Tectariaceae
Tectariaceae is a family of leptosporangiate ferns in the order Polypodiales. 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 Tectarioideae of a very broadly defined family Polypodiaceae ''sensu lato''. The family comprises seven genera, of which ''Tectaria'' is by far the largest. Taxonomy In 1990, Karl U. Kramer and coauthors treated ''Pleocnemia'' and 7 of the currently recognized genera as a subfamily of Dryopteridaceae.Karl U. Kramer (with Richard E. Holttum, Robin C. Moran, and Alan R.

Polypodiales
The order Polypodiales encompasses the major lineages of polypod ferns, which comprise more than 80% of today's fern species. They are found in many parts of the world including tropical, semitropical and temperate areas. Description Polypodiales are unique in bearing sporangia with a vertical annulus interrupted by the stalk and stomium. These sporangial characters were used by Johann Jakob Bernhardi to define a group of ferns he called the "Cathetogyratae"; the Pteridophyte Phylogeny Group has suggested reviving this name as the informal term cathetogyrates, to replace the ambiguously circumscribed term "polypods" when referring to the Polypodiales. The sporangia are born on stalks 1–3 cells thick and are often long-stalked. (In contrast, the Hymenophyllales have a stalk composed of four rows of cells.) The sporangia do not reach maturity simultaneously. Many groups in the order lack indusia, but when present, they are attached either along the edge of the indusium or in its ...

Malaifilix
''Malaifilix'' is a genus of ferns in the family Tectariaceae, with a single species ''Malaifilix grandidentata'', according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Taxonomy The genus ''Malaifilix'' was erected in 2016 for a species previously placed in ''Tectaria'' (''Tectaria grandidentata''). A 2016 molecular phylogenetic analysis of Tectariaceae had separated two new genera, '' Draconopteris'' and ''Malaifilix'', from ''Tectaria'' ''sensu stricto''. The analysis arranged the genera as in the following cladogram, where an alternative broader circumscription Circumscription may refer to: *Circumscribed circle *Circumscription (logic) *Circumscription (taxonomy) * Circumscription theory, a theory about the origins of the political state in the history of human evolution proposed by the American anthrop ... of ''Draconopteris'' has been added.

''Hypoderris'' is a genus of ferns in the family Tectariaceae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Taxonomy The genus ''Hypoderris'' was erected by Robert Brown in 1830. The type species, '' Hypoderris brownii'', was designated later by John Smith.

Pteridrys
''Pteridrys'' is a genus of ferns in the family Tectariaceae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Taxonomy The genus ''Pteridrys'' was erected by Carl Christensen and Ren-Chang Ching in 1934. The type species is ''Pteridrys syrmatica'', transferred from ''Aspidium syrmaticum''. A 2016 molecular phylogenetic showed ''Pteridrys'' to be related to two new genera, ''Draconopteris'' and ''Malaifilix'', separate from the clade containing ''Tectaria''.

Dryopteridaceae
The Dryopteridaceae are a Family (biology), family of leptosporangiate ferns in the Order (biology), order Polypodiales. They are known Common name, 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, sensu lato''. The family contains about 1700 species and has a cosmopolitan distribution. Species may be terrestrial plant, terrestrial, epipetric, hemiepiphyte, hemiepiphytic, or epiphytic. Many are Gardening, cultivated as ornamental plants. The largest genera are ''Elaphoglossum'' (600+), ''Polystichum'' (260), ''Dryopteris'' (225), and ''Ctenitis'' (150).

Polypodiineae
Polypodiineae is a suborder of ferns in the order Polypodiales. It is equivalent to the clade eupolypods I in earlier systems, and to the very broadly defined family Polypodiaceae in the classification of Christenhusz & Chase (2014). It probably diverged from the suborder Aspleniineae (eupolypods II) during the mid-Cretaceous. The divergence is supported by both molecular data and an often overlooked morphological characteristic which lies in the vasculature of the petiole. Most species that make up the suborder have three vascular bundles. The only exceptions are the grammitid ferns which have one, and the genus '' Hypodematium'' which has two. This differs from eupolypods II which mostly have two vascular bundles (except the well-nested blechnoid ferns which generally have at least three). Taxonomy In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the group is treated as the suborder Polypodiineae, and divided into 11 families. Alternatively, it may be trea ...
