Discusión taxonómica
Cheilanthes mickelii is related to C. notholaenoides and C. cucullans, differing in the generally smaller size, short-creeping rhizomes, the presence of adaxial hairs, and longer abaxial hairs (ca. 1 mm). In addition, it differs from small specimens of C. notholaenoides in being chartaceous rather than coriaceous. The cited Chiapas collections were treated by Smith (1981) as Notholaena cinnamomea Baker, incorrectly.A
