Hypolepis parallelogramma is a species of fern native to the foothills of the Andes.
Its fronds are 3 to 8 metres (10 to 30 ft) long, borne on brown stipes which grow paler in color towards the blade, armed with 0.6 millimetres (0.02 in) thorns. The rachis, like the top of the stipe, is light brown to straw-colored. The blades are oblong in shape and tripinnate, the pinnulets at the base being lobed (tripinnate-pinnatifid). Scattered tiny hairs are present on the underside (only) of the costae, costules, and some veins. Sori are at the edge of the leaf with straw-colored pseudoindusia. [1] It most closely resembles H. melanochlaena , H. repens , and H. scandens , all of which are also large with thorny stems. [2]
The species was originally described by Gustav Kunze in 1834 as Cheilanthes parallelogramma. [3] Presl transferred it to the genus Hypolepis in 1836. [4] Schwartsburd and Prado designated a Peruvian collection by Poeppig made in 1829 as the lectotype in 2016. [1]
Hypolepis parallelogramma grows in the forests at the base of the Andes from Colombia and Venezuela south to Bolivia, at altitudes from 850 to 2,700 metres (2,800 to 8,900 ft). [5]
Cyathea is a genus of tree ferns, the type genus of the fern order Cyatheales.
Polystichum is a genus of ferns in the family Dryopteridaceae, subfamily Dryopteridoideae, according to the Pteridophyte Phylogeny Group classification of 2016. The genus has about 500 species and has a cosmopolitan distribution. The highest diversity is in eastern Asia, with about 208 species in China alone; the region from Mexico to Brazil has at least 100 additional species; Africa, North America, and Europe have much lower diversity. Polystichum species are terrestrial or rock-dwelling ferns of warm-temperate and montane-tropical regions. They are often found in disturbed habitats such as road cuts, talus slopes, and stream banks.
Alsophila capensis, synonym Cyathea capensis, is a regionally widespread and highly variable species of tree fern. It is indigenous to Southern Africa and South America.
Alsophila dregei, synonym Cyathea dregei, is a widespread species of tree fern in southern Africa.
Alsophila ferruginea, synonym Cyathea ferruginea, is a species of tree fern endemic to the Philippines. It is native to the islands of Negros, Palawan and Balabac. It grows in mossy forest up to an altitude of about 1,200 metres (3,900 ft).
Asplenium rhizophyllum, the (American) walking fern, is a frequently-occurring fern native to North America. It is a close relative of Asplenium ruprechtii which is found in East Asia and also goes by the common name of "walking fern".
Hypolepis (beadfern) is a genus of ferns described as a genus in 1806. The word is derived from Greek, meaning "under scale". It is found in tropical and subtropical regions, primarily in the New World but also in the Old World and on various oceanic islands.
Abacopteris is a small genus of ferns in the family Thelypteridaceae.
Asplenium resiliens, the blackstem spleenwort or little ebony spleenwort, is a species of fern native to the Western Hemisphere, ranging from the southern United States south to Uruguay, including parts of the Caribbean. Found on limestone substrates, it is named for its distinctive purplish-black stipe and rachis. A triploid, it is incapable of sexual reproduction and produces spores apogamously. First described by Martens and Galeotti in 1842 under the previously used name Asplenium parvulum, the species was given its current, valid name by Kunze in 1844. Several similar species are known from the tropics; A. resiliens may have arisen from these species by reticulate evolution, but precise relationships among the group are not yet certain.
Argyrochosma nivea is an Andean fern species in the genus Argyrochosma.
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 Pennsylvania to Arizona and Georgia, and Mexico.
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.
Argyrochosma dealbata, the powdery false cloak fern, is a small fern endemic to the central and southern United States. It grows on calcareous rocks, such as limestone. Its leaves are highly divided, with leaf segments joined by shiny, chestnut-brown axes, and their undersides are coated with white powder, giving the fern its name. First described as a species in 1814, it was transferred to the new genus Argyrochosma in 1987, recognizing their distinctness from the "cloak ferns".
Argyrochosma connectens is a small cheilanthoid fern endemic to Sichuan, China. It is the only member of its genus known from Asia. Relatively rare, it is found growing in the crevices of limestone rocks in hot, dry valleys. The species was long classified in the genus Pellaea, but after a phylogenetic study in 2015 was transferred to Argyrochosma.
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.
Argyrochosma lumholtzii is a rare fern in the family Pteridaceae known from Sonora, Mexico. It is quite similar to Jones' false cloak fern, but has black leaf axes and a less highly divided leaf. First described as a species in 1939, honoring the explorer Carl Sofus Lumholtz, it was transferred to the new genus Argyrochosma in 1987, recognizing their distinctness from the "cloak ferns".
Argyrochosma formosa is a fern known from eastern and central Mexico and Guatemala. It grows on rocky slopes, particularly on limestone. Unlike many members of the genus, it lacks white powder on the underside of its leaves. First described as a species in 1842, it was transferred to the new genus Argyrochosma in 1987, recognizing their distinctness from the "cloak ferns".
Culcita macrocarpa, the woolly tree fern, is a species of fern in the family Culcitaceae native to Macaronesia and parts of the Iberian Peninsula, where it might have been introduced. It is the only member of the order Cyatheales that is native to Europe.
Hiya is a genus of ferns belonging to the family Dennstaedtiaceae. Described in 2018, it resembles ferns of the genus Hypolepis but differs from it by multiple characteristics: scrambling, indeterminate and intermittent growth of fronds; stipule-like pinnules at the base of pinnae, and a rachis-costa architecture where the adaxial sulcus of the rachis is continuous with that of the costae and costules.
Hypolepis rugosula, is a common ground fern found throughout rainforests and wet sclerophyll forests, especially after recent disturbances in the forests.
