Description: The three species Galium silvaticum L., Galium aristatum L. and Galium schultesii Vest show differences in morphology, cytology and geographical distribution. These differences are described and discussed. Crossing experiments between the three species were without results. No hybrid could be obtained. Galium silvaticum, Galium aristatum and Galium schultesii must be considered as separate species.

Description: Although a large number of Tortricoid species and several genera from the Indo-Malayan region have been described by earlier authors (Walker, Snellen, Walsingham, Meyrick, and a few others), no survey of the present group has ever been made. Edward Meyrick, the author of most of the new names, has never attempted a synopsis of the Olethreutinae. He made surveys of the Australian and New Zealand Tortricoidea (1911), but the results are too superficial for our modern standards. During a long sojourn, working and collecting in Java, I became greatly fascinated by that fauna. Having completed a number of preliminary studies of the subfamily Tortricinae (1939 et seq.), I turned next to the South Asiatic, especially Javanese, Olethreutinae. After a long delay due to World War II, their revision has been initiated by the study of the two then least known and most confused genera, Bactra Stephens and Lobesia Guenée (Diakonoff, 1950 et seq.).

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

Description: Three sections with a total number of four species of the genus Phyllanthus have been examined. The pollen grains show a strong resemblance to each other and also the taxonomic arguments to differentiate between the three sections proved to be rather weak. Because of both palynological and taxonomic reasons the sections Ceramanthus Baillon, Cluytiopsis Mueller Arg. and Anisolobium Mueller Arg. have been united into one section; viz. section Ceramanthus Baillon s.l.

