Tectariaceae

Tectariaceae is a family of Leptosporangiate ferns in the order Polypodiales. It comprises 10 genera, of which Tectaria is by far the largest.

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 and Psammiosorus form a clade that is sister to the rest of 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 is probably most closely related to Hypoderris.
