Aquatic ferns

IntroductionAquatic 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. Plant theoryIn the Plant theory Salviniales is split in Azollaceae, Salviniaceae and Marsileaceae. They are all having their own order and subclass, which are placed respectively in the classes Equisetanae, Lycopodianae and Polypodianae.OrdersNr Series Remedy code Order
