Myriopteris lendigera is a species of cheilanthoid fern with the common name nit-bearing lip fern. [2]
Myriopteris lendigera grows from long creeping rhizomes 1–3 mm in diameter with dark brown scales. Leaves can be scattered or clustered and range in length from 5 to 30 cm. The petiole is usually dark brown. The leaf blade is ovate-deltate to oblong-lanceolate and usually 4-pinnate (subdivided 3 times) at the leaf base. The blade is 1.5 to 8 cm (0.6 to 3.1 in) wide. The ultimate leaflet segments are round to slightly oblong and appear beadlike, with a diameter of 1–3 mm. Their abaxial (lower) surface is sparsely to moderately pubescent with coarse hairs and the adaxial (upper) surface is glabrous. Each leaflet curls under at the edge to form a false indusim. The spore-bearing sori are usually continuous around segment margins. [3]
Myriopteris lendigera is native to mountains in central and northern Mexico, Central America, Arizona and Texas in the United States, and extends into northeastern South America. It grows on rocky slopes and ledges, usually on igneous substrates, at altitudes from 1,300 to 2,400 m (4,300 to 7,900 ft).
The species was first described as Pteris lendigera by Antonio José Cavanilles in 1802, based on specimens collected by Luis Née in South America. [4] He did not explain his choice of epithet, which means "nit-bearing". It probably refers to the small, round shape of the leaf segments and the broad false indusium nearly covering their underside, which gives them an appearance similar to small beads or nits. [5] In 1806, Olof Swartz transferred the species to the genus Cheilanthes as Cheilanthes lendigera. [6] This placement would be widely accepted over the next two centuries, despite alternative arrangements, such as its transfer to Adiantum as A. lendigerum by Jean Louis Marie Poiret in Lamarck's Encyclopédie Méthodique, Botanique in 1810.

Myriopteris parryi, formerly known as Cheilanthes parryi, is a species of lip fern known by the common name Parry's lip fern.
Myriopteris clevelandii, formerly known as Cheilanthes clevelandii, is a species of lip fern known by the common name Cleveland's lip fern. It is native to southern California and Baja California in Mexico. The leaf is divided into small, bead-like segments densely covered with scales beneath. In M. clevelandii, some of these scales are reduced to hairlike structures, which help distinguish it from the closely related M. covillei. It is usually found growing on exposed rock, particularly igneous rock.
Myriopteris gracilis, formerly known as Cheilanthes feei, is a species of lip fern known by the common name slender lip fern or Fee's lip fern.
Myriopteris cooperae, formerly Cheilanthes cooperae, is a species of lip fern known by the common name Mrs. Cooper's lip fern, or simply Cooper's lip fern. Its leaves grow in clusters and are highly dissected into oblong segments, rather than the beadlike segments found in some other members of the genus. The axes of the leaves are dark and covered in long, flattened hairs. It is endemic to California, where it grows in rocky habitats, usually over limestone. The species was named in honor of its collector, Sarah Paxson Cooper; according to Daniel Cady Eaton, who described it in 1875, it was the first fern species to be named for a female botanist.
Myriopteris gracillima, formerly known as Cheilanthes gracillima, is a species of lip fern known by the common name lace lip fern. It is native to western North America, where it grows in rocky habitat from British Columbia to California to Montana.
Myriopteris newberryi, formerly Cheilanthes newberryi, is a species of lip fern known by the common name Newberry's lip fern. It is native to southern California and Baja California.
Myriopteris windhamii, formerly known as Cheilanthes villosa, is a species of lip fern, with the common name villous lipfern. It is native to the southwestern United States and Mexico.
Argyrochosma nivea is an Andean fern species in the family Pteridaceae.
Myriopteris tomentosa, formerly known as Cheilanthes tomentosa, is a perennial fern known as woolly lipfern. Woolly lipfern is native to the southern United States, from Virginia to Arizona and Georgia, and Mexico.
Myriopteris lanosa, the hairy lip fern, is a moderately-sized fern of the eastern United States, a member of the family Pteridaceae. Its leaves and stem are sparsely covered in hairs, but lack scales, hence its common name. One of the cheilanthoid ferns, it was usually classified in the genus Cheilanthes until 2013, when the genus Myriopteris was again recognized as separate from Cheilanthes. It typically grows in shallow, dry, soil, often in rocky habitats.
Myriopteris, commonly known as the lip ferns, is a genus of cheilanthoid ferns. Like other cheilanthoids, they are ferns of dry habitats, reproducing both sexually and apogamously. Many species have leaves divided into a large number of small, bead-like segments, the probable inspiration for the generic name. Hairs and/or scales are often present on both the upper and lower surfaces of the leaf, and their presence and appearance are useful in distinguishing between species. The genus is most diverse in Mexico, but species are found from southwestern Canada south to southern Chile, and one species is endemic to southern Africa.
Myriopteris maxoniana is a species of cheilanthoid fern endemic to the Mexican state of Tamaulipas. It is known only from one collection. It closely resembles Myriopteris longipila and was not described as a distinct taxon until 2004.
Myriopteris yatskievychiana is a small fern endemic to the Mexican state of Sonora, a member of the family Pteridaceae. It is known only from a single collection. While superficially similar to golden lip fern, a widespread species in Mexico, differences in its coating of hairs and its small size make it distinctive. One of the cheilanthoid ferns, it was usually classified in the genus Cheilanthes until 2013, when the genus Myriopteris was again recognized as separate from Cheilanthes.
Myriopteris aurea, the golden lip fern or Bonaire lip fern, is a moderately-sized fern native to the Americas, a member of the family Pteridaceae. Unlike many members of its genus, its leaf is only modestly dissected into lobed leaflets (pinnae), which are hairy both above and below. One of the cheilanthoid ferns, until 2013 it was classified in the genus Cheilanthes as Cheilanthes bonariensis, when the genus Myriopteris was again recognized as separate from Cheilanthes. It typically grows on dry, rocky slopes, and ranges from Mexico, where it is common and widespread, and the southwestern United States south and east through Central and South America as far as Chile and Argentina.
Myriopteris rufa, commonly known as Eaton's lip fern, is a moderately-sized fern of Mexico and the southwestern United States, with outlying populations in Costa Rica and the Appalachian Mountains. One of the cheilanthoid ferns, it was usually classified in the genus Cheilanthes, as Cheilanthes eatonii, until 2013, when the genus Myriopteris was again recognized as separate from Cheilanthes. It typically grows in rocky habitats, most frequently on limestone but also sometimes on basalt or shale.
Myriopteris rawsonii, formerly known as Cheilanthes rawsonii, is a perennial fern native to Namaqualand in Southern Africa. Like many other cheilanthoid ferns, it is adapted to dry conditions, bearing a thick layer of pale hairs on the underside of its pinnate-pinnatifid leaves. It is the only African representative of its clade of cheilanthoids, the otherwise American genus Myriopteris. It spends much of the year in a dried-out, dormant state, rehydrating and putting out new growth during winter rains. Its name honors the botanist and civil servant Sir Rawson W. Rawson.
Myriopteris wootonii, formerly known as Cheilanthes wootonii, is a species of fern in the Pteridaceae family with the common name Wooton's lace fern.
Myriopteris lindheimeri, formerly known as Cheilanthes lindheimeri, is a species of fern in the Pteridaceae family with the common name fairy swords.
Myriopteris scabra, commonly known as rough lipfern, is a species of cheilanthoid fern native to Mexico and the south-western United States (Texas).
Myriopteris yavapensis, formerly known as Cheilanthes yavapensis, is a species of cheilanthoid fern with the common name Yavapai lip fern native to the southwest United States.
