A medium-to-large tree of the legume family (APG classification: Fabaceae), 6-10 meters tall. It grows wild in the dry grasslands of Arabia and Africa. Gum arabic is made by cutting the trunk of this species, secreting a yellow translucent sap that hardens and is then refined. It is mainly produced in Sudan and Senegal, and is harvested from December to June of the following year. A similar substance can be obtained from several other species of acacia, including this species, Vachellia nilotica (L.) PJHHurter et Mabb. ( A. arabica Willd.) and A. laeta R.Br.