Description: As an introduction to a number of researches of his own the author wishes to give the following data: „Veen” has two meanings in Dutch: 1. in a petrographic sense (peat) Von Büllow’s definition was accepted: „Torf” ist zu deflnieren als ein meist dunkles, kohlenstoffreiches und ± saures Gemenge unvollständig spezifisch-zersetzter Pflanzenteile, das erdgeschichtlich jüngste Glied der Verwantschaftsreihe der Kohlen, dessen Bildung noch heute andauert.” 2. in a plant-sociological-geographic sense (bog) the following definition has been suggested: a bog is a plot, the surface of which consists of a layer of peat, either covered or not with vegetation, with which that layer is genetically connected. The classification of bogs according to their position with regard to the water-level of the surroundings (Staring) and that of the geological chart were rejected on account of their ambiguous character. The classification suggested by Van Baren according to the environment in which the bogs have been formed, was likewise thought insufficient. Preference was given to the classification according to the plants which gave rise to the peat (eutrophic, mesotrophic and oligotrophic bogs) and according to the origin of the water needed for peat formation (topogenous, ombrogenous and soligenous bogs). The conditions of peat-formation are of a botanical (presence of a vegetation and micro-organisms), climatologic (presence of a certain temperature and moisture) and geological nature (presence of a basin, valley or dead river-branch, certain level of ground water, a possible impervious layer). With reference to a number of authors (Picardt; Van Lier; Grisebach, Venema and Staring; Weber) the alteration in conception as to peatformation from the 17th via the 18th and 19th to the 20th century has been given. The word „Peel” cannot be derived from „palus”. Nothing is certain about its origin. It may mean the low land, bog or marsh. The bogs of the Peel lie on the Brabant-Limburg border-plateau (fig. 2). Lorié and Pannekoek van Rheden have shown that the peatformation of the Peel is likely to have occurred in channels, which have been formed by the Meuse, in co-operation with wind and rain (fig. 4). The bogs were therefore in the first instance topogenous formations, which afterwards developed into ombrogenous bogs. For his own research the author collected peat in three ways: 1. by cutting lumps of peat from open profiles; 2. by boring with a simple peat-bore (photograph 1); 3. by boring with the Utrecht peat-bore, an improvement on Dachnowski’s (fig. 5). To assist in the pollen-analytic examination the samples were treated according to Erdtman’s method. The latter has the following advantages compared with the usual treatment with a 10% KOH-solution: 1. the surface-structures of the pollen-grains are more distinct and as a result the grains themselves can be recognized better; 2. the pollen is more concentrated, so that in spite of the method taking up much time, a saving of time is possible. How the method is applied may be found in the chapter concerned (p. 38 and following). For the stratigraphic examination the samples were broken apart in a glass-bowl of water and viewed with a binocular microscope. Dry sandy samples were broken in water, when seeds and other vegetative parts came floating to the top; next they were put with a brush on thick blotting paper and studied through the binocular microscope. The designations for the sediments and species of peat have been derived from Fægri & Gams. For Scheuchzeria peat a new designation has been added. A plea was made for replacing the word pollen-analysis by „palynology”. A survey of the observations and examinations up to abt. 1935 closes the introduction (see the diagrams of Weber, Erdtman and Duyfjes in the figs. 6, 7, 8 and 9). The author’s own research refers to the Southern and Astense Peel, as in the remaining grounds of the geological chart indicated I 4v (= raised bog) no samples could be taken owing to the digging off having progressed too far. 10 profiles were examined. The situation of the bore-sites has been given in the geological chart of the grounds (fig. 3). The result of the examination (figs. 10—27) and the discussion on it may be summerized as follows: Zoning of pollen-diagrams The sub-zoning of the late- and post-glacial periods according to Blytt & Sernander has proved useful as a zoning of pollen-diagrams, provided atlantic and sub-boreal are joined. It is desirable to replace Blytt & Sernander’s terminology by a different one, because the authors gave a climatologic connotation to their names of periods. The limit between pleistocene and holocene was drawn between preboreal and boreal as Florschütz did. As phases of the holocene the following names were suggested: young post-glacial = sub-atlantic mid post-glacial = sub-boreal and atlantic old post-glacial = boreal. Neither in the Peel nor elsewhere in Holland have Allerød-deposits been found. They are not likely to be found either, as on account of the long distance from the land-ice-margin the flora will have been hardly or not at all influenced by the Allerød interstadial period. For Holland therefore the zoning of the late-glacial according to Firbas (1935) may be considered sufficient. The names of the periods do not bear a climatologic connotation as those of the post-glacial phases do. For the sake of a unity the following names have been suggested: young late-glacial = pre-boreal mid late-glacial = sub-arctic period old late-glacial = arctic period. Forest-history In a table (p. 98), in which likewise the Peel diagrams of Weber, Erdtman and Duyfjes have been inserted, the examined profiles have been arranged from North to South. From each profile it has been stated whether it originated in a certain period (+) or not (—). The sub-arctic phase was characterized by forests of Betula and Pinus and was followed by the pre-boreal phase, in which Corylus and Alnus occurred. Also from the other Dutch diagrams (see list on p. 99) it appeared that in the Netherlands the Alnus pollen occurs with an equal frequency before, during and after that of the Quercetum mixtum. The old post-glacial zone of the diagrams shows a peak in the Pinusline. In contrast with the from Mid-Europe there is not always a maximum in the Corylus-curve after the Pinus-peak. In other Dutch diagrams this phenomenon is likewise found. Only in 28% of all Dutch profiles with a boreal zone does a hazel-maximum succeed a Pinus one. They often co-incide (16%), while in the remaining cases no hazelpeak has been established. There is no fixed order of sequence in the occurrence of the components of the Quercetum mixtum, either in the Peel or elsewhere in Holland. The mid post-glacial is the phase of culmination of warmth-loving forest elements: Alnus pollen shows the highest percentage in this zone. Quercus pollen also occurs in great quantities, while Ulmus and Tilia take up an important place up to the „Grenzhorizont”. The absolute and empiric Fagus pollen limits are found at different heights in the mid post-glacial zone of the diagrams, the rational limit lies somewhere near the „Grenzhorizont”. In the young post-glacial phase the Fagus pollen attains fairly high percentages (up to 30%). The maxima in the East and South-east of the Netherlands are between 20% and 38%; they decrease towards the coast and increase towards the South-east (Hautes Fagnes, Belgium) and East (Germany). It seems incorrect to class the Netherlands almost entirely among the oak-alderterritory poor in beeches, as Firbas did. An attempt has been made to fit the Peel-diagrams into Overbeck & Schneider’s zonation system. For the territory for which it has been made there are already difficulties (p. 104), for use in the Peel and other Dutch diagrams there are even more objections (p. 68, 104). Godwin’s zonation system appeared to be a little less forced, but not quite useful on account of too many details. From his horizons that of Ulmus proved useless for the continent. Neither for the Peel nor for the Netherlands and its surrounding territory can a detailed zonation system be designed. It has proved difficult to proceed any farther than Rudolph’s „Grundsukzession”: birch, pine-hazel-mixed oak-forest-beech, in which the alder generally joins the mixed oak-forest and the hornbeam the beech. Before drawing far-reaching conclusions from the course of the curves (as has been done by some authors) more palynological researches are needed in accordance with the actuality principle, known from geology. Pollen-grains from warmth-loving trees in seemingly sub-arctic spectra In profile 4 (Deurnse Peel II) pollen-grains of Abies, Alnus, Picea, Tilia, Ulmus and Corylus were found in the „late-glacial” zone (figs. 14, 15). Investigations were made as to which of the following possibilities would be the cause of their appearance: 1. in taking and preparing the samples pollution occurred; 2. pollen-transport over long distances has taken place; 3. the pollen-grains found have got secondarily into the deposit; 4. warmth-loving trees have occurred in favourable circumstances in the late-glacial phase or 5. in an interstadial period or in an interglacial phase. The said pollen-grains probably hail from a Würm interstadial or interglacial phase. Interglacial peat On the site of the bore-point 7 it was possible to collect samples from the layers under the peat. The upper 40 cm of the diagram Griendtsveen IX (fig. 27) of this profile proved a repetition of the lower 40 cm of the Griendtsveen I profile (fig. 18). The diagram shows that pollen of Carpinus, Picea and Abies occurs showing the deposit to be of interglacial age. The pollen-curves, however, pass unnoticed from an interglacial into a post-glacial portion. The limit is likely to be found between the two, about 30 cm below the mowing field. There is therefore a great stratigraphic hiatus. Pollen-analytically it could not be decided from which interglacial period the profile hails; on account of its situation on the middle terrace, it was deemed likely that it was an Eem sea deposit. The examined profile probably corresponds to Jessen & Milthers’ zone g; showing it to have been formed at the end of the Eem sea period. The Meuse therefore cannot have flowed through this part of the Astense Peel after the mid Eemean phase. Stratigraphy This is difficult to summarize. Compare various profiles. Individual mention may be made here of: 1. peat on a podsol layer; this was found in two places (Deurnse Peel I Kraaienhut and Griendtsveen VIII). Peat-formation may be thought to have occurred in the following way: heather started growing on drift-sand giving rise to a podsol layer. As the latter is impervious the vegetation surface became marshy. The heath was replaced by a Caricetum from which peat arose. Gradually more Eriophorum occurred, from which almost pure vaginatum peat arose. The bog-surface grew moister and moister, Sphagnum cuspidatum and Scheuchzeria could grow on it and formed a „Vorlaufstorf”. Only then could non-extremehydrophile Sphagna join in peat-formation. 2. the occurrence of Scheuchzeria-peat after the „Grenzhorizont” period. This species of peat, which is often found at the basis of the old Sphagnum-peat as a mesotrophic transition vegetation, has for the Netherlands only been found in the young post-glacial phase in the Peel (Deurnse Peel I Kraaienhut, Griendtsveen V and VIII and Nederweerd). At present the plant is very rare. The severe decline of this plant was also observed elsewhere. Probably it is caused by the gradual drying up or reclaiming of the raised bogs. Of the present station of Scheuchzeria near Ommen a short description has been given (p. 59 and photographs 2, 3, 4). 3. the „Grenzhorizont”. Where the young Sphagnum-peat has not been dug for the preparation of moss-litter, the Peel bogs show a clear „Grenzhorizont” (photograph 8). The conceptions about its origin have been discussed. The distinct separation between the old and the young Sphagnum-peat was not considered sufficiently explained. Though on the whole the „Grenzhorizont” is synchronous in the North-west European profiles, the point of transition from old to young Sphagnumpeat was fairly unstable and easily changeable as to time. Generally the date of the „Grenzhorizont” is fixed at about 500 A.D., though there are differences in opinion. There is a lack of archeological correlation which renders a correct dating impossible. Interference of man in the Peel Three ways of interference were stated: 1. peat has been dug off for the greater part in the territory of the Peel: young Sphagnum-peat for the preparation of moss-litter, old Sphagnum-peat for fuel. The trees which appeared when the bog was dug up in the „Veenderij der Maatschappij Griendtsveen” are sometimes in so good a condition, that they are used for building sheds. The 1 st, 2nd and 4th beam in the foreground of the shed in photo 5 has been sawn from a 30 m long subfossil pine. 2. in a native peat-digging it was possible to collect recent young Sphagnum-peat. 40 to 50 years ago the peasants living there had dug peat in holes, which were afterwards left to themselves. Sphagnum started growing again and the holes were filled in again. The diagram (fig. Griendtsveen VII) represents the surrounding heath with scattered pines and birches, sown by the wind, and a pine-plantation close by. 3. in the profiles Nieuwe Peel, Griendtsveen VI and VII it has been fixed by the indications given by Firbas, that only in the surface layers of the bog has corn-pollen occurred. So in these parts cultivation of cereals will be of recent date. This also appeared from the history of the reclamation of the said territory.

Description: Dicranella riparia (H. Lindb.) Mårt. & Nyh. is reported for the first time from Greenland, where it was found on a fluvioglacial delta in the Angmagssalik District in plant communities belonging to the association Calamagrosto-Ditrichetum (all. Calamagrostion neglectae). This is the sixth locality known, and the first outside Fennoscandia.

