Distribution

From India and Sri Lanka to Indo-China, southern China, Thailand and throughout Malesia towards northern Australia; cultivated in this area and elsewhere.

Uses

Fruits of wild plants are used as a purgative and a vermifuge. In Indonesia, the inner pulp of the fruit is made into a syrup to treat cough. Immature fruits of cultivated forms are eaten boiled as a vegetable or in curries. Young shoots and leaves are also edible. The fruits become inedible upon ripening. In West Africa, the red fruit pulp is used as a kind of cheap tomato paste. Fruits of the wild forms are very bitter and inedible.

Observations

  • A monoecious, annual vine up to 6 m long, stem 4-angular, sparsely pubescent or glabrescent.
  • Leaves suborbicular or slightly kidney-shaped to broadly ovate, shallowly to deeply 3-7-lobed, 7-10 cm × 6-13 cm (in cultivated forms up to 25 cm across), base cordate, lobes rounded to obtuse, sparsely hirsute to almost glabrous on both sides.
  • Corolla about 3 cm in diameter; male flowers in lax, 3-25 cm long racemes, bracts small, up to 2 mm long; female flowers solitary or rarely in pairs.
  • Fruit ovoid, 4.5-7.5 cm × 3-4 cm, ripening to yellow or orange (in cultivated forms fruit linear, up to 100 cm long).
  • Seeds ovate-truncate, compressed.

The cultivated forms are traditionally distinguished as a species ( T. anguina L.), subspecies (subsp. anguina (L.) Greb.) or variety (var. anguina (L.) Haines), though it seems more appropriate to classify these in a cultivar group (e.g. cv. group Snake Gourd). Wild T. cucumerina is found in open forest, forest margins and scrub vegetation, up to 1000(-1500) m altitude.
