Sideroxylon inerme 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.

Sideroxylon is a genus of trees in the family Sapotaceae described as a genus by Linnaeus in 1753. They are collectively known as bully trees. The generic name is derived from the Greek words σιδηρος (sideros), meaning "iron", and ξύλον (xylon), meaning "wood."
