Greyia radlkoferi, the woolly bottlebrush or wollerige baakhout in Afrikaans, is a small deciduous tree of up to 5 m. It grows on rocky cliffs and gullies along the escarpment in the north-east of South Africa (SA Tree List No. 445). The branches are smooth and yellowish when young, grey and furrowed later.
The leaves are alternate and round, oval or heart-shaped, clustered at stem tips. They are thick, almost fleshy and sparsely hairy above while densely hairy below. The margins are lobed and toothed.
The flowers are red and bell-shaped with conspicuously protruding red stamens. The flowers grow in densely crowded racemes. Blooming happens late winter and early spring, simultaneously with the appearance of the young leaves (Coates Palgrave, 2002; Schmidt, et al, 2002).
