Cheilanthoideae
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 . Phylogenic relationships The following phylogram shows a likely relationship between Cheilanthoideae and the other Pteridaceae subfamilies. Although subfamily Cheilanthoideae itself is thought to be monophyletic, many of the genera into which it has been divided (including ''Cheilanthes'', ''Doryopteris'', ''Notholaena'', and ''Pellaea'') have been shown to be polyphyletic. Genera The division of the subfamily Cheilanthoideae into genera and species remains uncertain . Christenhusz et al. (2011), the Pteridophyte Phylogeny Group classification of 2016 (PPG I), and the November 2019 version of the ''Checklist of Ferns and Lycophytes of the World'' (''World Ferns'' 8.11 ...

Hemionitis
''Hemionitis'' is a genus of ferns in the subfamily Cheilanthoideae of the family Pteridaceae. Its circumscription varies greatly in different systems of fern classification. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), it was one of more than 20 genera in the subfamily Cheilanthoideae, and was said to have five species. Other sources treat it as the only genus in the subfamily, and so accept about 450 species. With the restricted circumscription, species are native to tropical America. Taxonomy The genus ''Hemionitis'' was first described by Carl Linnaeus in 1753. The genus name is pre-Linnaean, being used for example in the ''Hortus Cliffortianus'', and derives from the Greek word (), meaning 'mule', referring to the belief that the plants were sterile. (Linnaeus used the same word in the name "'' Asplenium hemionitis''".) The division of the subfamily Cheilanthoideae into genera varies greatly between sources . Christenhusz et al.

Pteridaceae
Pteridaceae is a family of ferns in the order Polypodiales, including some 1150 known species in ca 45 genera (depending on taxonomic opinions), divided over five subfamilies. The family includes four groups of genera that are sometimes recognized as separate families: the adiantoid, cheilanthoid, pteridoid, and hemionitidoid ferns. Relationships among these groups remain unclear, and although some recent genetic analyses of the Pteridales suggest that neither the family Pteridaceae nor the major groups within it are all monophyletic, as yet these analyses are insufficiently comprehensive and robust to provide good support for a revision of the order at the family level. Description Members of Pteridaceae have creeping or erect rhizomes. The leaves are almost always compound and have linear sori that are typically on the margins of the leaves and lack a true indusium, typically being protected by a false indusium formed from the reflexed margin of the leaf.

Aleuritopteris
''Aleuritopteris'' is a genus of ferns in the Cheilanthoideae subfamily of the Pteridaceae. As with some other genera of the Cheilanthoideae, molecular phylogenetic studies have suggested that it is not monophyletic, and so may need to be circumscribed differently in future. Taxonomy ''Aleuritopteris'' is one of a number of genera split off from '' Cheilanthes'' in some approaches, including the 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 relatio ... classification of 2016 (PPG I), in which the genus has about 40 species. , Plants of the World Online includes ''Aleuritopteris'' within '' Hermionitis'', a much smaller Cheilanthoideae genus 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. Species The Pteridophyte Phylogeny Group classification of 2016 (PPG I) placed seven species in the genus, although recognizing that the genus was then not monophyletic, since the New New is an adjective referring to something recently made, discovered, or created.

Calciphilopteris
''Calciphilopteris'' is a genus of ferns in the family Pteridaceae. It is native to India and China, southward to Australia.Jovita C. Yesilyurt and Harald Schneider. 2010. "The new fern genus ''Calciphilopteris'' (Pteridaceae)". ''Phytotaxa'' 7:52-59. (See ''External links'' below). Its four species grow in crevices in limestone or they cling to the rock itself. Taxonomy For a long time, the four species of ''Calciphilopteris'' were included in the polyphyletic genus ''Doryopteris''. Molecular phylogenetic studies have shown that ''Calciphilopteris'' is the most basal clade in the subfamily Cheilanthoideae. It is thus far removed from '' Doryopteris palmata'', the type species of ''Doryopteris''. ''Calciphilopteris'' was described as a new genus in 2010. The generic name is said to be derived from the Greek ''calx'' (limestone), ''philus'' (loving), and ''pteris'' (fern). ''Kalx'' can not be found in ancient Greek, however ''calx'' is the Latin word for "limestone",Le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Notholaena
''Notholaena'' (from Ancient Greek νόθο(ς) + χλαῖνα), cloak fern, is a genus of ferns in the Cheilanthoideae subfamily of the Pteridaceae. Ferns of this genus are mostly epipetric (growing on rock) or occurring in coarse, gravelly soils, and are most abundant and diverse in the mountain ranges of warm arid or semiarid regions. They typically have a creeping or erect rhizome and leaves that are pinnatifid to pinnate-pinnatifid with marginal sori protected by a false indusium formed from the reflexed margin of the leaf. Members of ''Notholaena'' also have a coating of whitish or yellowish farina (a powdery secretion that prevents desiccation) on the surfaces of the leaves. The farina is often limited to the abaxial (lower) leaf surface, but may occur on the adaxial (upper) leaf surface as well. Members of the related Pentagramma genus have a similar lower leaf-surface farina. The similar genus ''Argyrochosma'' also has farinose leaves, but in that genus the ultimat ...

Argyrochosma
''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. Species , the ''Checklist of Ferns and Lycophytes of the World'' recognized the following species: *''Argyrochosma chilensis'' (Fée ex J.Rémy) Windham *'' Argyrochosma connectens'' (C.Chr.)
