Nymphoides indica is an aquatic plant in the Menyanthaceae, native to tropical areas around the world.^[1] It is sometimes cultivated, and has become a minor weed in Florida, where it resembles the native Nymphoides aquatica.^[2] Common names include banana plant, robust marshwort, and water snowflake;^[3]

Nymphoides indica spreads by rhizomes, forming clusters of leaves, with clustered white flowers about 1 cm across. The flowers are sometimes described as having five petals,^[4] but can have more.^{[citation needed]}
