About 40 species of the largely tropical, montane genus Weinmannia occur in Malesia and the Pacific belonging to two sections. Section Fasciculata is largely Malesian, extending eastwards to Fiji, and sect. Leiospermum is largely Pacific, occurring as far west as Papua New Guinea. The structure of the inflorescence provides previously unrecognised characters of taxonomic importance, especially at the sectional level. Because of the high levels of local endemism, species accounts for the whole region are divided into four parts. Descriptions, illustrations and distribution maps are provided here for four species: W. fraxinea, a widespread ochlospecies; W. clemensiae, a local endemic on ultramafic substrates in Sabah; , from Borneo and Sumatra, and W. hooglandii H.C. Hopkins & J.C. Bradford, sp. nov. from Peninsular Malaysia.
