Plants about 60 cm in height, much branched. Branchlets clothed with short grey pubescence. Leaves crowded 0.5-1.5 cm long: lamina erect-spreading, linear or linear-lanceolate, mucronulate, rounded at base, with re volute margins covering the whole or greater part of the lower surface; upper surface finely tubercled, at first furnished with grey, silky pubescence, becoming glabrous: petiole about 1 mm long. Inflorescence a many flowered capituliform raceme 0.5-1 cm long and 0.7-1.2 cm wide or a lax raceme about 1 cm long with the vegetative axis produced beyond the flowers. Bracts foliaceous, reaching to the summit of the flowers or longer. Bracteoles absent. Pedicels 1-3 mm long, clothed with grey pubescence. Flowers 3.5-5 mm long, covered on the outside with short or long, almost straight, grey hairs: calyx-tube 0.75-2.5 mm deep, cyathiform, ± 5-angled, lined up the sides with a thin disc: sepals deltoid-ovate, acute, 1-1.25 mm long, erect-spreading, flattened, with a prominent nerve from base to apex: petals at the mouth of the tube, 0.75 mm long; lamina cucullate, orbicular, sub-cordate at base; claw scarcely a third as long, narrowly cuneate or oblong: anthers 1-celled. Ovary turbinate: style 1.5-2 mm long, subulate, narrowed into a small, entire stigma reaching to about the middle or summit of the petals. Fruit 5-6 mm long, rotundate, becoming glabrous and blackish, with 10 vertical ridges, with a moderately sized depressed area on the summit.
