Pericopsis angolensis laxiflora (Benth.) Yakovlev
Pericopsis laxiflora is a deciduous shrub or tree with a dishevelled crown of crooked, drooping branches; it usually grows from 9 - 13 metres tall, but is occasionally only a shrub up to 2 metres. The bole is usually twisted and crooked, up to 25cm in diameter[
The tree is a popular traditional medicine and is commonly harvested from the wild for local use. It also provides a very good quality timber, but generally only in small dimensions and so is not suitable for commercial exploitation[
Tropical Africa - Senegal to Sudan.
Savannah woodland, often in rocky places, on ironstone and lateritic soils in high rainfall areas; fringing forest. One of the commonest trees[

The wood is very similar to Pericopsis angolensis, and can be used for the same purposes, but larger sizes are not available[
]. The description and uses of the wood of Pericopsis angolensis are as follows:-
The heartwood is greenish brown, turning dark brown to almost black upon drying; it is distinctly demarcated from the up to 25mm wide band of whitish to yellowish grey sapwood. The grain is interlocked; texture moderately fine; the wood is strikingly banded or shows a whorled figure; it is oily to the touch. The wood is heavy, very hard, very durable and resistant to fungi, termites and all wood borers including marine borers. It is also highly resistant to abrasive action and chemicals. It air dries very slowly but with little degrade, except slight surface checking. The rates of shrinkage are low; once dry it is moderately stable in service. The wood is difficult to saw and work because of its high density; it is rather difficult to plane and a cutting angle of 20% is recommended, but it has a smooth finish; it holds nails and screws well, but pre-boring is necessary; gluing, staining and polishing do not cause problems. The wood turns well; bending properties are moderate. Traditionally, the extremely durable wood is highly esteemed for making hoes and pestles, and for the rims and hubs of wagon wheels. Commercially, if pieces sufficiently large are available, the wood is used for flooring and panelling, and it is also suitable for heavy construction, railway sleepers, mine props, ship building, vehicle bodies, fence poles, vats, interior trim, joinery, furniture, cabinet work, handles, ladders, agricultural implements, sporting goods, musical instruments, toys, novelties, precision equipment, carvings and turnery[
The wood is used as a fuel - it is difficult to light, but produces great heat and little ash. It also makes excellent charcoal[
