Mosquito fern. Azolla = Greek for 'dry kill' because it dies in a dry habitat. Found floating on shallow standing water among cattails. Means fern-like or looking like a fern, from the Latin?felix?or filicis, "a fern." 'Azolla?is a 'superorganism', consisting of not just the fern but a diverse array of symbiotic bacteria. It is this unique microbiota that converts nitrogen into organic forms and makes?Azolla?a perfect bio-fertilizer. Asia?s farmers have long known this, growing?Azollatogether with rice to provide a natural fertilizer to bolster rice productivity.'In a special leaf cavity,?Azolla?hosts a microbe called?Nostoc?that converts atmospheric nitrogen into food for its host. The Azolla researcher from Duke who is working to sequence the Azolla genome is the same woman who recently named a genus of ferns after Lady Gaga!
amazing bloom of red water fern and duckweed occurred on our largest pond last week
I have been informed it is likely not red agae because it rarely grows in fresh water. Any guesses as to what it is would be appreciated.

Azolla (mosquito fern, duckweed fern, fairy moss, water fern) is a genus of seven species of aquatic ferns in the family Salviniaceae. They are extremely reduced in form and specialized, looking nothing like conventional ferns but more resembling duckweed or some mosses.
