Lemnoideae is a subfamily of flowering aquatic plants, known as duckweeds, water lentils, or water lenses.They float on or just beneath the surface of still or slow-moving bodies of fresh water and wetlands.Also known as "bayroot", they arose from within the arum or aroid family (), so often are classified as the subfamily Lemnoideae within the family Araceae.
