Branchlets markedly angular, light brown or brown; ridges very prominent, fawn, resin-crenulated. Phyllodes in clusters of 2-6, linear, straight or curved, semiterete to flat, 4-14 mm long, 0.4-0.8 mm wide, thinly coriaceous, glabrous, furrowed; nerves inconspicuous, longitudinal; gland absent or inconspicuous. Heads 5-9 mm diam., 36-44-flowered, golden. Flowers 5-merous; calyx 1-1.5 mm long, dissected to 1/2-2/3, glabrous; corolla 1.7-2.5 mm long, dissected for 1/3-1/2, with petals striated; ovary glabrous, usually minutely tuberculate, with bulbous yellow cap on summit. Pods narrowly oblanceolate to linear-oblanceolate, basally tapered, flat, straight-sided, 2.7-5.5 cm long, woody, obliquely to almost longitudinally nerved, glabrous, scurfy when old, opening elastically at apex; margins and seed-partitions thick. Seeds oblique, broadly oblong-elliptic, 3.2-4.7 mm long, dark brown; pleurogram with fawn halo; areole closed; funicle-aril narrowly conical.
