Acacia nilotica
Acacia nilotica (Thorn mimosa) is a species of Acacia (wattle) native to Africa and the Indian subcontinent. It is also currently an invasive species of significant concern in Australia. For the ongoing reclassification of this and other species historically classified under genus Acacia, see the list of Acacia species. Additional recommended knowledge
DescriptionAcacia nilotica is a tree 5-20 m high with a dense spheric crown, stems and branches usually dark to black coloured, fissured bark, grey-pinkish slash, exuding a reddish low quality gum. The tree has thin, straight, light, grey spines in axillary pairs, usually in 3 to 12 pairs, 5 to 7.5 cm long in young trees, mature trees commonly without thorns. The leaves are bipinnate, with 3-6 pairs of pinnulae and 10-30 pairs of leaflets each, tomentose, rachis with a gland at the bottom of the last pair of pinnulae. Flowers in globulous heads 1.2-1.5 cm in diameter of a bright golden-yellow color, set up either axillary or whorly on peduncles 2-3 cm long located at the end of the branches. Pods are strongly constricted, hairy, white-grey, thick and softly tomentose. Its seeds number approximately 8000/kg.[2] DistributionScented Thorn Acacia is native from Egypt south to Mozambique and Natal. Apparently, it has been introduced to Zanzibar, Pemba, India and Arabia. Acacia nilotica is restricted to riverine habitats and seasonally flooded areas. UsesForage and fodderIn part of its range smallstock consume the pods and leaves, but elsewhere it is also very popular with cattle. Pods are used as a supplement to poultry rations in India. Dried pods are particularly sought out by animals on rangelands. In India branches are commonly lopped for fodder. Pods are best fed dry as a supplement, not as a green fodder. HedgesA. nilotica makes a good protective hedge because of its thorns.[3] MedicineBarkAccording to Hartwell, African Zulu take bark for cough. It acts as an astringent and it is used to treat diarrhea, dysentery, and leprosy. Bark and rootMasai are intoxicated by the bark and root decoction, said to impart courage, even aphrodisia, and the root is said to cure impotence. Bark or gumIn West Africa, the bark or gum is used to treat cancers and/or tumors (of ear, eye, or testicles) and indurations of liver and spleen, condylomas, and excess flesh. Sap or bark, leaves, and young pods are strongly astringent due to tannin, and are chewed in Senegal as an antiscorbutic. LeavesThe bruised leaves are poulticed and used to treat ulcers. ResinIn Lebanon, the resin is mixed with orange-flower infusion for typhoid convalescence. RootThe Chipi use the root for tuberculosis. In Tonga, the root is used to treat tuberculosis. Seed podsEgyptian Nubians believe that diabetics may eat unlimited carbohydrates as long as they also consume powdered pods. WoodIn Italian Africa, the wood is used to treat smallpox. In Ethiopia, certain parts of the tree are used as a lactogogue. WoodThe tree's wood is "very durable if water-seasoned" and its uses include tool handles and lumber for boats.[3] The wood has a density of about 1170 kg/m³.[4] PropagationThere are 5000-16000 seeds/kg.[5] Subspecies
