The shrub has a spreading habit and typically grows to a height of 3 m (9.8 ft) and a width of 4 m (13 ft). The large grey-green phyllodes have an ovate-lanceolate shape with a length of 10 to 25 cm (3.9 to 9.8 in) and a width of 2 to 9 cm (0.79 to 3.54 in) and are covered with white silky hairs, with three to four prominent veins. The flowers are rod-like and bright yellow, 3–5 cm long. The thinly crustaceous seed pods that form after flowering are tightly irregularly coiled and have a width of 2.5 to 4 mm (0.098 to 0.157 in). The pods are 3 to 5 cm (1.2 to 2.0 in) in length and twisted and curled. The shiny dark brown seeds are arranged longitudinally in the pods and have an obloid-ellipsoid shape and are 3 to 5 mm (0.12 to 0.20 in) in length with a bright yellow aril. The seed is edible.
