To follow B. zanzibarensis, Vatke & Pax, from which it may be distinguished by 
its narrower cuspidate-acuminate leaves, which are cuneate at the base, and have

branchlets spreading, angular, pubescent or at length nearly glabrous. 
Leaves oblong or oblong-elliptic, caudate-acuminate, acumen about

Lower Guinea. Gaboon: around Libreville, K/aine, 3422! 3432! 
Very similar to C. bipindensis, Pax, from which it can scarcely be separated 
except by dissection and comparison of the flowers. It differs in its subsessile 
flowers, smaller and thinner male and female disks, more numerous stamens, and 
larger subsessile anthers.
