A Monograph of the Vochysiaceae III. Qualea Naturalis
Stafleu, F.A..
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...

A "new" Nitidulid Beetle from Sumatra Naturalis
Jong, C. de.
Some time ago I was asked to identify a fossil coleopteron which had been found in the drill cuttings of an oil well in the Southern part of Sumatra. As the fossil is only a few millimetres long it may be mentioned as an amazing fact that so small an object has been found during rather rough work like oil drilling. The details of the locality as given by Mr. A. Wright Jr. of the N.V. Standard-Vacuum Petroleum Maatschappij are as follows: "The well is one of our Kaja wells, a wildcat well located 3.3 kilometres N. 300 E. from the northeast edge of the Djirah oilfield. The drill cutting was obtained from a depth of 1930 feet subsea. Although, in drill cuttings, there is a certain measure of uncertainty as to the exact level of derivation, we have sufficient...

A partial revision of the genus Metabelba grandjean (Oribatei, Acari) Naturalis
Hammen, L. van der.
INTRODUCTION The genus Metabelba was created by Grandjean in 1936 for Belbidae of which the solenidions of tibiae II and III are coupled with protective hairs, but of which the solenidion of tibia IV is free, long, and tactile. The genus belongs to the group of rather small species that are never covered with foreign material, but of which the cerotegument is very thick, especially on the moniliform legs, whilst the adults often bear the larval and nymphal skins. The species have three or four lateral apophyses : one (which is not always present) between leg I and leg II, two between II and III, and one between III and IV. We have been in doubt as to the nomenclature of these apophyses, for although they have generally been regarded as tectopedia, they do...

A review of the genus Erycibe Roxb Naturalis
Hoogland, R.D..
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...

Action de divers constituants chimiquement définis du miel et des extraits d'abeille sur des cellules colchinées du blé National Institute of Agronomic Research
Rebert, A.F..
Parmi les constituants chimiquement définis du miel, des extrait de pollen ou d'abeilles, les vitamines E, K et l'inositol se sont révélés comme de puissants freinateurs de la croissance (jusqu'à 50%) des plantules de blé et comme des corps anti ou problastiques (selon les doses) vis-à-vis des tumeurs colchiciniques du blé ou des phytocarcinomes à Pseudomonas tumefaciens (parfois fonte tumorale). Le groupe des naphtoquinones où nous trouvons le phtyocol (antagoniste possible de la tuméfaction dans les tuberculoses évolutives) comprend également les variations métaboliques des vitamines E et K dont les propriétés physiologiques, en dehors des phénomènes classiques mériteraient une étude plus approfondie.

Adubação da mandioca (Manihot utilissima Pohl.) I: ensaio em areia lavada (Nota prévia) Anais da ESALQ
Malavolta,E.; Coury,T.; Graner,E. A.; Pacheco,J. A. de C.; Brasil Sobr.,M. O. C. do.
This paper deals with the preliminary results of a sand culture experiment carried out to obtain physiological bases to study the fertilization of cassava in the State of São Paulo. On the other hand, the authors are interested in the possible influence of mineral nutrients in the quantity and quality of starch. Cassava (Manihot utilissima Pohl.), "Branca de Sta. Catarina" variety, was grown under the following treatments: NO PO KO, NO P1 K1, N1 P0 Kl, NI P1K0, N2 p1 Kl N1 P2 K1 and N1 P1 K2. A striking response to phosphorus was observed among the treatments. However, once secured the necessary phosphoric level to the plant, the production becomes limited by nitrogen; in other words, increase in yield can be accomplished only by raising the nitrogenous...

An attempt at a natural classification of certain Zosteropidae of the Indo-australian Archipelago Naturalis
Mees, G.F..
The family of the Zosteropidae encloses, besides the very large and uniform genus Zosterops, a number of aberrant forms, especially in the East Indian Archipelago, that, though doubtless closely related to Zosterops, are too distinct to be united with this genus without objection. Several authors have engaged themselves with the problem of the classification of these forms, without arriving at a definite conclusion (cf. Hartert, 1897, Lophozosterops; Stresemann, 1940, p. 66, Pseudo zosterops). The inclusion of many of these forms in the genus Zosterops, as propagated by Hartert, and by Chasen (1935), is no final solution either, and later workers, such as Delacour & Mayr (1946), Delacour (1946), and Voous (1948), investigators who are certainly not in...

Analyse von C. J. Temmincks "Catalogue systématique" (1807) Naturalis
Stresemann, E..
Unter dem Titel „Catalogue systématique du cabinet d'ornithologie et de la collection de quadrumanes de Crd. Jb. Temminck. Avec une courte description des oiseaux non-décrits ... à Amsterdam, chez C. Sepp Jansz. MDCCCVH" gab der bald dreissigjährige C. J. Temminck ein Büchlein heraus, das dem Historiker der Ornithologie manch willkommenen Aufschluss erteilt. Der Autor selber hat in späteren Jahren diese seine erste Veröffentlichung nicht mehr erwähnt. Wegen ihrer Seltenheit ist sie den meisten Ornithologen der Folgezeit unbekannt geblieben, und einzig Hartlaub hat sich der Aufgabe unterzogen sie genauer zu studieren und die vielen neuen Vogelarten zu deuten, die Temminck im Catalogue" zwar sorgfältig beschrieben, aber nur mit französischen Namen belegt...
