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 hereroensis is a South African indigenous species from the Free State, Gauteng, Limpopo, Northern Cape and North West Provinces. It is commonly known as Arid Hook-thorn, Mountain Thorn or Coffee Mimosa in Afrikaans and Bergdoring, Bergdoringboom, Dorre-haakdoring, Haak-en-steek, Haak-en-steekdoring or Rooihaak in English and is synonymously known as Acacia gansbergensis and Acacia mellei. It grows into a beautiful tree of up to 10 meters tall. It has dark bark and small leaflets. During summer it bears creamy-white flowers in short spikes which are followed by reddish velvety pods.
