Thelypteridoideae
Thelypteridaceae is a family of about 900 species of ferns in the order Polypodiales. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), it is placed in the suborder Aspleniineae. Alternatively, the family may be submerged in a very broadly defined family Aspleniaceae as the subfamily Thelypteridoideae. The ferns are terrestrial, with the exception of a few which are lithophytes (grow on rocks). The bulk of the species are tropical, although there are a number of temperate species. These ferns typically have creeping rhizomes. The fronds are simply pinnate to pinnate- pinnatifid. There is either no frond dimorphism or only mild dimorphism, either open venation or very simple anastomosing. The sori are mostly reniform in shape and have indusia, except for the ''Phegopteris'' group. Classification During the early and mid 1900's all thelypterioid ferns were included in the genus '' Dryopteris'' because of the sorus shape. However, there are a great many d ...

Thelypteris
''Thelypteris'' (maiden ferns) is a genus of ferns in the subfamily Thelypteridoideae, family Thelypteridaceae, order Polypodiales. Two radically different circumscriptions of the genus are in use . In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the genus is a very small one with about two species. In other approaches, the genus is the only one in the subfamily Thelypteridoideae, and so includes between 875 and 1083 species. The genus name is from Greek ''thēlys'' "female" and ''pteris'' "fern". However, "female fern" usually refers to the common lady-fern. Taxonomy At one time, all thelypterioid ferns were included in the genus '' Dryopteris'' because of the sorus shape. However, there are a great many differences between the groups, and these plants are now segregated in their own family. Some researchers include the entire family Thelypteridaceae in the genus ''Thelypteris''. An intermediate position is to place the bulk in ''Thelypteris'' (correspo ...

Cyclosorus
''Cyclosorus'' is a genus of ferns in the family Thelypteridaceae, subfamily Thelypteridoideae, in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Other sources sink ''Cyclosorus'' into a very broadly defined genus ''Thelypteris'', or expand the genus to include other genera which PPG I keeps separate. Thus the online ''Flora of China'' suggests there are about 250 species compared to the two species suggested in PPG I. There are also fossil species known from the Eocene of South China and the Quaternary of Australia. The genus is named from the Greek, referring to the circular sori.Les Robinson - Field Guide to the Native Plants of Sydney, page 320 Species , the ''Checklist of Ferns and Lycophytes of the World'' accepted the following extant species, although noting that only two to four probably belonged in the genus ''sensu stricto'', the rest needing in future to be distributed among other genera. *''Cyclosorus angustipinnatus'' C.Chr. & Tardieu ex Tar ...

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 ...

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 ...

Aspleniineae
Aspleniineae is a suborder of ferns in the order Polypodiales. It is equivalent to the clade eupolypods II in earlier systems; it is also treated as a single very broadly defined family Aspleniaceae. The suborder generally corresponds with the order Blechnales as described by J. L. Reveal in 1993. Aspleniineae includes some important ferns, including ''Onoclea sensibilis'', the sensitive fern, which grows as a virtual weed throughout much of its temperate North American range, and ferns of the genus ''Thelypteris'', a genus that has shown remarkable speciation. It also includes one of the more common horticultural ferns, ''Matteuccia struthiopteris'', the ostrich fern. Taxonomy In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the group is treated as the suborder Aspleniinae, and divided into 11 families. Alternatively, it may be treated as a single, very broadly circumscribed family Aspleniaceae ''sensu lato ''Sensu'' is a Latin word meaning "in the sense ...

Phegopteris
''Phegopteris'' is a genus of ferns in the family Thelypteridaceae, subfamily Phegopteridoideae, in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). They are known collectively as the beech ferns. Species are native to Asia, North America and Europe. Taxonomy ''Phegopteris'' was first described in 1852 by Carl Borivoj Presl as an unranked taxon within the genus '' Polypodium''. It was raised to the rank of genus by Antoine Fée in the same year.
