Shrublet 0·5–0·75 m. tall, often spreading, canescent to glaucous with a short greyish velvety indumentum and additional long soft patent white hairs (rarely very sparse or almost lacking); stems greyish- or yellowish-green when young, soon glabrescent and becoming pale-purplish-brown, ultimately woody with an ash-grey smooth or finely longitudinally fissured bark. Leaf-lamina 2–5 (8) × 1–3 (5) cm., cordate-triangular to ovate-cordate, apex acute or somewhat acuminate or rounded, margin crenate to crenate-serrate often with minutely callous-mucronate serrations, dark-greyish-green and velvety above, much paler, glaucous-grey and finely velvety beneath, venation of lower surface somewhat prominent and conspicuous owing to its whitish or pale yellow colour; petiole usually shorter than the lamina, terete. Flowers yellow, solitary, axillary on main branches (not on condensed short axillary shoots); pedicels (10) 25–50 mm. long, slender, terete, articulated near the apex. Calyx 9–12 mm. long, widely campanulate, incised beyond the middle; lobes 6–8 mm. long, triangular-ovate to ovate-lanceolate, acuminate-apiculate, with a prominent median vein and usually in addition with a faint longitudinal vein on either side. Petals 11–14 × 8 mm., conspicuously ciliate in basal narrowed portion, often marked with reddish spots at the base and reddish-veined in lower portion. Staminal tube rather shortly conical, sparsely stellate-hairy to glabrous except at the very base. Fruit c. 14 × 5 mm., discoid-subglobose, truncate at the apex and widely umbilicate in the centre, stellate-hairy. Mericarps 20–30, c. 7 × 5 mm., ultimately black, 1-seeded, the upper edge slanting upwards into the usually sharply pointed to shortly apiculate dorsal apical angle. Seeds c. 2·5 mm. long, punctate-verruculose.
