Acacia cummingiana

Acacia cummingiana is a sprawling, straggly, rush-like shrub or subshrub, that typically grows to a height of 30–50 cm (12–20 in) and has terete, striated branches. Its phyllodes are reduced to continuous, thin, horizontally flattened, narrowly oblong to narrowly triangular scaled 1.5–4 mm (0.059–0.157 in) long. The flowers are borne in spherical heads in one or two scale axils, on a peduncle 4–15 mm (0.16–0.59 in) long. Each head is about 8 mm (0.31 in) in diameter when dry, and has 8 to 12 loosely arranged, bright light golden flowers. Flowering occurs from May to June, sometimes to August, and the pods are stalked, 40–70 mm (1.6–2.8 in) long and 8–10 mm (0.31–0.39 in) wide, shallowly curved and leathery to crusty. The seeds are oblong to elliptic, about 5.5 mm (0.22 in) long with a conical aril on the end.

This species of wattle is restricted to a small area between Watheroo National Park and Wannamal where it grows in sand or gravel in heath or low woodland in the Avon Wheatbelt, Geraldton Sandplains and Swan Coastal Plain bioregions of south-western Western Australia.
