Sparsely occurring from eastern Nigeria to the Democratic Republic of the Congo; in Cameroon known from two collections in the South and Central regions. Habitat. A rare and little known species; in primary rain forest and semi-deciduous forests. Altitude 20-200 m a.s.l. Local and common names known in Cameroon. None recorded. IUCN conservation status. Least Concern (LC) (Cosiaux et al. 2019b d). Uses in Cameroon. <i>Materials</i>: wood for weapons, tools (Tessmann 1913). Notes. <i>Xylopia pynaertii</i> is distinguished by the scaly bright reddish brown upper bark, the long dense hairs of the young branches and lower leaf surfaces, the relatively small leaves (3.6-8.7 cm long), and the short wide monocarps with seeds in two rows.
