This is a somewhat small fern of rock surfaces, with a narrow blade (about 6" x 1.5"). The stipe is about 4" long, blackish and wiry, but still quite hairy/hirsute. The blades are quite hairy, especially below, bipinnate-pinnatifid, at times almost tripinnate. There are only about 7-10 pairs of pinnae. The sori are in a row along the margins of the pinnules on the blade underside, though the rolled-under leaf margins do not cover up sight of them (as in the more rolled-under leaves of M. tomentosa). Learn more at Vascular Plants of North Carolina.
Much the commonest and most widespread lipfern in our area, a sexual diploid, and the most eastern of a predominantly "southwestern" genus. Myriopteris lanosa is more sparsely hairy, "greener", smaller-fronded, and more mat-forming than the second most widely distributed and common Myriopteris in our region, Myriopteris tomentosa, per Weakley's Flora (2023).
