6-celled, syncarpous (or ± apocarpous in extra-Mal. Saruma); placentae parietal (distinct when young, then intruding and connivent axially, thus often seemingly axile); ovules usually many, anatropous, in 1 or 2 vertical rows in each locule of the ovary, horizontal or pendulous; style-column 3—many-lobed, sometimes some of the lobes redivided; stigmas or stigmatic tissue apical, lateral, or on the surface of style lobes. Fruits capsular or siliquiform (follicular or cocci in extra- Mal. genera), 4—6-celled; dehiscing apically towards the base (basipetal, e.g. Thottea) or basally towards the apex (acropetal, e.g. most Aristolochia); septicidal, rarely septifragal (some extra-Mai. Aristolochia) or bursting irregularly (extra-Mal. Asarum); rarely indehiscent (W. African Pararistolochia). Seeds many in each locule (1-seeded in extra-Mal. Euglypha), often coated with remains of placental tissue (membranous when dry), horizontal or pendulous, variously shaped; ovate, deltoid or triangular, flat, convex-concave, or longitudinally curved, or oblong (and triangular in cross-section), rugose, finely verrucose, or smooth, immarginate (Thottea; Aristolochia, p.p.) or winged (Aristolochia, p.p.); albumen fleshy, copious; embryo minute, cotyledons two, distinct. Distribution. There are 7 genera, Aristolochia worldwide, Asarum over the northern hemisphere, Thottea in continental Southeast Asia and Malesia, Pararistolochia in tropical Africa, and 3 monotypic genera, viz. Saruma in China, Holostylis and Euglypha in South America. As to number of species, Aristolochia is by far the largest with some 300 spp., largely concentrated in the New World, especially in Central and South America, in Malesia with 28 spp.; Asarum (incl Hexastylis and Heterotropa) with possibly some 70 spp. in northern temperate regions, Thottea with 26 spp., of which 22 in Malesia, and Pararistolochia with 12 spp. in West Africa.

Description: Fungi producing ornamented asexual structures and belonging to the Oomycetes (Trachysphaera) or Zygomycetes (Azygozygum, Mortierella) are described. They were studied by light and scanning electron microscopy while also mating experiments and carbohydrate analyses were performed. Azygozygum chlamydosporum is closely related to Mortierella indohii and therefore Azygozygum is considered to be a synonym of Mortierella. Mortierella echinosphaera spec. nov. is also closely related, but no zygotes are known, only ornamented chlamydospores have been observed. Absence of glucuronic acid and fucose and a low glucosamine content in Trachysphaera fructigena show that it belongs to the Oomycetes.

Description: The genus Mycoacia Donk (1931) originally contained four species, viz. M. fuscoatra (Fr. ex Fr.) Donk (type), M. uda (Fr.) Donk, M. stenodon (Pers.) Donk, and M. setosa (Pers.) Donk. This last species, however, is the type species of Sarcodontia S. Schulzer 1866. Later (1952) Donk considered M. setosa as generically distinct. The monotypic genus Sarcodontia has globose to subglobose spores with thickened walls and is parasitic, while Mycoacia has ellipsoid to allantoid thin-walled spores and is saprophytic. When Mycoacia and Sarcodontia are considered as congeneric (e.g. Nikolajeva, 1961), Sarcodontia is the correct name for the genus. Mycoacia and Sarcodontia are both classified in the Corticiaceae (Donk, 1964; Parmasto, 1968); they are characterized by the resupinate hydnoid ceraceous basidiocarp, the monomitic hyphal system and the smooth non-amyloid spores. The genera are closely related to Phlebia.

Description: Type material of Tulasnella cystidiophora Höhn. & Litsch. has been studied. The species is characterized by often moniliform gloeocystidia and clamp-less hyphae (at least in the subhymenium).

Description: The author describes two new subspecies of Rubus, viz. R. schlechtendalii subsp. subcentreuropus Beek and R. glandulosus subsp. picearum Beek.

