Protorhus ditimena H.Perrier
Abrahamia ditimena is an evergreen tree that can grow up to 25 metres tall. The bole is up to 35cm in diameter[
The tree is harvested from the wild for local use as a medicine and source of wood.
Abrahamia ditimena is quite widespread, but it occurs scattered in the forest and is limited to threatened types of forest. Therefore, caution is needed in harvesting this species to prevent genetic erosion[

The tree grows slowly[
A dioecious species, both male and female forms need to be grown if fruit and seed are required[
The leaves are used in traditional medicine as sedative[
Abrahamia ditimena, and other Abrahamia species, have been recommended for enrichment planting in natural forest, and as non-pioneer light-demanders that also tolerate some shade they are suited for that purpose. However, they grow slowly and long cutting cycles are needed for timber production, and therefore commercial exploitation on a sustainable basis seems to have little prospects
The heartwood is chestnut brown and streaked; it is distinctly demarcated from the up to 6cm wide band of paler sapwood. The grain is generally straight, texture fine. The wood is moderately heavy, moderately durable, with fair resistance to termites, but it is rather susceptible to fungal attacks. It air dries easily with little checking and warping; rates of shrinkage during drying are medium. The wood works easily, glues satisfactorily and the nailing properties are moderate. The wood is used for construction, joinery, flooring, panelling, moulding and railway sleepers[
]. For usage as railway sleepers, it is advised to treat the wood with preservatives under pressure[
