About
Drypetes gerrardii is a species of small tree or large shrub in the family Putranjivaceae. Common names include forest ironplum, bastard white ironwood, and forest ironwood. It is native to tropical and subtropical central and eastern Africa. It was first described in 1920 by the English botanist John Hutchinson, who named it after the English botanist William Tyrer Gerrard who collected plants and seeds in southern Africa in the 1860s.
Where it grows
This tree is native to Central and Eastern Africa, where its range extends from South Sudan, Uganda and Kenya, southwards to Angola, eastern South Africa and Eswatini. In South Africa it is found in the Eastern Cape, KwaZulu-Natal, Limpopo and Mpumalanga provinces. It grows in drier evergreen forests, in riverine corridor forests, and sometimes in wetter rain forests, as well as in scrubby habitats, at altitudes between 600 and 2,300 m (2,000 and 7,500 ft).
Uses
As a small tree, the timber of Drypetes gerrardii is not traded but is used locally for poles, tool handles, furniture, utensils and pestles. It is also used as firewood and for making charcoal. The flowers are nectar-rich and attract honeybees and the fruit is edible. The tree has limited use in traditional medicine, a decoction prepared from the roots being used for abdominal pain and powdered leaves and roots being used to treat gonorrhea. The tree is sometimes grown to provide shade.
