Ipomoea ( /ˌɪpɵˈmiːə/) is the largest genus in the flowering plant family Convolvulaceae, with over 500 species. Most of these are called morning glories, but this can also refer to related genera. Those formerly separated in Calonyction (Greek καλός, kalos, good and νύκτα, nycta, night) are called moonflowers. The generic name is derived from the Greek words ιπς (ips) or ιπος (ipos), meaning "worm" or "bindweed," and όμοιος (homoios), meaning "resembling". It refers to their twining habit. The genus occurs throughout the tropical and subtropical regions of the world, and comprises annual and perennial herbaceous plants, lianas, shrubs and small trees; most of the species are twining climbing plants.

Kiribadu Ala (giant potato, I. mauritiana) is one of the many ingredients of chyawanprash, the ancient Ayurvedic tonic called "the elixir of life" for its wide-ranging properties.
