| Salviniaceae | Azolla | Mosquito Fern |  (c) Cressler, Alan M. | ||
| Salviniaceae | Azolla caroliniana | Eastern Mosquito Fern, Water fern | Stagnant waters of interdune ponds, limesink ponds, old millponds, beaver ponds, floodplain sloughs, often locally abundant. | Widespread in the se. United States, extending irregularly north (partly from introductions) into s. New England and Minnesota, and south into the tropics. |  (c) Sorrie, Bruce A. - CC-BY |
| Salviniaceae | Azolla filiculoides | Large Mosquito Fern | Freshwater lakes, beaver ponds, artificial impoundments. | Native of w. North America, south into Mexico, Central America, South America. This species is reported for e. Georgia from a freshwater lake on Sapelo Island, McIntosh County (Bates & Browne 1981), presumably as an accidental introduction. Bunch & Hayden (2020) report it for two locations in the Coastal Plain of Virginia (Chesterfield and Sussex counties). It seems likely to be more widespread that currently reported. |  (c) mfeaver - CC-BY |
