Distribution. From Cameroon to Gabon; in Cameroon known from South, Central, Littoral and South-West regions. Habitat. A common species when present, in lowland rain forests in primary or secondary habitats. Altitude 50-1000 m a.s.l. Local and common names known in Cameroon. None recorded. IUCN conservation status. Least Concern (LC) (Cosiaux et al. 2019h). Uses in Cameroon. <i>construction</i>: bark for building materials (Tessmann 1913). Notes. Easily distinguished from <i>C. glauca</i> and <i>C. patens</i> by its linear and acute outer petals, in contrast to short and rounded outer petals in the latter two. It is quite hard to distinguish these species based on sterile material alone.
