A shrub, 30-60 cm high, with wiry branches. Branchlets very slender, reddish, sparsely pubescent with minute, adpressed, grey hairs. Leaves often widely spaced, 4-6 mm long: lamina linear or lanceolate-linear, acute or subobtuse, rounded at base, with closely revolute margins covering the lower surface, erect-spreading; upper surface rounded, smooth or wrinkled, at first thinly pubescent on the margins: petiole about 0.75 mm long. Capitula usually solitary, 4-5 mm wide, surrounded by the wide bracts of the outer flowers, flattened above. Bracts of the inner flowers about 1.25 mm long, linear, with a dense covering of white, silky hairs on the outer surface. Bracteoles 2, similar but smaller. Flowers 2 mm long: calyx-tube scarcely 0.5 mm deep, cyathiform, glabrous on both sides: sepals 0.75 mm long, deltoid-ovate, acute, sharply convex on the upper half, with a dense covering of woolly, white hairs on the outer surface. Petals inserted on the lower half of the tube, 0.5 mm long: lamina calyptriform, slightly recurved in the upper half: claw narrowly linear, about as long. Anthers 1-celled. Ovary narrowly turbinate, glabrous. Style together with the rounded, entire stigma 0.25 mm high. Fruit about 3 mm long, obconic, obtusely 3-angled, 3-humped above, with a small depressed area, glabrous, purple-brown.
