Description: Besides the Umbelliferae of the Netherlands Indies proper, also those of the Malay Peninsula and the non-Dutch parts of Borneo and New Guinea have been taken up in this revision. The materials examined belong to the following Herbaria: (B) = the Herbarium of the Botanic Garden, Buitenzorg. (BD) = the Herbarium of the Botanical Museum, Berlin\xe2\x80\x94Dahlem. (BM) = the Herbarium of the British Museum of Natural History, London. (E) = the Herbarium of the Botanic Garden, Edinburgh. (G) = the Herbarium of the University, Groningen. (K) \xe2\x80\x94 the Herbarium of the Botanic Gardens, Kew. (L) = the National Herbarium (Rijksherbarium), Leiden. (NY) = the Herbarium of the Botanic Garden, New York. (Pa) = the Herbarium of the Java Sugar Experiment Station, Pasoeroean. (S) = the Herbarium of the Botanic Gardens, Singapore. (Sa) = the Herbarium of the Sarawak Museum, Kuching. (U) = the Herbarium of the University, Utrecht.\nMost of the herbarium materials were sent to Groningen to be examined there. Moreover I had the opportunity to work a few weeks in the Kew Herbarium and in that of the British Museum of Natural History in London.

Description: Referring to the identification of BRASS 5219 from Papua as a representative of the Verbenaceous Faradaya chrysoclada K. SCHUM. by E. BEER and H. J. LAM (Blumea 2, 1936, 225), Dr C. G. G. J. VAN STEENIS, the monographer of the Malaysian Bignoniaceae drew our attention to the possibility that this identification might be incorrect. It was suggested that the specimen and also all specimens hitherto known as Faradaya chrysoclada might be Bignoniaceous and might belong to Deplanchea tetraphylla (R. BR.) V. STEENIS, as all other Faradayas known are lianas, whereas F. chrysoclada was reported to possess the tree habit, as the Deplancheas.\nWe therefore asked on loan the materials of both species from the Herbarea at Berlin (B) and Kew (K), that from Berlin including the type specimen of Faradaya chrysoclada. Our thanks are due to the directors of the Herbaria of Berlin and Kew for kindly lending us the material desired.

Description: BLUME published Viscum monilliforme first with a short diagnosis in his \xe2\x80\x99Bijdragen tot de Flora van Nederlandsch Indi\xc3\xab\xe2\x80\x9c 13 (1825) p. 667, and later he gave a figure of it in his \xe2\x80\x9dFlora Javae\xe2\x80\x9c, plate 25 (1851?).\nIn the \xe2\x80\x9dBijdragen\xe2\x80\x9c we read: VISCUM MONILLIFORME, Bl. V: caule aphyllo inferne teretiusculo, ramulis artieulatis ancipitibus, articulis nudis, floribus verticillatis sessilibus (aff. V. opuntioidi). Crescit: in arboribus circa Buitenzorg vulgatissimum. Floret: omni tempore. Nomen: Mangando.

Description: Mr. BRASS\xe2\x80\x99S New Guinea collection has yielded valuable data to our knowledge of the Verbenaceae. He discovered one new genus (Archboldia), 3 new species (Clerodendron Brassii, C. populneum and Premna inaequilateralis) and some interesting additions to the area\xe2\x80\x99s of earlier described species, among which the rediscovery of Faradaya chrysoclada, and the discovery of two species new for South New Guinea (Premna sessilifolia and Teysmanniodendron bogoriense) and of one more for the whole island ( Glossocarya Hemiderma).

Description: The Charophyta of the Netherlands have been hitherto almost neglected. As far as I know only the following papers are dealing with the matter: VAN DEN BOSCH, R. B., in Ned. Kruidk. Archief 1, 1846, p. 100, p. 289. \xe2\x80\x9cII 1851 p. 225. both preliminary works to Prodromus Florae Batavae II, 2, 1853, p. 186\xe2\x80\x94189.\nDE VRIES, H., Flora van Nederland, in Alg. Statist, v. Ned. I, 8, 1870, p. 39.

