Shrub to 1 (-1.3) m high, erect ascending to semiprostrate, often spreading, glabrous, resinous, often with many slender stems branching at base. Bark smooth to slightly fissured at base, grey or brown. Branchlets angular towards apices with resin-crenulated ridges, finely lenticellate. Phyllodes rather spreading, narrowly elliptic to very narrowly elliptic, sometimes slightly wider below middle or ±linear, ±flat or sometimes slightly undulate, shallowly to markedly ±downwardly curved and often slightly sigmoid to sometimes straight, (0.4-) 0.7-2 (-3.5) cm long, (1-) 1.5-3 (-5) mm wide, coriaceous; nerves obscure or rarely midnerve and 2 lateral nerves scarcely conspicuous; lamina finely longitudinally wrinkled to appearing striate; apex with an oblique small (beak-shaped) mucro (hooked apiculate); gland absent or 1 minute basal gland to 1 (-2) mm above pulvinus. Peduncles 5-15 (-20) mm long, 0.4-0.6 mm wide. Heads 4-7 mm diam., 10-20 (-23)-flowered, yellow to golden, sometimes paler; bracteoles with triangular acute to acuminate lamina, mostly about same length or slightly longer than flower calyces; buds spreading. Flowers 5-merous; calyx cupular, 0.7-1 mm long, dissected to 1/10-1/5, reddish papillose towards apex; corolla 1.5-2 mm long, dissected by ½ or more. Pods erect, narrowly oblanceolate to ±linear, straight-sided, 2.5-5.5 (-6.5) cm long, 3-5 (-7) mm wide, obliquely nerved; margins subprominent. Seeds narrowly oblong-elliptic, 2.7-5 mm long, brown; funicle-aril narrowly conical.
