Tectariaceae

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.
The following cladogram for the suborder Polypodiineae (eupolypods I), based on the consensus cladogram in the Pteridophyte Phylogeny Group classification of 2016 (PPG I), shows a likely phylogenetic relationship between Tectariaceae and the other families of the clade.
In 2016, a cladistic analysis of Tectariaceae separated two new genera, "Draconopteris" and "Malaifilix", from "Tectaria" "sensu stricto". The analysis arranged the genera as follows:
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.
