Notes: Reports of Cheilanthes lanosa (Michx.) D.C. Eaton from the Olympic Peninsula (VPPN1) have not been confirmed by FNA or Buckingham et al. (1995).
FNA2: "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."
