Prostrate annual, 10–70 cm wide; branchlets densely tomentose with glandular hairs and occasional sessile stellate hairs and long simple hairs. Leaves broadly ovate to circular, 1–4 cm long, 2–3 cm wide, often 3–5 lobed, ± concolorous, becoming sparsely hairy above; base cordate; margins crenate; apex rounded. Flowers solitary; calyx obscurely 5-ribbed, campanulate, 5.5–10 mm long; lobes shortly acuminate, lined along midline; corolla yellow, c. equal to or exceeding calyx; lobes 3.8–6 mm long, asymmetrically rounded apically; staminal column c. 1.5 mm long, glabrous; styles 5–8. Fruit campanulate, 6–10 mm high (including awns), tomentose with stellate and simple glandular hairs, with occasional longer hairs along sutures, adjacent mericarps adhering for more than half their length, spreading widely from each other but remaining attached basally; mericarps 3-seeded, 6 mm high, 2.5 mm wide, with an apical awn 1.5–3 mm long, pointing outwards. Flowers year-round, but chiefly summer and winter to early spring.
