It has dark reddish brown glabrous branchlets and green narrowly elliptic to oblanceolate shaped pale green phyllodes. The glaucous phyllodes have a length of 2 to 5.5 cm (0.79 to 2.17 in) and a width of 4 to 10 mm (0.16 to 0.39 in) and are acute to acuminate with a slightly excentric midrib and obscure lateral nerves.[1] It flowers between September and November producing[2] racemose inflorescences have spherical flower-heads containing 8 to 15 loosely packed light golden flowers. The firmly chartaceous to thinly coriaceous, glabrous,[1] light brown seed pods[2] that form after flowering have as broadly linear to narrowly oblong shape with a length of up to 13 cm (5.1 in) and a width of 8 to 9 mm (0.31 to 0.35 in) with longitudinally arranged inside. The hard slightly shiny black seeds have an oblong shape with a length of 5 to 6 mm (0.20 to 0.24 in) with a brittle, dark reddish coloured clavate aril.[1]