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

Description: This study deals with the taxa of the section Rubus of the genus Rubus L., so far as they are found in the Guelders district within the flora of the Netherlands. It concerns fifty species and some subspecies and varieties, mainly of the subsections Fruticosi Wimm. et Grab. and Discolores P. J. Müller. The similarity with the bramble-flora of northern Germany is obvious. A number of species, that occur in the latter region are absent however. Species of Central-European hills and mountains are as good as limited to the southern border of the Veluwe, which is mostly considered to belong to the Subcentreuropean district. South-European, often calciphilous species are absent. The nomenclature in the genus Rubus is very confused. There is an abundance of homonyms and synonyms. The number of misidentifications is rather large, meaning that a great deal of the literature is unreliable. The descriptions with many authors are absolutely insufficient, and type-specimens are often with difficulty or not at all to be traced. The difficulties arise from the fact that many taxa are not clearly separated. Some of them are well distinguishable, others are related by transitions. From a geographical point of view there is much difference as well. Some species have as their area almost the whole of Europe, others are limited to a very restricted area. In addition there is a difference in chromosome numbers (from diploids (2n = 14) to hexaploids (2n = 42). Most taxa are tetraploid. The abundance of forms within the section Rubus arises from a partly apomictic, partly amphimictic propagation. To set up some order in all those differences, the author has made the following distinctions: morphologically there are the different ranks of species and infraspecific taxa. Geographically distinctions have been made by means of a code of the capitals A to D inclusive: A indicates the taxa with the largest area, D the local taxa. Cytologically a code of Roman numerals has been given: I for diploids, II for polyploids. Beside the introductory theoretical part a short description of all taxa of the section above the specific rank has been given. All species and infraspecific taxa of this section, that are found to occur in the Guelders district have been described in detail, with mention of the type-specimen. Pictures have been added of the newly described taxa, and of some others as well. Maps of the distribution in the Netherlands of all the taxa have been inserted.

Description: This paper is an addendum to the author’s (1971) paper. At the time that the latter paper was finished, there were difficulties in taking photographs of the newly described male fructifications. Subsequently those difficulties have been solved, and the present paper contains the photographs of the male fructifications of the type specimens of Hastystrobus muirii v. Kon., Masculostrobus harrisii v. Kon., and Pityanthus scalbiensis v. Kon., and the photographs of the male fructifications, as described in the above-mentioned paper, of Ginkgo huttoni (Heer) Sternberg and Brachyphyllum crucis Kendall. All specimens are preserved in the Division of Palaeobotany and Palynology, Botanical Museum and Herbarium, State University, Utrecht, The Netherlands. Most of the photographs were taken with the specimens illuminated obliquely in air, but some were taken with the specimens flooded with oil. This procedure is generally applied when the specimen requires enhancement of contrast, so that details are more evident than if the specimen was photographed dry.

Description: Since the completion of Radlkofer’s monumental work on the Sapindaceae in Engler’s series “Das Pflanzenreich” 50 years have now elapsed, almost 40 since its publication. It is still the basis of virtually all taxonomic studies in the family. Some of the gerontogean genera have since been the subject of revisional work (Leenhouts 1969, 1971), but for the neogean representatives there are only some regional treatments (e.g. Rambo 1952; Barkley 1957; Reitz 1962; Soukup 1969), apart from descriptions of new taxa scattered through the literature. When studying the taxa native to Suriname in connection with the preparation of a supplement to the family treatment published previously in the “Flora of Suriname” (Uittien 1937) it soon became apparent to me that the genus Talisia was particularly incompletely known when Uittien published his account of the family, actually not much more than an extract from Radlkofer’s work. The number of species known or to be expected from Suriname proved to have doubled; this is not due to inadequateness of Uittien’s work but to much more extensive collecting. Two of the species met with since could not be identified with any species dealt with by Radlkofer or described after his time: these are described as new below. In order to establish that they were truly undescribed the descriptions and, where possible, types and/or other authentic specimens of all species described after Radlkofer were checked. A list of these follows; it may serve as a kind of bibliographic supplement to Radlkofer’s monograph. The two species marked with an asterisk have been posthumously listed in the supplement to his work.

Description: Dicranella staphylina Whitehouse, a species recently described from Great Britain, is now recorded from Belgium, Denmark and The Netherlands. A new combination, Anisothecium staphylinum (Whitehouse) Sipman, Rubers & Riemann, is proposed. A study of the costal anatomy revealed that A. staphylinum in this respect most resembles A. rufescens.

Description: The author studied the morphology of Blackstonia perfoliata s.l. and compared its variability with that of the other representatives of the genus. She also carried out ecological studies of “Blackstonia perfoliata ssp. serotina” on the Dutch island Voorne and compared her results with those in the literature relating to B. perfoliata in some adjacent regions, notably the Upper Rhine area. On morphological and ecological grounds B. perfoliata ssp. perfoliata and ssp. serotina are to be regarded as two distinct species, B. perfoliata and B. acuminata.

Description: In a forthcoming publication (Kramer, in prep.) floristic and taxonomic data of the pteridophyte flora of Suriname will be assembled, with keys and notes on their local distribution and ecological preference. The present paper deals with the geographical distribution of Suriname pteridophytes beyond the boundaries of Suriname (Fig. 2), a subject that lies beyond the scope of a local fern Flora. In the past, some (but relatively not very many) authors of fern Floras included a paragraph on the distribution of the taxa (Posthumus, 1928; Christensen, 1932; Backer & Posthumus, 1939). In some other fern Floras some space is devoted to ecology, but very little to geography (Holttum, 1954). In still others, considerations of a general kind on ecology and geography are altogether lacking (Vareschi, 1969). Lyell (1870), in his rather little-known book on the distribution of ferns, tried to bring together all the data known at his time; his work is now, of course, almost exclusively of historical significance.

Description: The pollen analyse of a raised-bog on the High Vosges crest shows the vegetation regional development since 3200 years. A prehistoric civilization, the Gallo-roman period, the great migrations and the Carolingian period are reflected in the pollen diagram by N.A.P. minima and maxima. A discussion on curves fluctuations of the main A.P. follows.

Description: Cytological investigations within Galium palustre L. showed the occurrence of three cytotypes, a diploid with 2n=24 chromosomes, a tetraploid with 2n=48 and an octoploid with 2n=96. Comparative morphological investigations, together with transplantation and crossing experiments confirmed the complexity of the species. The cytotypes are here considered to be subspecies of Galium palustre L.

Description: The wood descriptions of Juniperus communis L. ssp. communis are compared with those of earlier authors. The average and maximum tracheid lengths and the ray height distribution frequencies offer a means of separating the wood of the erect J. communis L. ssp. communis from that of the subspecies nana Syme with an entirely different habit.

Description: Caudalejeunea grolleana Gradst. spec. nov. from Madagascar is referred to this genus with some doubt because of the absence of gemmiparous branches. Ptychocoleus cristilobus (Steph.) Steph. from S. E. Asia has gemmiparous branches and therefore is a true Caudalejeunea: C. cristiloba (Steph.) comb. nov. This species is remarkable by its complicated ciliate leaflobule and by its polystratose rhizoid-disc. Two subspecies are distinguished: ssp. cristiloba from Burma, Andaman Is., Thailand, and Singapore, and ssp. samoana (Steph.) comb. nov. (Caudalejeunea samoana Steph.) from Samoa. Both C. grolleana and C. cristiloba have a 4-5-carinate perianth, which shows that the trigonous perianth present in most species of Caudalejeunea is not a stable character of this genus.

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

Description: Cytologioal investigations within Galium boreale L. showed the occurrence of tetraploids (2n=44) as well as hexaploids (2n=66) in Europe. Comparative morphological studies failed to demonstrate any differences in characters between the two cytotypes. Crosses between the tetraploid and hexaploid were unsuccessful, due to the occurrence of a strong and effective barrier between the two levels of ploidy. From a taxonomical point of view the two cytotypes are considered as to belong to the same taxon.

Description: The chromosome numbers of 67 species of Dutch Angiosperms were determined. Notes on 11 species are added.

