1 Knema plumulosa is related to K. intermedia, a species with which it has the distinct mammillate staminal disc in common; K. intermedia differs in its shorter, not lanose indumentum, thinner twigs, smaller leaves, the perianth non-persistent in fruits, and in the absence of a disc at the base of the perianth. According to Sinclair both species have stilt-roots if growing in wet soil. 2 By the woolly indumentum of the young twigs, and the glabrous coriaceous leaves, the species resembles K. percoriacea from Borneo, which differs in the flat staminal disc, absence of perianth disc, and perianth not persistent under the fruit.
