Salviniaceae

Salviniaceae is a family of heterosporous ferns in the order Salviniales.[1] The Salviniaceae contain the two genera Azolla and Salvinia,[2] with about 20 known species in total.[3] Azolla was previously placed in its own family, Azollaceae, but research has shown Azolla and Salvinia to be sister genera with the likely phylogenic relationship shown in the following diagram.[4]
