Myriopteris lanosa (Michaux) Grusz & Windham. Common name: Hairy Lipfern. Phenology: Jun-Oct. Habitat: Dry outcrops of felsic or intermediate-composition metamorphic, igneous, and sedimentary rocks. Distribution: CT, NY, PA, s. OH (pers.comm. 2021), s. IL, MO, and KS south to FL, AL, MS, LA, and e. TX, and disjunct in WI and MN.

ID notes: 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.
