Confined to the drier eastern, southern and western parts of Zambia and the shores of the northern lakes, but widely scattered. Often on termite mounds, riverine forest and on sandier soils, but occasionally in Mopane woodland.
Size: Height up to 18m, spread 8 to 12m.
Bark: Dark grey, or black with vertical fissures (sometimes twisted) and irregularly sized scales.
Leaves: Simple, alternate, leathery, elliptic to oblong-elliptic, 5 to 11cm, shiny green above, paler below and sometimes hairy on the obvious herring-bone veins, tapering to the apex base rounded. Petiole 1 to 1.5cm.
