The ferns (Polypodiopsida or Polypodiophyta) are a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers.They differ from mosses by being vascular, i.e., having specialized tissues that conduct water and nutrients, and in having life cycles in which the branched sporophyte is the dominant phase.
Below are lists of extant fern families and subfamilies using the classification scheme proposed by the Pteridophyte Phylogeny Group in 2016 (PPG I). [1] The scheme is based on molecular phylogenetic studies, and also draws on earlier classifications, [1] particularly those by Smith et al. (2006), [2] Chase and Reveal (2009), [3] and Christenhusz et al. (2011). [4]

Other ferns which are also tree ferns, are Leptopteris and Todea in the family Osmundaceae, which can achieve short trunks under a metre tall. Fern species with short trunks in the genera Blechnum , Cystodium and Sadleria from the order Polypodiales , and smaller members of Cyatheales like Calochlaena , Cnemedaria , Culcita (mountains only tree ...
The Hymenophyllaceae, the filmy ferns and bristle ferns, are a family of two to nine genera (depending on classification system) and about 650 known species [1] of ferns, with a subcosmopolitan distribution, but generally restricted to very damp places or to locations where they are wetted by spray from waterfalls or springs.
Fern allies and ferns were sometimes grouped together as division Pteridophyta. [1] Another traditional classification scheme of living plants is as follows (here, the first three classes are the "fern allies"): Kingdom: Plantae. Division Tracheophyta (vascular plants) Class Lycopodiopsida, clubmosses and related plants (fern-allies)
