Elevation: 800–2900 m
Like its close relative Cheilanthes lindheimeri, C. wootonii is an apogamous triploid of unknown parentage. With the recognition of C. yavapensis as a distinct species, the name C. wootonii is restricted to populations with leaf blades that appear glabrous adaxially, costal scales that are often ciliate only in the proximal half, and stem scales that are usually brown and loosely appressed. In addition, C. wootonii is distinguished from C. yavapensis by having smaller spores, averaging less than 62 µm in diameter. These characteristics can be subtle, and some specimens will be difficult to place in either C. wootonii or C. yavapensis. T. Reeves (1979) identified several specimens from Arizona that he hypothesized were hybrids between C. wootonii and C. fendleri.
