Erect, bushy or slender, glabrous shrubs 1-2 m high, branching into a number of ascending stems at ground level; branchlets and stems smooth reddish-brown, slightly pruinose, almost terete.

Phyllodes linear, almost terete or obtusely quadrangular with a prominent vein at each angle, 9-13 cm long, c. 1 mm broad, erect, brittle, dull-green, apex gland bearing below the small recurved thickened mucro, a second brown depressed gland situated at the base of phyllode just above the wrinkled pulvinus.

Inflorescences in axillary racemes shorter than phyllodes, usually consisting of 5-10 pedunculate heads; flower-heads rather small globular, bright yellow, c. 20-25-flowered; peduncles slender, glabrous, 4-5 cm long; flowers 5-merous.

Legumes oblong, 4-6 cm long, 7-8 mm broad, flat but raised over the seeds, chartaceous, light brown but shiny due to a resinous covering; margins vein-like, slightly constricted. Seeds in legume, almost orbicular, blackish; funicle thin, short, slightly twisted, without an aril.
