Aquatic plants have been difficult to classify, due to their reduced forms and thus lack of differentiating qualities and due to their reduced DNA. In the case of the aquatic ferns, a family was erected to include all Hydropteridaceae, which means water ferns. From the point of view of the Plant theory aquatic plants have a connection to the Hydrogen series, where only 1 possibility is available. Splitting the Salvianiales fits the structure better and the homeopathic picture fits better.TaxonomyIn the PPG1 classification Salviniales included the families Salviniaceae,, with as members Salvinia, Azolla and Marsileaceae.
Formerly, Salvinia was included in the Hydropteridales (Rothwell and Stockey, 1994) or Salviniales (A. Smith, 2006). Azolla was formerly also placed in its own family Azollaceae, leaving Salvinia as the only member of Salviniaceae.FamiliesPhase Remedy code Name
