Dryopteridaceae
The Dryopteridaceae are a family of leptosporangiate ferns in the order Polypodiales. They are known colloquially as the wood ferns. 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 Dryopteridoideae of a very broadly defined family Polypodiaceae '' sensu lato''. The family contains about 1700 species and has a cosmopolitan distribution. Species may be terrestrial, epipetric, hemiepiphytic, or epiphytic. Many are cultivated as ornamental plants. The largest genera are ''Elaphoglossum'' (600+), ''Polystichum'' (260), ''Dryopteris'' (225), and ''Ctenitis'' (150). These four genera contain about 70% of the species. Dryopteridaceae diverged from the other families in eupolypods I about 100 million years ago. Description The rhizomes are often stout, creeping, ascending, or erect, and sometimes scandent or climbing, with non clathrate scales ...

Pteridophyte Phylogeny Group
The Pteridophyte Phylogeny Group, or PPG, is an informal international group of systematic botanists who collaborate to establish a consensus on the classification of pteridophytes (lycophytes and ferns) that reflects knowledge about plant relationships discovered through phylogenetic studies. In 2016, the group published a classification for extant pteridophytes, termed "PPG I". The paper had 94 authors (26 principal and 68 additional). PPG I A first classification, PPG I, was produced in 2016, covering only extant (living) pteridophytes. The classification was rank-based, using the ranks of class, subclass, order, suborder, family, subfamily and genus. Phylogeny The classification was based on a consensus phylogeny, shown below to the level of order. The very large order Polypodiales was divided into two suborders, as well as families not placed in a suborder: Classification to subfamily level To the level of subfamily, the PPG I classification is as follows. *Class Lycopo ...

Maxonia
''Maxonia'' is a genus of ferns in the fern family Dryopteridaceae, subfamily Polybotryoideae, in the Pteridophyte Phylogeny Group classification of 2016 (PPG I).

Fern
A fern (Polypodiopsida or Polypodiophyta ) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate ( Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid fe ...
