Flowers solitary or in few-flowered axillary clusters on peduncles, up to 6.5 cm long. Corolla up to 5 cm in diameter, pale yellow with a deep maroon-red centre. (from Flora of Zimbabwe website)

Glabrous, prostrate or occasionally twining, perennial herb. Stems herbaceous, up to 2.5 m long, sulcate and/or ribbed to almost winged. Leaves deeply palmately 5-9-lobed (lowest lobes sometimes unequally forked); lobes narrowly linear to oblanceolate, acute or obtuse, mucronate, 1-16 mm x 5-60 mm; petiole 12-25 mm long, slender. Inflorescence solitary or occasionally cymosely 2- or 3-flowered; peduncle 10-65 mm long, slender; bracteoles small, linear; pedicels 5-30 mm long, somewhat thicker upwards. Sepals subequal, pale yellowish green, elliptic with rounded apex, glabrous, coriaceous with a membranous edge, 7-10 mm long. Corolla pale or sulphur-yellow with deep red, maroon or deep magenta centre, 20-30 mm long, broadly funnel-shaped with spreading 30-40 mm wide, faintly lobed limb; midpetaline areas sparsely pubescent towards apex.
