Branchlets angular towards apices, with yellow to red-brown upper portions, scurfy, hirsute; ridges not convoluted. Phyllodes fasciculate, usually 3 or 4 together, sigmoid-oblong, compressed, 1.2–3.1 mm long, 0.5–1.1 mm wide, oblique at base, with laterally mucronulate apex, thick, coriaceous; nerves inconspicuous; pulvinus absent or vestigial. Heads globular, c. 5–9 mm diameter, yellow or pale yellow.
