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. [more]
The Marsileaceae are a small family of heterosporous aquatic and semi-aquatic ferns, though at first sight they do not physically resemble other ferns. The group is commonly known as the "pepperwort family" or as the "water-clover family" because the leaves of the genus Marsilea superficially resemble the leaves of a four-leaf clover (a flowering plant). Leaves of this fern have sometimes been used to substitute for clover leaves on Saint Patrick's Day. In all, the family contains 3 genera and 50 to 80 species with most of those belonging to Marsilea. [more]
At least 96 species and subspecies belong to the Family Salviniaceae.
