Acacia is a genus of shrubs and trees belonging to the subfamily Mimosoideae of the family Fabaceae.
This shrub to small tree may reach up to 7 m in height, branching from near ground level and is often wider than high, occurring generally in hot, dry areas, often forming thickets. Its growth form can vary considerably. Over large parts of its distribution range it occurs as a prostrate, spreading, multi–stemmed shrub with dense branches near ground level or with stems rising from branching underground stems. In this form it may be no more than 1 or 2 m high, but can achieve a diameter several times its height. In appearance it is thus often reminiscent of a large, flattened cushion. In some areas it occurs as a more upright shrub or small tree 3 to 8 m high with rounded, spreading crown and drooping branches, also with a considerable horizontal spread. As a low shrub it is found in dry savannah and grassland areas and on soil ranging from Kalahari sands to sandy alluvium soils, often associated with calcrete. As a more upright shrub or tree it is usually found on more moist soils with higher clay content. It is considered to be a good indicator of calcium–rich soils. It is fairly tolerant of cold.