Description: With the appearance in 1889 of Engler’s treatment of the Urticales in “Die natürlichen Pflanzenfamilien” there came a pause in the interesting development of the classification of this group, which was defined, albeit somewhat vaguely, by A.L. de Jussieu in 1789 in his “Genera Plantarum” as the order Urticeae. Since the 1830’s, many, including Gaudichaud, Trécul, Miquel, Bureau, Eichler, Baillon, and Bentham, have contributed to the establishment of the Engler system which until recently has been generally accepted. An important moment in this history was the appearance of Trécul’s treatment of the then most problematical group, the “family” Artocarpeae. Trécul (1847) considered the “families” which at that time were distinguished within the “class” Urticineae, viz Moreae, Urticeae, Ulmeae, Celtideae, and Cannabineae, as being very closely related to the Artocarpeae. Along with the Conocephaleae, split off from the Artocarpeae, we find these “families” as tribes of the “class” Urticaceae in the “Genera Plantarum” of Bentham and Hooker (1880) and as subfamilies or families in Engler: the subfamilies Moroideae, Artocarpoideae, Conocephaloideae, and Cannaboideae in the family Moraceae, the subfamilies Ulmoideae and Celtoideae in the family Ulmaceae, and finally the family Urticaceae. Since the end of the last century and until recently no revisions of any large groups of Moraceae and Urticaceae had appeared. But with the development of monographic taxonomic research the system has come out of its static situation, as can be seen from the study by Corner (1962). He proposed a new delimitation of the Moraceae and Urticaceae and another subdivision of the Moraceae sensu stricto.

Description: Controversy over the taxonomic relationship of the Taxineae with the Coniferineae has created a new interest in the field of wood anatomy. This has been reflected by the flurry of investigations being conducted in families such as the Podocarpaceae. The systematic position of Amentotaxus is somewhat uncertain (see Keng, 1969). While many authors place Amentotaxus in the Taxaceae, this genus has also been referred to the Cephalotaxaceae or even considered to represent a separate family, the Amentotaxaceae. When Kudo and Yamamoto (1931) described this last family, it was considered to be represented by only a single species, Amentotaxus argotaenia (Hance) Pilger. In his revision of Amentotaxus Li (1952) recognized four species. However, the description and publication of three new species of Amentotaxus based on leaf morphology would appear to have been overly optimistic and has not gone unchallenged. Hu (1964) recognized only three of the species, since she thought that Amentotaxus cathayensis Li could not be usefully upheld as distinct. Moreover, Chuang and Hu (1963) considered that Amentotaxus formosana Li was better referred to Amentotaxus argotaenia (Hance) Pilger. The divergence of opinion has increased the need to investigate any anatomical features that may be of taxonomic importance. In connection with this work it was thought an examination of the wood anatomy would be worthwhile, even though taxonomic evaluation at the subgeneric level is not often successful in this field. A comparative study of the wood anatomy within the genus Amentotaxus is considerably limited by the lack of availability of suitable material; most locations of Amentotaxus are in China. The scanty and now somewhat rare wood specimens were collected before 1935, with the exception of some from Taiwan.

Description: This paper is a preliminary account of investigations on species of Campylopus, mainly from the high Andes of Colombia and from adjacent regions. The studies are based on herbarium specimens, field studies and cultural experiments. The genus Campylopus was founded by Bridel (1819) on the basis of a curved seta only and included, therefore, species of Grimmia and other genera. Later he modified his earlier circumscription (Bridel 1826) so that the genus then contained (except for one uncertain species) only species of Campylopus as known today. A subdivision of the genus was made by Limpricht (1886) based on the structure of the costa as seen in cross section: Pseudocampylopus Costa without stereids, ventral layer of large cells, other cells containing chlorophyll with moderately thickened walls. Campylopus Costa with dorsal stereid groups. Palinocraspis Costa with dorsal and ventral groups of stereids.

Description: Nooit zal ik die Donderdagmorgen 10 Augustus 1944 vergeten, toen ik op het laboratorium hoorde dat in de krant — wie las dat vod nog in die tijd — stond dat UITTIEN gefusilleerd was. Het drong eerst niet goed tot mij door. Het kon niet waar zijn. De krant werd gehaald. Ja, daar stond zijn naam in een lange lijst van lotgenoten en het verschrikkelijke, het onherroepelijke, begon langzaam tot mij door te dringen. Koud en gevoelloos stond daar het bericht, van een leugenachtige argumentatie voorzien, dat men ook UITTIEN, die zachtmoedige, gevoelige, intelligente man, had vermoord. Woorden waren hiervoor op dat moment niet te vinden. Ik had alleen behoefte zijn oudste zuster, waaraan hij zeer gehecht was, op te zoeken. Door de slechte treinverbindingen kon ik eerst de volgende dag naar Brummen. Daar trof ik een diep verslagen kring van familie en vrienden van UITTIEN. Wij konden het ons nog zo moeilijk realiseren dat wij hem niet weer zouden zien. Eerst nu wij hem voor goed verloren hadden beseften wij in volle omvang hoe groot wel de plaats was die hij in ons aller leven innam. Van nature had UITTIEN weinig belangstelling voor politiek. Hij vond dat hij daar niets van wist en er dus ook niet aan mee behoefde te doen. Hij had dan ook de gewoonte zijn stembiljet blanco, ja zelfs zonder het open te vouwen, weer meteen in de bus te laten glijden, zeer tot ongenoegen van de partij-mannen die bij een dergelijke gelegenheid op het stembureau plegen te zitten. Wel was hij met hart en ziel het Koninklijk Huis toegedaan. Later heeft hij zijn blanco stemmerij opgegeven, daar het hem duidelijk was dat hij op die manier ongewild toch wel eens de door hem toen reeds verafschuwde N.S.B. zou kunnen steunen. De gang van zaken in Duitsland opende hem de ogen en reeds voor de oorlog liet hij zijn antinazi instelling duidelijk blijken. Zo zond hij na de overval van de Duitsers op Tsjecho-Slowakije een paar overdrukjes aan een botanicus in dat land met op het adres: .... Tsjecho-Slovakia, temporarily occupied by Germany. Dit had tot zijn intens genoegen een geheel onverwacht gevolg, n.1. een stroom van overdrukjes van allerlei Tsjechische botanici waarvan hij nog nooit gehoord had. Na de overval op ons land, het bombardement van Rotterdam, dat diepe indruk op hem maakte, en de daarop volgende bezetting, was UITTIEN dan ook een felle tegenstander van Duitsers en N.S.B.ers. Hij uitte dat waar hij kon in woord en daad. Op de Middelbare Koloniale Landbouwschool te Deventer waar hij leraar was, leidde dat tot wrijvingen met een N.S.B.-collega, die alles aan zijn Duitse meesters rapporteerde. Op 31 Aug. 1941, de verjaardag van H.M. de Koningin, kwam het tot een ernstige, maar niet onvermakelijke botsing met de Deventer zwarthemden, vanwege het feit dat hij binnenshuis met een oranjedas rondliep. Zijn huis aan de Dahliastraat werd door de N.S.B.ers belegerd, hetgeen een grote volksoploop en kloppartij tot gevolg had. Korte tijd daarna werd hij wegens dit feit en zijn „tartende” houding tegen de N.S.B.-collega ontslagen. Daar het departement een gunstige wachtgeldregeling maakte was dit geheel tot zijn genoegen. Sindsdien toch kon UITTIEN zich met nog meer energie wijden aan de taak, die hij zich ten bate van de oorlogvoering gesteld had, nl. het bijhouden van een uitvoerig dagboek en het verspreiden van door de radio opgevangen nieuwsberichten en van illegaal uitgegeven geschriften. Het is buitengewoon jammer dat dit dagboek in de laatste oorlogsmaanden door brand verloren is gegaan. Zijn folkloristische neigingen kwamen hem bij het samenstellen van dit dagboek goed van pas. Dagelijks tekende hij alles aan wat hij hoorde. Elk nieuwtje, elk gerucht, elke anecdote, met nauwkeurige opgave van plaats, tijd enz. Hoewel dus alles door elkaar kwam te staan, nl. alleen in de volgorde zoals hij de berichten kreeg, was het toch een verhaal dat men met spanning zat te lezen. Dat kwam natuurlijk ook vooral door de originele wijze waarop hij het gehoorde op schrift stelde. Zijn dagboek zou ongetwijfeld voor de geschiedschrijving van deze jaren van belang zijn geweest. Hoe ver zijn medewerking aan de illegale bladen zich uitstrekte, kan ik niet zeggen, daar hij dat begrijpelijk ook voor zijn familie en naaste vrienden verborgen hield. Wellicht heeft hij wel eens iets in deze bladen geschreven, maar zijn voornaamste medewerking was zeker de verspreiding. Op 29 Januari 1944 werd hij, op grond van verdenking van medewerking aan de verspreiding van „Trouw”, gearresteerd en naar het concentratiekamp Vught overgebracht. Voor zover wij wisten was er echter geen enkel positief bewijs tegen hem. Dat was dan ook waarschijnlijk de reden dat hij zelf dacht vrij te komen. De weinige brieven die hij uit zijn gevangenschap mocht schrijven waren merendeels opgewekt en getuigden van zijn onvergankelijke gevoel voor humor. Helaas werden zijn optimistische gedachten, geuit in zijn laatste brief, niet tot werkelijkheid. Hij schreef daarin dat hij nu wel spoedig dacht thuis te komen. In plaats daarvan werd echter zijn groep plotseling voor een standgerecht gebracht, en niet voor een gewone militaire rechtbank waarop zij recht hadden. De zaken gingen voor de Duitsers in die dagen slecht. De Amerikanen en Engelsen waren in het Westen doorgebroken. Vermoedelijk is er uit Berlijn een bericht gekomen, dat maar weer eens een voorbeeld moest worden gesteld om de schrik erin te houden. Zo werden deze mensen zonder dat iemand iets van de gang van zaken afwist ter dood veroordeeld en gefusilleerd. Weer was op een misdadige wijze met verkrachting van elk begrip van humaniteit en rechtsgevoel, aan 23 landgenoten het leven ontnomen, rouw en verbeten woede achterlatend.

