    Bryophytes collected during a Dutch botanical East Greenland expedition to the Angmagsslalik area in 1966 (1968)
    In:  Mededelingen van het Botanisch Museum en Herbarium van de Rijksuniversiteit te Utrecht (2352-5754) vol.304 (1968) nr.1 p.340
    Details
    Publication Date: 2015-05-08
    Description: From a bryological point of view Greenland is not well known in detail. Unlike Siberia or Arctic America, it is not known through a few large collections, but through multitudes of mostly relatively small gatherings. In this arctic island that is almost 2000 miles long and extends from below 60° N.lat. to nearly 84° N.lat., travel and logistics are difficult. Consequently no over-all study of the whole island has been made, although many collections have been achieved through casual or intensive studies of small areas. Like the other contributions to the knowledge of the bryoflora of Greenland this paper will only deal with a rather limited area; the Angmagssalik district on the East coast of Greenland, ranging from 65° N.lat. to 67°20' N.lat. In 1887 Lange and Jensen published the first and until now the only comprehensive review of specimens and publications on the Musci of Greenland. In their paper the first moss collection from the Angmagssalik area was reported, made in 1884-1885 in the course of ethnographical studies by Gustav Holm (Sphagnum girgensohnii and Polytrichum juniperinum), the first European to visit this part of East Greenland.

    Taxonomy and pollen morphology of the Caltha leptosepala complex (1969)
    In:  Mededelingen van het Botanisch Museum en Herbarium van de Rijksuniversiteit te Utrecht (2352-5754) vol.312 (1969) nr.1 p.16
    Details
    Publication Date: 2015-05-08
    Description: Contrary to Europe, with only one Caltha species, North America has at least three species of this genus. These are the polymorphic C. palustris L., also widely distributed in Europe, the floating aquatic C. natans Pall, and the polymorphic C. leptosepala-biflora group. Two previous papers (Smit 1967, 1968) dealt with taxonomic aspects of C. palustris, that in North America were not essentially different from those of European material.

    Fundamentele vragen van de bijzondere plantkunde en de plantengeografie (1950)
    In:  Mededelingen van het Botanisch Museum en Herbarium van de Rijksuniversiteit te Utrecht (2352-5754) vol.98 (1950) nr.1 p.1
    Details
    Publication Date: 2015-05-08
    Description: Zeer geachte Toehoorderessen en Toehoorders, Bij het beginnen van een wetenschappelijk onderzoek zal meestal degene die zich daaraan gezet heeft, allereerst het antwoord dienen te vinden op enkele fundamentele vragen. Zijn deze primaire vragen beantwoord, dan is de weg gebaand voor verder onderzoek en voor algemene theoretische beschouwingen. Deze fundamentele vragen zijn echter niet voor elke onderzoeker en ook niet voor elk onderzoek in een zelfde tak van wetenschap steeds gelijk. Dit hangt af van vele factoren, zoals: uiteindelijk doel van de studie, aard van het materiaal, geaardheid vooral van de onderzoeker, enz. Vandaag wil ik met U behandelen de hoofdvragen, die zich bij mij, voor de aan mij toevertrouwde onderdelen van de botanie steeds op de voorgrond plaatsen en de wijze waarop ik die beantwoorden pleeg te interpreteren voor het verdere onderzoek. Hierdoor zal ik tevens de gelegenheid hebben, om aan te stippen in welke richting wij op het gebied van de bijzondere plantkunde en de plantengeografie nog onderzoekingen kunnen verrichten, die ons inzicht in het geheel aanmerkelijk kunnen verruimen. Voor ik met mijn eigenlijke onderwerp begin, moet ik toch iets zeggen over wat „bijzondere plantkunde” is. Ik zal er niet te veel over uitweiden, daar, zoals Koningsberger en Reinders in het voorwoord van het eerste deel van het Leerboek der Algemeene Plantkunde terecht opmerken, de scheiding tussen „algemene” en „bijzondere” plantkunde uiteraard onscherp is. Volgens de letter van de gebruikelijke terminologie zou eigenlijk alles wat niet „algemeen” is thuis horen onder de bijzondere plantkunde. Zover wil ik niet gaan, want dat zou mijn taak wel heel omvangrijk maken en afgezien van het feit dat het buiten mijn kunnen zou komen te vallen, denk ik ook dat mijn collega voor de algemene plantkunde ernstige bezwaren zou maken indien ik datgene van de plantenphysiologie dat zeker niet algemeen is te noemen, voor mijzelf zou gaan opeisen. Ik wil daarom beginnen de physiologie, hoe bijzonder deze hier en daar ook moge zijn, maar onmiddellijk in zijn geheel bij de algemene plantkunde te plaatsen. Voor de rest zou ik mijn bovengenoemde definitie, dus „bijzonder” is alles wat niet „algemeen” is, in grote trekken willen volgen, met dien verstande dat ik mij natuurlijk wil houden aan de veelal gebruikelijke taakverdeling, zodat b.v. de „algemene” morphologie en anatomie van de Angiospermen, die in feite in het plantenrijk als geheel, „bijzonder” is, bij de „algemene plantkunde” wordt ondergebracht. De speciale en vergelijkende morphologie van deze groep reken ik echter zeer zeker tot de mij toegewezen tak van wetenschap. Ook de afgrenzing met de genetica is niet scherp. Indien men elk onderzoek waarbij niet uitsluitend op het phaenotype maar ook op het genotype gelet wordt, tot de genetica wil rekenen, dan zal de betrekkelijk jonge experimentele plantensystematiek of biosystematiek geen deel kunnen uitmaken van de bijzondere plantkunde. De genetici zullen het mij wel niet euvel duiden, dat ik ook deze tak van onderzoek laat staan bij de bijzondere plantkunde, waaruit zij is voortgekomen en waarvoor zij van zoveel betekenis is.

Seven genera (Scabratisporites, Guttatisporites, Lapposisporites, Pseudogravisporites, Paralundbladispora, Taeniaepollenites and Tubantiapollenites) and 39 species are new; three generic descriptions are emended (Apiculatasporites, Colpectopollis and Angustisulcites) and three new combinations are proposed. Bisaccate pollen grains average 84 %; within this group no Upper Permian elements could be demonstrated. The assemblage is compared with other European Lower and Middle Triassic assemblages; there are no close similarities to assemblages outside Europe.

    Description: Dames en Heren, In een universitair blad kwam onlangs de mededeling voor, dat aan een hoogleraar, die zich in dezelfde moeilijkheid bevindt als ik, nl. dat hij in de loop van deze cursus 70 jaar is geworden, een afscheidscollege zou worden aangeboden. Ik vond dat een sympathiek plan. Als men met college geven, ondanks de daaraan verbonden bezwaren, de 70-jarige leeftijd heeft gehaald, is het werkelijk geen overbodige weelde dat een ander de taak voor deze laatste keer van hem overneemt.

    A palynological study in Geonomoid palms (1966)

    Description: In a previous palynological study in Cocoid palms the present authors (Punt and Wessels Boer, 1966) were able to demonstrate a rather strong but not absolute correlation between the pollen types and the staminate flower types within the genus Attalea in the broad sense. The existence of partly apparently primitive, partly very advanced flower types within the otherwise close related group of Geonomoid palms made it worthwhile to investigate the same feature in this group. The Geonomoid palms are usually considered to comprise 7-9 genera of monoecious Arecoid palms which share a large number of characteristics (Burret, 1930; Moore, 1966). The group is very obviously a most natural one. The generic distinctions are mainly based on the flower morphology, notably on differences found in the androeceum and pistil.

