The Prosea Programme (Plant Resources of South-East Asia) Naturalis
Jansen, P.C.M..
For PROSEA, internet seems to offer an excellent opportunity to widely distribute and disseminate information on the plant resources of SE Asia. The PROSEA databank contains several very useful databases for PROSEA clientele. As try-outs the following three units are available on internet at: http://www.proseanet.org – BIBWEB, short for bibliography on the web, based on PROSEA’S PREPHASE – a unique collection of references to grey literature in the fields of agriculture, forestry and botany from SE Asia. Each record contains a clear indication of the source of publication and the location where the publication can be consulted; – PHOTWEB, short for photo on the web, based on PROSEA’S PHOTFILE – all PROSEA line-drawings and a large collection of photographs...

A new pygmy leafmining moth, Stigmella tatrica sp. n., from the alpine zone of the Tatra Mountains (Lepidoptera, Nepticulidae) Naturalis
Tokár, Z.; Laštůvka, A.; Nieukerken, E.J. van.
Stigmella tatrica sp. n. is described from moths taken in the alpine zone of the Tatra Mountains in Slovakia. The new species is similar to several other montane species of Stigmella Schrank, 1802 in the S. aurella (Fabricius, 1775) group in external characters and male genitalia; its closest relative is S. dryadella (O. Hofmann, 1868). It is indistinguishable from S. tormentillella (Herrich-Schäffer, 1860) by the colour and pattern elements of the forewing; however, it differs in the male genitalia in the shape and number of cornuti, in the female genitalia by long apophyses with protruding ovipositor, and by COI barcodes. Immature stages are unknown, but Dryas octopetala L. (Rosaceae) is the possible hostplant. The long ovipositor suggests an unusual,...

Phylogenetic relationships among extinct and extant turtles: the position of Pleurodira and the effects of the fossils on rooting crown-group turtles Naturalis
Sterli, J..
The origin and evolution of the crown-group of turtles (Cryptodira + Pleurodira) is one of the most interesting topics in turtle evolution, second perhaps only to the phylogenetic position of turtles among amniotes. The present contribution focuses on the former problem, exploring the phylogenetic relationships of extant and extinct turtles based on the most comprehensive phylogenetic dataset of morphological and molecular data analyzed to date. Parsimony analyses were conducted for different partitions of data (molecular and morphological) and for the combined dataset. In the present analysis, separate analyses of the molecular data always retrieve Pleurodira allied to Trionychia. Separate analysis of the morphological dataset, by contrast, depicts a more...

F. A. W. Miquel, Netherlands botanist Naturalis
Stafleu, F.A..
The University herbarium of Utrecht dates traditionally from the year 1816 when a collection of about 3000 plants was bought from the professor of botany M. van Geuns (1735-1817). It is possible that other collections of dried plants were already owned by the University or at any rate by the botanic garden, before that time, but nothing is known about this. The small van Geuns herbarium, which contained collections made by J. D. Hahn, M. W. Schwencke and S. J. van Geuns, among others, may therefore be taken as the starting-point of the herbarium of the later Botanical Museum.1)*) The period, however, was not one of great botanical activity at Utrecht and the botanist who succeeded van Geuns as professor of natural history and rural economy, Jan Kops, did...

A revision of the family Leeaceae Naturalis
Ridsdale, C.E..
A world wide revision of the family with a general discussion of the systematic position, the affinities within the family, the morphology of leaves, flowers, and seeds, the chromosome number, and the geographic distribution. Types of ruminate endosperm of the seed, previously unknown in the family, are illustrated and new types of pearl glands of the leaves are described. A single genus with 34 species is recognized, 32 of which occur in the Indo-Malesian area and 2 are restricted to the Afro-Madagascan area. One new species from New Guinea is described. There is a key to all species, followed by descriptions of the non-Malesian ones and full synonymy of all taxa together with distribution data. A complete revaluation of specific characters has resulted...

