== Origin and geographic distribution ==
The wood of ''Cola clavata'' is heavy, hard, tough and termite-resistant.
== Botany Description ==
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.== Other botanical information ==