Description: The present investigation has been carried out in the \xe2\x80\x9cBotanisch Museum en Herbarium\xe2\x80\x9d of the University of Utrecht. I wish to render to Dr. A. Pulle, the Director of the Institute, my most sincere thanks for the facilities afforded to me and for the interest in the progress of this work.\nI am also greatly indebted to the Directors of the Berlin-Dahlem, Brussels, G\xc3\xb6ttingen, Leiden and Paris Herbaria and to the members of their staff for the opportunity of studying in these Institutes the collections entrusted to their care and for their helpful advice. Special words of thanks are due to Dr. O. C. Schmidt (Berlin-Dahlem), Dr. R. Benoist (Paris) and Dr. Exell (South Kensington). To Mr. Wilmott (South Kensington) I am obliged for the information he gave me with regard to the genus Persea, and to Dr. Hochreutiner (Geneva) for the loan of the type specimen of Ocotea vernicosa. To the Brussels, Berlin-Dahlem, G\xc3\xb6ttingen, Kew, Leiden and Paris Herbaria I am indebted for the loan of specimens which I needed for the solution of various special problems.

Description: The Moraceous genus Clarisia was described by Ruiz et Pavon in 1794 in \xe2\x80\x9dFlorae Peruvianae, et Chilensis Prodromus\xe2\x80\x9d p. 128. This generic name must be rejected, if it is not placed on the list of Nomina Generica Conservanda, as in 1792 there had already been published a genus of this name by Pedro Abat In the list of genera recommended for placing on the list of Nomina Generica Conservanda (Kew Bulletin 1935 pp. 341-544). Mr. Weatherby mentions Clarisia R. et P. I quote here what he writes on Clarisia Abat: \xe2\x80\x9ePlaced by Sprengel, L. Gen. Pl. ed. 9, I. 202 (1830) in synonymy under Anredera Juss. (1789). He has apparently been followed by all subsequent authors who have noticed the name at all. I have not seen Abat\xe2\x80\x99s publication. If the date is correctly given by Dalla Torre & Harms and the genus adequately published, Clarisia R. & P. must be conserved if it is to be retained. \xe2\x80\x9dAs far as can be judged from literature no botanists have seen Abat\xe2\x80\x99s publication. This is not to be wondered, as Abat\xe2\x80\x99s paper was published in a scarcely spread periodical. I have tried to obtain this periodical in the Netherlands, in London and Paris but nowhere I could get hold of it. Thanks to the kind assistance of Prof. Cuatrecasas of Madrid I could receive a copy of this paper and a photograph of the plate from the original in the library at Sevilla. Abat\xe2\x80\x99s paper was published in \xe2\x80\x9dMemorias de la Real Sociedad de Medicina, y Demas Ciencias de Sevilla, Tomo Decimo. 1792. pp. 418- 438\xe2\x80\x9d. The name of the periodical was cited by Sprengel as \xe2\x80\x9dActa etc.\xe2\x80\x9d The word \xe2\x80\x99Acta\xe2\x80\x99 does not occur in the completely copied title of the periodical which I received from Prof. Cuatrecasas, so apparently Sprengel must have been mistaken. The publication is a communication made by Pedro Abat, Correspondiente del Real Jard\xc3\xadn Bot\xc3\xa1nico de Madrid, y Socio Botanico, to the Society mentioned in the title of the periodical.\nAbat begins his paper with a statement of the necessity of great exactness in the decription of plants which is of course still true and especially for the plants we are dealing with in this paper. Therefore I have started my present paper with the same words as Abat did nearly 150 years ago. In the first part of his paper, Abat gives an account of the literature dealing with his plant. He quotes the words of Hans Sloane on Fagopyrum scandens and concludes from Sloane\xe2\x80\x99s description that it is the same species as he (Abat) demonstrated before the Society. Then he writes extensively on Linn\xc3\xa9\xe2\x80\x99s Polygonum scandens L. His conclusion from the description of Linnaeus is that Polygonum scandens L. is not Sloane\xe2\x80\x99s Fagopyrum scandens, though Linn\xc3\xa9 placed the latter in synonymy under his Polygonum scandens. Sloane\xe2\x80\x99s plant of which he shew a living specimen, is according to him quite different from Polygonum scandens L. from which he had brought a herbarium specimen.

