1 This is the only Knema occurring in New Guinea (and known only from a single collection). Most specimens formerly recorded for the Philippines belong to K. glomerata, a related species differing in the finer reticulation on the upper leaf surface, bracteole median on the pedicel, and a ± convex staminal disc. In the Philippines K. tomentella is known only from Samar. 2 Specimens from Sulawesi may be reminiscent of K. celebica or K. glomerata.
