Thelypteridaceae
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 ma ...

Amauropelta
''Amauropelta'' is a Monophyly, monophyletic genus of fern, the largest in the Thelypteridaceae family, with 233 species.Fawcett, S. & A.R. Smith. 2021. A generic classification of the Thelypteridaceae. Sida, Bot. Misc. 59. BRIT Press, Fort Worth Botanic Garden , Botanical Research Institute of Texas, U.S.A. The center of diversity of the genus is in the Neotropics, but the earliest-diverging lineages are from the Old World. The genus ''Amauropelta'' is very similar morphologically to the other two genera of the amaropeltoid clade, ''Coryphopteris'' and ''Metathelypteris'', differing from the first in the lack of sessile, resinous, reddish glands on the lamina between veins (except in the ''A. resinifera'' group) and from the second by the veins running to the margins. Within the Thelypteridaceae in the Neotropics it is easily recognised by the pairs of gradually reduced proximal pinnae, which vary from few to many, depending on the species, and the veins usually prominent a ...

Polypodiales
The Order (biology), 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 Tropics, tropical, semitropical and Temperate climate, temperate areas. Description Polypodiales are unique in bearing sporangia with a vertical Annulus (botany), 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 Sorus, indusia, but when presen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 :''The moth genus ''Dryopteris'' is now considered a junior synonym of ''Oreta.

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 Wo ...

Pseudophegopteris
''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. The Pteridophyte Phylogeny Group classification of 2016 (PPG I) recognizes three genera in the subfamily Phegopteridoideae: '' Macrothelypteris'', ''Phegopteris'' and ''Pseudophegopteris''. , both the ''Checklist of Ferns and Lycophytes of the World'' and ''Plants of the World Online'' regarded ''Pseudophegopteris'' as a synonym of ''Phegopteris''.

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 ...

Pteridophyte Phylogeny Group
The Pteridophyte Phylogeny Group (PPG) is an informal international group of systematic botanists who collaborate to establish 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). The classification was presented as a consensus classification supported by the community of fern taxonomists. Alternative classifications of ferns exist and are preferred by some. 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 subord ...
