Taxonomic Comments
Generally called 'Asplenium viride' in most floristic literature, but the Linnaean name 'Asplenium trichomanes-ramosum' has priority. However, the 1994 ICBN (Tokyo), Article 23, example 14, provides that the 'trichomanes' be dropped from this epithet, with the resulting name being 'Asplenium ramosum'; that name, in turn, was proposed for nomenclatural rejection (Zimmer & Greuter, Taxon 43: 303-304, 1994). The name Asplenium ramosum was rejected by the 2005 ICBN (Vienna). This reverts usage back to the next-oldest name, apparently 'Asplenium viride' again. FNA (1993, vol. 2) and Kartesz (1994) accept the name Asplenium trichomanes-ramosum.

Rank Reasons
Asplenium viride is a fern species that is widespread, but infrequent, across the temperate region of the Northern Hemisphere in North America, Europe and Asia. Threats and trends are unknown.
Range Extent Comments
This species is scattered across the temperate region of the Northern Hemisphere in North America, Europe and Asia. It is documented in Yukon, southwestern District of Mackenzie, British Columbia, Alberta, Ontario, Quebec, and Nova Scotia in Canada; central Alaska, Vermont, north New York, northern Missouri, Wisconsin (Dear County), Montana, South Dakota, Utah, northeast Nevada, Oregon, Washington, northern California in the United States, and Mexico. It is also found in southeast Greenland, Iceland and Eurasia. In California, it is only known from the Sierra Buttes (Skinner 1997). In Idaho, it occurs in Bear Lake and Clearwater Counties (Idaho Native Plant Society 1992). In Nevada, it is known only from Elko County (Kartesz 1988).
Occurrences Comments
By applying a 1 km separation distance to herbarium records and photo-based observations documented between 1992 and 2023, it is estimated that there are well over 300 occurrences globally (GBIF 2023, iNaturalist 2023, NatureServe 2023).
Ecology & Habitat

Description

Rhizomes short and scaly, but lacking median nerve; fronds 1 cm wide, up to 10 cm tall, densely tufted; stipes with deep groove and broad green margins, brown in lower part only, glabrous; pinnae herbaceous; sori near indistinct midvein (Hulten 1968).

Habitat

This species is epipetric, growing in crevices of limestone and other shaded calcareous rocks and on talus slopes (FNA 1993a).
