The wood is a source of the timber 'Mersawa'[
]. We do not have any more specific information on this species, but the general description of mersawa is as follows:-
The heartwood is orange-yellow, darkening to golden brown with whitish resin veins present; it is not clearly demarcated from the 5 - 8cm wide band of sapwood. The texture is coarse; the grain straight or interlocked. The wood is of light to moderate weight; it can be soft to fairly hard; somewhat durable being fairly resistant to termites but susceptible to fungi and dry wood borers. It seasons slowly with only a slight risk of distortion or checking; once dry it is moderately stable to stable in service. The wood contains silica and has a high blunting effect - stellite-tipped and tungsten carbide tools are recommended; there is a tendency to tearing on quartersawn timber; nailing and screwing are good; gluing is correct. The wood has a range of uses including flooring, boxes and crates, interior panelling and joinery, turnery, veneer[
