Stems compact to short-creeping, usually 4–8 mm diam.; scales often uniformly brown but at least some on each plant with well-defined, dark, central stripe, linear-lanceolate, slightly contorted, loosely appressed, persistent.

Discussion
Cheilanthes feei is an apogamous triploid of unknown parentage. It has small, beadlike blade segments similar to those of subg. Physapteris, but most morphological characteristics suggest a clear relationship to members of subg. Cheilanthes (T. Reeves 1979). The species is most often confused with C. parryi, from which it can be distinguished by its thinner, sparser pubescence and smaller ultimate segments.
