Information
Annual or perennial glabrous herb. Stems very slender, twining or sometimes prostrate. Leaf-lamina circular in outline, palmately divided to the base, up to 5 cm. in diam., often much less; lobes elliptic to lanceolate 2·6–4 × 1 cm. usually obtuse and apiculate at the apex and narrowed and subpetiolued at the base, the outer ones often 2-lobed; petiole 4–5 cm. long; pseudostipules present resembling the leaves but much smaller. Flowers axillary, solitary or in 2–3-flowered inflorescences; peduncle 4–5 cm. long, very slender, almost filiform; pedicels slender but thicker than the peduncle, more or less 1·7 cm. long, somewhat subclavate; bracteoles minute. Sepals elliptic or almost orbicular, 3–5 mm. long, subequal with membranous edges, usually obtuse but mucronulate, often muriculate. Corolla funnel-shaped, rose-purple or dark mauve, 8–17 mm. long. Capsule globose, glabrous. Seeds subglobose, brown, velvety-pubescent, with 5–10 mm. long white cottony hairs at the edges.
