Has many uses: timber used locally for construction, natural dye; important medical plant - bark extracts are used to treat fevers. Mbororo (Oroko), unjeh (Durop).
Animal-dispersed
primary, secondary and degraded rain forest, mostly in the understorey, on steep slopes to level land and swamps, at 50-650 m altitude
Evergreen and semideciduous forests
Evergreen and semi-deciduous forests of Lower Guinea and the Congo Basin, occurring in southern Nigeria to western Democratic Republic of the Congo and Cabinda
Timber used locally for construction under the commercial name "moambe". Also used as natural dye; important medicinal plant, bark extracts used to treat fevers
