The divaricate, spreading and prickly shrub typically grows to a height of 0.5 to 1 metre (2 to 3 ft). It blooms from June to October and produces yellow flowers.[2] The shrub has slender, spinescent, pruinose branchlets. The majority of older phyllodes are shed giving it an open twiggy appearance. The thick phyllodes have an oblong-elliptic shape with a length of 2 cm (0.79 in) and a width of 2 mm (0.079 in) have three to five obscure longitudinal veins. The simple and axillary inflorescences occur is pairs or solitary with spherical yellow flower-heads.
