Distribution
Asia-Tropical: Borneo present
Malesia: Borneo; collections from several localities.
Notes
v.A.v.R. in the Supplement to his Handbook describes the basal veins "uniting at or a little below the sinus", but in the specimens examined by me they usually end separately, though near together, their tips sometimes touching near base of pinnae.