Description: A key is offered to the wood of 35 out of 38 Inga species known from Suriname and the other Guianas. The wood structure indicates that the sections Leptinga, Diadema, Bourgonia and Euinga sensu Bentham are taxonomically sound. Section Pseudinga is unnatural and should be subdivided. The author is in favour of keeping the sections Leptinga and Diadema apart.

Description: Peculiar slit-like apertures in the walls of the fibre tracheids of Dicranostyles mildbraediana described in a previous paper, were recognized by the co-author as the result of a ‘soft-rot’ fungal attack. Consequently these structures are not a characteristic feature of this species.

Description: A small set of bryophytes collected on the islands of Malta and Gozo in April-May, 1968, and April, 1969, by K. U. Kramer and L. Y. Th. Westra (Utrecht) was handed to the author for identification. The results are presented here as a supplement to a paper on the vascular plants of the Maltese islands (Kramer et al. 1972). The collections are deposited in the herbarium of the State University of Utrecht. In the past few years many new data have been published on the bryophytes of the Mediterranean islands, cf. Sunding (1967,1971), Koppe (1965), Lübenau & Lübenau (1970), Düll (1967), Gradstein (1971), and Townsend (1965). The liverwort flora of the Mediterranean coasts is being studied thoroughly by Jovet-Ast & Bischler (cf. 1968). Yet the bryophyte flora of the Maltese islands received very little attention in the literature. A brief survey of the main data follows here.

Description: The chromosome numbers of 85 species of flowering plants from the Canary Islands were determined; 5 of the counts turned out to be new. Notes on some species are given. Numbers deviating from previous counts proved to occur in Polycarpaea divaricata (Pit.) Poir. and Koeleria phleoides (Vill.) Pers. 49 counts are new for the Canary Islands and are listed in table 2.

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

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

Description: The following families are already revised and will be included in Flora Malesiana vol. 4, part 1 which is made ready for the press: Aceraceae, Actinidiaceae s.str., Alangiaceae, Ancistrocladaceae Aponogetonaceae, Burmanniaceae, Geratophyllaceae, Cochlospermaceae, Hydrocaryaceae, Juncaginaceae, Moringaceae, Myoporaceae, Nyssaceae, Philydraceae, Plumbaginaceae, Podostemonaceae Sarcospermaceae, Sphenocleaceae, Stackhkousiaceae, Styracaceae, Trigoniaceae, Zygophyllaceae.

Description: Dr. W. Meijer, who is Dutch-born, worked in Indonesia from 1951 to 1958, first at Bogor, then at Pajakumbuh, Sumatra, and was Forest Botanist in Sabah for several years, revisited Indonesia with a National Science Foundation travel grant under an NSF-AID (Agency for International Development) program for Scientists and Engineers in Economic Development. The University of Kentucky Research Foundation covered part of the travel costs in Indonesia together with the Regional Center for Tropical Biology (BIOTROP) in Bogor, and Weyerhaeuser Timber Co., which is now also financing the printing at U.K. of a guide on trees in Indonesia which should be an excellent tool for better training of foresters in Dendrology (tree knowledge). The Japanese Sumitomo Timber Company also acted as liaison for Dr. Meijer during his visit to East Kalimantan. Dr. Meijer has written a fully documented final report which he hopes to submit to the Indonesian government through its Academy of Science. Parts of the report will be published in the Indonesian Forestry Journal and in International Nature Conservation Journals. He hopes for continuing support from the University, its Office for International Affairs, and the U.K. Research Foundation to get this report published. Officials in the World Bank in Washington D.C. and the Smithsonian Institution have also expressed great interest in the results of Dr. Meijer’s recent mission to Indonesia. The editor is glad to print this preliminary report:

Description: Mr C.T. White is to be congratulated on being presented with, the Mueller Memorial Medal awarded by the Adelaide Meeting of the Australian and New Zealand Association for the Advancement of Science, Aug. 1946. This award is in recognition of his work on the systematic botany of Queensland. Dr Ir J.Ph. Pfeiffer, Director of Research, B.P.M.-lab., Amsterdam, died Nov. 18, 1947, at Amsterdam, 58 years old. He was formerly wood-technologist, and collected plants in Simaloer Island, NW Sumatra.

