Taxonomy

3 The only collection from the Philippines (Zamboanga Prov., Mindanao), FB 23328, probably belongs to K. cinerea; it is in fruit, 1.8 by 1.3 cm, fruiting pedicel 12-13 mm long, lower leaf surface with minute persistent scale-like hairs. The indumentum of the resembling K. glomerata, common in the Philippines, consists of much softer stellate hairs, which are either persistent or early shed; the flowers and twig apices in K. glomerata have longer, woolly dendroid hairs, up to 0.5 mm long. 1 The lower leaf surface of specimens from the Lesser Sunda Islands is densely scale-like hairy, whereas in Sulawesi the surface is more sparsely, fine-stellately hairy. 2 Knema cinerea is related to K. stenophylla, K. patentinervia and K. glauca with almost similar habit and flowers, the latter species mainly differing in the lower leaf surface with very weak stellate hairs, early glabrescent, and larger glabrescent fruits. Specimens of K. glauca from Bali have small fruits, 2.2 cm long, and may resemble K. cinerea.
