Perennial 0·75–2 m. tall, erect, much branched, shrubby, glaucous, usually densely leafy towards the tips of the branches, with an ash-grey (except on the leaves) appressed short velvety indumentum; stems herbaceous to wiry when young, usually with some longitudinally raised ridges decurrent from the leaf-bases or somewhat angular, later glabrescent and terete, ultimately woody and covered with a thin finely longitudinally fissured grey to brownish bark. Leaf-lamina 2–6 (10) × 4·5 (9) cm., thin but firm, glaucous or yellowish-glaucous above, slightly paler beneath, broadly ovate to ovate, apex shortly and usually bluntly acuminate, obtuse or acute (rarely rounded), margin usually rather coarsely crenate or crenate-serrate (occasionally crenulate to subentire), base cordate, venation on lower surface distinct and prominent; petiole 0·5–6 (12) cm. long, finely sulcate. Flowers yellow to apricot, solitary, one to few on short (6–8 cm. long) leafy axillary shoots; pedicels up to 5 cm. long, terete or in upper portion slightly angular, articulated at or above the middle. Calyx 7–9 mm. long, campanulate, incised to about the middle; lobes triangular-ovate, apiculate to acuminate, 1-nerved, finely ciliate. Petals 14–20 mm. long. Staminal tube hairy at the base. Fruit 14 mm. in diam., disk-shaped to depressed-hemispherical, nearly enclosed by the slightly accrescent calyx, umbilicate to truncate. Mericarps usually 18–24, 5–6 × 3–4·5 mm., blackish, shortly apiculate at the rounded apex, finely and somewhat floccosely stellate-tomentose dorsally and laterally in apical-dorsal region, 1-seeded. Seeds c. 2·5 × 1·5 mm., brown.
