Lemna aequinoctialis

About

Lemna aequinoctialis, the lesser duckweed, is a tiny, floating aquatic plant in the aroid family, found in quiet, still waters of the Southern U.S., as well as Mexico and some Caribbean Islands. Additionally, it can be found from the state of Virginia south through Florida, north to Nebraska and even into southern Wisconsin. It is also widespread in the American Southwest, from Texas to the coast of California, preferring lagoons and still ponds, which it accesses via seasonal flooding and occasional precipitation. Fronds are generally triple-nerved, green, and measure up-to 6 mm long. Flowers are single-ovulate, with a small utricular scale open on one side. Seeds have 8–26 ribs.
