Any small or minute aquatic plant of the family Lemnaceae that float on or near the surface of shallow ponds.
Any of a family of tiny plants of the family Lemnaceae, especially of the genus Lemna, found floating on the surface of still water throughout most of the world, except the polar regions and tropics. Each plant consists of a flat, circular, leaflike structure 0.4 cm/0.15 in or less across, with a single thin root up to 15 cm/6 in long below.
The plants bud off new individuals and soon cover the surface of the water. Flowers rarely appear, but when they do, they are minute and located in a pocket at the edge of the plant.
