| Evergreen, dioecious medium-sized tree up to 30 m tall; bole often branched low; bark brownish grey to pale green, smooth; branchlets first stellate-pubescent but soon glabrous. Leaves alternate, simple and entire; stipules c. 3 mm long, caducous; petiole up to 6.5 cm long, slightly swollen at base and apex; blade narrowly obovate to elliptical, up to 13(–23) cm × 6(–10) cm, base cuneate, apex obtuse to obtusely acuminate, leathery, glabrous, pinnately veined with c. 10 pairs of lateral veins. Inflorescence an axillary fascicle on 1–3-year-old branches. Flowers unisexual, regular; pedicel 5–10 mm long, pubescent; calyx stellate-pubescent; petals absent. Fruit consisting of 1–3 club-shaped follicles c. 2 cm × 1 cm, narrowing into a stalk-like base, stellate-pubescent, 1-seeded. Seed oblong-ellipsoid, c. 2 cm × 1.5 cm, shiny brown. Cola comprises about 100 species and is restricted to continental Africa. Some other Cola spp. are used as a source of wood in East Africa. Cola discoglypremnophylla Brenan & A.P.D.Jones is a small tree up to 10 m tall occurring in riverine and lowland forest in Tanzania and perhaps Mozambique; its wood is used for poles, tool handles, animal traps and firewood, and it is also a shade tree. The wood of Cola uloloma Brenan, occurring in lowland forest in Kenya, Tanzania and Malawi, is used for poles, tool handles, firewood and charcoal production; this species is also used as a shade tree. Cola usambarensis Engl. is a small tree up to 15 m tall occurring in submontane forest in Tanzania. Its wood is hard, heavy and tough, and is used for poles, animal traps, tool handles, firewood and charcoal production; rope and medicines are also obtained from the tree. Low-altitude populations of Cola usambarensis have sometimes been confounded with Cola lukei Cheek, a tree from eastern Tanzania, up to 10 m tall and sometimes coppiced for poles. Cola lukei is classified as endangered in the IUCN Red list of threatened species, due to habitat loss and growing local population pressure. | |||

| Cola clavata is classified as data deficient in the IUCN red list of threatened species, indicating that there is inadequate information to assess its risk of extinction. | |||
| show more data (0) | comments (0) |
| Although the wood of Cola clavata is considered to have favourable properties, too little information on the wood properties is available to properly evaluate its prospects for increased use as a source of timber. | |||
