Asplenium septentrionale is found in scattered populations in a number of western states.  In the Four Corners, it is found in the Abajo Mountains in Utah and near Pagosa Springs in Colorado.  It is, according to Weber, "widely scattered in the mountains of the Northern Hemisphere, including Altai, the Alps, Pyrenees, Caucasus, and Scandinavia". 

The bright green narrow fronds of Asplenium septentrionale are often forked at the tips.  Overall the plant appears to be a small clump of grass tucked into a crevice.

Asplenium septentrionale is considered a rare plant through much of its range in the United States.

The genus was named by Linnaeus in 1753.  "Asplenon", from the Greek "a" ("without") and "splen" ("spleen") was the name given by Dioscorides to a Fern which he believed had the power to cure spleen diseases. This species was first named Acrostichum septentrionale by Linnaeus in 1753.  It was renamed Asplenium septentrionale in 1796 by George Hoffman.  "Septentrionale" is Latin for "northern".
