Duckweed, or water lens, are flowering aquatic plants which 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 Araceae, so often are classified as the subfamily Lemnoideae within the Araceae. Other classifications, particularly those created prior to the end of the 20th century, place them as a separate family, Lemnaceae.
