Flowers white or purple, fragrant, showy; sepals 5, the outer ones with horn-like tips; corolla salver-form, the limb more or less flat, the tube very long and not dilated at the throat; stamens 5, exserted; style capitate and obscurely 2-lobed; ovules 4: Ivs. broad, alternate.—Three species in Trop. Amer., two of which are widely cult. By some, the genus is united with Ipomoea, but it is well distinguished by the salver- form rather than funnelform or bell-shaped corolla, by the exserted stamens and style, and by the night blooming habit.{{SCH}}
