Dryopteris inaequalis

Dryopteris inaequalis is an Afrotropical fern species that ranges from tropical and southern Africa to Madagascar. [1] It has been recorded in Tanzania, Zambia, Malawi, Mozambique, Zimbabwe and South Africa, [2] where it is present in the Western Cape, Eastern Cape and KwaZulu-Natal. [3] It is found on forest floors and along forest margins, from middle to high altitudes. [2]

Description

It has a creeping rhizome of up to 3.5 cm in diameter, that bears attenuate pale-brown rhizome-scales of up to 2 cm long. [2] The stipe is up to 80 cm long and is only densely scaled towards its base. The lamina is up to 90 x 33 cm, broadly to narrowly ovate with an acuminate apex with the basal pinnae not reduced, or barely so. [2] The pinnae are up to 33 x 16 cm and form an angle of more than 50° to the rachis. The pinnules are oblong to very narrowly oblong in outline. The rachis becomes glabrous with maturity. [2]

<i>Asplenium platyneuron</i> Species of fern

Asplenium platyneuron, commonly known as ebony spleenwort or brownstem spleenwort, is a fern native to North America east of the Rocky Mountains. It takes its common name from its dark, reddish-brown, glossy stipe and rachis, which support a once-divided, pinnate leaf. The fertile fronds, which die off in the winter, are darker green and stand upright, while the sterile fronds are evergreen and lie flat on the ground. An auricle at the base of each pinna points towards the tip of the frond. The dimorphic fronds and alternate, rather than opposite, pinnae distinguish it from the similar black-stemmed spleenwort.

<i>Dryopteris expansa</i> Species of fern

Dryopteris expansa, the alpine buckler fern, northern buckler-fern or spreading wood fern, is a species of fern native to cool temperate and subarctic regions of the Northern Hemisphere, south at high altitudes in mountains to Spain and Greece in southern Europe, to Japan in eastern Asia, and to central California in North America. The species was first described from Germany. It prefers cool, moist mixed or evergreen forests and rock crevices on alpine slopes, often growing on rotting logs and tree stumps and rocky slopes. It is characteristically riparian in nature, and is especially associated with stream banks.

<i>Dryopteris filix-mas</i> Species of fern in the family Dryopteridaceae

Dryopteris filix-mas, the male fern, is a common fern of the temperate Northern Hemisphere, native to much of Europe, Asia, and North America. It favours damp shaded areas in the understory of woodlands, but also shady places on hedge-banks, rocks, and screes. Near the northern limit of its distribution it prefers sunny, well-drained sites. It is much less abundant in North America than in Europe. The plant is sometimes referred to in ancient literature as worm fern, reflecting its former use against tapeworm.

<i>Gymnosphaera capensis</i> Species of fern

Gymnosphaera capensis, synonyms Alsophila capensis and Cyathea capensis, is a regionally widespread and highly variable species of tree fern. It is indigenous to Southern Africa and South America.

<i>Dryopteris affinis</i> Species of fern in the family Dryopteridaceae

Dryopteris affinis, the scaly male fern or golden-scaled male fern, is a fern native to western and southern Europe and southwestern Asia. It is most abundant on moist soils in woodlands in areas with high humidity, such as the British Isles and western France. In the Mediterranean region and the Caucasus it is confined to high altitudes.

<i>Myriopteris clevelandii</i> Species of 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.

<i>Dryopteris intermedia</i> Species of wood fern

Dryopteris intermedia, the intermediate wood fern or evergreen wood fern, is a perennial, evergreen wood fern native to eastern North America. It is a diploid species, and is the parent of several species of hybrid origin, including Dryopteris carthusiana. Other common names for this species include intermediate shield fern, fancy wood fern, fancy fern, glandular wood fern, American shield fern and common wood fern.

<i>Diplazium australe</i> Species of fern

Diplazium australe, commonly known as the Austral lady fern, is a small fern occurring in eastern Australia, New Zealand and Norfolk Island. The habitat is moist shaded areas, often occurring in rainforest.

<i>Adiantum viridimontanum</i> Species of fern

Adiantum viridimontanum, commonly known as Green Mountain maidenhair fern, is a fern found only in outcrops of serpentine rock in New England and Eastern Canada. The leaf blade is cut into finger-like segments, themselves once-divided, which are borne on the outer side of a curved, dark, glossy rachis. These finger-like segments are not individual leaves, but parts of a single compound leaf. The "fingers" may be drooping or erect, depending on whether the individual fern grows in shade or sunlight. Spores are borne under false indusia at the edge of the subdivisions of the leaf, a characteristic unique to the genus Adiantum.

<i>Dryopteris macropholis</i> Species of fern

Dryopteris macropholis is a species of fern. It is distributed on the Marquesas Islands.

<i>Argyrochosma nivea</i> Species of fern in the family Pteridaceae

Argyrochosma nivea is an Andean fern species in the genus Argyrochosma.

<i>Alsophila manniana</i> Species of plant

Alsophila manniana, synonym Cyathea manniana, the spiny tree fern or sheshino, is a species of tree fern. It is readily identified by the fierce spines on its trunk, and is widespread in the tropical regions of Africa.

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.

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.

<i>Argyrochosma peninsularis</i> Species of fern in the family Pteridaceae

Argyrochosma peninsularis is a fern endemic to Baja California Sur. It grows in dry, rocky places. First described as a species in 1939, it was transferred to the new genus Argyrochosma in 1987, recognizing their distinctness from the "cloak ferns". A dusting of powdery material and the presence of occasional scales on the central axis of its leaves help distinguish it from related species.

Argyrochosma pallens is a fern endemic to Mexico. It has narrow, divided leaves with brown axes; the leaves are dusted with white powder above and coated in it below. First described as a species in 1956, it was transferred to the new genus Argyrochosma in 1987, recognizing their distinctness from the "cloak ferns".

Argyrochosma palmeri is a fern endemic to Mexico. It has narrow, divided leaves with black axes; the leaves are coated in white powder below, and sparsely dusted or free of it above. First described as a species in 1887, it was transferred to the new genus Argyrochosma in 1987, recognizing their distinctness from the "cloak ferns".

<i>Sticherus tener</i> Australian fern

Sticherus tener, also known as silky fan-fern, is a common native ground-fern in the family Gleicheniaceae. It occurs growing along watercourses and drainage lines in rainforest that are dominated by Nothofagus cunninghamii. In Australia, it occurs in the states of Tasmania and Victoria. In New Zealand, it is known from two disjoint regions on the South Island. Like in other members of this genus, Sticherus tener have bright green fronds with repeatedly forking branches, branches bearing linear-shaped segments at almost right angles to the axis and form umbrella-like bush colony.

<i>Myriopteris rufa</i> Species of fern

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.

<i>Myriopteris rawsonii</i> Species of fern

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.
