Asia-Tropical: Malaya (Peninsular Malaysia present), Pahang present, Panching present
Malesia: Malay Peninsula (Pahang, at the type locality and Panching, 20 km west of Kuantan, southern Kelantan).
The type was collected in forest at the foot of limestone cliffs. It has very thin fronds and few hairs between veins on the upper surface, but a small plant from the same locality is copiously hairy in that position. The type has also fairly numerous forked veinlets in areoles. Specimens from Panching (an isolated limestone hill free of forest) are firmer in texture, very hairy between veins on the upper surface and have rare forked veinlets in areoles.
