Myriopteris gracilis, formerly known as Cheilanthes feei, [1] is a species of lip fern known by the common name slender lip fern or Fee's lip fern.
Myriopteris gracilis grows from a short creeping rhizome with pale to red-brown scales usually with a dark mid-stripe. The leaves are gray to pale green and 6 to 18 cm long and 1.5 to 3 cm wide. Each leaflet on the leaf is divided into lobes which are divided once more into rounded segments (3-pinnate). The undersides of the segments are concave and densely covered with short pale to dark tan hairs. The sori line the edges of the segment undersides and may be buried under the hairs. The fern reproduces asexually by apogamy. [2]
Myriopteris gracilis is native to much of western North America from British Columbia and Alberta to northern Mexico, and throughout much of the central United States. It is found in rocky areas, generally on calcareous rock such as limestone where it grows in cracks and crevices. [2]
Based on plastid DNA sequence analysis Myriopteris gracilis is part of the lanosa clade of Myriopteris . Its closest analyzed relatives are Myriopteris parryi and Myriopteris longipila . [3]
Myriopteris covillei, formerly known as Cheilanthes covillei, is a species of cheilanthoid fern known by the common name Coville's lip fern. Coville's lip fern is native to the southwestern United States and Mexico.
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 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.
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 intertexta, formerly Cheilanthes intertexta, is a species of lip fern known by the common name coastal lip fern. It is native to montane California and western Nevada, Oregon east of the Cascades, and with a disjunct population in central Utah. It grows in dry rocky habitats in sun, typically in rock cracks with little or no soil.
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.
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, 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 alabamensis, the Alabama lip fern, is a moderately-sized fern of the United States and Mexico, a member of the family Pteridaceae. Unlike many members of its genus, its leaves have a few hairs on upper and lower surfaces, or lack them entirely. One of the cheilanthoid ferns, it was usually classified in the genus Cheilanthes as Cheilanthes alabamensis until 2013, when the genus Myriopteris was again recognized as separate from Cheilanthes. It typically grows in shade on limestone outcrops.
Myriopteris yatskievychiana is a small fern native to Mexico, a member of the family Pteridaceae. It is known only from a single collection in the Mexican state of Sonora. 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 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 fendleri, formerly known as Cheilanthes fendleri, is a species of fern in the Pteridaceae family with the common name Fendler's lip fern. It is native to the southwest United States and northern Mexico.
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.
Myriopteris chipinquensis is a fern endemic to Mexico, a member of the family Pteridaceae. One of the cheilanthoid ferns, it was classified in the genus Cheilanthes until 2013, when the genus Myriopteris was again recognized as separate from Cheilanthes. It grows in oak-pine forests of the Sierra Madre Oriental, often with the very similar and closely related Myriopteris tomentosa.
