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.

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.

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: 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: In my first paper (1951) a part of the tribe Eupodostemeae was revised, viz. the genera Apinagia, Marathrum, Rhyncholacis, Lophogyne, Monostylis, Jenmaniella, Wettsteiniola and Macarenia. The second part deals with the subfamily Tristichoideae, which comprises the genera Tristicha and Weddellina, and the tribe Mourereae of the subfamily Podostemoideae, which consists of the genera Mourera, Lonchostephus, and Tulasneantha.

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: Dr J. Hutchinson retired after 44 years of service in the Royal Botanic Gardens at Kew (May 31, 1948), as Keeper of the Museum. He will devote his time mainly to the writing of some general handbooks especially his Genera Plantarum. He was succeeded by F.N. Howes, D. Sc. Mr H.K. Airy Shaw was appointed Principal Scientific Officer, Royal Botanic Gardens, Kew, on Dec. 31st, 1948.

Description: A growing interest in the Flora Malesiana was a chief characteristic of 1950. The number of free subscriptions increased to over 320 and the total of subscriptions, therefore, to over 620 as the Government of Indonesia receives 300 copies for official purposes. The first volume of series I, the Cyclopaedia of Botanical Exploration in Malaysia, which contains the main bibliographical and biographical data of all collectors in Malaysia, accompanied when advisable by an itinerary and information concerning the collections, has now been printed. It is expected that the volume will appear before the end of the year thus bringing Mrs.M.J. van Steenis-Kruseman’s patient and devoted work during more than 12 years to a conclusion.

Description: Centenary of the Kew Herbarium and Library. If we are well informed the centenary of the Herbarium” and Library of the famous Royal Botanic Gardens, Kew, occurs in 1953 and will be informally celebrated by an Exhibition in the Herbarium on the 8th and 9th of May, 1953, which will, we assume, be attended by many of the countless friends of this Mekka of Botany and in honour of the unsurpassed service which it renders to botanists all over the world. 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: Dr R.C. Bakhuizen van den Brink Jr, Leyden, made a provisional revision of the genus Ophiorrhiza (Rubiaceae). Onwards of 1953 he will be working on the completion of Backer’s Flora of Java. Dr M.J. Baumann-Bodenheim who made a big collection of plants in New Caledonia during the past two years has been temporarily appointed at the Bot. Garden Zürich for the working out of this collection.

Description: It is advised to address all mail with destination Royal Botanic Gardens, Buitenzorg, in future as ’Royal Botanic Gardens, Bogor (Buitenzorg)’ The present number, Flora Malesiana Bulletin No. 6, concluded the 1st volume. The second volume of the Flora Malesiana Bulletin begins with no. 7.

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: The vegetative characters — especially those which are important for identification of the species — together with the distribution of the Polysiphonia species occurring in Netherland’s waters were subject of the following study. The material used consisted for the greater part of dried specimens, present in the following collections: Rijksherbarium (Leiden), herbarium Van Goor, Zoological Station (Den Helder), herbarium of the “Koninklijke Nederlandse. Botanische Vereniging” (Rijksherbarium, Leiden) and the herbaria of the Universities of Amsterdam, Groningen and Utrecht.

Description: This paper on the Philippine species of Argyreia forms an addition to that published by the same author in Blumea V, 2, (1943) p. 352—383. As to the description of the genus, the limitation of it against Rivea and the inclusion in it of Lettsomia may be referred to what has been said on p. 353—356 of that publication.

Description: In the course of my study on the wood-anatomy of Javan woods (Mikrographie des Holzes der auf Java vorkommenden Baumarten), I examined also many woods from mangrove-trees. Mangrove has been the subject of much investigation; the community is usually described as xeromorphic. Mangrove woods proved to be different from woods belonging to species growing in other stations even if those species belonged to the same family or even genus. The data may be traced in my “Mikrographie” but it seems more convenient to review them here.

Description: Faisant suite aux levés géologiques dans la zone Nord-Pyrénéenne et dans la zone axiale des Pyrénées ariégeoises et de la haute-Garonne, le Val d'Aran et le Haut-Pallaresa ont été incorporés dans la cartographie depuis 1952. Néanmoins les résultats provisoires ont déjà une importante influence sur notre conception de la structure générale de la zone axiale centrale. Il paraît utile d'en esquisser une première ébauche, quoiqu'il paraîsse certain que beaucoup de détails seront corrigés par les levés postérieurs. Le Val d'Aran depuis el Puente del Rey jusqu'au Puerto de Bonaigua constitue un vaste bassin dans lequel naît la Garona, alimentée par une dizaine d'affluents venant du Sud, de l'Est et du Nord. Sa situation au centre de la grande chaîne paléozoique des Pyrénées en fait le lieu le plus propice pour étudier le développement stratigraphique du Primaire et sa déformation structurale accompagnée de deux phases magmatiques, datant de la fin de cette époque.

Description: The numbers (St. ...) quoted in the present systematic part, are the registration numbers of specimens in the Geological Museum at Leiden. The molluscan collection from Poeloe Boenjoe comprises the numbers St. 41757—’61 (inclusive), ’63—’70, ’73—’97, ’99—41802, ’04—’09; Tarakan: St. 41742—’50, ’98. Other organisms: Boenjoe: St. 41762, ’71, ’72, ’95, 41803; Tarakan: St. 41751, ’52, ’53, ’54, ’55.

