Plant theoryIn the
Plant theory Polypodiales is the only order in the subclass
Polypodiidae.
Polypodiidae is named Polypodiineae in the PPG1 classification, which is monophyletic. All its members are included in the
Polypodiales:
Hypodematiaceae, Didimochlanaceae,
Dryopteridaceae,
Polypodiaceae,
Tectariaceae,
Davalliaceae,
Nephrolepidaceae,
Lomariopsidaceae, and
Oleandraceae. The biggest family in this order is
Polypodiaceae, which is split in the 4 subfamilies
Drynarioideae,
Polypodioideae,
Grammitidoideae and
Microsoroideae.
TaxonomyIn the PPG1 classification the name
Polypodiales is used for a huge class including the Subclasses
Pterididae,
Aspleniidae, and
Polypodiidae. The ending “ales” in
Polypodiales suggests it to be an order, but in contrast it encompasses subclasses and orders. In the
Plant theory that clade is treated as the class
Polypodianae.
Alternatively, the families in
Polypodiales may be defined as members of
Polypodiaceae sensu lato, which is otherwise said the same as the subclass
Polypodiidae.
