| Of the 5 genera mentioned in the title a revision is given of the species of the Malesian region. Critical notes are made on delimitation, subdivision, and/or distribution of Carissa, Melodinus, and Chilocarpus; Neokeithia is reduced to Chilocarpus which genus exhibits an unusual array of variation in fruit structure. Keys to the Malesian species are presented of Melodinus, Leuconotis, and Chilocarpus. The keys are followed by an enumeration of these species; each species is provided with a brief synonymy and an account of its distribution and ecology. Essential extensions of previous knowledge of distribution are documented briefly by citing select collections. Various reductions of species are made. In Melodinus 2 new species are described, in Leuconotis... |

| A revision with keys to and descriptions of the 5 Malesian species of Ochrosia Juss. (2 n. sp.) and 6 of Neisosperma Raf. Several species names are reduced. All types are mentioned. A selected number of specimens is cited; a full list of collectors will appear in the series Identification Lists of Malesian Specimens. Bleekeria Hassk. and Excavatia Markgr. are reduced to Ochrosia. In the note under Ochrosia there is a full discussion of the differences between this genus and Neisosperma, especially of the fruit for which some old types were microscopically examined. In Ochrosia the fruits are apocarpous, but in one species they are connate for one third, while in a new species from Flores they are united into a syncarpous, 2-celled drupe. In spite of the... |

| An account of Alyxia Banks ex R. Br. in Malesia in which in all 57 species are distinguished, eight varieties (7 new), and one new subspecies. Twelve new species are proposed, one new combination, and one new name. Several species have been reduced. Two genera have been merged with Alyxia, viz. Paralstonia Baill. and Discalyxia Markgr. The species are grouped according to their presumed natural affinity in 12 series and 2 subseries. Keys are given to all series, subseries, species, and varieties. The revision is concluded with a list of names of insufficiently known species and one of excluded names. |

| Glabrous trees, shrubs or, for the greater part, vines. Leaves decussate, simple, entire, penninerved, exstipulate, mostly provided with fine, pellucid lines (spicular cells) parallel to the secondary nerves and then bearded on fracture. Spikes ramified or simple, axillary or often cauline, dioecious, each one with 2 opposite basal scales and several collars containing moniliform hairs and sessile flowers, either numerous spirally arranged male ones below a ring of some sterile female ones, or a ring of few fertile female ones. ♂ Flower: a claw-shaped, transversely splitting perianth and a central stamen with 2 (in G. gnemonoides one) apical, yellow microsporangia that open by an apical median split. ♀ Flower: a fleshy outer envelop (‘perianth’) and 2 thin... |

| Gnetum neglectum war nicht nur, wie der Name andeutet, bis zu Blumes Zeit übersehen worden, sondern es wurde von Späteren wiederum verkannt, wie ich in Bull. J. B. Buitenzorg 3. Ser. 10 (1930) 474 näher ausgeführt habe. Die echte Art taucht verhältnismässig selten in den Herbarien auf. Sie ist eine Pflanze der Alluvialwälder in Borneo. Vegetativ ist sie ausgezeichnet durch derbe, grosse, lanzettlich-elliptische Blätter mit Träufelspitze, deren Seitennerven auffallend weit voneinander abstehen. Die Blütenstandsachsen sind ziemlich zart und wenig verzweigt, die Samen klein, ungestielt und etwas gelblich. Merkwürdigerweise war in den reichen Sammlungen aus Borneo, die mir bisher zu Gesicht kamen, diese Art immer nur durch ♀ Pflanzen vertreten. Jetzt sind zum... |
