The tree typically grows to a maximum height of 10 m (33 ft) and has a slender with a whitish-greyish coating. It has ribbony or flaky bark that is a red-brown to brownish colour. The angular red-brown or brown coloured glabrous branchlets become flattened towards the apex and have a white powdery coating. Like most species of Acacia it has phyllodes rather than true leaves. The evergreen grey-green, flat phyllodes usually have very narrowly elliptic shape and are straight to falcate with a length of 6 to 23 cm (2.4 to 9.1 in) and a width of 6 to 32 mm (0.24 to 1.26 in) with three to six prominent main veins that are continuous to the base. It blooms between August and late October producing golden coloured flowers.[2]
