Forests, on yellow sandy or ultra-basic soils; at elevations from 1,000-2,000 metres in Malaysia. Montane forest at elevations from 1,000-3,350 metres.

The seeds or nuts are cooked and can be dried and ground into a powder and then used for thickening stews or mixed with cereals for bread. The bitter tannins are washed out in running water. The roasted seeds are used as a coffee substitute.

Can be grown by seedlings.
