Mundulea sericea, the cork bush, is an attractive shrub or small tree which is found in relatively open woodlands of Africa and South Asia.

The species occurs commonly in Madagascar, southern to central Africa, India and Sri Lanka.

[3] At its southern limit it is found in northern KwaZulu-Natal and northwards of the Vaal River, South Africa.

These hairs turn grey with time, and the pods may remain on the tree up to the next flowering season, or longer.

The bark of the stem and main branches is deeply grooved and corky, and contains the poison rotenone.
