Habitat and conservation
It is found on well-drained fertile soils in mixed dipterocarp forests. The largest concentrations of the trees are generally on ridge tops. It has a wide geographic range, with an estimated extent of occurrence (EOO) of 127,755 km2, but it is found only in a few sites, and has an estimated area of occupancy (AOO) of only 20 km2.

The species is threatened with habitat loss, and its remaining habitat is increasingly fragmented. Its range and population are declining, and of the nine collection localities, only five are thought to still support populations of trees. Its conservation status is assessed as endangered.
