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.