Description: Depuis longtemps on trouve dans la littérature sur la géologie des Pyrénées des discussions sur les lherzolites et les ophites, concernant leur origine, leur âge et leur mode de formation. En général ces discussions ont rendu difficile l'éclaircissement de ce problème et un résumé de toute la littérature manque jusqu'ici. Dans un rapport inédit de l'Institut géologique de l'Université de Leyde M. H. Heetveld a rassemblé toutes les données sur les lherzolites et ophites, et en vérité il est difficile d'en tirer une conclusion. C'est pourquoi nous ferons dans cet article une proposition quant à leur définition et leur âge et mode de formation. Les deux termes lherzolite et ophite sont bien définis: la lherzolite est une roche consistant essentiellement en olivine ,parfois serpentinisée, et en plus de diallage ou diopside, bronzite et picotite. En réalité une lherzolite est une péridotite avec un caractère spécial. L'ophite est une roche composée de plagioclase, An 40—70, pyroxène, souvent ouralitisé, et quelques minéraux accessoires, avec une texture ophitique.

Description: Depuis 1948 des groupes d'étudiants en géologie de l'Université de Leiden sous ma direction, plus tard assisté par M. Zwakt, se sont occupés de la géologie du Primaire des Pyrénées centrales. Le levé s'est déplacé graduellement du Nord vers le Sud et de l'Est vers l'Ouest, de sorte qu'en 1953 nous avons dépassé la frontière franco-espagnole et entrepris la cartographie du Val d'Aran et de la Haute Pallaresa. Evidemment nous nous sommes basés largement sur les travaux de nos prédécesseurs, français surtout, et sur les feuilles au 80.000ième de la carte géologique, dont surtout les nouvelles éditions des feuilles de Foix et de Bagnères de Luchon ont été un precieux appui. Tous les noms des grands géologues pyrénéens, de Leymerie, Caralp, Mussy, Dalloni, Léon Bertrand, Raguin, Casteras, sont associés à ces cartes et je crois qu'il est superflu de rappeler à chaque instant leur rôle individuel dans ce court exposé. Le manque presque total de fossiles oblige chaque géologue de terrain de notre région à opérer par comparaisons de facies lointains et considérations générales et l'oblige à cartographier la totalité d'une grande région afin d'aboutir à une conception générale. Chaque lacune du levé de terrain se venge irrévocablement par des raccordements faux, il faut tout suivre sur le terrain, autrement on tombe dans des erreurs graves puisque les facies ne sont pas très constants.

Description: In the collections of the Leyden Geological Museum is a set of fossiliferous clay-stones which was long ago collected by the mining engineer Hulshoff-Pol in the coal quarries of Batoe Panggal 1), Eastern Borneo. He presented the collection in 1902 to Dr M. Schmidt, who at that time was making geological investigations in Borneo. After Dr Schmidt’s appointment to a professorship in Stuttgart, the fossil collections made by him in Borneo were acquired by the Leyden Geological Museum (1920). Fig. 1 roughly indicates the locality of Batoe Panggal, while Fig. 2 depicts the delta area of the Mahakkam or Koetei river and its neighbouring areas. The dotted area is again represented in Fig. 3 below.

Description: Un des plus grands phénomènes structuraux des Pyrénées est sans doute la faille Nord-Pyrénéenne qui longe la zone axiale depuis la Méditerranée jusqu'à la côte atlantique. Elle est caractérisée par plusieurs particularités exceptionelles, dont le métamorphisme des terrains jurassiques et crétacés inf., accompagné d'intrusions de roches basiques est le plus important.

Description: 1. This paper deals with a pollenanalytical investigation of holocenic peat-layers in Central Friesland. 2. One diagram shows a praeboreal spectrum with Betula in the dominant position, the first appearance of thermophilous trees (Corylus, Alnus) and a high percentage of Gramineous and Cyperaceous pollen. 3. Originally in all diagrams the percentages of Ericaceous pollen are low. 4. During the boreal time the peat formation was of little importance. A maximum of Corylus pollen in the boreal period has not been found here. 5. In the Atlanticum a thick layer of peat has been formed; the percentage of Alnus pollen remains high, the Quercetum-mixtum fluctuates between 10 and 25 per cent and there is also much Corylus pollen. 6. Two narrow clay-bands are present in the peat. They contain many pollen grains of halophytic plants, which indicates that there must have been two marine transgressions in the Atlanticum. These transgressions will have reached their farthest point in this region. 7. In the upper atlantic and subboreal peat-layers there are many fragments of Ericaceae and also a high percentage of Ericaceous pollen. 8. The Young Sphagnum peat consists of Sphagnum species of the Cymbifolia section. The presence of Fagus pollen never reaches a level of 10 per cent. 9. During the subatlantic transgression the Young Sphagnum peat has locally been washed away and was replaced by clay with many Phragmites rests. The author wishes to express his thanks to “It Fryske Gea”, the Frisian association for the protection of nature, president Mr. M. WIEGERSMA, Drachten, for the permission to take samples at “Het Princehof” and for the assistance to this work. He is also highly indebted to Dr. F. P. JONKER for his assistance and interest during the investigation and to Prof. Dr. C. E. B. BREMEKAMP for correcting the English text.

Description: The list of Araceae published in 1906 by A. A. PULLE in his “Enumeration of the Vascular Plants known from Surinam” comprises 39 species belonging to 14 genera, the largest genera being Anthurium with 7 species and Philodendron with 12 species. It was found that one of these 39 species was included by mistake, for the specimen Wullschlaegel n. 1764, which is the type of Spathiphyllum blandum Schott, was erroneously assumed to have been collected in Suriname. Already in 1908 TRESLING had collected a species that was not listed by PULLE, viz. Dieffenbachia picta (Lodd.) Schott.

