Trachypteris is a small genus of ferns in the subfamily Cheilanthoideae of the family Pteridaceae. [1] Three species are native to the tropical South America, one ( Trachypteris drakeana ) to Madagascar. [2]
As of December 2021 [update] , the Checklist of Ferns and Lycophytes of the World recognized the following species: [2]
Cheilanthes, commonly known as lip ferns, is a genus of about 180 species of rock-dwelling ferns with a cosmopolitan distribution in warm, dry, rocky regions, often growing in small crevices high up on cliffs. Most are small, sturdy and evergreen. The leaves, often densely covered in trichomes, spring directly from the rootstocks. Many of them are desert ferns, curling up during dry times and reviving with the coming of moisture. At the ends of veins sporangia, or spore-bearing structures, are protected by leaf margins, which curl over them.
Cyathea is a genus of tree ferns, the type genus of the fern order Cyatheales.
Pellaea is a genus of ferns in the Cheilanthoideae subfamily of the Pteridaceae. The genus name is derived from the Greek word πελλος (pellos), meaning "dark," and refers to the brown stems. Many members of the genus are commonly known as cliffbrakes. They primarily grow in rocky habitats, including moist rocky canyons, slopes, and bluffs.
Alsophila hermannii, synonym Cyathea christiiCopel., is a species of tree fern endemic to Mindanao in the Philippines, where it grows in forest at an altitude of 900–1800 m. The trunk is erect and may be 5 m tall or more. Fronds are bi- or tripinnate and 2–3 m long. The stipe is covered with some warts and narrow, brown scales. Sori occur near the midvein of fertile pinnules and are covered by thin, fragile indusia.
Alsophila is a genus of tree ferns in the family Cyatheaceae. It has also been considered to be a section in the subgenus Cyathea of the genus Cyathea.
Campyloneurum is a genus of ferns in the family Polypodiaceae, subfamily Polypodioideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). They are commonly known as strap ferns.
Saccoloma is a fern genus in family Saccolomataceae. It is the only genus in the family in the Pteridophyte Phylogeny Group classification of 2016, but further investigation is needed. It is pantropical and its species are found in wet, shaded forest areas. Saccoloma species are characterized by an omega-shaped (Ω) vascular bundle in the cross-sections of their petioles. The common name soralpouch fern is used for Saccoloma.
Tectaria is a genus of fern in the family Tectariaceae, according to the Pteridophyte Phylogeny Group classification of 2016. Halberd fern is a common name for species in this genus.
Thelypteris is a genus of ferns in the subfamily Thelypteridoideae, family Thelypteridaceae, order Polypodiales. Two radically different circumscriptions of the genus are in use as of January 2020. In the Pteridophyte Phylogeny Group classification of 2016, 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.
Argyrochosma is a genus of ferns known commonly as false cloak ferns. The genus is included in the Cheilanthoideae subfamily of the Pteridaceae. Species now in this genus were previously treated as members of related genera Notholaena or Pellaea but were segregated into their own genus in 1987. These ferns, of which there are about 20 species, are mostly native to the Americas, from North to South and including the Caribbean, while one species, A. connectens, is known from Sichuan, China. They are commonly found growing in cracks between rocks. Their leaves are generally shorter than 40 centimeters and have rounded bluish or grayish green segments. Often the lower surface of the segments is coated in a white dust, and the sporangia contain brown spores.
Microgramma is a genus of ferns in the family Polypodiaceae, subfamily Polypodioideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). They are commonly known as vine ferns or snakeferns.
Arthropteris is a small genus of ferns in family Tectariaceae, according to the Pteridophyte Phylogeny Group classification of 2016. It was previously placed in the families Oleandraceae or Davalliaceae. The genus is native to Australia, Europe, Asia and Africa. Around 12 to 21 species are considered part of this genus. The name Arthropteris is from the Greek, meaning "jointed fern", referring to the joint at the base of the petiole.
Cheilanthoideae is one of the five subfamilies of the fern family Pteridaceae. The subfamily is thought to be monophyletic, but some of the genera into which it has been divided are not, and the taxonomic status of many of its genera and species remains uncertain, with radically different approaches in use as of December 2019.
Doryopteris is a genus of ferns in the subfamily Cheilanthoideae of the family Pteridaceae.
Pityrogramma, the silverback ferns, or goldback ferns, is a fern genus in the subfamily Pteridoideae of the family Pteridaceae.
Odontosoria is a genus of ferns in the family Lindsaeaceae.
Tapeinidium is a genus of ferns in the family Lindsaeaceae with about 19 species. Species are native to south-eastern Asia, from Thailand to New Guinea, and into the western Pacific. Tapeinidium pinnatum has been introduced into India.
Syngramma is a genus of ferns in the subfamily Pteridoideae of the family Pteridaceae. Species are native to south-east tropical Asia and the Pacific.
Vaginularia is a genus of ferns in the subfamily Vittarioideae of the family Pteridaceae in the Pteridophyte Phylogeny Group classification of 2016. Other sources sink the genus into Monogramma, a genus not recognized in PPG I.
Mildella is a genus of ferns in the subfamily Cheilanthoideae of the family Pteridaceae. Species are native to Mexico, Central America and the Caribbean.
