Distribution and Ecology
An introduced species, originally from Asia (probably India), cultivated in northern Australia and now naturalized in NEQ on the coastal lowlands between Cairns and Innisfail. Altitudinal range from near sea level to 100 m. Grows in rain forest regrowth and on old farmland.
This species grows quickly and will fruit in three years, when it may be 30-40 ft high. Its fruit is the biggest and one of the most complicated in creation, though it may be rivalled in size by exceptional marrows and pumpkins. Corner (1988).