    Description: It is the fate of most historic personalities that in the course of time their work sinks almost completely into oblivion, and that the few lingering reminiscences of their achievements are transmitted to later generations in the form of second- or third-hand quotations, usually mixed with more or less anecdotic episodes from their life. It must be admitted that LINNÉ occupies in this respect a comparatively favourable position, for most educated people will remember that they heard in their school days of at least three things which are credited to him, in the first place that he produced a classification of the plant kingdom which is based on the number of stamens and carpels, the so-called sexual system, in the second place that he was the first who consistently applied the binomial nomenclature, i.e. the custom to designate an organism by a combination of two names, viz. a generic and a specific one, and thirdly that he was the originator of the pronouncement “Species to numeramus quot diversae formae in principio sunt creatae” (We count so many species as in the beginning different forms were created). Other achievements of LINNÉ may have been of greater importance, but it are these three things for which he is most generally remembered. The pronouncement quoted above, which means that the groups of individuals which form the species are descended from ancestors that owed their origin to an act of creation, derives its historic importance from the part it played in the debates on the theory of evolution. As it implies that the species are constant, it became the watchword of the antagonists. It is, however, rather strange that this pronouncement has so often been quoted, for it is found in LINNÉ’s earlier works only, and was in the later ones replaced by another statement that flatly denies the constancy of the species.

    Description: Erismadelphus Mildbr. is remarkable because it is the only African genus of the Vochysiaceae, a family represented in tropical America by no less than 5 genera and 180 species. Erismadelphus was discovered in 1913 by Prof. J. MILDBREAD and has hitherto been represented by only one species: E. exsul Mildbr. Recent examination of the African collections has, however, revealed the existence of two other taxa. Unfortunately the type of E. exsul (Mildbraed s.n. from Elon, French Cameroons) was destroyed at Berlin during the 1939-45 war and no duplicates or cotypes are known to exist. In response to an enquiry Prof. MILDBREAD, to whom we are very grateful, informed one of us that in his view Corbisier 1362 from Eala in Belgian Congo was identical with his original type. Prof. MILDBRAED and KEAY have, in fact, together examined Corbisier 1362 in the Herbarium of the Jardin Botanique de l’Etat at Bruxelles through the courtesy of Prof. ROBYNS. Duplicates of Corbisier 1362 are at Kew and Paris, they agree in every respect with MILDBRAED’s original description and figure and we therefore propose that this specimen be adopted as the neotype (lectotype).

    Description: The water economy, the mineral content of the soil, and human influence are the principal ecological factors governing the variation of the heath vegetation of a limited region. Sloping of the surface is also an important factor. In hilly country it is of a twofold nature: on the one hand the difference between high and low altitudes, based on the water economy, on the other hand differences in (micro-) climate. If the hills are higher, this results in greater climatic differences. In extremely oceanic and in boreal regions a rise in altitude of 100 m is sufficient for creating a noticeable decrease in temperature and an increase in precipitation, aerial moisture, and wind force. This results in the occurrence on the hills of heath communities that have their main distribution more to the North. The same observation was made by Gimingham (1961). On Slieve League on the Donegal coast (Ireland) Salix herbacea and Lycopodium selago occur in the heath at an altitude of 600 m, near Tongue on the Scottish north coast Dryas octopetala, Saxifraga oppositifolia, Alchemilla alpina and Thalictrum alpinum at an altitude of 60 m. West of Apeldoorn in the Netherlands are found extensive stretches of heath with abundant Vaccinium myrtillus and V. vitis-idaea at an elevation of 60-80 m, even on south-facing slopes. This is an area with high precipitation due to ascending air west of the hill ridge of the Eastern-Veluwe. Here the Vacciniums, elsewhere requiring the protection of the forest, can tolerate the habitat of the open heath (Stoutjesdijk, 1959; De Smidt, 1966). Higher elevation combined with north-facing slopes creates extreme conditions e.g. on Roc Trévézel (300—360 m) in Brittany, with Vaccinium myrtillus, Melampyrum pratense, Hymenophyllum wilsonii and Rhytidiadelphus loreus. These species are virtually lacking in the surrounding plains where the heath consists of such South Atlantic species as Erica cinerea, E. ciliaris, Ulex gallii, Lobelia urens, Lithospermum prostratum and Symethis planifolia.

    Description: Although algology deals with a large group of plants, widespread and of a great morphological diversity, the history of this branch of botany is fairly young. Linnaeus (1753) listed in his Species Plantarum under the heading “Cryptogamia—Algae” only five genera of plants which are still accepted as algae at the present time. Under the same heading he also described a number of liverworts, lichens and sponges and a few other things.

    Study of a peat profile on the Frisian Coast of the former “Zuiderzee” (1952)

    Description: The subject of this study are soil samples taken in the “Makkumer Waard”, a wide expanse of low-lying land, which follows the Frisian coast. Stratigraphical and palynological investigations showed that in the beginning of the Atlanticum the area lay below the level of the sea, but that gradually the influence of the sea decreased and peat formation became possible. From the transition from marine deposits to Sphagnum peat (— 4,55 m to — 3,50 m) we must conclude that there has been a temporary standstill in the transgression, or even a regression, in the middle of the Atlanticum. Towards the end of the Atlantic period a sudden marine transgression followed, which deposited a layer of sand and clay on the Sphagnum peat (— 3,50 m to — 3,30 m). Shortly before the beginning of the Subboreal (which probably sets in at — 3,10 m) an important regression began and an Eriophorum peat was formed directly on the clay (—3,30 m to —3.00 m). It is probable that the peat formation went on in the Subatlanticum, but the younger Sphagnum peat is no longer present, for a third marine transgression, which lead to the formation of the “Zuiderzee”, washed away the peat and deposited the younger sea sand. The data obtained from the Makkum profile proved to agree very well with the results of other investigators who worked in the area round the North-sea.

    Description: Previously, the chromosome numbers of some species of Loganiaceae were dealt with (Gadella, 1961, 1962, 1963). The chromosome numbers of 7 species are reported in this paper, of which 4 species, all belonging to the genus Strychnos, had not been investigated cytologically before. The materials, kindly supplied to me by Dr. A. J. M. Leeuwenberg and by Ir. F. Breteler, were collected in the form of seed-samples in the Ivory Coast and in Cameroun. The plants of 2 species originate from botanical gardens. Living material of all species (except for Strychnos lernata Gilg. ex Lwb.) is grown in the botanical garden of Wageningen (WAG). The determination of the chromosome numbers was based on the study of roottipmitoses. Roottips of the plants were fixed in Karpechenko, embedded in paraffin, sectioned at 15 micron and stained according to Heidenhain’s haematoxylin method. The results may be summarized as follows: 1. Nuxia floribunda Benth.: 2n = 38 Origin of the material: S. Africa, obtained from the University of Stellenbosch. Seeds probably collected in the wild. Herbarium material of the mother-plant: J. J. Bos, no. 310 (WAG). Herbarium material of seedling: A. J. M. Leeuwenberg no. 3665 (WAG). References: Gadella (1963): 2n = 38. 2. Strychnos dinklagei Gilg.: 2n = 44 Origin of the material: Ivory Coast, Forêt d’Abouabou, between Abidjan and Grand Bassam. Herbarium material of the mother-plant: R. A. A. Oldeman no. 845 (WAG). Herbarium material of the seedling: A. J. M. Leeuwenberg no. 3561 (WAG). References: Gadella (1963); 2n = 44. 3. Strychnos innocua Del. subsp. innocua: 2n = 44 Origin of the material: Ivory Coast, 16 km S. of Ferkéssédougou. Herbarium material of the mother-plant: A. J. M. Leeuwenberg no. 4435 (ABI, WAG). 4. Strychnos millepunctata Leeuwenberg: 2n= 441) Origin of the material: Ivory Coast, Forêt d’Abouabou, between Abidjan and Grand Bassam. Herbarium material of the mother-plant: J. J. F. E. de Wilde & A. J. M. Leeuwenberg no. 3447 (ABI, WAG). 5. Strychnos samba Duvign.: 2n = 44 Origin of the material: Cameroun, 4 km S. of Nguélémendouka. Herbarium material of the mother-plant: F. J. Breteler no. 2051 (WAG). 6. Strychnos spinosa Lam.: 2n = 44 Origin of the material: obtained from the botanical garden of Groningen, the Netherlands, origin unknown. Herbarium material of cutting: A. J. M. Leeuwenberg no. 3564 (WAG). References: Mangenot and Mangenot (1958): 2n = 44. Miège (1960): 2n = 44. Gadella (1962): 2n = 44. 7. Strychnos ternata Gilg. ex Leeuwenberg: 2n = 44 1) Origin of the material: Cameroun, 27 km from Bertoua on road to Bétaré Oya. Herbarium material of the mother-plant: F. J. Breteler no. 2196 (WAG). Herbarium material of the seedling: F. J. Breteler no. 2994 (WAG). Twenty-one species of the genus Strychnos have been studied up to the present. The following chromosome numbers have been counted: 2n = 24 (3 species, counted by Mohrbutter, 1936); 2n = 44 (16 species); 2n = 88 (2 species). From these data the conclusion may be drawn that the more common basic number of the genus Strychnos is X = 11 or 1 = 22.