Description: Bignoniaceae. Dr van Steenis is wording on a revision of the Malaysian Bignoniaceae for Flor. Mal.. Burmanniaceae. Dr F.P. Jonker, Herbarium, & Museum voor Systematische Botanie, Lange Nieuwstraat 106, Utrecht, Holland, is preparing a new revision of the Burmanniaceae for Fl. Mal.

Description: Dr. J.A.R. Anderson, who retired from the Sarawak Forest Service, and now lives at 15 Church Hill, Edinburgh EH10 4BG, will continue his interest in Malesian botany and ecology as a consultant forester and ecologist. The MS. of a project on which he had been working for several years is now in the final stage. This is a ”Check List of the Trees of Sarawak”; the scientific names will be coded and alphabetically arranged by families, genera and species, together with a moderately comprehensive list of vernacular names. This should be of value to the Forest Department in Sarawak. Miss P. Aston, senior botanist at the Melbourne Herbarium, is Australian liaison officer at Kew where she will remain until mid-1974. She is specialized in aquatic plants of Australia on which subject she wrote a most informative book (1973) which will be duly reviewed in this journal.

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

Description: Harold St. John has (in Le Naturaliste Canadien 98, 1971, 571-580) given an evaluation of J.R. & G. Forster plants described in their Characteres generum which is newly dated to have been issued March 1, 1776. We feel induced to correct some inaccuracies. Gingidium montanum (l.c. 574, no. 21) — later transferred to Ligusticum as L. gingidium by Forster f., Prod. (1736) 22; DC., Prod. 4 (1830) 159, as an illegitimate homotypic synonym — is unnecessarily named as a new (superfluous) combination Angelica forsteriana St. John. Hooker f., Handb. New Zeal.Fl. (1867) 97, had this (according to the present Code, art. 72) correctly named Angelica gingidium, as because of the earlier Angelica montana Brot. (1804) he could not use the epithet montanum. For the rest Dawson (New Zeal.J.Bot. 5, 1967, 90) has reinstated the generic name Gingidium. He has still more recently changed the name Gingidium Forst., non Hill (1756), into Gingidia as Hill’s herbal has been said to be declared nomenclaturally valid.

Description: Mr R.E. Holttum, Director of the Botanic Gardens, Singapore, who was on leave in England from July to mid-November, reported that Mr C.X. Furtado has returned to Singapore and is working on the genus Calamus as part of his revision of the Palmae of the Malay Peninsula. Mr Holttum ’aims at getting a revised Flora of the Malay Peninsula written, of which he himself will be responsible for most of the Monocotyledones except Aroids and Palms. Mr M.R. Henderson is working on some families of Dicotyledones. This Flora must be fuller than Ridley’s, and with sufficient introductory matter and illustrations to make it intelligible to the ordinary resident who is prepared to take soms interest in local plants’. Mr Holttum will retire in 1950; he will then devote his time to revise Flora Malesiana, series II, Pteridophyta. Mr Holttum spent a fortnight in Holland, in October, and discussed the contributions to Flora Malesiana which can be prepared at Singapore on the basis of mutual cooperation. Dr A.J.G.H. Kostermans has been appointed Forest Botanist in the Forest Experiment Station, Buitenzorg, Java. He has resumed his studies on the Malaysian Lauraceae.

Description: Flora of Java. Dr C.A. Backer has been working towards the composition of a Dutch-written Flora of Java since about 1903, at first in Java, and onwards of 1931 in Holland. When the war started it was thought safer to mimeograph the MS. as far as it was finished, in order to save the writers’ labours against the chance of complete destruction by bombing or other causes. Prof. Dr H.J. Lam managed to get a number of subscribers and funds for a mimeograph edition. This constitures the ”Nooduitgave” (emergency edition) in which up till now 120 families have appeared in 7 folio volumes. The edition was limited to ca 25 copies. It is the intention to edit 2 volumes more, and then stop it. Circumstances necessitate the printed edition to be written in English to which the author has now consented, and which he will manage himself, Prof. Lam also succeeded in getting a number of temporary cooperators who have assisted Dr Backer in revising some families, viz. Dr A.D.J. Meeuse, A.G.L. Adelbert, and R.C. Bakhuizen van den Brink Jr, whilst the specialists Dr J. Wasscher, Dr S.J. van Ooststroom and Miss Dr G.J.H. Amshoff and the late Prof. Dr B.H. Danser made contributions. She revisions are now nearing completion. Only very few families, mostly sympetalous, are not yet finished. The flora will include the Pteridophytes (more than 500 in Java) and through the consent of Mrs Smith also the Orchidaceae (ca 700!); the latter will be revised on the basis of the MS. revision left by the late Dr J.J. Smith. In the emergency edition practically all synonyms have been omitted for brevity’s sake. It is to be hoped that they will be re-inserted in the scientific edition now aimed at. Endless labours have been spent in identifying the species described under various names, and to a certain extent these synonyms have shaped the specific delimitations and argumentate the present conceptions. They can be omitted in a concise popular flora, but not in the work now prepared. It has taken a long way to reach the present state to account for the flora of Java, but we are sure that the work will certainly be the most valuable contribution towards the flora of Java ever made, as its author possesses an unsurpassed field knowledge combined with a very critical taxonomical point of view.

Description: History. In order to understand its present function, a short historical account is necessary. Bibliotheca Bogoriensis is the oldest science library in Indonesia, established in 1842 at the proposal of J.K. Hasskarl, assistant hortulanus of the ’s-Lands Plantentuin in Buitenzorg, West Java (now called Kebun Raya Indonesia Bogor). The very first 25 books were bought from Dr. Jacques Pierot, a botanist who was sent by the Dutch Government to China. Ever since many visiting botanists left or sold their book collection, the reason why Bibliotheca avails of fine old antiquarian books in the field of botany. Among the library’s treasures are the reprint collection belonging to Melchior Treub with his own hand-written catalogue, as well as his correspondence, and all his awards received from many countries and scientific societies in the world.

Description: We are glad to be able to add to the list of herbaria which have agreed to send on loan herbarium specimens to collaborators of the Flora Malesiana: Herbarium of the Forestry Department, Sandakan, British North Borneo. Mr H.G. Keith, Conservator of Forests is in charge. Herbarium of the Forestry Department, Lae, Territory of New Guinea. Mr J.S. Womersley, Forest Botanist, is in charge (see p. 61).

Description: Dr C.A. Backer is now preparing the MS. on the Orchidaceae for the Flora of Java on the basis of a MS. by the late Dr J.J. Smith. Mr J. Monachino has finished his revision of the genus Alstonia (Apoc.); it is expected to be published early in 1949 in ”Pacific Science”, Hawaii.

Description: It is a great pleasure to announce that the technical difficulties delaying the printing of Flora Malesiana have now been overcome. The first part of volume 4 is in the press and, in all probability, will appear towards the end of this year. Sample sheets of volumes 1, 2, and 3 will be added to the initial instalment of volume 4. Owing to a generous grant by the Netherlands Indies Government of this first issue of the 4th vol. 2500 copies will be printed and distributed to all individual botanists and institutions which are believed to have an interest in the Flora, in order to enable them to form an idea of the scope, execution, and costs of subscription of the work. Those receiving this Bulletin will also receive the initial part. It is expected that volume 1 – which will be issued as one whole – will be in print at the end of this year.

