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 galpinii, previously known as Acacia galpinii and commonly known as Monkey-thorn or Apiesdoring, is a large tree with luxuriant, light green foliage, making it ideal for a big garden, avenue or park. It is also valued by farmers. Senegalia galpinii is a deciduous tree, losing its leaves during the southern African winter (April-July). It is fast-growing and can reach 25-30 m. Creamy to light yellow flowers appear during the growing season (September-October). Reddish to purplish brown pods ripen during February-March. Monkey-thorn grows naturally in open, wooded grassland, open woodland and often near streams. It is indigenous to Zambia, Zimbabwe, Malawi, northern and eastern Botswana and South Africa. In South Africa, Senegalia galpinii occurs naturally in Limpopo [Northern Province] and the North-West. It is seen as an indicator of sweet veld, which retains its nutritional value in winter. Senegalia galpinii is one of the trees that can survive hot and dry conditions. It makes a stunning tree along roads where there is enough space. It is an ideal tree for a big garden but is also very well suited to the art of bonsai. In the wild the plant is grazed and used for shade during the hot summer by different animals including giraffe, kudu and elephant. Many birds often prefer nesting in this tree as it provides protection. It provides dappled shade on hot summer days, making it an ideal tree for planting on a lawn where some sun can penetrate.
