In Stoffelen 1998: bush or shrub (1-2-4 m), Leaves acuminated, coriaceous, with extra-axillary pubescent domatia; would be a rheophytic species of the Congo Basin. Typical of the arborescent formation of running water and the temporary inundated forest (up to 3 months). In ex situ collection, it flowers abundantly at 3 years old and become sterile 2 years later. Need grafting on other species for long-term ex situ conservation. The distribution of the diaspores mediated by water and by birds, the fruit are ripe during the period of inundation. In Berthaud 1986, variable species, rather similar in appearance to C. arabica. Within each natural population there is a considerable amount of phenotypic variation. Fruits smooth pedunculate. |
