Asplenium surrogatum is a species of fern in the family Aspleniaceae.[1][2] 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.[3]
Taxonomy
A global phylogeny of Asplenium published in 2020 divided the genus into eleven clades,[4] which were given informal names pending further taxonomic study. A. surrogatum belongs to the "Neottopteris clade",[5] members of which generally have somewhat leathery leaf tissue. It forms a clade with A. milnei and A. pteridoides, two other Lord Howe Island endemics, suggesting that all three species diverged after a single colonization of the island by their ancestor.[6] This clade is sister to a large group of Pacific Ocean spleenworts.[5]
