Asplenium pteridoides

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.
Taxonomy.
A global phylogeny of "Asplenium" published in 2020 divided the genus into eleven clades, which were given informal names pending further taxonomic study. "A. pteridoides" belongs to the ""Neottopteris" clade", members of which generally have somewhat leathery leaf tissue. It forms a clade with "A. milnei" 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. This clade is sister to a large group of Pacific Ocean spleenworts.
