Information
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 obo-vate 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.
Habitat
Distinguished by its palmately lobed leaves with densely white-tomentose undersides. Two varieties were distinguished in Meeuse (1957a: 742, 743), based mainly on the size of the corol­la. It now appears that the var. eenii cannot be upheld; the dimensions of the corolla overlap one another and all other features just about agree. The large-flowered specimens are pre­sumably merely luxuriant individuals that grew in favourable sites or after heavy rains.
