Senegalia is a genus of flowering plants in the family Fabaceae. It belongs to the Mimosoid clade. Until 2005, its species were considered members of Acacia. The genus was considered polyphyletic and required further division with the genera Parasenegalia and Pseudosenegalia accepted soon after. Senegalia can be distinguished from other acacias by its spicate inflorescences and non-spinescent stipules. Plants in the genus are native to the tropical and subtropical areas of the world, occurring on the Australian, Asian, African and South and North American continents, as well as in Wallacea.

Senegalia afra (Previously known as Acacia caffra, then renamed to Senegalia caffra, and recently renamed to the more appropriate Senegalia afra) makes a beautiful bonsai and is fast growing. Wow, what an elegant tree to have! One of the most attractive features of Senegalia afra is the foliage which is bright green and feathery looking. The leaves have a drooping nature which gives the canopy a lovely soft look. The species name, afra, was an epiphet frequently bestowed on plants from the eastern parts of South Africa in previous centuries.
