Morphology

1 Knema glomerata is the most common species of Knema in the Philippines. It is close to K korthalsii, which differs in 20-35 pairs of lateral nerves, somewhat larger flowers, in male with an average of 18 anthers, and a more pronounced mammilla on the staminal disc. It is also close to K tomentella (for differences see the key), but this latter species possibly does not occur in the Philippines. 2 The specimen S 24419, from Sarawak, is highly questionable as regards the locality, far away from the main area of the species in the Philippines. It has male flowers, which agree with K. glomerata. 3 Knema glomerata is variable in the amount and length of the (deciduous) hairs on flowers, twig apices, and petioles: in a woolly form, the hairs are relatively long, up to 1 mm, and longer persistent, on the lower leaf surface it is denser; short-haired specimens may resemble K cinerea, which differs in a flat staminal disc, a very short indumentum on the flowers, and the perianth being usually creamy or greenish inside, not pinkish red.
