Etymology: (Greek: dry kill, from plant death in dried habitats) Note: Used as green manure in rice paddies because of nitrogen-fixing algae in upper leaf lobe; species identification difficult, depends in part on fertile material (generally 0 on herbarium specimens). Species hybridize in culture.
Unabridged Note: Evard & Van Hove (2004) treated Azolla microphylla as a synonym of Azolla filiculoides, suggesting that plants here called Azolla microphylla might instead belong to Azolla cristata Kaulf., although no California material was referred to this sp. by them.