    A reassessment of the Cyphellaceae (1966)

    Description: A suitable subtitle for this paper would have been “The rise and fall of a family”. What is usually called the Cyphellaceae is an instructive example of a situation not uncommonly encountered in the current systematics of mycology: a family retained in a traditional sense by some mycologists and considered by them as good a family as any, while others are convinced that it is nothing but a handy bin from which part of the contents has already been taken out and disposed of by scattering it over various groups, but which is still needed for keeping what remains. We do not yet know what to do with this considerable remainder, mainly because the published accounts are inadequate and the species have not yet been scrutinized anew in the light of present-day taxonomic requirements. In order to understand the basic idea of the Cyphellaceae the type species may be briefly introduced. The fact that Cyphella digitalis was originally described as Peziza digitalis is telling, and one could not do better than characterize it as a ‘discomycete’ with basidia, viz. a cup-shaped fruit-body with the hymenium lining the smooth inside or ‘disk’. If one were pressed to form an opinion about its taxonomic position from a dried, not annotated collection and without the aid of the microscope, one would even now, very likely, dispose of it as a discomycete. However, there is little doubt that in nature the cup is directed downward at least when mature, in contradistinction to the average discomycete in which the hymenium containing the asci is directed upward. This difference is a reflection of the two modes of violent spore discharge inherent in the hymenomycetous basidium and ascus; it has been explained through Buller’s well-known researches. The cups in the various species are not always typically cup-shaped; in a number they are more or less tubular or else more flattened and even disk-like.

    Two questions about mass selection in Connecticut Shade Tobacco (1967)
    In:  Mededelingen van het Botanisch Museum en Herbarium van de Rijksuniversiteit te Utrecht (2352-5754) vol.242 (1967) nr.1 p.512

    Description: From the general discussion of the effect of mass selection on the genotypic array of the next generation we have seen that under certain conditions mass selection can lead to homozygosity, but does not do so necessarily. Outcrossing, mutations and disadvantages of certain genotypes may prevent reaching equilibrium condition with complete homozygosity even in the simplest case of one locus with two alleles. It depends on the magnitude of these factors and the degree of heterozygosity of the variety how close to genetic uniformity we ultimately can come. The advancing of one generation has only a small effect, which becomes less as the frequency of one of the genotypes becomes less. Mass selection can reduce segregation in a variety, but only in ideal situations and only in small steps. Obviously the most effective way to promote genetic uniformity is to begin with non-segregating material obtained through careful inbreeding and within-family selection. Then, if this is available, mass selection is hardly necessary and seed collection should be done so as to prevent a return to a heterozygous condition. When only segregating populations are available, some changes can be expected if the selection intensity is low, but they will not be great and may not be noticed until after several generations. Returning to the original question of the stability of the tobacco variety, the conclusion can be drawn that when large numbers of plants from a field are selected as seedplants the changes in the next generation as a whole will be small, regardless of the selection procedure used. When 10-30 % of all plants are allowed to produce seed we cannot expect important changes. Also, when the environmental variations are as great as in shade tobacco, the possibilities of selecting against certain genotypes for a number of characteristics simultaneously becomes virtually impossible. Concerning whether or not mass selection can lead to improvements in the variety, it was explained that the selection intensity and the heritability of a character determine the selection response. Perhaps this response can be predicted in the case of one character, but it becomes difficult, if not impossible, to forecast the results when many characters are involved at the same time. Reference was also made to a selection index which has been effective in livestock breeding. Even if an index could be determined for shade tobacco, its use is not necessarily effective, as Kempthorne (1957) pointed out. The genotype-environment interaction makes questionable the choice of certain fields over others. Without experiments, such questions cannot be answered. It is likely that mass selection with low selection pressure changes a variety very little. Again, in a field where up to 30 % of the plants are selected for seed, the pressure cannot be very great and we should not expect great changes. Only when a few plants are carefully selected for certain characters should progress become noticeable, as is the experience of single plant selection in plant breeding. We conclude that mass selection for seed and plant breeding to improve a variety should not be confused with each other. Each has its own aims and methods, which are not interchangeable. Where uncertainty exists about seed, progeny tests usually are made to compare a seed with the parent seed. Bolsunov (1959) has described a number of such procedures for tobacco, though the more elaborate of them appear impractical.

    Notes on Guiana Myrtaceae III (1950)

    Description: What KIAERSK wrote in 1893 in the preface of his “Enumeratio Myrtacearum Brasiliensium” is still largely valid. It is often most difficult to define a species belonging to this family, not only because, in the absence of ripe seeds, the genus is not easily ascertainable, but also because of the strong variability shown by the vegetative characters. Thanks to the examination of the rich Guiana material preserved in the herbaria of Genève, Kew, Leiden, New York, Paris and Utrecht, I have usually been able to delimit the species in a satisfactory way; their allocation to a definite genus, however, is often a difficult problem. During the preliminary stage of this investigation, which was interrupted by the war, it was of great advantage to me that I could study the Guiana specimens of the Leiden herbarium. In order to avoid misinterpretations, I have tried to base my conclusions as far as possible on an examination of either the types themselves or of duplicates of the latter. Several of these types, especially those that form part of the earlier collections of Guiana plants, e.g. of the collection Aublet, and of the collections Desfontaines (herb. Florence) and De Candolle (Genève) had never before been reexamined, and BERG, the last monographer of the South American Myrtaceae (in Linnaea XXVII (1855—56), XXIX (1858) and XXX (1861) has either neglected these species or given an, often incorrect, interpretation based on the description alone. For this reason the second part of this paper will be devoted to a short survey of these earlier types. My best thanks are due to the directors of all herbaria mentioned. Moreover, I have to thank the “Van Eedenfonds”, whose financial aid enabled me to pay a visit to Kew and to the British Museum.