Description: Blume, C. L, Bijdragen tot de kennis van de Flora van Nederlandsch Indië. Reprint of part 4 ( 1850). Dr M. A. DONK draws attention to the fact that part 4 of BLUME’ s Bijdragen was reprinted in 1850, at Batavia. The printers were VAN LANGE & Co, not the Landsdrukkerij this time. A copy of this second edition is in the Bibliotheca at Bogor. The letterprint is different from that of the original and the paper is of inferior quality. The numbering of the pages is kept as much as possible in agreement with the original edition. At Bogor there is an other copy of the Bijdragen in which part 4 is in MS,; this indicates that at some time no stock was available of the original edition.

Description: Mr A.G.L. Adelbert was on short leave in Holland, Nov. 1951-April 1952; during Dr Donk’s leave he has been appointed acting Keeper of the Herbarium Bogoriense. Mr E.G. Browne assumed duty as Head of the Sarawak Forest Department, Jan. 1951.

Description: In the following the abbreviation B.Z. means ’Binnenlandsche Zaken’ or ’Ministry for the Interior’; all records referred to are preserved in the National Archives (’Rijksarchief’) at The Hague. By Royal Decree of Febr. 10, 1839, no. 101 (cf. B.Z., 5th Div., Febr. 18th, 1839, no 132) it was decided to publish a printed work at the expense of the Government. The issue was to consist of 250 copies and each of the planned 3 volumes were to contain c. 400 pp., 60 (coloured) plates and quarterly instalments were to be published. The costs were to be deducted from the funds granted to the ’Natuurkundige Commissie’ (Board for the Naturel Sciences) who had explored in the Dutch East Indies since the withdrawal of the English (1816). The work should embody the scientific results of the ’Commissie.’

Description: The death of Cyril Tenison White, Government Botanist, Brisbane, Queensland, occurred on August 16, 1950.; The news came suddenly and hit hard; we lost one of the kindest and gentlest of men and, besides, the greatest living authority on the Papuan and Melanesian flora. Mr White had been seriously ill, two years ago, but seemed to have recovered. His heart remained weak, however, and though he seemed in good health, he had to desist from mountain climbing.

Description: Koorders, Fl. v. Tjibodas 2 (1923) 32—46; Hochreutiner in Candollea 2 (1924—1926) 336—359; Ochse, Indische Groenten (1931) 719—722; Backer, Onkruidfl. Java Suiker (1930) 203—209; Aimshoff in Blumea 5 (1942—1945) 515—517. Miss Dr G. J. Amshoff started the revision of the Javanese Urticaceae, but left the definitive preparation to me. Urtica dioica L. and U. urens L. have been erroneously recorded for Java (Miquel, Fl. Ind. bat. 1², 1859, 227; Koorders, Exk. Fl. Java 2, 1912, 126). To my knowledge no specimens were ever collected there nor elsewhere in the Malay Archipelago.

Description: Little attention has been paid till now to the algae, transported to the Netherlands coast on drifting objects. About a century ago T. D. Vrijdag Zijnen and G. Bisschop (near Scheveningen, ± 1845), and L. H. Buse (between Wijk aan Zee and Zandvoort, ± 1840—1847) were the first to pay attention to this subject. The material collected, especially that by the first two investigators, is mentioned in the Prodromus Fl. Bat. (1853). The book of Van Goor (1923) contains a chapter on these algae, in which, however, only few new observations occur. The author is much indebted to Dr Josephine Th. Koster for her kind help, as well as to Dr S. J. v. Ooststroom. The material, collected by Vrijdag Zijnen, Bisschop and Buse is almost completely present in the collections of the ‘Rijksherbarium’ and the ‘Koninklijke Ncderlandse Botanische Vereniging’, Leiden. The material, collected during the last few years has for the greater part been brought together by the present author, and furthermore especially by K. Swennen (Den Helder), J. Stock (Amsterdam), A. Mulder (Haarlem) and P. Leenhouts (Scheveningen). This material belongs to the collection of the Rijksherbarium, Leiden, but most of it is, for the time being, put under the charge of the “Comité ter Bestudering van de Nederlandse Mariene Flora en Fauna” (“Committee on the Netherlands’ Marine Flora and Fauna”) and temporarily preserved in “Het Filiaal”, Leiden.

Description: During the long years I was engaged in writing my “Mikrographie” (1), my main purpose was to give a survey of the wood-anatomy of as many representatives of the javanesc wood flora as I could lay hands on, in connection with Koorders’ and Valeton’s “Bijdragen” (2). My attention being almost exclusively absorbed by the descriptive side of my task, little attention was paid to eventual conclusions regarding family relationships, though some were incidentally pointed out. When this work of long years was completed, the need of a key for the identification of wood samples was felt. This I composed and completed just before the war. It was published in 1940 and written in German (3), as was the main work on which it was based. Immediately an English translation was prepared but though this was ready for the press as early as 1942, I was prevented from publishing it, at first because of the German occupation and later on for want of funds.

Description: Teucrium vesicarium Mill.; Epling, Syn. S. Amer. Lab. in Fedde, Repert., Beih. 85 (1935—1937) 3. Hab.: im Wald um Santa Cruz, 450 m alt., Jan. 1911, n. 1334.

Description: Tn the Malaysian area proper this small genus is represented by one species only (G. floribunda), but it seemed preferable to extend this work to a revision of the whole genus. The species of this genus are not easily distinguishable when sterile and the identification of such specimens is all too often made on geographical evidence.

