It is the only member of the genus Benincasa. The fruit is fuzzy when young. The immature melon has thick white flesh that is sweet when eaten. By maturity, the fruit loses its hairs and develops a waxy coating, giving rise to the name wax gourd, and providing a long shelf life. The melon may grow as large as 80 cm in length. It has yellow flowers and broad leaves. The taste is rather bland.
