The pumpkin grows as a large, annual creeper. The stems, thick and non-lignified, elongate rapidly in one season, sometimes over 5 m, with some branching. The leaves are alternate, carried by a long upright petiole. They deploy a large palmate blade, almost rounded, presenting 3 important veins. The rod crawls or sometimes climbs on a support. The plant is covered with fine transparent hairs, unpleasant to the touch.
The flowers appear in summer, male flowers first, then female flower next, recognizable by its inferior ovary, a small ball under the flower. The stems should be long and branched to produce several female flowers.

The tamanu tree is indigenous to tropical Southeast Asia; it is found in Thailand, Vietnam, Myanmar, Malaysia, South India, Sri Lanka, and the Melanesian and Polynesian islands. It grows up to three meters tall, sporting cracked, black bark and elliptical, shiny leaves. The tamanu tree blooms twice annually with fragrant, white flowers, which later yield clusters of yellow-skinned spherical fruit. The fruit's pulp tastes similar to an apple, within which a large nut is embedded. The nut contains an odorless pale kernel. This kernel is dried in the sun until it becomes sticky with a dark, thick, rich oil; it must be protected from humidity and rain during drying.
This sticky oil is cold-pressed to make a greenish oil. Polynesian Natives believed the tamanu tree was a sacred gift of nature. It was an answer to skin protection from hot sun, high humidity and ocean wind.
