    The species as here accepted is widespread and includes a number of smaller geographical segregates. Characters such as degree of laciniation and number of segments of staminodes, and minor differences in leaf-size, which previously have been used to distinguish species, have proved impossible to work within the range of material now available. The tree yields a useful timber, known as Nkunya in Uganda, which is very hard and durable in the ground (see Uganda For. Dept. Timber Leaflet No. 3). A single sterile gathering from the E. Usambara Mts. may possibly extend the species range into E. Tanganyika (see under imperfectly known species No. 1, page 73).
