Information
Perennial with tuberous root. Stems usually climbing, herbaceous becoming woody, up to 2.5 m long, often striate, sparsely hairy becomÂing scabridulous in older parts. Leaves ovate-cordate to suborbicular-reniform in outline, 20-90 x 15-80 mm, base cordate, sinus broad and shallow, apex acute or acuminate, margin ± crenate, entire or frequently 3-lobed, divided up to middle, terminal lobe ovate to ovate-trianguÂlar, constricted at base, basal lobes rounded, obliquely ovate to semi-orbicular, upper surface green, thinly hairy, lower surface mostly floc-cosely or cobwebby tomentose with soft white hairs when young except on yellow-bristly veins, glabrescent when older; petiole striate, hairy, 10-50 mm long. Inflorescence lax, cymosely 1-many-flowered; peduncle pilose, 20-150 mm long; bracteoles hairy, linear-lanÂceolate, 7-11 mm long; pedicels up to 15 mm long. Sepals equal, hairy, lanceolate, 10-15 mm long. Corolla funnel-shaped, 40-60 mm long, limb as much wide, shallowly 5-lobed, pale magenta, pink or purple, glabrous or with a few pilose hairs on midpetaline areas. Capsule sub-globose to ovoid, 7-9 mm in diameter, usually glabrous. Seeds compressed-globose, 3-4 mm long, yellow-pubescent, often with long white hairs on edges. Flowering time November to June, mostly March to May.
