A moderately fast growing, spreading shrub, 2 - 5 m tall. Grows in hot, semi - arid parts of the tropics and subtropics, altitude 10 - 525 m, rainfall 125 - 600 mm, on a diverse range of soils, particularly infertile soils. It has low palatability to stock and moderate nutritive value, but good potential for fuel and soil stabilisation on infertile sands and lithosols.
