Asplenium milnei is a ground fern only found on Lord Howe Island. Commonly seen in lowland areas. [1]
A global phylogeny of Asplenium published in 2020 divided the genus into eleven clades, [2] which were given informal names pending further taxonomic study. A. milnei belongs to the "Neottopteris clade", [3] members of which generally have somewhat leathery leaf tissue. It forms a clade with A. pteridoides and A. surrogatum , two other Lord Howe Island endemics, suggesting that all three species diverged after a single colonization of the island by their ancestor. [4] This clade is sister to a large group of Pacific Ocean spleenworts. [3]
Asplenium bulbiferum, known as mother spleenwort, is a fern species native to New Zealand only. It is also called hen and chicken fern and, in the Māori language, pikopiko, mouku or mauku. Its fronds are eaten as a vegetable.
Asplenium ruprechtii, which goes by the common name Asian Walking Fern, is a rare, hardy, low-lying fern native to East Asia. It is a close relative of Asplenium rhizophyllum which is found in North America and also goes by the common name of walking fern. The species should not be confused with Asplenium sibiricum which is a synonym of Diplazium sibiricum.

Asplenium flaccidum is a species of fern in the family Aspleniaceae. The plant common name is drooping spleenwort or weeping spleenwort, and the species name flaccidum derives from the Latin root meaning drooping. An example occurrence of A. flaccidum is within a Nothofagus-Podocarp forest at Hamilton Ecological District on New Zealand's North Island in association with other fern species understory plants, crown fern, Blechnum discolor being an example.

Asplenium anceps is a diploid fern of family Aspleniaceae and one of the ancestors of the ferns that form the trichomanes complex. It lives exclusively in the three northernmost archipelagoes of the Macaronesian region, that is, is an endemic macaronesian fern. Its fronds are leathery and plastic and rachis is very thick, bright reddish brown and is traversed throughout its length of three wings, two on the upper surface to draw a groove and a third on the lower surface which is characteristic and unique to this species, since all other species of the trichomanes complex without. A typical feature of this fern, which he shares with all its hybrid offspring is the existence of a small atrium on the basis of medium and less pinnae directed toward the apex of the blade with one or two sori on its underside.
Asplenium goudeyi is a fern only found on Lord Howe Island. A common plant growing in a variety of situations. On trees, or rocks, boulders, cliff faces and sometimes in exposed positions. The wavy edged fronds are 50 to 75 cm long, and 12 to 18 cm wide.
Asplenium viride is a species of fern known as the green spleenwort because of its green stipes and rachides. This feature easily distinguishes it from the very similar-looking maidenhair spleenwort, Asplenium trichomanes.

Asplenium pteridoides is a species of terrestrial fern in the family Aspleniaceae. It is endemic to Australia's subtropical Lord Howe Island in the Tasman Sea. It is restricted to the cool, moist understorey of the forest on the island's southern mountains.
Asplenium surrogatum is a species of fern in the family Aspleniaceae. It is endemic to Australia's subtropical Lord Howe Island in the Tasman Sea. It grows both terrestrially and as an epiphyte. It occurs in forest at high elevations on the island's mountains.
Asplenium difforme is a plant in the spleenwort group of ferns. Its habitat is cracks in rocky headlands beside the sea. It is found in eastern Australia and Norfolk Island. Its fronds are thick and waxy to protect it from sea spray.
