The slightly angular and hoary branchlets have resinous ridges[3] and smooth grey bark.

The glabrous, thinly leathery and evergreen phyllodes have an obovate to oblanceolate shape with a length of 3 to 7 cm (1.2 to 2.8 in) and a width of 4 to 11 mm (0.16 to 0.43 in) and are straight to shallowly curved with three resinous and distinct main veins that are impressed in crests of low ridges and surrounded by many secondary veins.

[3] The species was first formally described by the botanist Ferdinand von Mueller in 1863 as a part of the work Fragmenta Phytographiae Australiae.

[1] It is thought to be quite closely related to Acacia redolens, a species found in Western Australia.

In New South Wales the range of the plant is mainly between West Wyalong, Condobolin and Forbes where it is usually found growing in red earth soils as a part of mallee communities.
