Gum Arabic tree, Sudan Gum Arabic, Kordofan gum, Three-thorned Acacia (Eng.), Driehaakdoring, Gomdoring, Geelhaak (Afr.)
This small thorny deciduous tree is native to semi-desert regions. It is the source of the world's highest quality gum arabic, known locally as hashab gum. The tree flowers during the rainy season and loses its leaves during the dry season. When water is only available at great depth, deeply penetrating tap roots can develop, and the tree will grow considerably larger than normal. When trees are near well watered locations, they grow taller but they do not produce any gum. The tree has to be under stress, diseased, ill-nourished and cut off from water before it will produce gum. Been used by local people for the preparation of food, in human and veterinary medicine, in crafts, and as a cosmetic. The flowers are a good source of food for bees for the production honey, an important source of nutrition and income generation to support rural livelihoods in marginal lands. South Africa and Australia have policies against further introduction of this noxious weed.