Description: It is a pleasant duty to announce a work to which all students of the Malaysian Flora, and I am sure, many others, have been looking forward for some time; the first issue of, it is hoped, a very long and continuous series which will ultimately lead to a complete flora of the Malaysian region, including British Malaya, the Philippines and New Guinea which, floristically speaking, forms a natural unit. The work, written in English under the auspices of the Royal Botanic Garden, Buitenzorg (now Bogor), Java, is the result of the painstaking efforts of its Editor-in-Chief, the well-known Buitenzorg botanist, Dr C. G. G. J. van Steenis. Generously supported by his wife in many respects, he has, and under the most difficult circumstances, indefatigably fought to get this extensive project started. Not ony he, but the Indonesian Government as well, are to be congratulated on the result of their efforts. It deserves our sincere and warm appreciation that the Government of this young country has understood its responsibilities and is backing the work with considerable interest, both morally and financially.

Description: A recent collecting trip extended the region to which these Studies originally referred in such a way that it seemed wise to change the original title, so that not only the arid area off the North coast of South America was indicated as the field of study. Although as yet these Studies are principally based on material collected by the editor on his three trips to the Caribbean, this volume proves that results obtained from material of different origin will be incorporated.

Description: Dr P. Wagenaar Hummelinck entrusted me with the identification of the mosquitoes he collected during his trips to the West Indies in 1936—1937 and 1948—1949. Although dr Hummelinck told me that it was not his intention to catch representative material, the present collection is of particular hygienic and biological interest as some mosquitoes were found on islands from which they had not been reported before. This paper deals with 16 species: Wyeomyia celaenocephala — Curaçao, Anopheles pseudopunctipennis pseudopunctipennis — Margarita, Curaçao, Aruba, Anopheles albimanus — St. Martin, Aëdes taeniorhynchus — Curaçao, Saba, Dog Island, Aëdes aegypti — Curaçao, Aruba, St. Barthélemy, St. Martin, Haemagogus anastasionis — Curaçao, Aruba, Psorophora confinnis — Bonaire, Curaçao, Psorophora pygmaea — St. Martin, Deinocerites cancer — St. Martin, Culex erraticus — Curaçao, Culex americanus — St. Eustatius, St. Martin, Culex bahamensis — St. Eustatius, St. Barthélemy, St. Martin, Culex maracayensis — Curaçao, Culex chrysonotum — Suriname at Zanderij, Culex coronator — Venezuela near La Guaira, Culex nigripalpus — Bahamas, on South Bimini, and Culex quinquefasciatus — Bonaire, Curaçao, Aruba, St. Eustatius, St. Martin.

Description: Among the material brought together in the West Indies by Dr P. Wagenaar Hummelinck there are some coral colonies of the genus Tubastraea that are interesting from various points of view, in the first place because this genus of Madreporaria has but recently become known to occur in the West Indies. Vaughan & Wells (1943, p. 239) note as range of distribution of the genus Panamá, Indo-Pacific, Gulf of Guinea, and the West Indies. As I did not succeed in finding data in the previous literature on the occurrence of Tubastraea in the West Indian area, I wrote to Dr J. W. Wells, Cornell University, Ithaca, New York, who kindly informed me that the statement given above was based on otherwise unpublished recent finds of material from off Puerto Rico, whilst later a specimen was received from Curaçao. Moreover, the genus is mentioned in the Taxonomic Key to Genera of Living Western Atlantic Corals in Smith (1948, p. 108). Vaughan & Wells (l. c., pp. 238/239) define the genus Tubastraea with the following characters: “Like Endopsammia, but producing small subplocoid clumps by extratentacular budding from the edge-zone, polyps remaining organically united and with corallites united by some coenenchyme and feeble costae. Columella feeble, but occasionally well developed.” As the authors refer to the genus Endopsammia, the characters of the latter genus also may be cited here (l. c., p. 238): “Simple, subcylindrical, nonepithecate, fixed by broad base. Wall thin, costate. Septa thin, arranged according to Pourtalès plan only in early stages, later appearing normal. Columella small and spongy or scarcely developed.”

Description: The present paper deals with a small collection of Neogene fossils which has been made by the geologist Dr. M. Schmidt in the Sangkoelirang area 1), East Borneo. The locality is defined in Gerth’s (1923) and Krijnen’s papers (1931, loc. no. 175, p. 535). It must be stated here that this locality has been mentioned incorrectly in literature, viz., as “Hill near Sekoerau” instead of “Coral limestone, Hill near Sekoerau”. Dr. Schmidt’s collection, which was sold to the Leyden Geological Museum in 1920 — about twenty years after being made — contains two different faunas from Sekoerau: vide infra.

Description: While studying the parasitic copepods of the Dutch Waddensea, at the Zoological Station Den Helder, I came across a species of Bomolochus from the gills of the Black Sole, Solea solea (L.). Except for the second leg, the various appendages resembled those of B. soleae CLAUS, as figured by TH. & A. SCOTT in their Ray Society Monograph (1912—13). According to them, the endopod of the second leg has narrow joints, like the exopod. They stated that the second and third leg have about the same structure. In my material, however, the endopod of the second leg has widened joints; second and third legs have, therefore, quite a different aspect. Of TH. and A. SCOTT’S material, 2 samples remained**) in the collections of the British Museum (Natural History), Londen. The specimens proved to be quite distinct from the Dutch ones, differing not only in the structure of the second leg, but also in several other, less striking, characters.

