Asplenium viride

Green spleenwort was described by Carl Linnaeus in his 1753 Species Plantarum, under the name "Asplenium Trich. ramosum", with a type locality of "{{Lang|la|in Arvorniæ rupibus}}" (rocks in Caernarfonshire).{{cite book |author=Carl Linnaeus |author-link=Carl Linnaeus |year=1753 |title=Species plantarum: exhibentes plantas rite cognitas, ad genera relatas, cum differentiis specificis, nominibus trivialibus, synonymis selectis, locis natalibus, secundum systema sexuale digestas |url=http://www.botanicus.org/item/31753000802832 |volume=2 |publisher=Impensis Laurentii Salvii |location=Stockholm}} 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".{{cite book |title=International Code of Botanical Nomenclature (Tokyo Code) |chapter=Article 23: Names of species |editor1=W.

A global phylogeny of Asplenium published in 2020 divided the genus into eleven clades,{{sfn|Xu|Zhang|Rothfels|Smith|2020|p=27}} which were given informal names pending further taxonomic study. A. viride belongs to the "A. viride subclade" of the "A. trichomanes clade".{{sfn|Xu|Zhang|Rothfels|Smith|2020|p=39}} The A. trichomanes clade has a worldwide distribution. Members of the clade grow on rocks and usually have once-pinnate leaf blades with slender, chestnut- to dark-brown stalks. The A. viride subclade, which contains only A. viride and its allopolyploid descendant A. adulterinum, is exceptional in having green stalks.{{sfn|Xu|Zhang|Rothfels|Smith|2020|p=44}}

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.
