About

Drypetes arguta, commonly known as the water ironplum, is a species of small tree or large bush in the family Putranjivaceae. It is native to tropical East Africa. It was first described in 1920 by the English botanist John Hutchinson, who named it Cyclostemon argutus. It was later transferred to the genus Drypetes.

Where it grows

Drypetes arguta is native to eastern Africa where its range extends from Tanzania and Zimbabwe, southwards to Mozambique, Eswatini, and South Africa (KwaZulu-Natal). It grows in forests and alongside water-courses, at elevations of up to 600 m (2,000 ft). It is also a major constituent of the flora of the Southern African Sand Forest, a habitat consisting of woodland growing on ancient sand dunes located on the border between southern Mozambique and northern KwaZulu-Natal.

Uses

Sections of branches of this tree have traditionally been used in hut construction, and the wood has also been used to make sticks. The fruits are edible and have been used to make a fermented alcoholic drink.