Description: De moeilijkheden, die optreden bij het determineren van de Nederlandse vertegenwoordigers van het genus Centaunum (= Erythraea), waren voor mij aanleiding het Nederlandse materiaal eens aan een revisie te onderwerpen. De Franse flora’s b.v. vermelden een aantal soorten, waarvan het voorkomen in Nederland niet onmogelijk is (lit. 1, 2, 9). De bewerkingen van het Britse materiaal door WHELDON and SALMON in 1925 (lit. 15) en door GILMOUR in 1937 (lit. 4) wezen uit, dat ook in Engeland tal van soorten en variëteiten voorkomen, die voor Nederland onbekend zijn. Tenslotte verscheen in 1940 een bewerking van het Scandinavische materiaal van C. vulgare door STERNER (lit. 12), waarbij eveneens tal van vormen voor de dag kwamen en ook een voor Nederland onbekende soort. De Zweed WITTROCK heeft zich het meest intensief met het genus bezig gehouden. Hij gaf een aantal exsiccaten uit onder de naam „Erythraeae exsiccatae” en was van plan een monografie van het genus te publiceren. Dit laatste is door zijn dood in 1914 verhinderd, zodat we van zijn resultaten niets anders weten dan het gepubliceerde in enkele referaten (lit. 16) en de niet geldig gepubliceerde manuscriptnamen van de exsiccatae. WITTROCK’s exsiccaten zijn in de Nederlandse herbaria niet aanwezig.

Description: The genus Qualea is found in tropical South America, particularly in the Hylaea and in the Extra Amazonian part of the Brazilian mainland (see fig. 3); it comprises 59 species as defined in this paper. Many species are forest trees occurring in the Amazonian basin, a number are found in the Brazilian Atlantic coastal forests, whereas other species are typical trees of the campos of the interior plateau. The genus was first described by AUBLET in 1775; its name is a latinization of the vernacular name “Qualé” used by the “Caribbean” inhabitants of French Guiana. AUBLET described O. rosea (type species) and Q. coerulea; the first exhaustive and morphologically correct description was given by A. DE ST. HILAIRE (1820) who placed the genus in his newly established family of the Vochysiaceae.

Description: On request of the Army, several voluminous bibliographies nave been published in Japan during the war. Advanced scientists accomplished the work in collaboration with teams of students by using Japanese libraries. The first of these bibliographies appeared in 1942, the last in 1944. They were apparently already planned before the war and intended to form one of the sources of information for the Intelligence Service. They were published under the general title ’Bibliographic Index for the study of the natural resources of the Great Asia co-prosperity sphere’ and compiled by the Department of Education, Dai Nippon.

Description: The second instalment of the Flora Malesiana was published in December 1949. It contains pp. xli – clxi ana 41-140, and c. 160 illustrations. The total issue is fixed at 1000 copies of each instalment. At the present moment more than 550 subscriptions have been received. It seems that the future of Flora Malesiana is assured. The second instalment of volume 4 contains the final part of the ’General Considerations’, by the general editor, ’A short history of Malaysian phytography’, by Dr H.C.D. de Wit, and revisions of Malaysian, plant families by Dr C.A. Backer, Dr P. Buwalda. and by Dr C.G.G.J. van Steenis.

Description: This is, I believe, the most important single contribution in the field of Hymenomycetes for years. The author was attracted to the group commonly known as Clavariaceae as early as 1925 when in England; he continued his studies when working on the staff at the Singapore Botanic Gardens and after his return to England. He got the conviction that before science could undertake a wholesale revision of the present classification of Hymenomycetes, the larger constituent groups should be worked over, one at a time, and ‘their particular kind of fruit-body described in terms of hyphal properties’, and that to omit the tropical element would mean certain failure. Thus, the aims of this admirable volume become clear: a large number of species of “Clavariaceae“ are described in an exemplary manner as to their hyphal structure after the living state, and about all that is known about the group and its species was compiled so that the often quite inadequate tropical library has to a large extent become superfluous. This is one of the rare occasions on which we find that an author’s field knowledge of a group is based rather on tropical than on European or North American materials The author combines with an exceptional tropical field experience, the insight of an agile mind and a great artistic skill for drawing. It might be regretted that he neglected the many and scattered poor specimens in the European and American herbaria that served as a basis for the already described species, but it is fair to point out that, as stated, this side was not his primary object and that it is unreasonable to ask for everything. The result is an imposing book that will serve as an absolutely indispensable guide for every future student of the group. We hope that it will be extensively used by collectors in the tropics, who now can pay attention to a group about which they can instruct themselves at their own will and according to their needs..

Description: As long ago as 1926-27, during my last two years at Utrecht University, when studying the taxonomy and distribution of the Malaysian Bignoniaceae (Thesis 1927), I felt the need for a reference work in localizing inadequately labelled specimens. Material collected in the 19th century, especially that of BLUME, KORTHALS, JUNGHUHN, ZIPELIUS,¹ MOTLEY, HORSFIELD, etc. bear scant notes. Either these collectors did not realize the future value of full data or their notes were not mounted on the sheets in the herbarium and were often subsequently lost. I have also observed a tendency in some authors of tropical plant species in that period to underrate the importance of the locality because of their belief that tropical plants occurred everywhere in the tropics, i.e. were ubiquitous in the plant-geographical sense. Sometimes the collectors were natives accompanying expeditions, who did not make notes, e.g. JAHERI, ACHMAD, etc. Hence, it is often very difficult to trace the exact origin of specimens. KORTHALS’S plants, for example, are mostly labelled merely: ‘Borneo’. This botanist, however, described the parts of Borneo in which he collected and an extensive printed record of his travels is in existence.

