About

Sideroxylon inerme (aMasethole or white milkwood, Afrikaans: wit-melkhout, Xhosa: Ximafana, Zulu: Umakhwelafingqane) is a southern and eastern African coastal tree, with dense foliage, black berries and small, foetid, greenish flowers. The tree's generic name means "Iron-wood" in Greek, referring to its very hard timber.

It is one of South Africa's "Protected Trees" and several specimens are provincial heritage sites. This is the only member of the genus Sideroxylon in Southern Africa.

Where it grows

Sideroxylon inerme trees are scattered through the coastal woodlands and littoral forests of southern and eastern Africa, from the Cape Provinces of South Africa in the south to Somalia in the north, and on Aldabra, the Comoro Islands, and the Mozambique Channel Islands in the western Indian Ocean. Historically, dense forests of large milkwood trees used to exist along the coast and bays of Cape Town, especially at Noordhoek, Macassar and Gordons Bay.
