Leaves 3-7 mm long, erect-spreading, linear-lanceolate, acute or obtuse, trigonous, glabrous, flat and with a prominent median vein on the upper half of the ventral surface. Flowering heads 4-7 mm wide, globose, terminating short branchlets with modified leaves. Bract and bracteoles spathulate, villous on the lower half of the dorsal surface, slightly overtopping the calyx-lobes. Calyx-tube obconic, clothed with deciduous unicellular hairs: calyx-lobes spaced at the base, subulate, villous on the dorsal surface, reaching the middle of the petals. Petals about 1.5 mm long, oblong or widest at or below the middle and slightly narrowed from the middle upwards and downwards, obtuse, glabrous, with 2 minute keels on the lower half. Stamens scarcely twice as long as the petals to thrice as long: anthers oblong: thecae free in the lower half. Ovary slightly more than half inferior, tomentose on the upper part. Fruit unknown.
