Phyllodes linear or very narrowly oblanceolate, flat, straight or slightly subfalcate, 3.5–8.5 cm long, (2–) 3–8 mm wide, coriaceous, olive green, ± scurfy, resinous when young, with 1–3 longitudinal veins more prominent and 8–12 minor veins per mm; basal gland inconspicuous. Spikes 1–3 in phyllode axils, 0.6–3.5 cm long, yellow. Flowers 5-merous; calyx 0.4–0.5 mm long, dissected to ⅕–¼ of length, glabrous or silky on ribs, pubescent at base; corolla c. 1.5 mm long, dissected for ½ length, glabrous, scurfy; ovary glabrous. Pods linear or very narrowly oblong, raised over seeds on alternating sides, 2.5–6 cm long, 5–10 mm wide, chartaceous, light brown, glabrous, scurfy, slightly viscid. Seeds oblique, broadly oblong, 2.3–3.5 mm long, dark brown with an often paler small areole; pleurogram U-shaped, usually with pale halo.
