In 1990, Karl U. Kramer and coauthors treated Pleocnemia and 7 of the currently recognized genera as a subfamilyofDryopteridaceae.[3] 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.[4] In 2006, in a revision of fern classification, Tectariaceae was an accepted family.[5] In 2007, a molecular phylogeneticstudy of Dryopteridaceae included Pleocnemia and showed that it belongs in Dryopteridaceae.[6] Also in 2007, Dracoglossum was named as a new genus.[7] It has since been removed to Lomariopsidaceae.
As of November 2019[update], 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.[11]