    Description: Eén van de grote giften van A. A. Pulle, Lanjouw’s voorganger als Hoogleraar in de Bijzondere Plantkunde en de Plantengeographie te Utrecht, was zijn goede keus van medewerkers. Hij kon die keus maken dank zij een andere gift, die van leermeester. Pulle’s stimulerende activiteit als hoogleraar luidde de wedergeboorte in van de Nederlandse plantensystematiek door een stroom van leerlingen waarvan er velen ook nu nog een belangrijke rol spelen in de botanische wereld. Vele van Pulle’s leerlingen uit de eerste tijd moesten Utrecht verlaten omdat er in de twintiger jaren nu eenmaal nog geen sprake was van een redelijk gesalariëerde wetenschappelijke staf. Eén leerling echter werd zo gefascineerd door de vele mogelijkheden die het Utrechtse instituut bood, dat hij bleef, niettegenstaande de soms zeer ongunstige economische en organisatorische omstandigheden. Deze leerling, Lanjouw, toonde reeds toen de taaie volhardendheid die zijn medewerkers en leerlingen in later jaren zo goed leerden kennen en waarderen. Reeds van de eerste jaren van zijn assistentschap aan stonden Lanjouw de idealen voor ogen die hij in de loop van zijn lange loopbaan van assistent tot directeur voor het grootste gedeelte zou weten te realiseren. Deze loopbaan begon toen hij op 1 januari 1926 benoemd werd tot assistent bij de Bijzondere Plantkunde. In het jaar waarin we het feit herdenken dat het veertig jaar geleden is dat Lanjouw verbonden werd aan het Botanisch Museum valt ook de honderdenvijftigste verjaardag van het herbarium. Plantensystematiek is te Utrecht in meerdere of mindere mate beoefend van de stichting van de Universiteit af. Op 30 oktober 1816 echter werd het eerste herbarium voor de Universiteit verworven. In 1966 herdenken we dus eigenlijk twee jubilea. De periode van werkelijk actief systematisch onderzoek is echter veel korter geweest: de korte jaren van Miquel’s werkzaamheid (1859-1871) en de periode die in 1906 begon met de aanstelling van Pulle tot Lector in de plantensystematiek. Pulle gaf, voor het eerst na Miquel, en mede dank zij de stimulerende invloed van Went, een nieuwe stoot aan het plantensystematisch onderzoek in Nederland en wel vooral aan het onderzoek van de tropische flora’s. Een reeks van leerlingen wijdde zich onder zijn leiding aan de studie van de flora’s van Suriname en Nederlands Indië. Het is voldoende hierbij de namen van van Sloten, Lam, van Steenis, en Uittien te noemen om deze ontwikkeling te illustreren. Lanjouw koos voor zijn proefschrift de Surinaamse Euphorbiaceae en het was uit dit werk dat de „Flora of Suriname” voortkwam. Zonder ook maar iets tekort te doen aan de rol van Pulle kan gezegd worden dat van het begin van zijn loopbaan af Lanjouw actief heeft medegewerkt aan de opbouw van het Botanisch Museum en dat hij bij de ontwikkeling van de zo belangrijke „Flora of Suriname” een doorslaggevende rol heeft gespeeld. Zijn dissertatie „The Euphorbiaceae of Suriname” vormde, ten dele, tegelijk de eerste aflevering van de Flora.

    Bistella Adans. versus Vahlia Thunb. (Vahliaceae) (1966)
    In:  Mededelingen van het Botanisch Museum en Herbarium van de Rijksuniversiteit te Utrecht (2352-5754) vol.229 (1966) nr.1 p.84

    Publication Date: 2015-05-08
    Description: The somewhat peculiar genus Vahlia Thunb. (1782) was formerly regarded as an anomalous member of the Saxifragaceae, but in 1959 it was segregated as the monotypic family Vahliaceae by Dandy (in Hutchinson, Fam. Fl. Pl. ed. 2, 1: 461). The genus includes about three species, all of them highly variable in stature, flower size, and indumentum; this has resulted in the description of more than twenty “species”, whose names now appear in synonymy. This note, however, is chiefly concerned with the generic name, since it appears that Vahlia Thunb. is not correct under the Code and must be replaced by Bistella Adans. (1763). In the synonymy under the new combinations, all the relevant names so far traced are included, but it may well be that an experimental approach to the problem of specific and infraspecific limits and the taxonomic value of the characters hitherto relied upon for differentiation would result in considerable changes. Bistella Adans. (1763) was cited in the form “ Bistella Lippi 243 – Ascyroides Lippi” and the name than fell into abeyance until it was resuscitated by Delile in 1826. He described plants collected by Cailliaud, and identified a number of them with those of Lippi. In particular, he identified Lippi 243 (and 244) with the Cailliaud plant which he named “ Bistella geminiflora Delil. (Descript, des plantes découv. par M. Cailliaud, pl. II. fig. 4). – Ascyroides Lippi (Manusc. nos. 243 et 244).” It must be emphasized that the taxonomic identification of “ Bistella Del.” with Vahlia Thunb. has never been questioned, but the identity of Adanson’s Bistella with Bistella geminiflora Del. has been overlooked; this species, as represented by Lippi’s plant, is the type of the generic name Bistella Adans.

    The genus Mathewsia (Cruciferae) (1966)
    In:  Mededelingen van het Botanisch Museum en Herbarium van de Rijksuniversiteit te Utrecht (2352-5754) vol.232 (1966) nr.1 p.102
    Details
    Publication Date: 2015-05-08
    Description: Among the endemic and sometimes localized genera of the Cruciferae occurring in South America, Mathewsia stands apart as an element of the distinctive desert flora of southwestern Peru and western Chile. As far as present records show, the genus is confined to a relatively narrow strip wholly west of the main Cordillera, not far from the Pacific Ocean. Some species are confined to washes or small arroyos known as quebrades. Others occur as part of the lomas vegetation of western Peru. Populations of the same species occupying different quebradas often differ from each other to a limited degree and in many instances probably little or no gene exchange occurs between them. The intervening dry areas, separating one quebrada from another, are completely unsuited to the growth of Mathewsia and form a natural barrier to the spread of any given population. Thus, with habitats only spottily available, the evolutionary divergence that has resulted in localized species of Mathewsia is readily understandable. One of the real difficulties in studying a group of species inhabiting areas that have been infrequently visited by botanists, is the paucity of available material. Furthermore, unlike some species of Cremolobus (Khanna and Rollins, 1965), the numbers of individuals in a given locality appear to be few and scattered. In some instances, only a single specimen of a given species has been found for study in all of the herbaria consulted. Under these circumstances, the bare essentials of the species are all that can be given and nothing can be said about their variation or distribution. The purpose of this paper is to present, as a first approximation, a taxonomic treatment of Mathewsia that will provide a sound basis for further research on the genus.

    Description: Among the material collected by LANJOUW and LINDEMAN during the Suriname Expedition 1948—’49 a specimen of Mabea taquari Aubl. was found whose flowers showed some interesting deviations from the normal structure. In the “Flora of Suriname” vol. II, part 1 (1932), p. 78 LANJOUW states that the female flower of the genus Mabea Aubl. is apetalous and provided with a 5- or 6- partite calyx. In a re-investigation of the specimens preserved in the Utrecht Herbarium this could as a rule be confirmed.

    Description: The pollenflora of the browncoal mined in the quarry “Maria Theresia”, Herzogenrath, Western Germany has been investigated. Samples were taken along a section of 12.50 meters at intervals of 50 centimeters. Identifications were made on the basis of form-genera and form-species; this working method gives a broad information on pollen types, but does not relate the fossil pollen types primarily to recent plant taxa. Pollen types which are considered to belong to Betulaceae/Myricaceae make up the biggest part of the pollen assemblages. The construction of a “Composite diagram” for Betulaceae/Myricaceae proved to be useful and might give a better idea on paleoecologic conditions. The stratigraphic position of the browncoal examined is thought to be Lower “Hauptflöz”, possibly Morken or Frimmersdorf Horizont.

