TL;DR: During a geographical survey of the genus Buxus in Malaysia I came across the name BUXus nitidus (Miq.) Hall, based on a plant from Sumatra, collected by Teysmann on the coast of Sibolga, and described by Miquel, Fl.
Abstract: During a geographical survey of the genus Buxus in Malaysia I came across the name Buxus nitidus (Miq) Hall ƒ Med Rijksherb n 37 (1918) 16 This is based on a plant from Sumatra, collected by Teysmann (HB 769) on the coast of Sibolga, and described by Miquel, Fl Ind Bat Suppl (1861) 444—445, as the representative of a new genus: Austrobuxus nitidus Miq, provided with a generico-specific description
This genus had tentatively been reduced by Bentham & Hooker (Gen P 3, 1880, 280) to another genus of the Buxaceae, viz Sarcococca, notwithstanding its decussate leaves; more specially to S sumatrana Bl Mus Bot L B 2 (1856) 191, of which I could not find the type; no material was cited with its description
TL;DR: The Malesian species of the predominantly New Caledonian genus Austrobuxus were revised and two new species are recognized, notable for the very small fruits and the latter for the teeth-like glands along the leaf blade margins, unique within the genus.
Abstract: The Malesian species of the predominantly New Caledonian genus Austrobuxus were revised. Three species are recognized. Austrobuxus nitidus is widespread from south Thailand to Borneo. Characteristic for this species are the very short papillae of the caruncle. The caruncle papillae are much longer in the other two, newly described species. Austrobuxus celebicus sp. nov. is endemic to Sulawesi, where it is found on ultramafic soils, and A. dentatus sp. nov. is an endemic species of western New Guinea. The former is notable for the very small fruits and the latter for the teeth-like glands along the leaf blade margins, unique within the genus.
