▪ plant genus
also spelled  Ipomaea 
 genus of about 500 mostly warm-climate trees, shrubs, and twining and trailing herbaceous plants of the family Convolvulaceae with funnel-shaped flowers.

      The genus Ipomoea is important to humans for the beauty of its flowers and for the tuberous roots of two species. sweet potato (I. batatas), a perennial, forms roots as it trails along the ground. The edible “potatoes” are enlarged food-storage portions of the roots. Its leaves are oval to lobed, and the 5-cm (2-inch) flowers are pink to rose violet. It probably originated in tropical South America. Jalap (I. purga) is an upright herb with solitary, reddish flowers, native in tropical Mexico. Its apple-sized, turnip-shaped roots are the source of an ancient purgative, still in use. Heavenly blue morning glory (I. violacea)—a twining, perennial vine, usually cultivated as a garden annual—bears clusters of blue to purplish, sometimes white, flowers, 12 cm across, among heart-shaped leaves. It is native to tropical America. This vine bears seeds containing the alkaloids d-lysergic and d-isolysergic acids (similar to LSD), and the seeds are used traditionally among Mexico's Zapotec Indians for ceremonial and curative purposes. Common morning glory (I. purpurea), an annual vine that bears heart-shaped leaves and purple, pink, or white flowers about 7 cm (3 inches) across, has become a troublesome weed in parts of southeastern North America. One of the largest flowering ipomoeas is the moonflower (I. bona-nox, or Calonyction aculeatum), a rampant, perennial climber with 15-cm (6-inch) white, fragrant, night-blooming flowers. It contains a milky juice used for coagulating Castilla rubber. Bush morning glory (I. leptophylla), with tuberous roots and erect branches to about 120 cm (47 inches) tall, bears 7.5-cm purple or pink flowers. It is native to central North America. The morning glory tree, or casahuate (I. arborescens), is one of several similar tropical American tree and shrub morning glories.
