Usually about 50 cm high, much branched, with shortly pubescent branchlets. Leaves mostly about 6 mm long, erect-spreading, very slightly incurved, lanceolate or ovate-lanceolate, very obtuse, at first apiculate, convex and bluntly keeled on the dorsal surface, flat or slightly concave on the ventral surface, at first pilose on the margins, becoming glabrous. Stipules minute, subulate. Flower-heads about 8 mm wide, terminal, solitary, involucred by pale leaves shortly over-topping the flowers. Bract and bracteoles alike, linear, apiculate, with caducous unicellular hairs on the dorsal surface, reaching nearly to the tips of the petals. Calyx-tube narrowly obconic, clothed with caducous hairs, with a narrow free upper margin: calyx-lobes subulate, apiculate, with caducous hairs on the dorsal surface. Petals about 2 mm long, elliptic, obtuse, clothed with caducous hairs on the dorsal surface. Anthers slightly more than 0.5 mm long, ovate. Ovary with persistent hairs on the summit: styles connate except at the tips. Fruit unknown.
