Widespread throughout Great Britain, but is absent from much of Scotland and Shetland. In Ireland, it is found mainly in the north and east. Elsewhere, the species has a very wide global distribution, absent only from polar areas and the tropics. Distribution information for this species can be accessed via the Charms of Duckweed (worldwide) and National Biodiversity Network Gateway (Britain only). This species spreads mainly through vegetative reproduction, but flowers are occasionally produced in shallow water exposed to full sun. When covering the entire surface of a pond, it can make the water appear solid, and in parts of the north-west of England, children were scared away from such ponds by the myth of Jenny Green-teeth, a pond elf or monster whose presence was indicated by duckweed; she was said to lure children into ponds and drown them.

Lemna minor (Common Duckweed or Lesser Duckweed) is a species of Lemna (duckweed) with a subcosmopolitan distribution, native throughout most of Africa, Asia, Europe and North America, occurring everywhere that freshwater ponds and slow-moving streams occur, except for arctic and subarctic climates. It is not reported as native in Australasia or South America, though is naturalised there. It is a floating freshwater aquatic plant, with one, two or three leaves each with a single root hanging in the water; as more leaves grow, the plants divide and become separate individuals. The root is 1-2 centimeter long. The leaves are oval, 1-8 millimeter long and 0.6-5 millimeter broad, light green, with three (rarely five) veins, and small air spaces to assist flotation. It propagates mainly by division, and flowers are rarely produced; when produced, they are about 1 millimeter diameter, with a cup-shaped membranous scale containing a single ovule and two stamens. The seed is 1 millimeter long, ribbed with 8-15 ribs.

Leptosiphon chrysanthus subsp. decorus - endemic to Mojave Desert in California.
