Priority Two — Poorly Known Taxa (DEC)
The erect bushy pungent shrub typically grows to a height of 0.7 to 1.5 metres (2 to 5 ft) and has an obconic habit. It has smooth, light-grey coloured bark and slightly ribbed and sparsely haired branchlets. Like most species of Acacia it has phyllodes rather than true leaves. The evergreen ascending to erect phyllodes have a narrowly oblanceolate to elliptic-oblanceolate shape and can be straight to slightly curved. The rigid and glabrous phyllodes have a length of 1.5 to 2.5 cm (0.59 to 0.98 in) and a width of 2.5 to 4 mm (0.098 to 0.157 in) with a pungent apex with many parallel and raised nerves. It blooms from August to September and produces yellow flowers.
It has a limited distribution from around Salmon Gums and Grass Patch in the east and around Peak Charles National Park and around Dunn Swamp where it is found on flats and plains growing in sandy clay to loamy soils as a part of low woodland and open shrubland communities.