Description: Though the new names published in Thunberg’s “Florida” have been entered in the Index Kewensis, few botanists have tried to verify the status and synonymy of the new species proposed in this 2-thesis booklet. Thunberg’s names were entered in Juel’s “Plantae Thunbergianae” (1918, 412 pp.). The diagnoses are generally too short and vague to allow a definite opinion. Only Schott, Mueller Arg., and F. E. Wimmer have examined material of resp. the Araceae, Euphorbiaceae, Campanulaceae.

Description: This paper presents the results of the examination of a fairly big collection of mollusca from the island of Mandul, north of Tarakan, East-Borneo. The material was collected by Dr. Van Holst Pellekaan while investigating the geology of Mandul in the service of the “Bataafsche Petroleum Maatschappij” (Royal Dutch/Shell). It was sent to Prof. K. Martin of Leyden for closer examination, and afterwards was embodied into the collections of the Leyden Geological Museum. Prof. Martin recorded the results of his preliminary examination, which excluded the bivalves, in a report to the “Bataafsche”, dated 12th January 1917. He came to the conclusion that the fossils were of a Pliocene age.

Description: The small collection of tiger-beetles, belonging to the genus Cicindela, which is the subject of this paper, was made by Dr P. Wagenaar Hummelinck during his visits to the Lesser Antilles and the adjacent South American mainland coast in 1936-’37 and 1948-’49. The greater part of the material has been deposited at the „Zoölogisch Museum” of Amsterdam and the „Rijksmuseum van Natuurlijke Historie” at Leiden. Some specimens (14 C. auraria, 10 C. graphiptera and 9 C. trifasciata) were presented to the collections of the American Museum of Natural History, British Museum, Deutsches Entomologisches Institut, Hope Department of Entomology at Oxford, The Imperial College of Tropical Agriculture in Trinidad, Institut Royal des Sciences Naturelles de Belgique at Brussel, Musée National d’Histoire Naturelle at Paris, Natural History Museum of Jamaica at Kingston, United States National Museum, and the Zoological Museum (including the collection E. Suenson) at Copenhagen, whose keepers kindly entrusted me with some material included in this study. The specimens from the U.S. Nat. Mus. were presented to Amsterdam, those from the Amer. Mus. to Leiden.

Description: Le texte contient l'explication de la carte, des profils et du tableau stratigraphique. La description lithologique fait mention d'une dolomitisation du Dévonien moyen, montant quelquefois plus haut, et de quelques poudingues dans le Dévonien supérieur. Un affleurement probablement du Dévonien inférieur dans un facies gréseux et fossilifère, est exceptionnel dans les Pyrénées. Dans la tectonique on a essayé de faire une évaluation des influences alpines et hercyniennes séparément. Puisque le métamorphisme de contact des granites de Foix et de Lacourt ne monte pas plus haut que le Gothlandien, leur âge reste incertain, quoique des dykes et sills acides traversent le Carbonifère. La minéralisation due au granité ne monte nul part plus haut que le Dévonien.

Description: La région que j’ai étudiée et relevée est située dans les Alpes françaises, à environ 4° longitude est et 50°15’ latitude nord, et à environ 2000 mètres d’altitude. Elle fait partie de la chaîne dite „chaîne de Belledonne” qui s’étend des massifs de Beaufort et du Grand Mont dans le N N E jusqu’à ceux du Taillefer et de la Mure dans le S S W. Cette chaîne forme du point de vue géographique comme du point de vue géologique le prolongement méridional de la chaîne des Aiguilles Rouges et de la chaîne du Mont Blanc. Celles-ci font partie de la zone externe des massifs cristallins des Alpes, dont le prolongement en Suisse est connu sous le nom de „massifs centraux des Alpes”. On entend par là les chaînes anté-alpines, et principalement hercyniennes des Alpes, constituées de roches du Houiller d’une part, de formations antérieures d’autre part, et recouvertes enfin de séries d’âges mésozoïque et permien. Dans le sud, cette chaîne hercynienne se divise de nouveau en deux branches, dont la plus orientale, celle des Grandes Rousses, aboutit à la partie déversée vers l’est, dans le massif du Pelvoux. Taillefer et la Mure forment le pivot le plus avancé de cet arc, et en effet ce dernier massif disparaît partiellement vers le S W sous le manteau sédimentaire du Dévoluy (cf. fig. 1). Le massif de Belledonne proprement dit, avec son point culminant: le Grand Pic de Belledonne, qui atteint à quelques mètres près les 3000, forme le tronçon central de cette chaîne et se trouve à quelques kilomètres à l’est de Grenoble dans le département de l’Isère. Il est limité à l’ouest par l’Isère et le Drac; au sud par la Romanche; à l’est par l’Eau d’Olle et au nord par la vallée de Laval et le Col de la Coche. Les Lacs Robert sont à peu près situés au centre du Massif de Belledonne, dans un cirque encoché dans le ralliement méridional de la chaîne occidentale à la chaîne principale du massif. Cette chaîne principale, comprise entre le Jasse Bralart au N et le Petit Vent au S, limite la région levée à l’est, tandis que la Botte et le lac Achard la limitent au sud. A l’ouest elle s’arrête au pied de la Croix de Chamrousse, le pivot méridional, et du Grand Eulier, le contrefort septentrional de la chaîne secondaire; et au nord audessus de la Prairie de l’Oursière. Cette région a une largeur de 3 km et une longueur de 4 km environ. Le Grand Sorbier dans la chaîne principale, avec ses 2522 m. en est le point culminant. L’impraticabilité du terrain fixa des frontières plus ou moins naturelles au lever. En particulier le flanc E de la chaîne principale, qui domine la vallée de Baton, à part quelques sentiers, n’est pas accessible sans danger, à cause du mauvais état de la roche schisteuse. Il en est de même pour la pente occidentale du Grand Eulier et du Casserousse, tandis que le flanc méridional du Petit Vent et de la Botte est un des versants de la gorge profonde de 2000 m. où coule la Romanche. C’est à cela qu’est dû le nombre restreint d’observations faites sur quelques parties de la périphérie.

