--><span class="statement" id="st-undefined" data-properties=""><b>Stems </b>usually short-creeping, 1–3 mm diam.; scales usually bicolored, with well-defined, dark, central stripe and broad, light brown margins, lanceolate, straight to slightly contorted, strongly appressed, persistent. <b>Leaves</b> clustered to somewhat scattered, 8–40 cm; vernation noncircinate. <b>Petiole</b> dark to light brown, rounded adaxially. <b>Blade</b> oblong-lanceolate to ovate, usually 4-pinnate at base, 2–8 cm wide; rachis rounded adaxially, with scattered scales and sparse monomorphic pubescence. <b>Pinnae</b> not articulate, dark color of stalk continuing into pinna base, basal pair not conspicuously larger than adjacent pair, usually equilateral, appearing glabrous adaxially. <b>Costae</b> green adaxially for most of length; abaxial scales multiseriate, ovate-lanceolate, deeply cordate at base, with overlapping basal lobes, conspicuous, 0.4–1 mm wide, imbricate, occasionally concealing ultimate segments, ciliate (usually only on proximal 1/2). <b>Ultimate</b> segments round to subcordate, beadlike, the largest 1–2 mm, abaxially with branched hairs and small ciliate scales, adaxially glabrous. <b>False</b> indusia marginal, weakly differentiated, 0.05–0.25 mm wide. <b>Sori</b> ± continuous around segment margins. <b>Sporangia</b> containing 64 spores.</span><!--

|discussion=<p>Although some specimens of <i>Cheilanthes clevelandii</i> can be difficult to distinguish from <i>C. covillei</i> and <i>C. intertexta</i> (see comments under <i>C. covillei</i>), the species is restricted to the coastal mountains of California and Baja California, and it rarely overlaps the ranges of these closely related species. In the region where <i>C. clevelandii</i> is sympatric with <i>C. intertexta</i>, the smaller spores of the former species (averaging less that 55 µm in diameter) are helpful in identification. T. Reeves (1979) tentatively identified two varieties of <i>C. clevelandii</i>, but formal recognition of these taxa must await further study.</p>
