A shrub about 60 cm high, with ascending virgate branches sparsely pilose with grey hairs. Leaves 0.7-1.2 cm long: lamina erect-spreading, linear-lanceolate, apiculate, cordate at base, with closely revolute margins covering the lower surface; upper surface tubercled (on some plants obscurely so) and villous on the revolute portions and depressed midrib, at length glabrous: petiole 1-1.5 mm long. Inflorescence a terminal capitulum, 1.5-2.5 cm long, cylindric or conical, dense, many-flowered. Bracts of the lower flowers foliaceous; those of the upper 5-6 mm long, lanceolate, acuminate, ciliate, dorsally villous. Bracteoles 5-10, linear, 4-5 mm long, dorsally villous. Flowers shortly stipitate, 5.5-6 mm long: calyx-tube 1.5 mm deep, campanulate, shortly villous on the upper half of the outer surface, glabrous elsewhere: sepals about 3 mm long, lanceolate, acuminate, covered outside with ascending, straight, white hairs; inner surface sharply convex, pubescent on the angle. Petals inserted shortly below the mouth of the tube, 0.75 mm long, setaceous, incurved. Anthers 1-celled. Ovary turbinate, glabrous. Style 0.5 mm long, stout, surmounted by 3 very short, erect stigmatic lobes. Fruit about 8 mm long, obovate-rotundate, glabrous, with a small depressed area on the summit.