Description: The structure of the top of the ascus in live and fixed Sarcoscypha coccinea has been studied with different methods of light microscopy. Electron micrographs have been made of median sections of asci first fixed in 1.5% KMnO4, then postfixed with OSO4. Light and electron microscopy give somewhat different but supplementary information on the lateral wall and the top of the ascus in Sarcoscypha. In the ascoplasm a funnel and a funiculus have been found. The ascus wall consists of three layers. (1) An outer layer, which after different stainings is visible with the light microscope, corresponds with the two outer strata of the stratified electron-transparent layer, and is very thin in the top. (2) A middle layer, which is formed by the inner stratum of the electron-transparent layer, continues with about the same thickness in the top. (3) An inner layer, which is anisotropic and electron-dense, is deposited on the inside of the wall after meiosis. This layer becomes very thick in the top. Its central part is separated by a conical boundary plane to form the basal part of the opercular plug. Former studies on the structure and dehiscence of the ascus are discussed. The view that the ascus is suboperculate and characterized by having an interrupted apical ring is refuted.

Description: The generic names for fungi used by Maratti in his ‘Flora romana’ must be accepted as validly published. Notes are given on the validly re-published names. Of these Agaricum and Coralloides may cause some difficulties. Conservation of Fomes (Fr.) Fr. against Agaricum [Mich.] Maratti is proposed. To the nomina rejicienda of the conserved name Ramaria (Fr.) Bon. Coralloides [Tourn.] Maratti should be added.

Description: During an ecological study of fungi of the tidal mudflats in Kuwait, a Sporothrix species has been recorded twice, in 1977 and 1980. It differs from other species of the genus (de Hoog, 1974, 1978) in several characters and is here described as a new species. A comparison with similar species of the genus is added.

Description: In the course of investigations on the fungal flora of the salt-marsh soils of Kuwait, a Gilmaniella species was isolated twice in 1973. Its smooth vegetative mycelium and large conidia with relatively wide germ pores indicated that it is sufficiently different from the only known species in Gilmaniella, G. humicola Barron (1964), to warrant its description as a new species.

Description: A new species, Alstonia undulifolia Kochummen & Wong, is described from the Malay Peninsula. Two sections of the genus occur in the Malay Peninsula, Alstonia sect. Monuraspermum Mon. and Alstonia sect. Alstonia, the latter being the correct name for what was previously known as sect. Pala (Adr. Juss.) Benth. Various characteristics, including growth architecture, are examined for their usefulness in distinguishing these two sections of the genus. In comparing A. angustiloba Miq. and A. pneumatophora Berger, both of which have not been properly differentiated by characteristics of the reproductive organs, A. pneumatophora var. petiolata Mon. is reduced to synonymy under A. angustiloba. A key to the seven species of Alstonia native to the Malay Peninsula is provided.

Description: Buergersiochloa was described by Pilger in 1914 with B. bambusoides as the only species. A second species was added by S. T. Blake in 1946. Very little is known about this genus; the plants appear to be very rare in lowland primary forests of New Guinea and only 11 collections are presently known, nine of which were directly available for this study, while of a tenth extensive descriptions and drawings have been published. As was already pointed out by Pilger Buergersiochloa is evidently related to Olyra Linné. Phytogeographically this is very interesting, as Olyra belongs to the Olyreae, a tribe of the Bambusoideae practically restricted to the forests of Central- and South America. Only O. latifolia Linné is found also in Africa and Madagascar (probably not in the Mascarenes as indicated by Hubbard, 1959). Some have included the genera Pharus Linné and Leptaspis R. Br. in the Olyreae (e.g. Pilger, 1954), the latter genus occurring in New Guinea also, but Hubbard (1959) and Jacques-Félix (1962) have convincingly demonstrated that these genera belong to a separate tribe, the Phareae. Calderón & Soderstrom (1973) have even excluded it from the Bambusoideae.

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’.

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: In the course of studying the Asteraceae for a proposed Alpine Flora of New Guinea the first author selected the genus Cotula for this separate paper as it showed some variability that was not easily explained. While working on this, Dr. Lloyd’s paper on the genus in the New Zealand Journal of Botany 10 (1972) 277, came to his notice and on corresponding with him it turned out that he had studied the New Guinea species already to some extent but had nothing ready for publication. At the same time, Dr. J. Koster of Leiden, Netherlands, was known to work on a study of all Asteraceae of New Guinea and it soon transpired that when the manuscript was finished and a copy sent to her that very same day she had put down the first words of her manuscript on this genus. She generously allowed us to go ahead with our publication and after Dr. Lloyd had reviewed the first author’s manuscript the paper developed as presented here. This group of small, mat-forming species has been known in New Guinea to date only by C. leptoloba Mattfeld, described from the Wharton Ra. in Papua. Since then, however, it has been collected in several other regions ranging from the Carstensz Mts. in West New Guinea to Mt. Aniata in the southeastern tip of Papua. At first glance the material looked rather homogenous, but on closer look it turned out that at least one species, the material from Mt. Wilhelmina, had to be taken out as new. At this stage, various papers by Dr. Lloyd from Christchurch, New Zealand, drew attention to the group more forcibly and critically. The material available was studied by Dr. Lloyd and he came to the conclusion that at least 4 species should be distinguished, with which the senior author could concur. The differences between the 4 species recognised here are considerable, but the species limits are not well known and the descriptions may need revising when further material is available. Three new species are described below and C. leptoloba is redescribed to include the variation observed in specimens from new localities.

