--><span class="statement" id="st-undefined" data-properties=""><b>Stems </b>short-creeping to compact, 3–7 mm diam.; scales uniformly brown or slightly darker at base, linear-lanceolate, straight to slightly contorted, loosely appressed, persistent. <b>Leaves</b> clustered, 6–50 cm; vernation noncircinate. <b>Petiole</b> black, rounded adaxially. <b>Blade</b> lanceolate to linear-oblong, 2-pinnate to 2-pinnate-pinnatifid at base, 1–7 cm wide; rachis rounded adaxially, lacking scales, with dimorphic pubescence, abaxially sparsely hirsute, adaxially covered with tortuous, appressed hairs. <b>Pinnae</b> not articulate, dark color of stalk continuing into pinna base, basal pair slightly smaller than adjacent pair, ± equilateral, appearing glabrous or sparsely pubescent adaxially. <b>Costae</b> green adaxially for most of length; abaxial scales absent. <b>Ultimate</b> segments narrowly elliptic to elongate-deltate, not beadlike, the largest 3–7 mm, abaxially and adaxially sparsely hirsute to glabrescent. <b>False</b> indusia marginal to obscurely inframarginal, somewhat differentiated, 0.1–0.4 mm wide. <b>Sori</b> ± continuous around segment margins. <b>Sporangia</b> containing 32 spores. n = 2n = 87, apogamous.</span><!--

|discussion=<p>Plants of <i>Cheilanthes alabamensis</i> occurring in the flora are apogamous triploids; a sexual diploid cytotype has been found in Nuevo León, Mexico (M. D. Windham, unpublished). Given the high degree of morphologic similarity between the two cytotypes, the North American triploid probably was derived from the Mexican diploid through autopolyploidy. In the flora, <i>Cheilanthes alabamensis</i> is most often confused with <i>C. microphylla</i>, from which it is distinguished by having thicker stems, mostly green costae, and 32-spored sporangia.</p>