    Chromosome numbers of Parnassia palustris L. in the Netherlands (1965)

    Description: In Sweden Erlandsson (1942) showed that the species Parnassia palustris L. has two chromosome numbers, 2n = 18 and 2n = 36. Rozanova (1940) found the same numbers in plants collected in the U.S.S.R. Some morphological differences could be demonstrated in the Swedish material (Erlandsson, 1942). This was confirmed by Löve and Löve (1944) and, therefore, these authors (1950) distinguish 2 species: the diploid Parnassia palustris L. em. Löve and the tetraploid Parnassia obtusiflora Rupr. em. Löve, also separated by sterility barriers and by their geographical distribution. In the Netherlands a tetraploid population was found by Gadella and Kliphuis (1963). As the tetraploid population occurs in an area situated far south of the circumpolar distribution area of the tetraploid plants, it seemed worthwhile to determine the chromosome numbers of other plants of Parnassia palustris L. growing in the Netherlands.

    Description: Les systèmes radiculaires des espèces des prés salés du Juncion maritimi ont été étudiés. Nous avons distingué six types morphologiques principaux d’enracinement. Les particularités des différents types et espèces ont été décrites et dessinées. La répartition des différents types d’enracinement dans le Junco-Triglochinetum et le Caricetum divisae a été interprétée écologiquement. Les racines de nombreuses espèces du Juncion maritimi sont pourvues de lacunes aérifères. C’est une adaptation au niveau élevé de la nappe phréatique. La résistance mécanique du sol a également une influence sur le système radiculaire. La concurrence des systèmes radiculaires a été discutée. On a essayé de différencier les groupements végétaux par leurs types d’enracinement. Je tiens à remercier M. J. Braun-Blanquet, directeur de la Station Internationale de Géobotanique Méditerranéenne et Alpine à Montpellier, de son aide et de l’intérêt stimulant qu’il a porté à mon travail, et M. J.-M. Betsch de son conseil. Les subventions de la Koninklijke Nederlandse Akademie van Wetenschappen (Montpellier fonds) et du Utrechts Universiteitsfonds m’ont facilité le séjour à la Station et rendu possible ces recherches.

    A sketch of the vegetation and flora of the Kappel Savanna near Tafelberg, Suriname. I (1968)

    Description: In February and early March, 1961, the senior author spent three weeks on a small savanna in the approximate centre of Suriname, South of Tafelberg, (map 1). He was accompanied by Mr. W. H. A. Hekking. The time was spent in exploring the flora of the savanna and the adjacent forest. As a detailed study of the vegetation of the savannas of northern Suriname was then in progress, several extensive papers being in preparation (Heyligers, 1963; Van Donselaar, 1965; Van Donselaar-Ten Bokkel Huinink, 1966), it was felt that a more thorough inventory of the vegetation and the flora of the savanna might be rewarding. When a general impression of the plant-cover of the area had been obtained, eight representative sample-plots were selected, their vegetation was analyzed and described after the method of the French-Swiss school of phytosociology, and pits were dug in the soil down to bedrock, samples being taken in every distinctive-looking layer. This work was carried out jointly by the senior author and W. H. A. Hekking; part of the floristic exploration was also done by or with Dr. R. M. Tryon, Harvard Herbarium, Cambridge, Mass. The results are here presented. It was felt that in order to integrate them with those obtained elsewhere in Suriname, the collaboration of a specialist familiar with the Suriname savannas in general was required. This was the junior author’s task, who, after his prolonged work on the savannas of northern Suriname, later expanded his work to those of the southern part of the country. The preliminary results of the last-named study are in the press; more detailed field work is in progress as this paper goes to the press.

    Stevens Pond: A postglacial pollen diagram from a small Typha Swamp in Northwestern Minnesota, interpreted from pollen indicators and surface samples (1967)
    In:  Mededelingen van het Botanisch Museum en Herbarium van de Rijksuniversiteit te Utrecht (2352-5754) vol.276 (1967) nr.1 p.145

    Description: The pollen assemblages of a core in the coniferhardwood formation in northwestern Minnesota are compared with the floristics of the recent vegetation in the region. Percentage levels of the main tree components have been compared first with those from recent surface samples taken at the same short distance from various types of upland forests and second with the regional values of the pollen rain in this area (McAndrews 1966). To that end all the data were recalculated on the basis of special pollen sums. The regional diagram of Stevens Pond shows basically the same assemblage zones as established by McAndrews but without the late-glacial Picea-Populus assemblage zone. The pollen in the following Pinus-Pteridium assemblage zone has been interpreted as derived from a pine forest. During the midpostglacial expansion of the prairie eastwards the regional vegetation must have been a Quercus savanna, locally with prairie. Corylus reaches relatively high percentages in this zone. Among the prairie elements especially the occurrence of Lilium philadelphicum may be noted. In the next zone the pollen diagram shows a rise of the curves of mesic elements. In spite of this the comparison with recent surface samples indicates a xerophytic Quercus forest rather than a mesophytic deciduous forest. In the following Pinus assemblage zone pine was present along the margin of Stevens Pond and is therefore overrepresented in the diagram. In the uppermost zone the pollen curves show the effect of logging of the forest about 1900. Pollen of cultivated and introduced plants appear in this zone. Many local pollen types were found, on account of local overrepresentation. This made it possible to compare the local Stevens Pond sequence with the composition of recent lowland vegetation types. The pollen sequence was similar to a large extent to the recent pattern of lake filling, starting with a eutrophic vegetation of Typha latifolia and Salix in the prairie period and leading to a Larix forest and then to a mesotrophic Picea mariana forest, the present edaphic climax on peaty soils. There is a delay, however, in the introduction of acidophilous species, the Larix forest being without Sphagnum and Ericaceae. This is explained by assuming an influence of the vegetation of the surrounding slopes upon the local vegetation. About 1900 the bog forest was destroyed by logging operations and replaced by the present Typha latifolia mat.

    Description: Some of the basic concepts common to plant taxonomy, palaeobotany and palynology are discussed such as “taxon”, “taxonomic categories”, “genus and species concepts”, as well as “organ and form genera”. The development of the specifically palaeobotanical and palynological concepts of organ and form genera is briefly treated in the light of the shaping of palaeobotanical thought and methods since Adolphe Brongniart. The need for a single category of an artificial nature (i.e., form genus) is acknowledged; the need for a second category of such nature (i.e., organ genus) is questioned. The general guide lines for good palynological practice given by Faegri et al. (1950) are recommended for future use and are reprinted as an appendix to this paper.

    Description: Three genera of the Proteaceae belonging to the tribe Grevilleeae occur in the Guianas and Brazil: Roupala, Panopsis, and Euplassa. The microscopical wood structure of one of these genera, Euplassa, has not been described before. Anatomically it proves to be nearly identical with Panopsis which it also resembles in general properties. Roupala differs in several respects. Within the genera differences are not fundamental and chiefly a matter of numbers and dimensions. A key to the genera is given.

    Description: *Burkill, I.H.: Chapters on the history of botany in India, 1965, xi + 245 pp., 4 portr., 2 maps. Manager of Publications, Government of India Press, Delhi 8. Sh. 12/6, or $ 1.98. It was not necessary to mention that Burkill began compiling this book at the age of 81 to finish it at 93, for, although the last two chapters are miscellaneous in contents, it could as well have been written by a man thirty years younger. Everybody will regret that the book ends at the time Burkill’s own contributions to Indian botany began, notably about 1900. As for the period covered, and that is from the earliest beginnings, the book is a rich store of information. It was published in chanters in the Journal of the Bombay Natural History Society 4 and has now, after considerable revision by the author, been brought out by the Botanical Survey of India, preceded by an Introduction by Father H. Santapau, the Director, who therein put Burkill’s considerable merits for Indian botany on record.

