Element of the Upper Guinean Domain and Lower Guinean Domain of the Guineo-Congolian Region: Cameroon, Gabon, Ghana, Ivory Coast, Nigeria. Habitat and ecology. Lowland mature or old secondary rain forests, near streams. Altitude: 30-140 m a.s.l. Phenology. Flowers collected from December to May. Fruits collected from March to May, from July to August, and in November. Vernacular names. Cameroon: 'Ebom Bulu' (Parren 223) or 'Ebom Afame' (Parren 68) in Bulu/Ewondo. Notes. This species is close to Uvariodendron connivens and Ud. fuscum var. giganteum by having large obovate leaves (more than 25 cm long). However, it can easily be distinguished from these three other species as it presents a tomentum of short dense brown matted hairs on the young parts (branches, petioles and lower midrib), producing a brown appearance with whitish reflections. The flower buds and outer petals are also covered outside with a similar brown and dense tomentum. The older parts of the plant are generally glabrous but can also present remnants of the tomentum.

The inset shows the extent of the map over Africa. Conservation status. This species is widespread, distributed from Ivory Coast to Gabon. It has been previously assessed as Least Concern LC ( Cosiaux et al. 2019a ). Additional specimens examined. Cameroon - Central Region • J.N.
