Taxonomy

2 Apparently the species is restricted to Peninsular Malaysia. The records for Borneo mentioned by Sinclair ( ) are now referred to K. glaucescens. Shah & Kadim 526 (Peninsular Malaysia), after which Sinclair drew the emended description of the female flowers of K. communis, is now referred to K. glaucescens as well. 1 Knema communis resembles K. glaucescens, a species also with subpersistent indumentum on the lower leaf surface. The resembling K. malayana has larger and longer pedicelled male flowers, with 9-13 anthers, and a different indumentum on the lower leaf surface.