    Description: The affinity of the Malesian genus Lophopyxis has a checkered history, a survey of which was given by L.B. Holthuis & H.J. Lam, in Blumea 5 (1942) 205-208, fig. 7. It has been referred to Flacourtiaceae, Icacinaceae, Euphorbiaceae, Olacaceae, and Saxifragaceae. Hitherto no attention was paid to the similarity with Gouania in the Rhamnaceae, which it resembles in toothed leaves, presence of stipules, panicled spike-like inflorescences, and the occurrence of tendrils in these.

    Description: Taxonomists working with material collected by the Sarawak Forest Department have often been hard put to decide how to quote numbers. Is the departmental series number preceeded by a letter S, or an F, or would it be best to quote only the collector and the number? I have tried to unravel the history of the Sarawak Forest Department herbarium number series in order to provide a guide to unequivocal citation. This has not been easy, as all collecting books previous to 1951 have disappeared, apparently during the second world war; many of the herbarium collections are now missing at Kuching and Kepong, where most were distributed, for the same reasons, though there seem also to have been large gaps in the series where numbers were never used. What has eventually been brought to light has been a masterpiece of confusion only vied with in complexity by its Sarawakian forbear, the remarkable numbering, or rather lettering, system of Haviland (explained in Kew Bull. 1907, 197— 198).

    Description: These small structures in nerve axils at the underside of leaves have given food to various theories and have been nonetheless in phytographic and taxonomic neglect almost from the beginning. That was in 1887, when the Swede A.N. Lundstroem published an extensive paper, in which he explained domatia as structures intended to accommodate mites – hence the word acarodomatia – which latter would in turn benefit the plant by cleansing the leaves from fungus spores. Lundstroem arrived at this hypothesis on the strength of ideas current in that time, about the existence of symbiotic relations between ants and plants; it was in the heydays of teleology. A closer investigation left little of the illusions about mutual benefit between ants and plants, but such critical interest was never focused on the supposed relation between mites and plants. Recently I could grow a few domatia-bearing species under acari-free conditions; the plants with their domatia did as well as in the open. Yet it is hard to prove that Lundstroem was wrong, but a combination of the experiment, the wellknown fact that domatia are inhabited by acari as often as not, and the origin of the hypothesis make if very unlikely that mites will creep into domatia for other reasons than a natural preference for shelter in small holes. All other (physiological) explanations are unconvincing, too, and so for the time being an explanation is lacking – provided that such an explanation would be necessary.

    Description: Index to the Enumeration of the Orchidaceae of Sumatra, by J.J. Smith. At the Rijksherbarium there was a handwritten copy compiled by the late Dr. J.J. Smith of his important enumeration of Sumatran Orchids, published in Fedde, Repertorium 32 (1933) 130-386, which was obviously for reasons of economy not printed. The author left a note to the Librarian of the Rijksherbarium saying that it is indispensable for consulting this work, as many orchid names were here reduced to synonymy for the first time. This is now available for orchidologists and libraries in stencilled form in the same format as the Enumeration, with the Library of the Rijksherbarium, Schelpenkade 6, Leyden, Holland.

In several places the old substratum has been traced, and in the basal layer of the ash covers, which attain sometimes 30 m thickness, remains are found of former woody share vegetation. Bases of tree trunks have partly been buried in their upright position. Some of these are charred, and have apparently been burned during the eruption; others are not charred, or have been charred only very superficially.

    Description: In 1969 Indonesian botany suffered a severe loss by the untimely death of Dr. B. Prijanto, at the end of April. He was the head of the Forest Exploration Division, Forest Research Institute, Bogor. He belonged to that still very small, but admirable circle of young able Indonesian botanists built up in the early sixties, largely through the efforts of Dr. Kostermans. Dr. Prijanto studied palynology for one year at Stockholm, after which he proceeded to Edinburgh where he received a thorough training under Dr. Burtt, working largely on the systematics of Scrophulariaceae, in connection with problems in Gesneriaceae. He was a very nice and energetic man, full of plans for the future exploration of Indonesian forests. Our sympathy goes to his young wife, whom he had married only a few months before. He was a victim of an unfortunate car accident in SW. Celebes. The accident occurred when he was hunting for Eucalyptus with two Australian foresters, who both met an untimely death as well, one of them being Mr. E. Larsen, of Canberra. Another thing that lamed botanical activity at Bogor was the serious trouble which Dr. Kostermans ran into with the police by whom he was detained. We hope that he will soon be cleared and that this will be a mere incident which will not affect his energy nor his enthusiasm for Indonesian botany. Unfortunately, through this mishap, he was unable to lead the Seminars on botany in August, neither could he accompany the British Museum Botanical Expedition to Central Celebes led by Dr. Jermy. These tasks were taken over by Dr. Rifai. Dr. Kostermans was also unable to attend the opening of the partly finished new Herbarium building in October, towards the planning of which he had contributed so much.

Borneo Literature Bureau, Rock Road, Kuching, Sarawak (Printed by Cathay Press, Hong Kong). 1968. viii + 129 pp., 15 fig., 20 pl. (photogr.), large 8°, clothbound. M$ 18.00 + postage M$ 1.30; bank charges of M$ 1.75 are required on foreign cheques. This ’Supplement’ records all Dipterocarpaceae from Sarawak, to the huge number of 247, 12 of which are yet undescribed by being insufficiently known. In the large Brunei Manual, published by the Oxford University Press (1964), 153 of these species had already been fully described; besides in that book very full evidence was given in many other aspects. This information is not repeated here. The Supplement provides keys (one botanical and one field key in all cases) to genera and all 247 species quoting all Sarawak collections, and providing for a full botanical description of all species not recorded in the Brunei book. It is therefore to be used together with the latter. A great asset as a precursor to the Malesian dipterocarps. The work is excellently printed on good paper.—v.St.

    Description: The practice of citing collections made in institutional series by the letters of that series instead of by the collector’s name (e.g. FB 23435 instead of Aquilar & Valderrama FB 23435) led, with the publication of so many Identification Lists, to the dishing out of an alphabet soup that many a botanist or curator of collections may find hard to digest. In itself, the system of collecting in long institutional series is an excellent one, permitting great economy in space when collections are to be cited. The oldest series seems to be the KB-one, dating from about 1870, established by Scheffer, followed early in this century by the BS and FB series, established by Merrill. A good number-stamp may have contributed much to the success and consistency with which the series were maintained for a long time. In other institutes, there has been created what Dr. Ashton characterized as ”a masterpiece of confusion”, the unravelling of which, as can be seen from his paper on ”The numbering of Sarawak Forest Department collections” in this Bulleton on pp. 1432-1435 (1966), requires a good deal of research. The purpose of this paper is only to give a list of abbreviations in use between Thailand and the Solomons, for the guidance of those who compile, and those who use Identification lists. These Lists, products of the work for the Flora Malesiana, serve as documentation as well as being of use for the identification of Malesian duplicates not seen by a taxonomist himself. When compiling and using such a list, three questions are to be considered.

Indonesian timbers. A sample proof sheet was received of a book to be issued by the Indonesian Forest Research Station at Bogor. This will comprise a botanical treatment of about 400 of the most important timbers of Indonesia. Each species is to occupy 4 pages, viz a full page drawing, and one page for the text in 3 languages: Indonesian, Dutch, and English. Each description consists of the name and synonyms, preferent vernacular name, other vernacular names, geographical distribution, habitat circumscription, habit description, technical-botanical description, and notes. No mention is made of the anatomical characters of the wood; these will be published in a separate book which is prepared simultaneously. The book will probably be finished in 1956.

    Description: My visit to and trips in Taiwan, in 1966, brought me into close contact with the wonderfully rich and varied flora of this large island which is fairly easily accessible if one speaks Chinese or is accompanied by Chinese companions, as was my privilege. As is well known the woody flora of Taiwan is tolerably well known, by the excellent work of Kanehira (1936), followed by the modern works of Prof. Tang-shui Liu (2 vols, 1960-1962) and Prof. Li (1963).

