Characteristics

Shrublet, low, usually under 30 cm tall, many stems from a woody base, new growth tomentose with ashy-grey, bunched, stellate and simple rather long hairs. Stipules subulate, about 7 mm long, usually turning a dark colour. Leaves ovate-oblong, oblong or obovate-oblong, 1-4 cm long, 0.8-2.3 cm broad, on both surfaces thickly ashy-grey stellate-tomentose at first, becoming thinly so, more or less truncate at the apex, rounded to broadly cuneate at the base, coarsely crenate-dentate; petiole 0.3-1.5 cm long. Inflorescence axillary, flowers usually solitary on slender cernuous pedicels, 5-10 mm long. Epicalyx-bracts broadly ovate about 5 mm long, oddly shaped, usually with a short basal claw, apex acute or rounded, ashy tomentose on both surfaces. Calyx with lobes lanceolate, about 7 mm long and 2.5 mm broad, dorsally tomentose pubescent, glabrous on inner face except at the tip. Petals orange-yellow, about 6 mm long, usually shorter than the calyx. Stamens almost as long as the ligulate, 3 mm long staminodes. Ovary subglobose, tomentose in upper half; style about 2-5 mm long, branches about 1.5 mm long; ovules 2-3 in a cell. Capsule densely tomentose with mixed pubescence.
