Found growing on rocks, usually along rainforest creek banks in Queensland, from the McIlwraith Range to about Maryborough, Queensland. Also known from Papua New Guinea and Indonesia. The type specimen was collected at Broad Sound.[1]
The specific epithet paleaceus is derived from Latin, meaning chaffy or scaly. Referring to the densely scaly stipes and rachis. This plant first appeared in scientific literature in 1810, in the Prodromus Florae Novae Hollandiae, authored by Scottish botanist, Robert Brown.[2]
Taxonomy edit
A global phylogeny of Asplenium published in 2020 divided the genus into eleven clades, which were given informal names pending further taxonomic study. Hybrids between A. paleaceum and Asplenium attenuatum have been collected. A. paleaceum is part of a closely related group of species that have been referred to as the A. paleaceum species complex.[3]
