Distribution. A widespread species with a disjunct distribution in West and Central Africa, from Côte d’Ivoire to Ghana, and from Nigeria to Cameroon. In Cameroon known from the South, Central, Littoral, South-West and North-West regions. Habitat. A fairly common species; in lowland primary or old secondary rain forests, near streams. Altitude 50-30 m a.s.l. Local and common names known in Cameroon. None recorded. IUCN conservation status. Least Concern (LC) (Cosiaux et al. 2019a f). Uses in Cameroon. None reported. Notes. <i>Uvariodendron calophyllum</i> is distinguished by a dense brown tomentose pubescence on the young foliate branches, petioles, flowering pedicels, and outer side of the sepals and petals. Uvariodendron fuscum var. giganteum also has a dense pubescence on the young foliate branches, but the hairs are long and white, and soon disappearing with age. Stamen count was taken from Meinke (2008).
