--><span class="statement" id="st-undefined" data-properties=""><b>Stems </b>short-creeping, usually 3–7 mm diam.; scales usually bicolored, with broad, well-defined, dark, central stripe and narrow, light brown margins, linear-lanceolate, straight to slightly contorted, strongly appressed, persistent. <b>Leaves</b> clustered, 4–25 cm; vernation noncircinate. <b>Petiole</b> dark brown, rounded adaxially. <b>Blade</b> lanceolate to ovate-deltate, usually 3-pinnate at base, 1–4 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 to sparsely pubescent adaxially. <b>Costae</b> green adaxially for most of length; abaxial scales multiseriate, ovate-lanceolate, deeply cordate at base, with overlapping basal lobes, conspicuous, the longest 0.4–1 mm wide, imbricate, often concealing ultimate segments, long-ciliate, cilia usually confined to proximal 1/2. <b>Ultimate</b> segments oblong to ovate, beadlike, the largest 1–3 mm, abaxially densely covered with branched hairs and small, ciliate scales, adaxially with scattered branched hairs or glabrescent. <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>Preliminary isozyme analyses support D. B. Lellinger's (1985) suggestion that <i>Cheilanthes intertexta</i> is a fertile allotetraploid hybrid between <i>C. gracillima</i> and <i>C. covillei</i>. It is morphologically most similar to the latter parent (see comments under <i>C. covillei</i>), but it is occasionally confused with <i>C. gracillima</i>, with which it apparently hybridizes to form sterile intermediates that have been called <i>C. gracillima</i> <i></i></i>var.<i><i> aberrans</i> M. E. Jones. <i>Cheilanthes intertexta</i> may also be confused with <i>C. clevelandii</i>, with which it is partially sympatric. In addition to the characters given in the key, <i>C. intertexta</i> is distinguished from closely related sexual species by having larger spores averaging more than 55 µm in diameter.</p>
