Description EDIT
This tree is found on the edges of rivers and streams, and may be found further from permanent water, in higher rainfall areas.

It is the most conspicuously upright, often very large thorn-tree, next to rivers, and has exceptionally dense, dark green, feathery foliage. Trees reach a height of 25 m, with very dense foliage. Branches stay thick, even towards their extremities, giving the a robust appearance. It has conspicuous, often dark, cushion-like thickenings, at the base of new thorns and where the leaves come out. Leaflets tend to look half- closed. The flower-balls are white and can be seen early in spring. The pods are slender and slightly sickle-shaped and hang from the trees in bunches. The bark is dark grey to dark brown and closely grooved lengthways. Stipules spinescent. the spines usually small, from 7 - 20 mm,straight, greyish in colour and sometimes semi-inflated.
