Asplenium viride

Asplenium viride is a species of fern known as the green spleenwort because of its green stipes and rachides. This feature easily distinguishes it from the very similar-looking maidenhair spleenwort, Asplenium trichomanes.

Nomenclature

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).[1] 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".[2] That name was later rejected in favour of William Hudson's later name Asplenium viride,[3] 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).[4]

Ecology

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.
