Stigma biglobose, 2mm in diameter. Sepals 5, long-aristate, expanded at base for 6-7mm, 2.5cm long in flower, longer in fruit, glabrous internally. Basal portion with dense long spreading hairs.

- This is an attractive vine but it can be tough to get rid of once established. This species frequently occurs in flower beds and cultivated areas. The flowers only last one day before wilting. Because this species is found throughout the world there is some confusion about it's origin. Most tend to agree the plant is from the American tropics.
The typical variety found is variety
, which has three-lobed leaves. Variety
, has leaves which are entire. This plant is less common than the former.
