Azolla (mosquito fern, duckweed fern, fairy mass and water fern) is a floating fern in shallow water. It floats on the surface of water by means of nummers, small, closely overlapping scale like leaves with roots hanging in the water.

Azolla forms a symbiotic relationship with the cyanobacteria bacterium Anabaena Azollae (Blue green algae), which fixes atmospheric nitrogen to convert into plant nitrogen. Azolla is one of the aquatic petridophyte that may be used as animal food, green manure, bio fertilizer, for increasing soil fertility due to its high nutritional value.
