Thyrses long-pedunculate on a tendril; pedicels 4-6 mm long. Flowers white; sepals 4, the 2 outer small, ovate, hispid, the 2 inner oblong, 6-8 mm long, glabrous; petals glabrous, obovate, attenuate, equal to the sepals, the scale on the inside of the petal oblong-obovate, 4-5.5 mm long, glabrous, with a lateral fold running the full length of the margin, the crest emarginate, the de-flexed appendage slender, villous at the apex, extending nearly or all the way to the base of the flower; disc with 2 slender, elongate, corniform glands, 2-3.5 mm long; staminate flowers with stamens to 8 mm long, united into a tube in the lower half, the tube weakly pubescent, the ovary borne within the staminal tube on a stipe to 1.5 mm long, elliptic, glabrous, the styles 3, the ovary, styles and stipe together to 3 mm long; bisexual flowers with the stamens to 4 mm long, glabrous, the filaments not united at the base, the ovary and style together to 6 mm long, the ovary 3-angled, oblong-elliptic, conspicuously hispid on the angles, the style 3 mm long, 3-branched in the upper half. Fruits elongate, obovate or elliptic capsules, membranous, inflated, acutely 3-angled, 5-6 cm long, acute at both ends, glabrous or nearly so; seeds globose, black, ca. 7 mm diam., the hilum round, conspicuous but much narrower than the body of the seed.

Perennial climber, 0.3-8.0 m high. Leaves biternate, stipulate; leaflets lobed, pubescent, upper surface sparsely pubescent, lower surface tomentose, apex acute, margins serrate; petioles up to 70 mm long. Flowers cream-coloured, in axillary thyrses; peduncle with a pair of tendrils at summit, sturdy. Sepals ovate, petaloid. Petals 4, ovate with petaloid appendages, hairy. Stamens 8; filaments free. Ovary villous; style branches filiform, hirsute. Flowering time Apr.-Nov. Fruit an inflated capsule, membranous, up to 66 mm long. Seeds black, globose, with a white, oblong hilum.
A straggling climber. It grows 3-5 m tall. The stems are angular. They are reddish and hairy. The leaves have 3 lobes and are twice divided. They are light green, thin and hairy. The leaf segments are oval and have teeth along the edge. The flowers are 0.8-1 cm across. They are white and have a scent. The fruit is a capsule which is 4.5-6 cm long and 3 sided. It is inflated and yellowish-green. There is a heart shaped scar on the seed.
Leaves biternate; petiole 2·1–7·3 cm. long, pubescent; leaflets with the terminal one 4·5–8·4 × 1·8–3·7 cm. and lateral ones (4)4·5–8·7(11·7) × 1·6–3·3 cm.; lamina ovate, upper surface bright green, sparsely pubescent, lower surface tomentose with occasional long brown hairs on the veins, or both surfaces almost glabrous, apex acute, margin serrate, base attenuate; stipules minute caducous scales.
Petals with 2 anterior and 2 posterior ones ovate bearing petaloid appendages c. 7 mm. long, and joined laterally, those of the posterior petals being apically recurved, passing across the disk, clavate and bearing patent hairs at the tips causing the latter to cohere.
