Cheilanthes covillei can be difficult to distinguish from the closely related C. intertexta and C. clevelandii; it differs from these two species in having glabrous blades and costal scales ciliate only on the basal lobes. Cheilanthes covillei is occasionally misidentified as C. fendleri because the cilia of the scales are often obscure; it is distinguished from the latter species by having rigid, dark brown stem scales that are strongly appressed. Cheilanthes covillei hybridizes with C. parryi and C. newberryi to form rare, sterile diploids known as C. × parishii Davenport and C. × fibrillosa (Davenport) Davenport ex Underwood, respectively. A third sterile diploid hybrid with C. fendleri has recently been discovered in central Arizona (M. D. Windham, unpublished).