Description: Prom Dr Y. TSIANG, now residing at the Bot. Institute, Sun Yatsen Univ., 30 Fat-Ching Road, Canton, China, we received a set of three volumes published during World War II, all prepared by G. Masumune. They are the following: Enumeratio Phanerogamarum Bornearum. 739 pp. (1942) 1) An attempt to give a revised edition of MERRILL’s Enumeration of 1921. The Introduction and notes under the species are in Japanese characters. The number of genera recorded is 1310, the number of species 7201. Pamilies are arranged in a systematic sequence; an index to family and genus names concludes the volume. In some cases, new combinations are made, e.g. by reduction of Rigiolepis to Vaccinium (Eric.), further in Hanguana, Porterandia, & c. The work has been done rather uncritical: e.g. Styrax agrestis and St. serrulatus are both entered, though ithas been shown that the Bornean record of the latter is wrong and must be replaced by the former species. Peliosanthes albida is both mentioned under Liliacease and Haemodoraceae; Aletris foliolosa is mentioned in Aletris, but A. rigida is entered in Meta-aletris though the two are difficult to distinguish. Nomenclature is not up to date (see Chloranthus, Trema, & c.). A large number of important publications on the Flora of Borneo pubished posterior to 1921 are neglected. The author has apparently far underrated the difficulties in composing a cyclopedia. The latin-written text is full of errors.

Description: ( (Report in the ”Gardens’ Bulletin, Singapore”, vol. XI, pt 4, 1947). Prior to the Japanese attack on Malaya, most of the senior staff of the Gardens were seconded for other duties under the Department of Food Control and Information, for at least part of the time. The result was that botanical work was reduced, and considerable arrears of unnamed and undistributed specimens accumulated. The Gardens were maintained as usual, with the addition of demonstration plots of vegetables.

Description: In 1826 REINWARDT published in ”Sylloge Plantarum” &c, vol. 2, pp. 1-15 under the title ”Nova plantarum indicarum genera” an article containing descriptions of some Malaysian genera of phanerogams. Amongst them is described on pag 1: Angiopetalum punctatum Reinw. n.g.n.sp. from Java. Though assigned to the Myrsinaceae by DALIA TORRE & HARMS this genus has hitherto remained obscure, and has not even been mentioned by MIQUEL. However, there is a name Allopetalum punctatum REINW. mentioned by SCHEFFER (De Myrsin. 1967, 93) as a MS. name in the synonymy of Ardisia pumila BL., also mentioned by MEZ (Pfl. Reich 9 (1902) 171) for that plant, which is now commonly known as Labisia pumila (BL.) B. & H. The type specimens of Allopetalum punctatum REINW. at Leyden (sheets 908.133.- 614 and 903.255 – 190) are undoubtedly the type specimens of Angiopetalum punctatum REINW. The name under which this species was published differs from that found in REINWARDT’s handwriting hut this is of small significance. Many name-changes occur in the materials assembled by KUHL & VAN HASSELT, ZIPPEL, REINWAKDT (and BLUME) whose herbaria were left in BLUME’s care. On the type sheet of Orescia montana REINW. in the same paper of REINWARDT’s I found on the labels the following MS. names: Lysimachia montana BL., Phaemeria montana, Rumeria montana and Lysimachia cuspidata BL, an embarrassing choice from which only the last one has been validly published. In the case of Angiopetalum, REINWARDT who had probably the herbarium not at his disposal copied the name from MS. notes, the herbarium being with BLUME either in Java or at Brussels. Later he hardly paid any attention to phytography or nomenclature.

Description: As was pointed out in the first instalment, the management of Flora Malesiana acknowledge collaborating and co-operating institutions; for this purpose a distinction was made between collaborators and co-operators. The former take an active part in the composition of the work (by revising certain families or large groups), the latter give assistance through the loan of specimens, information about collections, biblographical assistance etc.

Description: In mid-1971 Dr. K. Iwatsuki made a four-weeks’ collecting trip in Thailand, 10 Sept.- 10 Oct. From Oct. 1971 till mid-January 1972 a joint Leyden exploring expedition was made by Mr. C.P. van Beusekom and Mr. R. Geesink to various parts of Thailand.

Description: I must apologize that this Bulletin appears late. Material had been assembled for it and I had anticipated to compose this number about Christmas 1971. But on my birthday, 31 Oct. 1971, it was announced as a complete surprise that the firm of Brill was authorised to publish a book on the Javanese Mountain Flora of which the core is 57 hand-coloured plates on which 456 different species are depicted. The fieldwork was done, and drawings were composed in 1939-1941. After the war no publisher could be found; a precursor with 4 plates appeared in Endeavour (21, 1962, 183-193). The condition attached to this allowance was that I should promise stante pede to deliver the text by end December 1971 or at least as soon as possible, because the promotors of the plan intended to present me with the printed book on the occasion of my retiring from office, 1 Sept. 1972. So the rather peculiar situation arose that I had to make my own present. With my already tight time schedule for my last year of office I hesitatingly agreed. The available text was, however, very incomplete, having been written in the war prison camp, thirty years ago. Moreover it was at that time intended to be very popular for a pocket size atlas, as Schröter’s ’Pflanzenführer fur Alpenwanderer’ which had stood model for the purpose. With the generous life-size plates and folio format book now envisaged to edit, this text had to be completely rewritten in much enlarged scope and all captions carefully checked with the present literature and with the herbarium. Though the plates are explained by the captions, the general text also needed illustration and so figures had to be made or selected and photographs sorted. I had to give this project absolute priority. Notwithstanding the most liberal assistance rendered to me by my senior staff members, to whom I could entrust several time-consuming official duties, the composition of the text was real slave labour for seven days a week until late for five months. The captions were delivered end January, the general text May 22nd. The colour plates are printed and come out magnificently, practically as good as the original water-colour drawings, and the captions are by now in page proof, so that I hope the work will indeed be printed early September and available in October. Publication of Flora Malesiana proceeds well. In April 1971 the third instalment of the Fern volume appeared (Lindsaea-group by Dr. Kramer) and the text for a fourth instalment by Prof. Holttum & Drs. Hennipman is almost finished in MS. The final instalment of vol. 6 is in press and will appear presumably in September. Of vol. 7 the first instalment containing revisions of 12 families appeared in Jan. 1972. The second instalment of vol. 7 is in print (Fagaceae, Passifloraceae) and will appear in autumn. There is the prospect of publishing in the rather near future three very large families: Moraceae, Cyperaceae and Dipterocarpaceae. From the third chapter of this Bulletin it can be observed that progress with revisional work is satisfactory, though speed of publication still falls short of my expectation.

Description: Families and higher taxa have been entered under their name. Names of families which have been revised in volumes 4, 5, 6, and 7 have been entered and are printed in bold type, so that as far as this is concerned this index is complete for all preceding volumes as well.

