Relatively small pockets of the original tropical evergreen forests remain, which is where this species grows.

Maximum crushing strength, or compression strength parallel to grain, is high. Some familiar species with high crushing strength parallel to grain include Hard maple, Teak, and White oak. Hardness is rated as medium. It resists denting and marring about as well as white oak or birch. The weight is high. The wood has high density.