Ecological observations on the Genus Pleiocraterium in Gajoland, Sumatra Naturalis
Steenis, C.G.G.J. van.
As Prof. Bremekamp has dealt with the genus Pleiocraterium from the taxonomic point of view, I intend to supplement his exposition here with some observations on the ecology of these remarkable additions to the Malaysian mountain flora. Some of these observations have been included already in a general report on the results of the Losir expedition published in Dutch. As a further illustration I am giving two photographs taken from one of the two Sumatran species in its natural habitat. Altitude. Both species were found on the highest parts of the mountains only, viz. Pl. gentianifolium just below the summit of Mt Goh Lembuh, and Pl. sumatranum between our camp at the base of the central Peak of Mt Losir at c. 3250 m. and the summit of the latter at 3460 m....

Indonesische Leidensblumen Naturalis
Hallier, Hans.
Bei der Bestimmung der Passifloraceen von Borneo und zweier von Dr. JOH. ELBERT auf den kleinen Sunda-inseln gesammelter Arten stellte sich heraus, dass die Gattung Adenia einer gründlichen Neubearbeitung bedarf. Dadurch wuchs sich die folgende Bearbeitung der sicher bestimmten Arten zu einer selbständigen Abhandlung aus, die nicht mehr in den Rahmen der „Botanischen Ergebnisse der ELBERT’schen Sunda-Expedition” (siehe diese Meded. no 14, 22 u. 37) hineinpasste, für die sie ursprünglich bestimmt war. Wie in anderen meiner Arbeiten ¹), so finden sich auch hier wieder gelegentlich in Anmerkungen sprachvergleichende Betrachtungen über Pflanzen-, Tiernamen usw., da es mir zu einer gesonderten Veröffentlichung dieser Untersuchungen augenblicklich an Zeit und...

Homopteren von Java, gesammelt von Herrn Edw. Jacobson Naturalis
Melichar, L..
Herr Edw. Jacobson hat auf Java in den Jahren 1908— 1910 Homopteren gesammelt und mir die Bearbeitung des gesammelten Materiales übertragen. Die Jacobson’sche Ausbeute ist insoferne bemerkenswert, als dieselbe viele Mikrohomopteren enthält, welche von nichtfachkundigen Sammlern gewöhnlich nicht beachtet werden. Viele Arten, die von Jacobson auf Java gefunden wurden, waren bisher nur aus bestimmten Gegenden (Indien, Ceylon, Japan, Australien) bekannt und es ist die Konstatierung des Vorkommens dieser Tiere auf Java für die Kenntnis der geographischen Verbreitung dieser Homopteren von grossem Interesse und Bedeutung. Diese Tatsache liefert neuerdings den Beweis dafür, dass die jetzt isolierten Inseln der orientalischen Region seinerzeit ein zusammenhangendes...

Annotated checklist of the gall midges from the Netherlands, Belgium and Luxembourg (Diptera: Cecidomyiidae) Naturalis
Roskam, J.C.; Carbonnelle, S..
The gall midges are one of the most important groups of gall makers. Emerging larvae produce stimuli and the host plant responds by producing galls, fascinating structures which provide food and shelter for the developing larvae. Most gall inducing midges are host specific: they are only able to induce galls in a few, often related, plant species. A few species have different feeding modes: among them are saprophagous, fungivorous and predaceous species and some are used in biocontrol. We recorded 416 species in the whole area; 366 species are recorded from the Netherlands, 270 species from Belgium and 96 species from Luxembourg.

Minictena luteola, genre et espèce nouveaux de cténophore Cydippida méditerranéen a cinq types de colloblastes Naturalis
Carré, C.; Carré, D..
Minictena luteola gen. and sp. nov, is a small and unusual Cydippida ctenophore, found in the Mediterranean. Its general form and gastrovascular system with stomodeal canals, are similar to those of juvenile Pl.eurobrachiidae. It is characterised by: body semitransparent, yellowish; comb rows equal in length, in pairs from the tip to about the 2/3 of the body length; two apical and unequal pairs of rounded processes; tentacular sheaths of large size apposed to the infundibulum, opening aborally; tentacles with filiform tentilla bearing five types of colloblasts: three of them have a layer of refractive vesicles and a filament with only 1 or 2 spiral turns, the two others have no refractive vesicles and a filament with numerous spiral turns. This...

