"Single-stemmed, umbrella-shaped tree to 15 m high, sometimes a shrub. Bark almost stringy, dark grey to black." (WorldWideWattle ver. 2)

"Grows often in dense stands, also in closed forests, low open forests or mixed savannah woodlands, in shallow gravelly or skeletal sandy soils on sandstone or laterite. Flowers mostly early Mar.–late May in N.T., late Apr.–mid-July in Qld." (WorldWideWattle ver. 2)

In many instances close colonisation of poor, elevated substrates infer the need for substantial rain before seed crops may appear on this Acacia species. There may be exceptions such as in disturbed country.