Description: In seiner Bearbeitung einiger von Glaziou in Brasilien gesammelten Convolvulaceen beschreibt Dammer (I) u.a. zwei neue Prevostea-Arten, P. capitata und P. sphaerocephala, welche der Beschreibung nach auffallende Unterschiede aufweisen mit den anderen Arten dieses Genus. Auch Dammer selbst spricht, wenigstens f\xc3\xbcr P. capitata, schon die Vermutung aus, es handele sich hier um Repr\xc3\xa4sentanten eines selbst\xc3\xa4ndigen Genus oder vielleicht einer neuen Sektion von Prevostea, weil er aufmerkt: \xe2\x80\x9eAn Genus novum? An sectio nova generis Prevosteae, inflorescentia bene distincta?\xe2\x80\x9d Aus einer Untersuchung der beiden Arten, welche die Direktion des Berliner Herbariums mir freundlichst zum Studium \xc3\xbcberliess, stellte sich nun heraus, dass wir die beiden Arten der Beschaffenheit der Bl\xc3\xbcte nach bei Bonamia unterbringen m\xc3\xbcssen. Hinsichtlich der Unterschiede zwischen Prevostea und Bonamia bemerkt Hallier (2, S. 530), dass ersteres Genus sich von Bonamia unterscheidet durch \xe2\x80\x9edie beiden a\xc3\xbcszeren, groszen, fein netzaderigen, h\xc3\xa4utigen, durchscheinenden, kreisherzf\xc3\xb6rmigen Kelchbl\xc3\xa4tter\xe2\x80\x9d. Bei den zwei Dammerschen Arten entsprechen die beiden \xc3\xa4usseren Kelchbl\xc3\xa4tter dieser Beschreibung keineswegs. Sie sind nicht auffallend verschieden von den anderen und zeigen eine Form, welche sich vielmehr an die vieler Bonamia-Arten anschliesst. Wohl treten im Habitus der Pflanzen einige Unterschiede mit den anderen Arten dieses Genus auf, besonders hinsichtlich der zu K\xc3\xb6pfchen am Ende der Zweige geh\xc3\xa4uften Bl\xc3\xbcten. Vergleichen wir dieses Merkmal nun aber mit den Verh\xc3\xa4ltnissen welche sich bei anderen Gattungen der Familie auftun, wie bei Evolvulus und Jacquemontia, dann stellt sich heraus, dass auch hier Arten auftreten mit k\xc3\xb6pfchen- bis \xc3\xa4hrenf\xc3\xb6rmigem Bl\xc3\xbctenstand. In meiner Monographie der Gattung Evolvulus (5) habe ich schon auf diese Spezialisation in der Beschaffenheit des Bl\xc3\xbctenstandes hingewiesen. Die Arten dreier Sektionen zeigen hier das genannte Merkmal. Diese Arten sind haupts\xc3\xa4chlich auf Brasilien beschr\xc3\xa4nkt, wo sie in den Campos Vorkommen. Auch bei Ipomoea besteht die Tendenz zur Bildung endst\xc3\xa4ndiger, \xc3\xa4hrenf\xc3\xb6rmiger Bl\xc3\xbctenst\xc3\xa4nde. Als Beispiel nenne ich Ipomoea echioides Choisy und I. Pohlii Choisy. Unten werde ich noch die Gelegenheit haben auch bei Jacquemontia auf \xc3\xa4hnliche Verh\xc3\xa4ltnisse hinzuweisen.
