Nymphoides is a genus of aquatic flowering plants in the family Menyanthaceae. The genus name refers to their resemblance to the water lily Nymphaea. Nymphoides are aquatic plants with submerged roots and floating leaves that hold the small flowers above the water surface. Flowers are sympetalous, most often divided into five lobes (petals). The petals are either yellow or white, and may be adorned with lateral wings or covered in small hairs. The inflorescence consists of either an umbellate cluster of flowers or a lax raceme, with internodes occurring between generally paired flowers.
Species of Nymphoides are sold as aquarium plants, including the "banana plant", N. aquatica and the "water snowflake", N. indica. Species native to America are N. cordata in the Northeast and N. aquatica in the southeast. Nymphoides peltata is native to Europe, but can be found in America as an invasive aquatic weed. The non-native species N. hydrophylla and N. indica have also been reported from Florida (Jacono 2000).
Numerous species of Nymphoides can be found in Australia, and others exist in Southeast Asia, Africa and South America.
