Florae Malesianae Precursores XXVIII. The genus Vaccinium in Malaysia by H. Sleumer (Rijksherbarium, Leiden) (Issued 1. XII. 1961) Within the Vaccinium L. this revision of its — which genus Malaysian species comprises more than half of the total number of species of the genus — is the last in series of a modern treatments made for North America by W. H. Camp, for the Pacific area by C. Skottsberg, and for tropical America and tropical Asia by the present author. The work formerly done in Malaysian Vaccinium has been limited to islands, as that by J. J. Smith and Schlechter for a part of New Guinea, by Copeland f. for the Philippines, and by Amshoff for Java, with the shortcomings necessarily connected with such too local work. The sections for the proposed Malaysian species in my general system in 1941 have been found still useful and here nomenclatural are kept except a change in one section and the expansion in species due to the large amount of indetermined material collected in Celebes and especially in New Guinea. The work the basis of of Vaccinium present gives my treatment to appear in the Flora Malesiana, where descriptions of all species in English language will be found; it offers a key to the sections and species, the Latin descriptions of the and the localities of all taken from number new taxa, species a large of herbarium specimens which have been kindly lent through the courtesy of the Directors of the following institutions: Arnold Arboretum (A) Leyden (L) Bogor (BO) Lae (LAE) Canberra (CANB) Melbourne (MEL) Edinburgh (E) New York (NY) Florence (FI) Stockholm (S) Gray Herbarium (GH) Kuching (SAR) Kepong (KEP) Singapore (SING) The material preserved in British Museum Nat.
