Information
Suffrutex up to c. 1·25 m. tall, erect or occasionally spreading (usually after having been grazed), usually branched from the base, with a short dense stellate usually somewhat rough pubescence and usually with additional ± sparse long patent hairs and often glandular-viscid when young; stems terete, firm, green or yellowish-green, woody at the base, ultimately with a thin greyish bark. Leaf-lamina 4–10 (15) × 3–9 (13) cm., broadly ovate-cordate to suborbicular-cordate, sometimes shallowly 3-lobed, apex acuminate, margin usually shallowly but distinctly and regularly serrate or crenate with minutely apiculate serrations, upper surface dark green, finely and somewhat scabridly stellate-pubescent, lower surface slightly paler, similarly hairy; petiole longitudinally sulcate, as long as or shorter than the corresponding blade. Flowers yellow to orange, in the axils of the upper leaves; peduncle c. 4 cm. long, erect-patent, 2–4-flowered at the apex; pedicels c. 2 cm. long, articulated in the upper 6 mm. (sometimes a solitary pedicel in the same axil as the peduncle but shorter than the latter). Calyx c. 8–12 mm. (accrescent to c. 9 × 12 mm. in fruit), shallowly cupular, lobes 4·5 mm. long, triangular or ovate-lanceolate, usually distinctly acuminate into a sulcate acumen. Petals 5–7 mm. long, ciliate at the base and sometimes also at the apex. Staminal tube densely stellate-hairy. Fruit of about 8 mericarps. Mericarps c. 9 × 3 × 2–2·5 mm., 2–3-seeded, ultimately light brown, ± radiate-spreading, pungently long-awned, with subulate curved outwardly spreading awns. Seeds c. 2 × 2 mm., dark brown, rugulose-papillose.
Habitat
Found mainly in rocky places, often in semi-shade, sometimes gregarious.
