Description

A tough, resistant greenheart timber (Cyclicodiscus gaburensis ) often used by shipbuilders and for dock timbers. Also known as okan and dahoma, the dark, green trees can range in height from 5m to 50 m depending on available moisture. The African greenheart is being exported in increasing quantities to Europe and other destinations. The plant is also a popular traditional medicine, a source of fiber and a soap substitute. It is sometimes employed as a shade tree in plantations, often by being left as the forest around it is cleared.