Description: In Malesian Sterculiaceae there was still one enigmatic monotypic genus unsolved, Leptonychiopsis (parviflora) Ridl., J. R. As. Soc. Str. Br. 82 (1920) 173; Fl. Mai. Pen. 1 (1922) 290, described after a specimen collected by a Malayan, 10 Dec. 1892, filed under Ridley 3743. Ridley distinguished this from Leptonychia by its 3-merous flowers. Recently I could borrow a type sheet from the Kew Herbarium to which is attached an ample pencil-drawn analysis. Unfortunately, it is hardly feasible to check this, as there is only one small bud on the specimen, which I did not dare to analyse.

Description: The stomata as occurring on the fronds of the sporophytes of a large number of Polypodiaceae s.s. (Filicales) are investigated. A number of different stomatal types is recognised, (newly) described, and their ontogeny investigated. The different types of stomata are discussed in relation to their possible significance for tracing phylogenetic relationships in the Polypodiaceae following a cladistic analysis.

Description: Revision of the Malesian species of the genus Steganthera, which centres in New Guinea; precursor to treatment in Flora Malesiana. There are 16 species accepted; 5 are described as new, 12 names are reduced, 3 are excluded and 9 are imperfectly known.

Description: In a recent thesis B.S. Fey (Zürich) has developed a new theory about the origin of the cupule in Fagaceae. He has concluded that the appendages (spines, lamellae, etc.) on the outside of the cupule are regularly arranged and that they reflect a condensation (concrescence) of a dichasial flower system, so that cupule and fruit(s) form together the representation of one ancestral inflorescence; the cupular appendages would then largely represent the bracts of the ancestral inflorescence. This stands in contrast with former opinions, in which the cupule was interpreted as of separate vegetative origin from the nut(s) which was (were) the remain (s) of the inflorescence.

Description: Recent studies in Sabah and Sarawak have demonstrated the presence of an undescribed species of Podocarpus.

Description: A world-revision of Arthraxon Beauv. ( Gramineae) is presented. Three wide-spread species, A. hispidus (Thunb.) Makino, A. lanceolatus (Roxb.) Hochst., and A. lancifolius (Trin.) Hochst. are very variable and have caused the description of a great number of taxa, most of which are here reduced to synonomy. There are now 7 species and 9 varieties; for 6 of the latter new combinations are proposed. No new taxa are described.

Description: Tristania R. Brown, Aiton’s Hortus Kewensis (2nd Ed.) 4 (1812) 417, was established with three species — T. neriifolia, T. laurina, and T. conferta. A number of other species have since been added to the genus and a recent study (Wilson, 1971) has shown that the three original species belong to three different groups and further that these groups are sufficiently different to warrant their separation at the generic level. All of the New Caledonian species belong to the Tristania laurina group. It has not yet been decided which of the groups should retain the original generic name, but if the T. laurina group is not selected the name Tristaniopsis Brongniart et Gris, Bull. Soc. Bot. Fr. 10 (1863) 371, would become available for it. Six species are currently recognised in New Caledonia where they mostly grow at low elevations in scrub and forest on ultrabasic rocks. Species of the same group are found in Australia, New Guinea, Borneo, and probably elsewhere in Malesia.

Description: The pollen morphology of all 11 species of the genus Mischocarpus is studied. All species possess basically the same syntricolpate pollen type. Transitions to the tricolpate type were observed rarely. Within the syntricolpate type, subtypes could be established. For a few species a rather wide range of variability in some characters is described. Pollen morphology correlates with macromorphology as well as with geography, thus supporting the results, based on macromorphological evidence, concerning infrageneric structure and relationships of Mischocarpus.

