Adenia is a genus of flowering plants in the passionflower family, Passifloraceae. It is distributed in the Old World tropics and subtropics. The centers of diversity are in Madagascar, eastern and western tropical Africa, and Southeast Asia. The genus name Adenia comes from "aden", reported as the Arabic name for the plant by Peter Forsskål, the author of the genus.
All Adenia are perennial plants, but there are many different forms, including herbs, vines, lianas, shrubs, and trees. Many are succulents and some are pachycauls. Some have fibrous root systems and some have tubers.Adenia can be found in a wide variety of habitat types, from dry African deserts to wet Southeast Asian rainforests. There are some 100 species in the genus.
Adenia have alternately arranged leaves borne on petioles. There are two glands located near the attachment of the blade to the petiole. Most species are dioecious.Inflorescences of a few to many flowers occur in the leaf axils. There is a stipe below the flower. The calyx of sepals around the base of the flower has five lobes. The five petals are usually smaller than the sepals and may be whitish or greenish. The male flower has five stamens. In the female flower these are reduced to staminodes. There are three styles tipped with stigmas that may be long-hairy to very woolly. The fruit is a red capsule. Each black seed has a fleshy aril.
