Convolvulaceae
Convolvulaceae
Family of flowering plants including vines, herbs and shrubs, many with succulent tuberous or fleshy roots. African species of the genus Ipomoea form geophytes with large tubers that help them survive the dry season.
Ipomoea
Ipomoea
Large genus with over 500 species of vines, herbs and subshrubs, widely distributed across tropics and subtropics. Species of succulent interest are African geophytes with large succulent tubers that store water and nutrients during the dry season.
Rivea
Rivea
Genus of tropical and subtropical vines in the family Convolvulaceae, distributed mainly in Africa, Madagascar, and southern Asia. Its representatives produce showy tubular flowers and, in African species, fleshy tuberous roots that act as storage organs during the dry season. Historically confused with related genera such as Convolvulus and Ipomoea, its current circumscription is restricted to a small number of species.