Sur deux nouveaux épicarides (Isopoda) parasites de Crustacés Décapodes Naturalis
Bourdon, R..
Le Dr. L. B. Holthuis, Rijksmuseum van Natuurlijke Historie, Leiden, que nous remercions très vivement ici, nous a envoyé récemment deux nouveaux Epicarides, l'un branchial, l'autre abdominal. Nous donnerons ci-dessous leur description. Le premier est un Bopyridae parasite d'un Scyllarus de la Mer Rouge. Cette récolte est particulièrement intéressante, car, ainsi que l'а remarqué M. Holthuis, elle constitue le premier cas de parasitisme connu chez les Palinura. Mais la capture apparaît d'autant plus exceptionnelle que le spécimen appartient aux Céponiens proprement dits, groupe dont les quelques cinquante espèces infestent exclusivement les Brachyura 1). A l'exception de Pseudione, phylogénétiquement peu évolué et encore très hétéroxène qui se rencontre...

De I.V.O.N.-inventarisatie Naturalis
Ooststroom, S.J. van.
In het eerste nummer van het Correspondentieblad gaf ik een overzicht van het werk van hot I.V.O.N. in het algemeen. Op verzoek van een aantal aspirantmedewerkers wil ik nu nog even iets over de practijk van het inventariseren laten volgen. Als basis voor de inventarisatie wordt, zoals reeds werd medegedeeld, gebruikt de Topografische kaart van Nederland 1 : 50.000. Deze wordt door verticale lijnen (de vouwen van do kaart) en horizontale lijnen (die erop worden getekend) in 40 kwadraten verdeeld van 5 x 5 km. Dit zijn de z.g. uurhokken, de eenheden voor de inventarisatie. Per uurhok worden nl. do daarin voorkomende plantensoorten in het veld genoteerd. Dit noteren geschiedt op gedrukte „hoklijsten”, verkrijgbaar bij het I.V.O.N. p.a. Rijksherbarium, afd....

Conspectus of the genera Radermachera and Fernandoa in Indo-Malesia (Bignoniaceae) Naturalis
Steenis, C.G.G.J. van.
In Radermachera 16 named species (among which three new) are keyed out. The genus Mayodendron is reduced to Radermachera; one new combination is made. One Phillippine species known only from a presumably lost type remains doubtful. About 34 names are put into synonymy, many of which for the first time. Species are listed and provided with references and critical notes; for most species the sheets examined are cited. Types are cited and all except one have been examined. Six names are excluded from the genus and are referred to other names. In the key to the species I have also included the species of genera similar to Radermachera, viz. Pauldopia and Barnettia, for the convenience of other workers. The African genus...

Lactuca tatarica (L.) C.A. Mey. op Rottumerplaat Naturalis
Meulen, H.T. van der; Ploeg, D.T.E. van der.
Lactuca tatarica (L.) C. A. Mey., in the Netherlands up till now known only as an adventitious species found in the harbour of Rotterdam, appears to have established itself in Rottumerplaat, a small island between Schiermonnikoog and Rottum (Westfrisian Islands). In 1967 about 200 plants were found; in 1968 this number has increased to at least 700.

A new genus and two new species of subterranean amphipod crustaceans (Hadziidae) from the Bahamas and Turks and Caicos Islands Naturalis
Holsinger, John R.; Yager, Jill.
Bahadzia, new genus, and two new species of amphipod crustaceans are described from anchialine caves in the Bahamas and Turks and Caicos Islands. One of the species is recorded from three caves on Grand Bahama Island and one cave on Great Abaco Island, whereas the other species is recorded from two caves on the island of Providenciales. The new genus is apparently more closely related to Metaniphargus and Saliweckelia than other hadziid genera in the peri-Caribbean region, but it also shares some important characters with Mayaweckelia.