    Description: Five species of Ganoderma Karsten are discussed, which are confined to the tropics and characterized by the presence of a light-colored context, but which are devoid of the laccate upper surface of the pileus typical of the species of the Ganoderma lucidum-group. Ganoderma neurosporum J. Furtado is proposed as a new species. Three of the five species—Ganoderma amazonense Weir, G. coffeatum (Berk.) J. Furtado, comb, nov., and G. neurosporum J. Furtado—are from the neotropics. Ganoderma lloydii Pat. & Flar. is known only from Africa, and G. asperulatum (Murrill) Bres. has been reported only from the Philippines and Borneo. Regardless of their geographical distribution, the five species under discussion are distinguished particularly by their basidiospore characteristics. In their morphological features they show several characteristics also found in some trocial species of Amauroderma Murrill.

    Description: Attention is drawn to the fact that the development of ascostromatic fungi is so diverse that it is possible to recognize a number of differently organized groups. Some of these groups correspond to the developmental types recognized by Luttrell but it is also shown that his Pleospora-type is not homogeneous, comprising as it does a number of categories, each of which has its own type of development of the ascocarp. To designate structures not indicated before, the new terms tichus, cataphysis, and tinophysis are introduced.

    Description: In Madroño (1936) Herre has lamented the disappearance of lichen species through the disastrous interference of man. Unavoidably, the advance of civilised modern life is linked with destruction of the vegetation. This applies all the more as the endangered area is more densely populated and it certainly applies most alarmingly to the lichen flora of the Netherlands. Here, every way-side tree felled is an irreparable loss to the epiphytic lichen communities, every acre of heath burnt or turned into arable land is a blow to our stock of terrestrial lichen species, whereas the use of dry fertilisers and the spraying of orchards are very effective in killing any lichen in the neighbourhood that otherwise might have survived. A comparison of the material preserved in the older collections with what can be found nowadays, clearly shows what has gone lost. It is sad to think that an ever increasing number of species are on their way to total extermination. However, from a thorough investigation of the epiphytic communities of cryptogams latterly started by Mr J. J. Barkman, it becomes apparent that at least to some extent the losses may be compensated by the discovery of species hitherto overlooked or not recognised. It is on such and other finds that I intend to report from time to time.

    Description: A revision of the species, comprised in the section Eu-Protium of the genus Protium from the region from Asia to Australia incl., might., in view of the elaborate publications by H. J. Lam (The Burseraceae of the Malay Archipelago and Peninsula etc., Bull. Jard. bot. Buitenzorg, S. 3, 12, 1932, p. 318—324) and J. J. Swart (A Monograph of the genus Protium and some allied genera, Rec. Trav. bot. néerl., 39, 1942, p. 211—146), seem superfluous. However, an examination of the Clemens material from New-Guinea of 1939 and of the type material of the thusfar mysterious Bursera tonkinensis Guill. justified the publication of some notes thereon. To these some remarks concerning observations on other species have been added. I am much indebted to the directors of the following herbaria for the loan of material: the herbarium of the Botanisches Museum, Berlin; the herbarium of the Arnold Arboretum, Jamaica Plain, Mass. (A); the herbarium of the Royal Botanic Gardens, Kew; the herbarium of the Museum d’Histoire Naturelle, Paris; the herbarium of the Botanical Institute, Wroclaw (BRSL); the “Rijksherbarium”, Leiden (L).

    Description: 1. A simple technique for acetolysis of small quantities of polliniferous (herbarium) material is described and notes on pollen photomicrography are presented. 2. Pollen grains of Sarawakodendron and six related genera, consisting of twenty-nine mostly Malesian species, have been examined and recorded. 3. The result of pollen study on Kokoona and Lophopetalum agrees with the generic delimitation based on gross morphology. 4. At least four pollen types have been found in the genus Lophopetalum on examination of all the species involved. 5. The pollen of Sarawakodendron shows a great resemblance to that of the related genera Xylonymus and Kokoona. 6. The pollen of Hedraianthera and Brassiantha resembles that of Sarawakodendron, Kokoona, and Xylonymus in aperture configuration, but differs in sculpture and shows in this respect similarity to the pollen of the African Salacighia. 7. In Kokoona coarseness of reticulate sculpture appears correlated with anther characters. This genus can also be easily distinguished from Lophopetalum by its single pollen grains. 8. Parallels are found between the pollen types in Lophopetalum and those in Hippocratea (sens. str.).

    Ruthiella, a new generic name for Phyllocharis Diels, 1917, non Fée, 1824 (Campanulaceae) (1966)

    Description: In Taxon 10 (1961) 261, a proposal was published to conserve the generic name of the Papuan genus Phyllocharis Diels, 1917, against Phyllocharis Fée, Essai Crypt. (1824) lix, xciv, t. ii, fig. 3 & 7, a name for a genus of Lichens. Fée was the only author who ever recognized it; it was reduced by Montagne about 15 years later and this reduction was accepted by all later lichenologists. As a matter of fact an experienced lichenologist was one of the three botanists who endorsed the proposal by undersigning it. Therefore, no harm would have come from accepting the proposal and this would have been distinctly useful for stabilizing the generic name Phyllocharis in the Campanulaceae, not only for the few botanists working in New Guinea, but for all handbooks and monographs on the family. It is precisely for this purpose that there is the provision in the Rules to conserve generic names. No useful purpose is pursued to drop established names if it is reasonable to maintain them, which I strongly think it is in this case. The proposal has unfortunately been found redundant by the majority of the Subcommittee for Phanerogams (Taxon 12, 1963, 238) and was rejected. This necessitates the creation of a new generic name and the transfer of the epithets. Ruthiella Steen. nom. nov. — Phyllocharis Diels, Bot. Jahrb. 55 (1917) 122, non Fée, 1824; Wimmer, Pfl. Reich Heft 107 (1953) 724; Tuyn, Fl. Mai. I, 5 (1960) 137.

    Description: Argostemma Wall. (type species: A. verticillatum Wall.). This large Old World genus, comprising about 240 binomials of which, ca 70-80 will prove to be distinct species, has been almost unanimously left undivided. Exceptions are Reinwardt who in 1825 created the genus Pomangium, independently of Wallich (1824) and Ridley who in 1927 based the genus Argostemmella on two Bornean species of Argostemma. My revision (in msc.) of Argostemma occurring in Malaysia confirmed the common view that there is no reason for splitting up this genus. However, several subdivisions (sections) can reasonably be accepted. As those sections mostly represent well-delimited taxa in connection with a rather evident distribution of their own, I propose here the following 5 sections for Argostemma. It should be borne in mind that I have examined almost all extra-Mallaysian species too.

    Description: This is the second book by professor Meeuse on the phylogenetic morphology of the reproductive organs of the Higher Cormophytes. It is superior to the first *, not only in the get-up, but also in providing some more information on the principles of the author. The core is disclosed in: ‘all we can do is to postulate a phylogenetic genealogy, using all available (palaeobotanical) evidence, and build up the evolutionary sequences in the phylogeny of the organs, the semophyleses, along our framework’. And: ‘Typology is to be checked by fossil data’. We meet the method of the New Morphology, as it was started by H. Hamshaw Thomas. The phylogenetic line depicted leads from the Progymnospermopsida Beck through Cycadopsid Gymnosperms towards Angiosperms. It is impossible to distinguish Angiosperms from Gymnosperms. They are specialised Cycadopsid Gymnosperms, exhibiting polyrheitric angiospermic trends, such as angi-ovuly, double fertilisation, dormant embryo phase, flower types, wood vessels, and aperturate pollen. Some groups have not reached the ultimate level in part of these characters.

