Combretum, the bushwillows, is a genus of about 272 mostly tropical and southern African trees and shrubs, named for the willow-like habit of some species. Most grow in warm, sunny, well-drained conditions, and many are large savannah trees rather than houseplants.

About
Combretum, the bushwillows or combretums, make up the type genus of the family Combretaceae. The genus comprises about 272 species of trees and shrubs, most of which are native to tropical and southern Africa, about 5 to Madagascar, but there are others that are native to tropical Asia, New Guinea and the Bismarck Archipelago, Australia, and tropical America.
Around 17 species in the genus Quisqualis are very similar to Combretum and are now classified as species of the genus.
Where it grows
Bushwillow trees often are important plants in their habitat. Savannahs in Africa, in particular those growing on granitic soils, are often dominated by Combretum and its close relative Terminalia. For example, C. apiculatum is a notable tree in the Angolan mopane woodlands ecoregion in the Kunene River basin in southern Africa.
Uses
Several species are used in African or Indian herbal medicine. Several species of this genus in Madagascar known collectively as voantamenaka or voatamenaka (from voa 'fruit' and menaka 'oil') are used in traditional Malagasy medicine as deworming remedies. The class of chemical compounds known as combretastatins were first isolated from South African bushwillow (Combretum afrum), from which they get their name. One synthetic derivative, fosbretabulin disodium (combretastatin A4 phosphate), underwent preliminary study for the treatment of anaplastic thyroid cancer, but it was not effective enough to progress to more advanced trials. C. molle is also recorded to contain antioxidants such as punicalagin, which is also found in pomegranates (Punica granatum), a somewhat related plant.
