Compact, rounded shrub to 3 m high, or tree to 6 m. Branchlets normally appressed-puberulous. New shoots pale yellow (at least when dry), ageing silvery due to indumentum. Phyllodes narrowly elliptic to narrowly oblong, 2-4.5 cm long, 4-10 mm wide, l:w = 4-7, obtuse, ±thin, smooth, grey-green to glaucous, finely appressed-puberulous, 1-nerved; midrib and marginal nerves prominent; lateral nerves often obscure; gland 1-5 mm above pulvinus, and rarely also at base of mucro. Inflorescences 2-4-headed racemes; raceme axes 5-20 mm long, puberulous, growing out or often the distal peduncles subtended by young phyllodes; peduncles 10-25 (-30) mm long, puberulous; heads globular, subdense, 25-30-flowered, bright golden. Flowers 5-merous; sepals united into a ± truncate calyx. Pods moniliform, 5-10 cm long, 8-13 mm wide, crustaceous, smooth, red to dark brown, sparsely and minutely appressed-puberulous. Seeds longitudinal, spherical, compressed, 7-8 mm long, dull, brown; aril hemispherical, dark red (dry).
More
A medium shrub growing 3-5 m high and spreading 2-4 m across. The branches are nearly round in cross section and covered with many soft hairs. The leaves (phyllodes) are 2.5 cm long by 1 cm wide. They are oblong and narrowed at the base. They end with a small hooked point. They have an ash grey appearance because of fine silky hairs. There is one vein along the leaf and the edges of the leaf are thickened. The flower heads are pale yellow balls. The flower stalk is about as long as the leaves. The pods are long and 0.6 cm wide. They are hard, woody and straight. They are very constricted between the seeds.
