2 SAN 9957, from Sabah, has extremely large male buds, 7 by 5.5 mm, with coarse hairs 1-5(-2) mm long; anthers 13. 1 Knema lunduensis is related to K. latericia, K. furfuracea, and K. per-coriacea and is more or less intermediate between the first two species mentioned. Knema latericia generally has a more slender habit, with smaller leaves, often a convex or mam-millate staminal disc, and smaller fruits with shorter indumentum; K. furfuracea has cordate leaf bases, though the leaf base in K. lunduensis is occasionally subcordate in larger leaves; K. percoriacea has a differing general habit, with more coriaceous leaves. Some specimens included in K. lunduensis come close to certain stout, large-fruited forms of K. latericia subsp. ridleyi.
