Sepals subequal, glabrous; outer 2 ovate-oblong, 7-8 mm, margin whitish, thin, apex obtuse, mucronulate; inner 3 ovate-elliptic, ca. 8 mm. Corolla white, pink, or lilac, with a darker center, funnelform, 3.5-5 cm, glabrous. Stamens unequal, included. Pistil included; ovary conical, glabrous. Stigma 2-lobed.

Commonly cultivated as a pot herb, Ipomoea aquatica is adapted to a warm, moist climate and cannot survive frost. Several races are recognized (without formal taxonomic designation) based on growing conditions (terrestrial vs. aquatic) and plant and flower color (greenish plants with white flowers vs. purplish tinged plants with lilac flowers). The plants have minor medicinal uses and also are used for forage.

Marshy habitats: ditches, ponds, rice paddies, waste areas. C to S China, native and cultivated [Bangladesh, Cambodia, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, New Guinea, Pakistan, Philippines, Sri Lanka, Thailand, Vietnam; Africa, Australia, Pacific Islands, South America]
