A NEW SPECIES OF SCAPHIUM (STERCULIOIDEAE, MALVACEAE / STERCULIACEAE) FROM BORNEO

Abstract

Scaphium parviflorum P.Wilkie sp. nov. (Sterculioideae, Malvaceae/Sterculiaceae) is described and illustrated. The flowers are intermediate between the tubular flowers of Scaphium macropodum and the deeply lobed ones of Scaphium affine. However, Scaphium parviflorum differs from these species by its smooth to fissured or dippled and brown to grey-brown bark, small narrowly ovate to narrowly elliptic leaves and the presence of sparse minute flattened stellate hairs (resembling scales) on the midrib of the lower surface of the lamina.
