Information Prostrate or semiprostrate perennial herb; stems usually trailing along the ground, glandular-pubescent and with long weak or subsetose hairs. Leaf-lamina up to 4 (6) cm. in diam., suborbicular in outline, from very shallowly 3–5-lobed or 5-angular to 3–5-palmatipartite, stellate-pubescent above, stellate-tomentose beneath, apex subacute or somewhat rounded, margin crenate or subserrate, base cordate; petiole up to 5 cm. long, pubescent; stipules 3–4 mm. long, filiform, very caducous. Flowers up to 8 cm. in diam., yellow (rarely white) with reddish-purple centre, solitary, axillary; peduncle up to 10 cm. long, with a somewhat glandular pubescence, articulated near the apex. Epicalyx of 7–9 bracts; bracts 2·5 mm. long, filiform to very narrowly linear. Calyx 10–20 mm. long, densely pubescent, and stellate-setulose; lobes elongate-triangular, acute, joined at the base for up to 4–5 mm. Petals 3–5 × 1·5–2·5 cm., narrowly obliquely obovate, pubescent outside where not overlapping, glabrous inside. Staminal tube 7–18 mm. long; free parts of filaments up to 0·5 mm. long. Style-branches 2–5 mm. long. Capsule 12 mm. in diam., subglobose, densely stellate-pubescent; margins of valves setose. Seeds 2 × 2 mm., subreniform, sparsely minutely lepidote.

Information Annual herb from 6 cm. to 1 m. tall, erect or with arcuate-ascending branches from near the base; young stems densely pubescent or tomentellous with occasional longer weak or stiffish hairs. Leaf-lamina 1–5 × 1–5 cm., broadly ovate to suborbicular, often not or scarcely lobed towards the base of the stem, becoming shallowly to deeply 3-lobed towards the apex, hairy like the young stems on both surfaces, lobes broadly elliptic to almost linear, usually narrower in the upper leaves, apex acute to rounded, margin entire or coarsely serrate, base usually cordate; petiole up to 4·5 cm. long, hairy like the young stems; stipules 1–2 mm. long, filiform, caducous. Flowers 3–3·5 cm. in diam., white or pale yellow, solitary, axillary; peduncle up to 4 cm. long, slender, pubescent, articulated c. 2 mm. below the apex. Epicalyx absent. Calyx 8–13 mm. long, becoming somewhat scarious in fruit, hairy like the young stems; lobes narrowly lanceolate, joined for c. 3 mm. at the base. Petals up to 18 × 8 mm., narrowly obovate, glabrous. Staminal tube up to 12 mm. long, antheriferous only in the upper half; free parts of filaments 1·5–2 mm. long. Style-branches c. 0·5 mm. long. Capsule 5–8 × 5–6 mm., ellipsoid, carpels pointed or with short awns 0·5–1 mm. long. Seeds 2 × 1·5 mm., irregularly subreniform, densely verruculose otherwise glabrous.
