The photos show a female Ficus montana of the narrow leaf variety with  ripe fruits.

Narrow leaf varieties of Ficus montana have been  recorded from Kapit in Central Sarawak and Samarinda in East Kalimantan, Indonesian Borneo  but they are not common.

These varieties are  rheophytic i.e. adapted to being regularly flooded by fast flowing streams.

All photos taken by Ripin Forestry  at Kampung Tongan Baru, Melawi, near  the Gunung Naning Protected Area in the hills of West Kalimantan, Indonesian Borneo.
