Widespread, inconspicuous sub-canopy tree with short, thick buttresses when mature. Can be a big tree with deeply fluted bole. Bark grey to purplish dark brown, scaly with rectangular scales leaving reddish mussel-shell markings. Slash pale brown or yellowish, granular or fibrous, not fragrant or only slightly so, exuding slowly a small quantity of white latex turning brown. Very few trees with pinnate leaves have some latex, in Trichilia tessmannii it is yellowish, in Trichoscypha arborea the leaves are clustered. Leaves pinnate, the leaflets mostly alternate or sub-opposite, with many brown spots below. Fruit a globular capsule of 3.5 – 4 cm Ø, glabrous but with pustules, opening with 2 – 3 valves. In a recent revision of the South American genus Guarea it was made credible that the African species of Guarea actually belong to an African genus, Leplaea. Therefore Guarea thompsonii is now a synonym of Leplaea thompsonii. See also PROTA database.
