Notes: Notes W.J.J.O. de Wilde (2000). Flora Malesiana, Series 1, volume 14, pp. 445 & 446 restricted this species to three known collections, Ledermann 10131 (type), Ledermann 9110 (both from the East Sepik region) and Croft et al. LAE61173 from the Gulf region. In this account, we have applied the same broader species concept as used by D.B. Foreman, 1978, Handbooks of the Flora of Papua New Guinea, vol. 1, p. 192).
