Preliminary isozyme analyses support D. B. Lellinger's (1985) suggestion that Cheilanthes intertexta is a fertile allotetraploid hybrid between C. gracillima and C. covillei. It is morphologically most similar to the latter parent (see comments under C. covillei), but it is occasionally confused with C. gracillima, with which it apparently hybridizes to form sterile intermediates that have been called C. gracillima var. aberrans M. E. Jones. Cheilanthes intertexta may also be confused with C. clevelandii, with which it is partially sympatric. In addition to the characters given in the key, C. intertexta is distinguished from closely related sexual species by having larger spores averaging more than 55 µm in diameter.
