A moderately branched shrub, usually 30-40 cm high, with wiry branches. Branchlets rather slender, clothed with short, erect-spreading, grey pubescence. Leaves closely set, 3.5-6 mm long: lamina erect-spreading, almost always somewhat incurved, linear, with a laterally compressed, acute apex, or obtuse, slightly cordate at base, with closely revolute margins covering the lower surface; upper surface smooth, usually pitted and at first pilose on the margins, soon becoming glabrous. Petiole 1-1.5 mm long. Capitula solitary or on short branchlets and clustered, 0.5-1.2 cm wide, hemisphaeric, many-flowered, involucrate with many leaves having enlarged petioles. Bracts 1.5-2 mm long, linear or acicular, covered with long, grey hairs on the outer surface. Bracteoles 2, like the bracts. Flowers stipitate, 2-3.5 mm long: calyx-tube 0.5-0.75 mm deep, cyathiform, sparsely clothed outside with coarse, deciduous hairs, lined with an inconspicuous disc: sepals 1.25-1.75 mm long, ovate-lanceolate, acute, angular-convex on the apical half of the inner surface, overtopped by a dense covering of straight, grey hairs on the outer surface. Petals inserted on the upper half of the tube, scarcely 0.5 mm long: lamina orbicular, cucullate, with a dorsal ridge: claw as long, cuneate-linear. Anthers 1-celled. Ovary obconic, sparsely villous with long, deciduous, ascending, grey hairs, stigma minute, sessile.
