The wood is a source of muiracatiara timber. We have no more specific information, but a general description of muiracatiara timber is as follows:-
The heartwood is pinkish-brown to yellow-brown, becoming red-brown to dark brown with very irregularly spaced black-brown veins; it is clearly demarcated from the 4 - 10cm wide band of sapwood. The texture is fine; the grain straight or interlocked. The wood is heavy, hard and very durable, being resistant to fungi, dry wood borers and termites. It seasons normally with little risk of checking or distortion; once dry it is poorly stable in service. It has a fairly high blunting effect upon toold, stellite-tipped and tungsten carbide tools are recommended; nailing and screwing are good, but pre-boring is necessary; gluing is poor. The wood has a wide range of applications, being used in cabinet making for high class furniture, for flooring, turnery, interior and exterior joinery, heavy carpentry, tool handles, musical instruments, carving etc[
