Description:	Shrublet up to c. 15 cm high, but sometimes flowering at ground level, usually forming low cushions from a polycephalous woody rhizome with generally smooth or gnarled brown bark; branches brown, densely pustulose-lenticellate. Leaves petiolate, rarely somewhat glaucous; lamina 3.2–12 × 0.9–2.8 cm, narrowly elliptic or narrowly oblanceolate to linear-oblong, roughly acute and shortly apiculate at the apex, with margin usually rather remotely curved-spinose-serrate, narrowly cuneate at the base, chartaceous; petiole c. 2 mm long, rather stout; stipules c. 3-7 mm long, linear-triangular, entire or divided, usually tardily deciduous. Flowers solitary or 2-5 in an umbellate or shortly racemose inflorescence, axillary on second-year shoots; pedicels 1.5-3.3 cm long in fruit, articulated at the base. Sepals 5-10 mm long in flower, elliptic, rounded, becoming carmine, 1.1–1.5 mm long, convex and erect or spreading in fruit. Petals bright yellow to orange-yellow, 12-20 × 7-13 mm, obovate and unguiculate. Stamens with anthers 1.75-3 mm long, a third to two-thirds as long as the filaments, straight, dehiscing by longitudinal slits. Carpels 5, with styles completely united and 5-lobed or globose stigma. Drupelets 6-10 × 5-7 mm, subglobose (rarely flattened-obovoid0, inserted near the base; embryo slightly curved.