Description: The days of big game seem to be numbered. Lists of mammals recently extinct are growing longer and longer and many more species are in danger of extinction. Of course, the last world war has hastened the fate of several species of animals. Eastern Asia and the Pacific region without doubt have suffered most in this respect. For example, the number of Javanese Rhinoceros, Rhinoceros sondaicus DESM., has diminished to such extent that survival seems hardly possible, owing to the aftermath of the Pacific war, which put out of action all painstaking measures of protection. Even before the last war two Asiatic species of deer were on the list of nearly extinct animals, viz. the Milu and Schomburgk’s Deer.

Description: This paper deals with the investigation of soil samples taken near Terhorne on the North-East shore of the “Sneeker Meer”, an expanse of water in the province of Friesland. (see fig. I) According to the geological map, the peat around this large body of water is covered by an 1—4 dm thick layer of young marine clay, but at the place where our samples were taken, the peat reaches the surface. A series of samples were collected from the whole depth of this peat-deposit (see diagram I). The surface lies here 0.35 m below the level of the sea. (As the sealevel is taken the N.A.P., the average height of the water level at Amsterdam.) At a depth of 2.15 or 2.20 m the borer reached the underlying sand. It proved impossible to penetrate with the borer used by us more than 5 to 10 cm into the sand. This sand (diagram 1a, which shows the lowest part of diagram I on an enlarged scale) proved to be of a red-brown colour.

Description: The borings, on which this study is based, were made within a radius of circa 5 miles around Opeinde, a village in the province of Friesland near the Friesland-Groningen border.

Description: The following is an abstract of my notes made during the sessions of the Section for Nomenclature at the 7th International Botanical Congress at Stockholm. The Congress lasted, officially, from 12 till 20 July, 1950. The Section for Nomenclature, however, began to meet on July 7. I wish to state that this review has no authority or official capacity. I made notes for private use and because it seemed useful, on further consideration, to inform the Staff and collaborators of the Flora Nalesiana.. of the changes in the Rules adopted by the last Congress, it was thought best to publish a review here, pending the official publication of the new Rules as a whole. I am told that an official note or communication dealing with the results obtained by the Section for Nomenclature is being prepared and will appear in the first Nuntius Phytotaxonomicus, the new periodical to be issued by the International Bureau of Plant Taxonomy, Secretary Prof. Dr J. Lanjouw at Utrecht.

Description: Ladies and gentlemen! To-day 133 years ago, as you all know, ” ’ s Lands Plantentuin ‘ was founded under the direction of Professor Reinwardt. To-day, however, is the first time that ” ’s Lands Plantentuin“ celebrates its anniversary as ‘Kebun Raya Indonesia’, under the changed circumstances following the transfer of Sovereignty on December 27, 1949.

Description: It is remarkable that, though on several occasions rather full accounts have been given of the history and activities of the Botanic Gardens at Bogor (Buitenzorg), ”Kebun Raya Indonesia”, up till now nothing comparable has been published on it’s Mountain Garden Tjibodas. This is the more striking as the establishment of a guesthouse annex biological laboratory in the Mountain Gardens by Melchior Treub, in 1890, which gave Tjibodas a definite claim to be recognized as a scientific institution, has sometimes been declared to be one of the greatest achievements in Treub’s period of office.

Description: This important book, written by C.A. Gardner after 30 years of field study and several years of preparation, deals with 420 species of grasses of which over a hundred have been provided with a plate, by which the habit and important details are shown. Especially the drawings of various parts of the spikelets are very skilful, instructive, and of the utmost importance for students of critical genera. There is an introductory part giving a general survey of the grass vegetation of W. Australia. It is a revelation to see that so many introduced and naturalised species had to be included; this striking invasion of 132 species affects a great change in the original vegetation.

Description: Dr Kostermans points our attention to an article by W.H. de Vriese, in Tijd.Nat.Geschied. & Phys. 12, 1845, p.60, in which was noted that Hasskarl’s Catalogue of the Botanic Gardens, Buitenzorg, was issued Oct. 1844.

Description: On March 7, 1953 the Rijksherbarium suffered a severe loss by the sudden death of its honorary co-operator Dr. D. F. van Slooten, the wellknown specialist particularly of Dipterocarpaceae. To honour his memory the following lines may serve as an obituary note. Dirk Fok van Slooten was born in Amersfoort on 17 March 1891. In the local gymnasium his biology teacher was the later Prof. A. Pulle, who was again his master at the University of Utrecht where he was matriculated in 1910. His doctor’s thesis of 1919 was dealing with the Combretaceae and Flacourtiaceae of the Dutch East Indies.

