We do not have any more information on the wood of this species, but the following is a general description for the wood of this genus:-
The heartwood is variable, light pinkish cinnamon, dull oatmeal, medium to dark brown, sometimes reddish or purplish; it is often not very clearly demarcated from the wide band of oatmeal-coloured sapwood. The texture is medium; the grain mostly straight; lustre is medium to fairly high; without distinctive odour or taste. The wood can be air-dried with little or only moderate difficulty; slight to moderate checking and warp may develop. All of the species in this genus have very good machining properties and produce smooth surfaces on the normally straight-grained material. The wood is easily peeled for veneer. It is used for purposes such as millwork, turnery, furniture, boxes and crates, veneer and plywood, general construction, fiberboard, and particleboard[
