Berlinia bisulcata (A.Chev.) Troupin
Common Name: Zingana
Zingana is a large tree that can grow up to 40 metres tall. The straight, cylindrical bole can be free of branches for up to 20 metres, and 60 - 100cm in diameter[
The tree is exploited commercially from the wild for its valuable timber[
Large-scale habitat decline (caused by clearance for agriculture), coupled with exploitation of the tree for timber, have caused population declines and the tree is listed as 'Critically Endangered' in the IUCN Red List of Threatened Species(2009)[
Western tropical Africa - Cameroon.

The heartwood is a yellow-brown to light brown, with dark brown veins; it is clearly demarcated from the 6 - 10cm wide band of sapwood. The texture is coarse; the grain interlocked, sometimes highly interlocked. The wood is moderately heavy to heavy; moderately hard; moderately durable, being resistant to dry wood borers and moderately resistant to fungi and termites. It seasons slowly, with a high risk of checking and distortion; once dry it is moderately stable in service. The wood works well with ordinary sawteeth, but there is a risk of tearing due to the highly interlocked grain - tungsten carbide cutting tools are recommended; nailing and screwing are good, but require pre-boring; gluing is correct. A valuable timber species, often with dark and light streaks, it is used in turnery, high class furniture and cabinet making as well as for tool handles, wood-ware, interior panelling and veneer[
