In undisturbed to slightly disturbed mixed dipterocarp forests up to 700 m
altitude. On alluvial sites near rivers and streams, but also on hillsides and
ridges. On sandy to clay soils, also on limestone.
The wood is used (keledang wood). In Sarawak, the timber is traded under the name Bintawak and locally
used for indoor constructions and for making household utensils and tool-handles. The bark is locally
used as rope for backpacks. The leaves are burned, and mixed with coconut oil used against boils
and itch. The fruits and seeds are edible.
