Diagnostic
A large spreading tree, differing from C. schweinfurthii in its fewer leaflets, with ± 9 pairs of principal lateral veins on longer petiolules, and in its much smaller flowers in spreading panicles ± as broad as they are long. The stone of the fruit has less sharp angles than that of C. schweinfurthii and has 3 minor ridges between each of the angles instead of one only as illustrated by Kabuye in Utafiti 1(2), fig. 1/9 (1988), Fig. 1/9, p.3.
Habitat
Rare in forest remnants on sandy soil in shallow river valleys; 5–300 m.; rainfall ± 1000 mm.
Distribution
