A vine with a climbing habit and tendrils for support native to tropical America - a widespread weed, especially of disturbed sites in forests.
Stems to 4 m long have an unpleasant odour. Can be almost hairless (subglabrous) to a sparse or dense covering of white or yellow sticky hairs.
Leaves most often have three rounded lobes with pointed tips, but sometimes they are entire or five-lobed, alternately arranged along the stem, leaf stalks (petioles) 1-6 cm long, sticky hairs along margins. At the base of each leaf stalk is a tendril and a 1 cm long threadlike appendage (stipule) with sticky glands.
Flowers are typical of the passionfruit family and pinkish or white in colour (3-5 cm across). Fruit are dry berries partially enclosed by persistent, deeply-divided sepals with sticky (glandular) hairs.
Can be distinguished from two other similar species, corky passion vine (Passiflora suberosa) and white passion flower (Passiflora subpeltata), by its hairy leaves.