Description: For this study which was suggested to me and promoted by Dr R. A. Maas Geesteranus I had at my disposal the material of the “Rijksherbarium” at Leiden, the herbaria of the Universities at Amsterdam, Groningen and Utrecht, and those of the “Koninklijke Nederlandse Botanische Vereniging” and the “Natuurhistorisch Museum”, Maastricht. I wish to express my thanks to the directors of these institutions for putting the material at my disposal, and above all to the staff of the “Rijksherbarium”, who gave me a great deal of valuable help, especially Dr Josephine Th. Koster, Dr Maas Geesteranus and Dr S. J. van Ooststroom. I am indebted to Dr H. C. D. de Wit for the solution of some intricate nomenclatural questions, to H. J. T. Tammel for drawing the figures. Thanks to the presence of the herbarium of Persoon in the “Rjjksherbarium” at Leiden, I was able to arrive at a better interpretation of a number of species described by him. This was especially important for the reason, that Persoon’s “Synopsis Fungorum” of 1801 is the “startingpoint” of nomenclature in the Gasteromycetes.

Description: In this paper I intend to give a review of the genus Erycibe Roxb. in. which all the names published in the genus will be accounted for. The representatives from Malaysia have been dealt with more extensively in the revision of the genus in Flora Malesiana, Ser. I, Vol. 4, 4th instalment, 1953, pp. 404—431. — Technical descriptions of new taxa have been published in another paper in Blumea 7, 1953, pp. 310—319. In the present paper the literature will be published more extensively than in Flora Malesiana; besides I have included citation of all type specimens. The extra-Malaysian species have been studied less extensively than the Malaysian ones, but as I have seen nearly all the types, some notes are inserted which will be, I hope, useful for future study of the genus. Particularly the specimens from the Indian Peninsula need closer study.

Description: The following new species of Terminalia will be included in the forthcoming account of the Combretaceae for the Flora Malesiana where their respective positions in the key will indicate more clearly their relationship to already described species. Terminalia capitulata Exell, sp. nov.

Description: The editor has received the first and second fascicle of a treatise of the vascular plants of West Virginia. According to the preface this flora, when complete, will present descriptions, illustrations, geographical data and other information, particularly of local interest for the approximately 2000 species found growing without cultivation in that State. The first part contains the Pteridophyta, Gymnospermae, and Monocotyledoneae, the second part the Dicotyledoneae, p.p. (Saururaceae-Leguminosae). Keys are given for genera and species. The rather short descriptions are completed by many for the greater part original line drawings. Nomenclature and sequence are those of the 8th edition of Gray’s Manual, 1950, by M. L. Fernald.

Description: The first result of this survey of the wide genera which have endemic species in New Caledonia is certainly to confirm the impression that there is indeed a noteworthy geographical association between Madagascar and that island, even if it is only a particular aspect of a more general relationship between Madagascar and Australasia as a whole. But the survey gives prominence also to another point, namely the unexpectedly small part that tropical Africa plays in the distribution of the genera reviewed. It almost seems as if there is some factor of exclusion affecting that great region, and there is no indication of any corresponding degree of relation between tropical Africa and New Caledonia such as has been detected between the latter and Madagascar.

Description: In the “Mikrographie des Holzes der auf Java vorkommenden Baumarten” I described 991 kinds of wood. Several of these belong to large genera, the majority to small. I found remarkably wide variations in the wood-anatomy of several specimens belonging to a single species of a large genus. These intraspecific differences in large genera are generally larger than interspecific differences in small genera. When identifying species by means of wood-anatomical characters, the wide intraspecific variability in large genera obstructs identification whereas in small genera identification is usually relatively easily executed. As a result, it is much easier to compose a key to the species in a small genus than in a large one. In my key to the Javan woods (Anatomische Bestimmungstabelle für die javanischen Hölzer, 1940, 83) it is repeatedly demonstrated; also in Mikrographie passim that taxonomic relationships are often blurred by this peculiar circumstance.

Description: On a private collecting trip to the Netherlands Antilles, in the winter of 1948—1949, I had the opportunity of studying an infestation of the sapodilla, caused by a well-known kind of fruitfly, Anastrepha serpentina, which, however, has never before been reported from these islands. The identification was kindly confirmed by E. McC. Callan, Imperial College of Tropical Agriculture, Trinidad; specimens were compared by him with material named by A. Stone, deposited with the collections of the I.C.T.A. My grateful thanks are due to the Department of Agriculture of the Netherlands Antilles for giving a financial support which made entomological work possible, and especially to Agricultural Superintendent B. A. Bitter, for putting at my disposal the facilities of the Agricultural and Experimental Gardens at Cas Corá.

Description: Comme la carte de la page 8 le montre le Massif du Saint-Barthélemy se trouve dans le Dépt. de l'Ariège à l'Est et au Nord de la rivière dont le département porte le nom et entre Foix et Ax-les-Thermes. Le terrain examiné est formé entièrement de roches paléozoïques ou plus anciennes, bordées au Nord, au Sud et à l'Est par des formations mésozoïques. Ce terrain est limité également de Paléozoïque au côté Ouest, le long d'une faille qui sépare le Massif du Saint-Barthélemy du Massif de l'Arize. De cette manière le Massif du Saint-Barthélemy est un des Massifs primaires Nord-pyrénéens: c'est-à-dire l'une des îles de roches paléozoïques dans le Mésozoïque, situées au Nord de la zone axiale, qui est entièrement constituée de roches paléozoïques. Les principaux Massifs Nord-pyrénéens sont de l'Est à l'Ouest: le Massif de l'Agly, du Saint-Barthélémy, de l'Arize, des Trois Seigneurs, de Castillon et de la Barousse. Il existe en outre encore quelques petits Massifs.