Description: Small trees, mostly deciduous, bark gummy, wood soft, roots thickened, pungent; trunk often inflated. Leaves spread, imperfectly 2—4-imparipinnate; tissue with myrosin cells; pinnae opposite, provided with stipitate glands at the base of the petiolules and pinnae. Leaflets small, opposite, entire, all articulated. Stipules represented by blunt knobs. Flowers bisexual, zygomorphic, white (or yellow streaked red), in axillary panicles. Calyx tube short, as a hypanthium; lobes 5 imbricate, spreading or reflexed, separately dropping. Petals 5 free, anterior one largest and erect, others reflexed, posterior smallest. Disk lining the calyx tube, with a short free margin bearing the androecium. Perfect stamens 5 epipetalous; anthers dorsifixed, 1-celled, oblong, when lengthwise opened broader. Staminodes 5, subulate, with or without rudimentary anthers. Ovary superior, shortly stalked, 1-celled with 3 parietal placentas. Style filiform, stigma small. Ovules ~, in 2 series on each placenta. Capsule linear, beaked, 3—6-angled; valves thick, spongy, on the inside with pitted cavities in 1 row along the median line. Seeds 3-winged (or exalate), body roundish large. Embryo exalbuminous, straight, containing oil. Distr. Ca 10 spp., confined to the semi-arid countries of Somaliland, Madagascar, SW. Africa, NE. Africa, Asia Minor, 2 spp. in India.

Description: In the past century Cornaceae were mostly delimited in a wide sense and they represented a fairly heterogeneous assemblage. HARMS (Ber. Deut. Bot. Ges. 15, 1897, 28 and in E. & P. Nat. Pfl. Fam. 3, 8, 1898, 255) distinguished 7 subfamilies. Of these Garryoideae were later mostly recognized as a separate family Garryaceae, as Alangioideae Alangiaceae, Nyssoideae and Davidioideae together as Nyssaceae, leaving Cornaceae with the remaining three subfamilies Cornoideae, Curtisioideae (monotypic, South Africa) and Mastixioideae (monotypic, Indo-Malesian tropics). Cf. WANGERIN, Pfl. Reich Heft 414 (1910) 18. In recent years, however, the other genera (6) of the Cornoideae, besides Cornus, have also been recognized as monotypic families, with the exception of Corokia which was transferred to Saxifragaceae-Escallonioideae. Notably TAKHTAJAN (Proiskh. Prokruitosem. Rast.: 89, non vidi) is in favour of these monotypic families. In his ‘Flowering Plants’ (ed. C. JEFFREY; 1969: 227) he accepted 7 segregate families besides Cornaceae sens. str. (omitting mention of two Madagascan genera, one of which he had formerly also raised to family rank, according to SHAW, 1973). These 7 families he arranged, together with Araliaceae and Umbelliferae, in the order Cornales, a phylogenetic construction of affinity not much different from earlier conceptions. The general impression is thus that the distinction of the segregate families is largely an inflation in rank.

Description: Monoecious trees or rarely shrubs, in Mai. evergreen, sometimes buttressed or with stilt-roots; growth mode flushwise, with perular buds. Hairs simple or stellate or fasciculate, rarely with resiniferous colleters, or scales on pits on the underside of the leaf.

In Africa, Fagaceae are confined to the northern rim in the western Mediterranean region. In Asia Fagaceae are absent from the dry parts of the Middle East, from the Deccan Peninsula and Ceylon, from the desert and colder parts of China, from Manchuria, and from the extreme northern parts of Japan. In America, the distribution extends from Canada and the United States southwards to Central America, as far south as a few scattered localities in Columbia, in South America. On the southern hemisphere, Fageceae are present in Malesia, in the scarce wet parts of East Australia, in Tasmania, New Caledonia, and in New Zealand (otherwise absent from Pacific islands); in South America they occur from Fuegia and Staten I. northwards to Argentina and on the western slopes of the Andes in Chile up to 33°S.

Description: Dr. J.A.R. Anderson, Kuching, was on leave in spring 1971; he would return in the middle of the year for a final short tour. Dr. Anderson’s merits for the development of Botany in Sarawak are extremely large; it is a great pity to see such most experienced personalities leave the scene. We are thankful for his important endeavours and wish him a happy retirement. Prof. Dr. C.D.K. Cook, Zürich, is preparing a manual for the identification of aquatic plants.

Description: The Flora Malesiana is not preceded by a general key enabling one to identify any unknown native or wild plant to the family or genus to which it belongs. This is certainly a serious lack and presents a formidable handicap to inexperienced taxonomists in rapid naming current collections. However, there are several forcing arguments for omitting—at present—such an attempt which in itself would present no facile task, and could be accomplished only by a taxonomist thoroughly acquainted with the Malaysian flora. One could of course use some world key as a basis and cut out the entries leading to genera or families not represented in the Malaysian flora, but this procedure would be unsatisfactory, specially as these world keys make little use of vegetative characters; the latter appear to me very important specially in the earlier forks of the keys.

Description: Annual or perennial, unarmed or spinous, bitter herbs or undershrubs, often glandular-hairy. Stem terete, farctate, with a peripheral whorl of air-vessels. Leaves spread, simple, entire, exstipulate.

Riche and F. de Lahaie, naturalists of the voyage in ‘La Recherche’ and ‘L’Espdrance’ in search of La Pdrouse, 1791-1794, collected in Mauritius and Reunion. Part of the plants have erroneously been labelled ‘Java’.

Ca 9 genera and about 600 spp. (Dioscorea large, the other genera small or monotypic). Pantropic with considerable extensions into temperate regions. The Stenomerideae and Trichopodeae are restricted to the warm humid regions where Nepenthes grows and their geologic history must have been that of Nepenthes: they may be regarded as the survivors of the hermaphrodite ancestry of the Dioscoreeae.

Among the remaining 12 one occurs through the Old World (Dolichandrone), 7 are shared with continental SE. Asia (two of which extend also to Africa and Madagascar: Fernandoa, Stereospermum) and 4 with Australia and Melanesia; the latter occur in Malesia only in the east except Deplanchea which ranges westward to Sumatra.

Description: It is not without some pride and much satisfaction that the present volume, fourth planned in the series, second in sequence of publication, is brought to a successful end. Satisfaction I feel through the fact that the scheme and aim of this work is not only understood by the scientific-botanical world, but has also been accepted in the administrative world: Notwithstanding the long term scope of the work, the High Government of the Republic of Indonesia, having realized the essential value of basic scientific work in the natural sciences for the welfare of the future generations of its young nation, has been instrumental in authorizing the Director of Kebun Raya Indonesia (Botanic Gardens of Indonesia, Bogor) to create a Flora Malesiana Foundation. Sponsored by the Indonesian Government, this Foundation knits together the work and interest of the Herbarium Bogoriense of Kebun Raya Indonesia and the Netherlands Rijksherbarium at Leyden, the direction of which have officially agreed to a long-range close co-operation.

Description: For various reasons the space occupied by pre-Linnean Malaysian phytography in this concise history seems too large and out of proportion in comparison to the survey of post-Linnean work. Modern plant description, though based on, and derived from, ancient beginnings and traditions, maintains but slender contacts with plant sciences earlier than the 18th century and it might claim to be allotted by far the larger space on account of its superior results, its greatly increased efficiency, its Consciousness of limitations and capabilities, its output, and its clearness of purpose. There exists, however, during the last decade, an increasing interest in the nearly forgotten botany of centuries long past, not only because of a certain taste for the quaint and attractive flavour of scientific efforts from minds so remote from our own, but also on account of a growing insight into the hidden springs of modern thought and method, which flow deeply, emerge unexpectedly, and appear to rise from distant roots. There is also, in connexion with this, the absorbing spectacle of discovery and of growth i.e. the development of a field of human culture that has bound devoted and excellent personalities in its service from the first glimmerings of our civilization.
