The wood is yellowish white to greyish yellow. The grain is straight, texture coarse. The wood is soft and moderately light in weight. The veneering properties are satisfactory. The wood is not durable, but fairly easy to impregnate with preservatives. The wood is used for posts, carpentry, shuttering, fences and veneer. It is suitable for light joinery, interior trim, furniture, boxes and crates. The boles are used to make dug-out canoes[

Propagation

Seed - it has a hard seedcoat and, unless sown when fresh and still moist, may benefit from scarification before sowing to speed up germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing. When seedlings are raised in the nursery, they can be planted into the field after 6 - 12 months when they are 50 - 100cm tall[

The fruits are collected from the tree or the ground when they have become dry and blackish. The seeds are extracted manually and non-viable seeds are separated by floating in water. Viable seeds are dried in the sun. The seeds can be stored for up to 4 years and still achieve a germination rate of 50 - 70%[
