Characteristics

Low perennial suffrutex, much branched and woody at the base, up to 30 cm, rarely up to 60 cm tall; stems usually branched throughout, terete or somewhat angled, usually greyish-green or greyish (rarely brownish), shortly and densely tomentose-velutinous, the upper portions usually slender and wiry. Leaf-lamina 2-4 x 1-2.5 cm, usually ovate-oblong to oblong but occasionally narrower or broader, apex subacute, margin irregularly rather coarsely serrate, base generally cuneate or more or less rounded, the upper surface dark green or brownish-green, usually sparsely and minutely stellate-pubescent, glabrescent, lower surface usually much paler, greyish-or yellowish-green, densely velutinous-tomentose and with prominent veins; petiole 3-10 mm long, tomentose-velutinous; stipules 4 x 1 mm, ovate-lanceolate to lanceolate, velutinous, sometimes somewhat falcate, rather persistent. Flowers deep yellow to orange, occasionally paler, solitary, axillary; pedicels 3-6 cm long, slender, terete, velutinous or tomentose, articulated near the apex. Calyx c. 8 mm long, obconical-campanulate to saucer-shaped, tomentose outside, and along the margin inside, incised to about the middle; lobes triangular, somewhat narrowed or acuminate at the apex, 5 mm broad at the base, with the median vein pinnately branching at about the middle of the lobe. Petals c. 10 x 8 mm, finely pubescent outside with simple hairs. Staminal tube with stellate hairs (usually sparse). Mericarps 7-9, c. 4 x 3 mm, muticous or subacute at the apex, usually stellate-hairy at the apex only, reticulate-veined on the flat lateral sides. Seeds brown, glabrous except for a small tomentose area around the hilum.
