Tectariaceae
Introduction '''Tectariaceae''' is a family of leptosporangiate ferns in the order Polypodiales. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the family is placed in the suborder Polypodiineae. Alternatively, it may be treated as the subfamily '''Tectarioideae''' of a very broadly defined family Polypodiaceae ''sensu lato''. The family comprises seven genera, of which ''Tectaria'' is by far the largest.
Taxonomy In 1990, Karl U. Kramer and coauthors treated ''Pleocnemia'' and 7 of the currently recognized genera as a subfamily of Dryopteridaceae. Two other genera, ''Arthropteris'' and ''Psammiosorus'', along with ''Oleandra'', constituted Kramer's Oleandraceae. It is now known that Kramer's version of Dryopteridaceae is polyphyletic. ''Arthropteris'' (including ''Psammiosorus'') lies within Tectariaceae and Tectariaceae is sister to a clade consisting of Oleandraceae, Davalliaceae, and Polypodiaceae. In 2006, in a revision of fern classification, Tectariaceae was an accepted family. In 2007, a molecular phylogenetic study of Dryopteridaceae included ''Pleocnemia'' and showed that it belongs in Dryopteridaceae. Also in 2007, ''Dracoglossum'' was named as a new genus. It has since been removed to Lomariopsidaceae.===Phylogeny===In 2016, a cladistic analysis of Tectariaceae separated two new genera, ''Draconopteris'' and ''Malaifilix'', from ''Tectaria'' ''sensu stricto''. PPG I 2016 Zhang et al. 2016 Fern Tree of Life===Genera===, the ''Checklist of Ferns and Lycophytes of the World'' accepted the following genera. ''Polydictyum'' was separated from ''Tectaria'' after the publication of PPG I in 2016. *''Arthropteris'' J.Sm. *''Draconopteris'' Li Bing Zhang & Liang Zhang*''Hypoderris'' R.Br. *''Malaifilix'' Li Bing Zhang & Schuettp. *''Polydictyum'' C.Presl*''Pteridrys'' C.Chr. & Ching*''Tectaria'' Cav. *''Triplophyllum'' Holttum
