Characteristics

Perennial with a thin, woody taproot. Stems annual, several to many, suberect, twining or prostrate, several metres long, slender, pilose. Leaves palmately 3-or 5-lobed nearly to base, 20-140 mm wide, basal sinus rounded or obtuse, thinly pilose above, densely white cobwebby tomentose below, except on the conspicuous main nerves which have yellowish or brownish hairs; lobes linear-lanceolate to obovate or broader, lateral lobes in 3-lobed leaves with an extra rounded lobe or auricle; margins subentire, ciliate; petiole 20-80 mm long, pilose. Inflorescence a dense, 1-to few-flowered head; peduncle pilose, up to 100 mm long; bracts hairy, linear to lanceolate, up to 15 mm long; pedicels very short. Sepals subequal, hairy outside, 6-15 mm long, lanceolate. Corolla funnel-shaped, magenta-purple, mauve or cream-coloured with darker magenta centre, rarely completely white, 12-32 mm long, limb spreading 20-40 mm wide; midpetaline areas pilose. Capsule subglobose, glabrous, 6-8 mm in diameter. Seeds pubescent, 4-5 mm long, hairs often arranged in small tufts, sometimes with long white hairs on angles in upper half. Flowering time September to July, mostly January to March.

Leaf lamina palmately 3-or 5-lobed nearly to the base, 2–11 × 2–14 cm., green or yellow-green, with thin appressed pilose hairs above, densely covered with a white cobwebby tomentum beneath except on the main nerves and main veins which are covered with yellowish or brownish stiff, appressed to patent hairs and thus clearly marked out; lobes varying from obovate to narrowly elliptic, lanceolate, oblanceolate, linear-lanceolate or ovate-lanceolate except the basal ones in 5-lobed leaves which are shorter and relatively broader, apex or central and first pair of lobes subacute to acuminate, often cuspidate; margins entire or subentire, more or less distinctly ciliate; petioles more or less as long as the leaves, slender or stouter, pilose.
Perennial herb. Stems procumbent or suberect. Leaves with blade deeply palmately 3-or 5-lobed, 20-40 mm in diameter, lower surface densely covered with white cobwebby hairs and prominently veined. Flowers: in a dense, 1-few-flowered head; calyx lobes narrowly ovate, acute, hairy; corolla 12-20 mm long, magenta-purple, mauve, cream-coloured or white with darker magenta centre; Jan.-Mar. Fruit a subglobose, glabrous capsule, 6-8 mm in diameter; seeds pubescent, hairs often in small tufts and sometimes with long hairs along angles.
Inflorescence a dense few-flowered pedunculate head, rarely (by reduction) flowers solitary; peduncle up to 12 cm. long, slender or stouter, pilose as in stems and petioles; bracts linear or lanceolate up to 15 mm., hairy; pedicels very short.

Corolla funnel-shaped, magenta-purple, mauve, cream, or white, with darker magenta centre, 12–32 mm. long; midpetaline areas pilose.
Seeds pubescent, with the hairs often arranged in small tufts and sometimes with long white hairs on the angles in upper half.
Stems twining, climbing, prostrate or suberect young ones, up to several metres, slender or stouter, pilose.
