TaxonomyIn the Ppg1 classification placed Tectariaceae in the suborder Polypodiineae. Tectariaceae forms a closely related, but not monophyletic group with Davalliaceae, Lomariopsidaceae, Nephrolepidaceae and Oleandraceae in the Polypodiineae.
In 1990, Karl Kramer included Pleocnemia the genera of current Tectariaceae in Dryopteridaceae.
Kramer included Arthropteris, Psammiosorus and Oleandra in Oleandraceae. In 2006 Tectariaceae was an accepted family.
In 2007 Pleocnemia was shown to belong to Dryopteridaceae.
In 2007 Dracoglossum was named as a new genus and moved to Lomariopsidaceae.

Plant theoryIn the Plant theory the small, closely related families Davalliaceae, Lomariopsidaceae, Nephrolepidaceae and Oleandraceae are included Tectariaceae. They are placed in Subphase 7. These families do not form a monophyletic clade though, when Polypodiaceae is not included.
