Often found in evergreen tropical broad-leaved forests or in subtropical forests, from 900 to 1500 m elevation. A neutral and shade-tolerant tree when young, usually growing on limestone. Seedlings and saplings grow very well under the shade of mother trees (FIPI 1996).
The IUCN reports that this species is "vulnerable" to extinction in the wild because the population is already very small and restricted in distribution, and could be devastated by a chance occurrence that could be caused by human action.