Description: At the age of 85, Herman Johannes Lam died at his house on the 15th of February, 1977. From 1933 to 1962 he was director of the Rijksherbarium and although the day of his retirement lies some 15 years behind us now, he is still remembered in our institute for his pleasant personal qualities. The Rijksherbarium as it is today we owe for a large part to his vision and work during the 29 years of his directorate. He broadened the basis of the institute’s research but kept intact its specialization; he succeeded in obtaining valuable collections; he started a programme of botanical expeditions; he provided a home for the Flora Malesiana, to mention some of his accomplishments. When he came to Leiden after a 14 years’ career in the Herbarium at Buitenzorg (now Bogor, Indonesia) he found a small and rather sleepy institute. Through the years of poverty before and during the war, and through the years of prosperity afterwards, he transformed this into a large herbarium which was (and still is, I hope) very much alive and active in many fields.

Description: In a comprehensive treatment of Caltha, Petra Smit (Blumea 21: 119—150. 1973) unfortunately chose an incorrect name for her fourth variety under C. palustris L. Instead of var. radicans (Forst.) Beck, this taxon should be called C. palustris var. flabellifolia (Pursh) Torrey & Gray (Fl. N. Am. I: 27. 1838). Forster’s C. radicans was described in 1807 (Trans. Linn. Soc. 8: 324) and reduced to varietal status by Beck in 1886 (Verh. Zool. Bot. Gesellsch. Wien 36: 350). According to the current International Code of Botanical Nomenclature, no name has priority outside of its rank (cf. Art. 60). Inasmuch as C. palustris var. flabellifolia was the name first established for Smit’s variety d’, as such it has priority over C. palustris var. radicans (Forst.) Beck by 30 years.

Description: Pholidota kinabaluensis is transferred to the new monotypic genus Entomophobia. Coelogyne phaiostele, C. ridleyana, and Pholidota triloba are identical and transferred to the new genus Geesinkorchis, that also comprises the new species G. alaticallosa. The monotypic genus Sigmatochilus is reduced to Chelonistele, in which C. dentifera and C. lurida var. grandiflora are described as new. Chelonistele crassifolia is regarded as a variety of C. sulphurea.

Description: The genera Hunteria and Lepiniopsis of the family Apocynaceae are in Malesia represented by one species each. Distribution and ecology are cited in full.

Description: Five new species of Rafflesia (Rafflesiaceae) are described, while attention is drawn to a sixth, possibly also new one. A key to all recognized species is given.

Description: The morphology and leaf anatomy of Myxopyrum is described and a key to the species is given. Of the 15 species previously described four species and two subspecies are recognised: M. nervosum Bl. (synonyms M. horsfieldii, M. zippelii) with one subspecies coriaceum (Bl.) Kiew (synonym M. ellipticum), M. ovatum Hill (synonyms M. macrolobum, M. cordatum, M. philippinensis), M. pierrei Gagnep. (synonym M. hainanense) and M. smilacifolium Bl. (synonym M. serrulatum) with one subspecies confertum (Kerr) Kiew. Myxopyrum enerve Steen. is Chionanthus enerve (Steen.) Kiew. Descriptions for the extra-Malesian species, M. smilacifolium, is given.

Description: In subgenus Malachobatus twenty Malesian species are recognized, one of them ( Rubus moluccanus L.) with four varieties. Synonymy, descriptions, habitat notes, etc. are given. New names: R. moluccanus L. var. discolor (Bl.) Kalkm. and var. angulosus Kalkm. A key is given to the Malesian species.

Description: On 11 September 1976 dr. Reinier Cornelis Bakhuizen van den Brink will reach the age of 65 and so he must retire from his position as a senior botanist at the Rijksherbarium. He has worked in our institute since December 1943, after having obtained his doctor’s degree in Utrecht. At the Rijksherbarium he became heavily involved in the preparation of the so-called ‘emergency edition’ of C. A. Backer’s Beknopte Flora van Java, which was mimeographed during the war in order to restrict the chances of destroyal of Backer’s valuable manuscripts. When after the war it was decided to translate Backer’s concise flora into English and to update and complete it, he gradually took over the burden from Backer who in 1945 was already over seventy. As a consequence the Flora of Java, published in three parts between 1963 and 1968, bears both names as authors on the title-page. Quite appropriately too, seeing that he devoted so much of his time, energy, and knowledge to this piece of work.

