This wood is fine grained and durable, with an attractive lustre -excellent for furniture ! The tree's timber is also used for mining and construction work.  Mpasa is medium-heavy and hard.  The sapwood is buff-brown and the heartwood brown.  The texture is fine, works easily and produces a smooth surface.  It is termite resistant and quite suitable for manufacturing of furniture.

It is also known as a good 'bee tree' with the honey made from its nectar being of a very high quality.


Mpasa  Leaves

   
The leaves are simple and are arranged symetrically and alternately on young twigs.  Their size varies enormously and they are rough in texture and oblong.  Their upper surface is dark green and glossy, smooth and marginally entire.  They eventually turn bright red to reddish-brown.

Flowers occur in small groups in leaf axils.  Their positioning is sessile (no support such as a stalk) and they are very small, pale to yellow-green and different sexes occur on different trees.  Flower buds appear in autumn and open in October/November.

Edible fruits occur in clusters, are ovoid and approx. 1cm x 0.7cm. in size.  Their mesocarp is relatively thick, their skin smooth and pitch-black when ripe in January/February.

The roots are crushed and used for treating stomach aches, tapeworms, diarrhea, headaches, and sore joints. The leaf sap is used for sore eyes.

The fruits are sweet, tasting like currants and are readily eaten by children.
