Salviniaceae
EOL Text
Free-floating aquatic plants. Rhizome slender, branched, roots absent or simple, borne singly or in fascicles. Leaves either dimorphic, borne in whorls of three (Salvinia) or alternate in 2 rows ( Azolla); veins free or anastomosing. Sporangia in thin-walled sporocarps on submerged leaves or in axils of submerged lobes; heterosporous.

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