GENUS INDEX

GENUS CODE: AZOLL
GENUS SCIENTIFIC: Azolla
GENUS AUTHORITY: Lam.
GENUS COMMON: Mosquitofern
GENUS SUMMARY: A small genus of about 6 species, floating aquatics, in tropical and warm temperate regions. Very un-fernlike, this floating aquatic looks superficially more like an aquatic liverwort. In some years and some places it occurs in great abundance, covering the surface of the water with a green or red mass of vegetation. Azolla has a symbiotic, nitrogen-fixing cyanobacterium, Anabaena azollae Strasburger; the nitrogen-fixing capabilities of Azolla (through its symbiont) have resulted in its use as a fertilizer, green manure, and livestock feed, much promoted in recent years, but used historically in Asian rice paddies for centuries (Lumpkin in FNA 1993b).
