[1] The spreading shrub or tree typically grows to a height of 1 to 6 metres (3 to 20 ft) and has smooth bark with terete branchlets.

The glabrous leaves are 2 to 6.5 cm (0.79 to 2.56 in) in length and have one prominent gland near the middle of the lowermost pair of pinnae.

After flowering leathery straight to curved, flat seed pods form with a length of 4 to 14 cm (1.6 to 5.5 in) and a width of 6 to 12 mm (0.24 to 0.47 in).

[1] The type specimen was collected by the botanist Alan Cunningham in 1827 on the Liverpool Plains of New South Wales.

It is often a part of dry sclerophyll forest and woodland communities and grows in sandy and skeletal soils over and around granite.
