Characteristics

Glabrous perennial. Root tuberous, mostly subglobose, up to 130 mm in diameter. Stems one or several, erect or prostrate, woody at base, erect stems up to 300 mm long, prostrate ones up to 3 m or more. Leaves either palmately 3-9-sect (mainly on creeping stems) with segments 20-70 x 0.5-3.0 mm, or simple, linear to bilobed, 40-150 x 2-7 mm, sometimes pinnate, if three, then terminal segments partly fused to form a common rhachis; petiole of dissected leaves up to ±20 mm long, of simple leaves sometimes inconspicuous. Peduncles 1-flowered, usually very short; bracteoles often deciduous; pedicels short, thickened. Sepals lanceolate to elliptic, acute or acuminate, equal or unequal, 7-20 mm long. Corolla funnel-shaped, 40-70 mm long, 40-60 mm wide, usually bright magenta-pink, lighter outside and darker in centre and on midpetaline areas. Capsule subglobose-conical, 10-12 mm long and in diameter, apex often depressed, apiculate by style base. Seeds 4, 5-7 mm long, covered with long, shiny, fawn hairs.

Perennial herb; glabrous. Stems erect or procumbent. Leaves with blade either palmately 3-9-sect, with segments 20-70 x 0.5-3.0 mm, or simple, linear to bilobed, 40-150 x 2-7 mm.

Fruit a subglobose-conical capsule, 10-12 mm in diameter; seeds with long, shiny, fawn-coloured hairs.
Leaf lamina palmately 3–9 sect, with very narrow, linear or filiform segments 20–70 × 0·5–4 (10) mm., sometimes somewhat pinnate to distinctly pinnate, if 3 terminal segments are partly fused to form a common rachis, or entire, linear, sometimes linear spathulate, 4–10 (15) × 0·2–0·4 (0·7) cm.; petioles of dissected leaves up to about 2 cm. long, of simple leaves sometimes inconspicuous because the leaf is much narrowed at the base.
A herb. The branches are trailing. They have leaves spaced along them. These have erect flowering shoots along them. The leaf blade is divided into 3 narrow lobes up to 6 cm long by 3 cm wide. The central lobe is the longest. The flowers are erect. They are funnel shaped and 4 cm long and 4 cm wide at the mouth. The are pink or purple. It has a fattened tuber about 15 cm wide.
