Adiantum hispidulum, commonly known as rough maidenhair fern or five-fingered jack, is a small fern in the family Pteridaceae of widespread distribution. It is found in Africa, Australia, Polynesia, Malesia, New Zealand and other Pacific Islands. [1] Its fronds rise in clumps from rhizomes among rocks or in the soil in sheltered areas.

Taxonomy

Adiantum hispidulum was first described by Swedish botanist Olof Swartz in 1802. [2] Its species name is derived from the Latin hispis "hair" and means "minutely hairy". [3] Five-fingered jack is an alternative vernacular name. [4]

Description

Adiantum hispidulum grows in tufts or clumps among rocks or from the ground, its fronds arising from the short dark clumped rhizomes. The dark stipe measures up to 45 cm (18 in) in length. The fronds are divided into long and short narrow triangular or elliptic pinnae, each of which is divided again into smaller roughly rectangular, diamond-, or fan-shaped pinnules. Each pinnule may have 1 to 20 sori along its margins underneath. Young growth may have a pinkish tinge before it matures into the dark green foliage. [1] [5]

Distribution and habitat

The species ranges from tropical Eastern Africa, including South Africa, Mozambique, Malawi, Kenya and Tanzania, as well as Madagascar and the Comoros, Mauritius, to Asia through Malesia to all states of Australia (with the exception of Tasmania [6] ), as well as New Zealand and Pacific islands. [7] A common plant, Adiantum hispidulum is often seen growing in moist areas. In Australia it is found near rocks, in rainforest or open forest. [8]

Apart from its native range, it has naturalized in Macaronesia (the Azores, Madeira and Canary Islands), the Southeastern United States and Hawaii. [9]

Cultivation

Adiantum hispidulum is grown as an ornamental plant that adapts readily to cultivation, although may be slow growing. It is more tolerant of sun and drying out than other fern species. [3] According to the Royal Horticultural Society Adiantum hispidulum is hardy down to -5C to -10C.[ citation needed ]

<i>Adiantum</i> Genus of ferns

Adiantum, the maidenhair fern, is a genus of about 250 species of ferns in the subfamily Vittarioideae of the family Pteridaceae, though some researchers place it in its own family, Adiantaceae. The genus name comes from Greek, meaning "unwetted", referring to the fronds' ability to shed water without becoming wet.

<i>Adiantum capillus-veneris</i> Species of fern

Adiantum capillus-veneris, the Southern maidenhair fern, black maidenhair fern, maidenhair fern, and venus hair fern, is a species of ferns in the genus Adiantum and the family Pteridaceae with a subcosmopolitan worldwide distribution. It is cultivated as a popular garden fern and houseplant.

<i>Polystichum munitum</i> Western North American fern

Polystichum munitum, the western swordfern, is an evergreen perennial fern native to western North America, where it is one of the most abundant ferns in forested areas. It occurs along the Pacific coast from southeastern Alaska to southern California, and also inland east to southeastern British Columbia, northern Idaho and western Montana, with disjunctive populations in northern British Columbia, Canada; the Black Hills in South Dakota, United States; and Guadalupe Island off of Baja California, Mexico. Western swordfern is known to have locally naturalized in parts of Great Britain and Ireland.

Davallia is a genus of about 40 species of fern. In the Pteridophyte Phylogeny Group classification of 2016, it is the only genus in the family Davalliaceae, which is placed in the suborder Polypodiineae, order Polypodiales. Alternatively, the family may be placed in a very broadly defined family Polypodiaceae sensu lato as the subfamily Davallioideae.

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>Nephrolepis cordifolia</i> Species of fern

It is similar to the related fern Nephrolepis exaltata.

<i>Gleichenia polypodioides</i> Species of fern

Gleichenia polypodioides (L.) Sm., commonly known as coral fern, kystervaring or ystervaring due to its glabrous, brown, wiry stipes. The species is widespread in south- and east tropical Africa, southern Africa and the western Indian Ocean region. It occurs naturally in a broad coastal belt in South Africa, Lesotho, Eswatini, Angola, Malawi, Burundi, Tanzania, Mozambique, Zimbabwe, Mauritius, Réunion, Amsterdam Island and Madagascar, and was first described by Carl Linnaeus in 1771 under the name Onoclea polypodioides. Often forming dense and impenetrable thickets, sometimes over large areas, this rhizomatous perennial is an important pioneer in disturbed areas such as pine plantations. It is often mistakenly seen as an exotic invader rather than as a useful rehabilitation plant, a source of peat and growing medium, while showing exceptional resistance to herbicides.

Rhizome brown, 1–2.5 mm. in diam., creeping, with long-spined dark-brown scales up to 0.5 mm. in diam., with fronds spaced 2–20 cm. apart. Stipe castaneous, up to 60 cm. long and up to 1.5 mm. in diam., glabrous or with a few scales similar to those on the rhizome, shallowly sulcate. Frond bifurcate to reniform-lunate in outline, with 1 level of false dichotomy in each lateral branch system arising from each side of the terminal bud; all branches bearing distant foliar segments. Aborted apical buds up to 1.2 mm. long, clothed in dark-brown lanceolate laciniate scales. Pinnules linear, up to 7 x 0.75 cm., pinnate, usually glabrous, divided into sessile rounded entire triangular lobes, 3 x 2 mm., green to glaucous below. Sori partially immersed in the lamina, consisting of 2–4 sporangia, each in a separate but adjoining pit.

Tasmania is home to 'Australia’s largest cool temperate rainforests. Most of Tasmania’s rainforests occur in the North-West and throughout the North East highlands. Cool temperate rainforests typically have a heavy rainfall, cool climate, favor high altitudes and have a limited availability of light.

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

Asplenium appendiculatum, ground spleenwort, is a common native fern to Australia and New Zealand. It usually grows in cool damp conditions, among rocks, on logs or as an epiphyte.
