Also known as: meal weed, meal scum.

Watermeal is recognized as the most difficult aquatic plant to control. It is the smallest of flowering plants; it can be dark to light green in color and resembles tiny grains of sand or cornmeal. It looks like very small dots covering the pond. Reproduction occurs by splitting, so complete coverage of a pond’s surface is rapid.
