Characteristics

Suberect suffrutex up to c. 50 cm tall, densely grey-or grey-green-tomentose; branches sometimes decumbent; stems terete or somewhat angular when young, wiry, at length glabrescent and somewhat woody. Leaf-lamina 10-35 x 6-25 mm, elliptic, ovate, oblong or somewhat obovate to suborbicular, apex obtuse to rounded, margin rather coarsely serrate-crenate, base usually cuneate to rounded, both surfaces densely grey-green-tomentose, the lower surface slightly paler and usually with longer hairs; petiole 2-10 mm long, tomentose; stipules filiform, often somewhat patent, tomentose. Flowers yellow, axillary, solitary or occasionally 2-3-fasciculate, subsessile or pedicellate; pedicels up to 5(9) mm long. Calyx c. 6 mm long, subglobose-campanulate, 10-ribbed, tomentose, lobed to about the middle; lobes broad, subacute to shortly apiculate. Petals not much exceeding the calyx. Mericarps 7-8, c. 4 mm long, birostrate, separating at dehiscence, dorsally rugulose and very faintly cross-veined, laterally reticulate-striate; awns 2, c. 1 mm long, often connivent, setaceous, pungent. Seeds c. 2 x 1.5 mm, rather tumid, nearly smooth, glabrous.