    A revision of the genus Cratoxylum Bl. (Guttiferae) (1967)
    In:  Blumea - Biodiversity, Evolution and Biogeography of Plants (0006-5196) vol.15 (1967) nr.2 p.453

    Description: A complete revision is given of the Indo-Malesian genus Cratoxylum. The subdivision of the genus into 3 sections, as given by Engler (1925) and Corner (1939), has been found correct. The characters by which these sections are discriminated concern the interpetiolar scars on the twig, the type of venation, the occurrence of petal-scales and their shape and size, the shape of the hypogynous scales alternating with the three staminal phalanges, and whether the seeds are surrounded by a wing or are winged on one side only. Each section contains two species. A concise review has been given about the history of the genus, an account of the uses made of it, and the ecology. It appears that almost all species can act as pioneers for which they are fully qualified by their euredaphic requirements and early and abundant seed production. Though some species, notably C. arborescens and C. glaucum, are evergreen, and C. formosum is deciduous, the others are not specifically one or the other way round; in C. maingayi Corner noted that sometimes particular branches shed their leaf. There is no major correlation between leaf-shedding species and seasonal climate regime. A brief summary is given on the morphology, in particular the structure of the inflorescence. Two points have not become entirely clarified, for example, whether all species are always heterodistylous: this should be studied further in the field. Another point is the want of more exact data on the degree in which the ovary is incompletely celled which seems to differ from one species to another, and to compare this with the ovary of the allied Madagascan genus Eliaea (vide infra). C. glaucum excepted all species show a distinct variability. In three species this is grading and no infraspecific taxa can be distinguished in a key on the basis of herbarium material. Within Malesia the variability is more or less of a geographical character and could be classified under clinal variation. This is also the case in C. sumatranum and C. formosum, within which I can distinguish, however, three and two infraspecific taxa respectively, which accordingly have been given racial rank, that is, as subspecies. Within each a still finer distinction might be feasible of subsubraces which mostly coincide with separate islands of Malesia. The closest related genus is the monospecific genus Eliaea Camb. from Madagascar with which it forms a tribe of the Guttiferae. With regard to the exact structure of the ovary claimed to be distinct from that of Cratoxylum a close comparative-morphological study should be made of the ontogeny of the ovary in Eliaea and all species of Cratoxylum. Except from taxa described by Loureiro, Jack, and Blanco, of whose names no types seem to exist, I have for the first time examined type material of all names and checked their detail floral characters which were often not mentioned in the original diagnoses. A listed account of all numbered material on which this study was based will be published in a separate ‘Identification List’.

    The genus Lophopyxis Hook. f. (Lophopyxidaceae) (1968)

    Description: When revising the Icacinaceae from SE. Asia and Malesia recently, my interest was drawn again to the genus Lophopyxis Hook. f. Designated by its author (1887) tentatively as a member of the Euphorbiaceae, it was rejected from this family by Pax as early as 1890. Engler (1893) transferred Lophopyxis to the Icacinaceae as the type of a new subfamily Lophopyxidoideae. Hallier f. (1910) disputed Engler’s view and retained it in the Euphorbiaceae, from which it was excluded again by Pax & Hoffmann in 1931. A possible place in the Rhamnaceae and Flacourtiaceae was considered and rejected by Gilg in 1918; Bakhuizen van den Brink Jr. & van Steenis (1966) likewise rejected the former, though its alliance with the Rhamnaceae was firmly expressed by Airy Shaw (1966). Other authors, as Pierre quoted by Boerlage (1890), inserted Lophopyxis in the Saxifragaceae, Schumann (1898) in the Olacaceae, and Ridley (1922) in Bentham’s Olacineae. In more recent times the genus was referred again to the Icacinaceae by Schellenberg (1923) and Kanehira (1931), but excluded from that family by Hallier f. (1921) and Sleumer (1942). Dahl (1955), discussing the pollen morphology of Lophopyxis, stated that the range of pollen forms known to exist within the Euphorbiaceae could include that of Lophopyxis. Erdtman in the newest edition of his ‘Pollen Morphology and Plant Taxonomy’ (1966) still placed it under Euphorbiaceae. Hutchinson (1959), and subsequently Scholz (1964), place it in the Celastraceae. Though Lophopyxis fits in the general circumscription of the Celastraceae, and shares the winged fruit with the subfamily Tripterygioideae, it cannot be placed in the latter, which all have basal ovules, whilst Lophopyxis has pendent (and certainly epitropous) ones. If placed in the Celastraceae, it would keep an isolated position, as, for instance, does Siphonodon. There is thus no certainty as to the right place of this genus, whose gross morphology, wood anatomy, embryology, and pollen morphology is so well known to-day, in one of the established plant families. It therefore seems justified to regard it as the type of a family of its own within the Geraniales-Sapindales-Celastrales. Suggested already by van Tieghem (1897) and Pierre (1897) casually as Lophopyxidacées’, the family was formally described by Pfeiffer (1951) who raised Engler’s Lophopyxidoideae to family rank, and recently conceived by Airy Shaw (1966).

    Description: The populations of the seaward intertidal ends of the 1955 lava flows in Hawaii were studied during the first few years of their development. Different seral phenomena were recognized such as pioneer colonization, succession, disclimax, and subclimax. The term climax is used as a practical term to denote existence of an equilibrium between the populations and the environment. Appearance of the climax situation seems to be related to stability of the substratum for a period at least as long as six to ten years, but even populations on surfaces as old as 100 years are different from some that are on adjacent prehistoric surfaces.

A discussion of the rationale is presented, 38 characters are studied for advanced versus primitive states, advancement indices calculated, and trends of variation discussed. The six major groups of Phipps (1966b) are maintained. The phylogeny conforms excellently with the geographical aspects of the continental drift hypothesis though it requires a greater age for the Angiosperms than is generally held to be the case.

    Description: The previous subdivision of Freycinetia Gaud. ( Pandanaceae) into two parts, Sect. Oligostigma Warb. and Sect. Pleiostigma Warb. (now called Sect. Freycinetia) has because of numerous additions to our knowledge of the genus become obsolete. Fifteen new sections are proposed, based on natural species-groups, and the original two sections are restricted and redefined. Species not yet adequately known may be termed Freycinetiae imperfectae, when only staminate specimens are known, or incertae sedis. A map showing the distribution of the genus is included.

    Description: Trees; leaves with caducous stipules; tertiary nervation descendant, but usually lax and irregular; inflorescences clustered, axillary, manyflorous; calyx with two rows of four lobes each; corolla 8-merous, each lobe with 2 dorsal segments as long as itself; stamens epipetalous, 8, in the same row as the 8 alternipetalous staminodes; ovary usually 8-celled; cells 1-ovuled, ovules anatropous, attached at the base; fruit a berry, 1—2-seeded; seeds with a small, circular, basal scar, in which the hilum and the micropyle are placed close to one another; albumen abundant; cotyledons thin, foliaceous; radicle long, cylindrical, exsert — About 80 species in all tropical countries, except in America. In 1925, Lam (Bull. Jard. Bot. Bzg, sér. 3, 7, 1925, 235—237) described of M. elengi three varieties, var. typica, var. parvifolia and var. brevifolia and a forma longepedunculata in the type-variety. As was pointed out already by him, the differences between the two new varieties are slight, if existing at all. As those between M. elengi and M. parvifolia were obscured by many intermediate stages Lam was forced to consider the latter a variety of the former. Studying the more abundant material at our disposal it becomes clear that M. elengi is an extremely variable species in which it is impossible to distinguish varieties or forms. However, it must be pointed out that in the western parts of the Archipelago the leaves are large (up to 18 cm long), whereas they are decreasing in size towards the east, ending in the small leaves of the former species M. parvifolia (up to 6 cm long).
