Shrub or subshrub to 0.5 (-1) m high, rounded, often procumbent, bushy or sparse, glabrous, resinous. Branchlets apically angular but soon terete, with coarse (often minutely resin-crenulated) ridges, finely lenticellate. Phyllodes patent, ±elliptic or ovate (upper margin sometimes slightly more convex than lower margin), often slightly curved and undulate, 0.3-0.6 (-0.9) cm long, 1.5-3 (-4) mm wide, coriaceous, with a straight to very oblique bristle-like appendage at apex; nerves obscure or rarely midnerve and 2 or more lateral nerves scarcely conspicuous; gland minute, basal, to 1 mm above pulvinus. Peduncles mostly 5-11 mm long, 0.4-0.8 mm wide. Heads 5-8 mm diam., (12-) 15-26-flowered, bright yellow; bracteoles with very attenuated lamina apex, usually almost as long as the spreading buds. Flowers 5-merous; calyx cupular, 0.6-1.1 mm long, dissected to 1/5, reddish papillose towards apex; corolla 1.7-2 (-2.2) mm long, dissected for c. 1/2. Pods erect, narrowly oblanceolate, straight-sided, 2.5-5 cm long, 4-6 mm wide, obliquely nerved; margins slightly thickened. Seeds oblique, narrowly oblong-elliptic, 3-4.5 mm long, brown; funicle-aril narrowly conical.
