Asplenium viride is known as the green spleenwort because of its green stipes and rachides. This feature easily distinguishes this species from the very similar-looking maidenhair spleenwort, Asplenium trichomanes.
Green spleenwort was described by Carl Linnaeus in his 1753 Species Plantarum, under the name "Asplenium Trich. ramosum", with a type locality of "in Arvorniæ rupibus" (rocks in Caernarfonshire). Under the rules of the International Code of Botanical Nomenclature, phrase names such as "Asplenium Trichomanes ramosum" are to be treated as orthographic errors – in this case, for "Asplenium ramosum". That name was later rejected in favour of William Hudson's later name Asplenium viride, which had a type locality of "in rupibus humidis in montibus Walliæ et in comitatibus Eboracensi et Westmorlandico" (damp rocks in the mountains of Wales, Yorkshire and Westmorland).
A. viride is a native species of northern and western North America and northern Europe and Asia. It is a small rock fern, growing on calcareous rock. It is a diploid species, with n = 36, and hybridizes with Asplenium trichomanes to produce Asplenium × adulterinum, found on Vancouver Island, British Columbia.
