Phyllodes narrow-obovate, oblanceolate, 3-6 cm long, 4-10 mm broad, straight or slightly curved, glabrous, light-green, mid-vein slightly eccentric, lateral veins numerous obscure and reticulate, margins prominent and yellowish, apex obtuse and with or without a short mucro; glands small situated on the upper margin below the centre of the phyllode,

Inflorescences axillary glabrous racemes, normally c. half as long as the phyllodes, rarely almost as long as phyllodes, raceme axis slender, glabrous and normally with 5-8 heads; flower-heads globular, yellow 15-20-flowered; peduncles slender, glabrous, 3-5 mm long; flowers 5-merous.

Legumes linear, 6-12 cm long, 6-7 mm broad, coriaceous, flat but raised over seeds, narrowed at both ends, short-stipitate; margins thickened and vein-like, slightly contracted between seeds.
