Passiflora subpeltata

Scientific Name

Passiflora subpeltata Ortega

Synonyms

Passiflora alba Link & Otto

Family

Passifloraceae

Common Names

passion flower, passion fruit, passionflower, white passion flower, white passion-flower, white passionflower, white passionfruit, wild grenadilla

Origin

Native to Mexico, Central America (i.e. Guatemala and Panama) and tropical South America (i.e. Venezuela and Colombia).

Naturalised Distribution

Widely naturalised in the coastal regions of eastern Australia (i.e. throughout eastern Queensland and the coastal districts of eastern New South Wales).

Also naturalised on some Pacific islands (e.g. Hawaii and Tonga).

Habitat

A common weed of roadsides, disturbed sites, waste areas, watercourses (i.e. riparian areas), urban bushland, closed forests, forest margins, open woodlands and plantation crops (e.g. sugarcane) in tropical and sub-tropical regions.

Habit

A vine with climbing or creeping stems, supporting itself with tendrils.

Distinguishing Features

Stems and Leaves

The stems are slender, hairless or nearly hairless (i.e. glabrous or sub-glabrous) and grow up to 5 m long. Tendrils are produced at the base of the leaf forks.

The alternately arranged leaves are hairless (i.e. glabrous) and borne on stalks (i.e. petioles) 2-6 cm long. Where the leaf stalk joins to the stems there is a two-lobed leafy structure (i.e. stipule) 1-4 cm long, that is somewhat obliquely heart-shaped. The leaf blades (3-10 cm long and 4-11 cm wide) are pale green with whitish or bluish-green undersides. They are three-lobed, with the lobes being cut about half-way into the centre of the leaf blade and having rounded tips (i.e. obtuse apices).

Flowers and Fruit

The white flowers (4-5.5 cm across) are borne singly in the leaf forks (i.e. axils). These flowers have six petals and six sepals, which are all very similar in appearance. They also have five prominent stamens and an ovary topped with three styles and large stigmas. Flowering occurs during spring and summer.

The fruit are pale green to bluish-green or yellowish when mature. These fruit are leathery berries (about 4 cm long) that are egg-shaped (i.e. ovoid) to almost round (i.e. sub-globose) in shape.

Reproduction and Dispersal

This species reproduces by seed, which are commonly spread by birds and other animals that eat the fruit.

Environmental Impact

White passionflower (Passiflora subpeltata) is regarded as an environmental weed in Queensland and New South Wales, and was recently listed as a priority environmental weed in at least one Natural Resource Management region.

Other Impacts

White passion-flower (Passiflora subpeltata) contains cyanic acid and is thought to be poisonous to humans and livestock if eaten in sufficient quantities. Unlike many other passionfruit species, its fruit are not edible.

Legislation

Not declared or considered noxious by any state government authorities.

Management
