Asia-Tropical: Philippines (Philippines present), Luzon present, Palawan present
Malesia: Philippines (Luzon; Palawan, 4 collections).


The largest specimen is Foxworthy 684 from Palawan (MICH). Hooker described var. ß, but he cited no specimen and I have not found one so marked. De Vriese 41, wrongly cited by Hooker, is P. ramosii, as also Whitford 272 wrongly cited by Christ.