Description: In Southeast Asia (excluding India) 44 taxa are recognized, 39 species, of which four are newly described ( I. kerrii, I. luzoniensis, I. emmae, and one unnamed species A, which will be treated by Nguyen Van Thuan, Paris), four subspecies, one of which is new (I. sootepensis subsp. acutifolia) and three are new combinations ( (I. suffruticosa subsp. guatemalensis, I. trifoliata subsp. unifoliata, I. trita subsp. scabra) ), and one variety which is a new combination I. spicata var. siamensis). A key, descriptions and full synonymy are given as well as 4 distribution maps and 5 figures.

Description: A sheet of the BSIP collections, gathered in Vanikoro Island, Santa Cruz group, near the proper Solomon Is., had tentatively been identified as probably belonging to Euphorbiaceae, but was discarded by Airy Shaw in 1962 and now again in 1974. Closer examination showed it to belong to Melicytus, a suggestion made by Dr. R. C. Bakhuizen van den Brink Jr. This genus is distributed in the West Pacific Islands, from New Zealand to Samoa; it was mapped by Van Balgooy in Pacific Plant Areas (2, 1966, 103). Though the specimen is male, we assume it to belong to Melicytus, not Hymenanthera. This represents a considerable extension of the generic area. Comparing the floral structure it is distinctly different from the Samoan form and also from M. ramiflorus Forst. by the large, elongated, long-acuminate petals. It is a good match of the Fijian

Description: The factors influencing the development of brashness in timber are discussed. These are reduction in density; changes in moisture content and temperature; ultrastructural changes; changes in chemical composition; and the presence of compression damage. Examples are cited and illustrated. Attention is paid to the recognition of the causes of brashness in the field and in the laboratory.

Description: The duration of cambial activity, and change in wood structure from early to latewood, are considered in relation to the initiation of scale and foliage leaves, and shoot extension, in Picea abies, Pseudotsuga menziesii, Quercus robur, Fraxinus excelsior, and Fagus sylvatica. The initiation of cambial activity appears to be associated with the production of the first scales at the shoot apex, but the cessation of cambial activity does not appear to coincide with the end of primordial initiation at the apex. In P. abies and P. menziesii leaf initiation continues at a rapid rate for several weeks after cambial activity has ceased. In Q. robur, F. excelsior, and F. sylvatica cambial activity continues longer than leaf initiation. The decline in vessel or tracheid diameter is not consistently related to the change from initiation of scales to initiation of foliage leaves. In the ring porous hardwoods the rapid decline in vessel diameter at the end of the earlywood coincides with the cessation of shoot elongation, but in the other species vessel or tracheid diameter declines steadily from the beginning of the earlywood.

Description: A list is provided of the species, subspecies and synonyms of the tipulid genus Nephrotoma Meigen, 1803. The distribution of each species is given in subregional quotations.

Description: The purpose of the Nederlandse Groenland Expeditie 1975 was the study of Long-tailed Skua (de Korte, see page 6) and several species of waders (Bosman, see page 4) in the Scoresbysund region (East Greenland). In addition to skua’s and waders we studied breeding biology of geese in spring and growth and mortality of Arctic Tern chicks on Fame Øer in August. These studies were a continuation of previous work in the area (de Korte, 1973 and 1974). We choose another base than in 1973 and 1974 (Kap Stewart) and worked mainly near Kaerelv at the head of Hurry Inlet. Forty eight bird specimens belonging to 12 species were collected and skinned. The stomach contents have been preserved in spirits for subsequent examination.

Description: A list of the species and subspecies, including synonyms, of the tipulid subfamily Ctenophorinae is provided. References to the literature are nearly complete. The distribution of the species is indicated by abbreviations and figures referring to the geographic regions and subregions. A survey of the distribution of the 5 genera is given separately.

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.

Description: The present material has been collected at three occasions: during a stay on Curaçao and Bonaire (Netherlands Antilles) in 1958/59, and again in 1973/74, and during a visit in 1963 to La Parguera, Puerto Rico. The copepods recorded here as associates of Actiniaria and Corallimorpharia (Asclerocorallia) all belong to the Cyclopoida. Two sections of these are represented: the Poecilostomata and the Siphonostomata. Members of other copepod groups were not found in the Antillean region on the hosts in question.
