--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>on rock. <b>Stems</b> decumbent to erect, or creeping, few to many branched; scales colorless or brownish, concolored or bicolored, ovate, lanceolate or linear, margins entire. <b>Leaves</b> dimorphic, scattered or densely tufted; fertile leaves 5–25 cm; sterile leaves 3–20 cm, shorter than fertile leaves. <b>Petiole</b> dark brown proximally, light brown to green distally, with single longitudinal groove adaxially, scaly, with single vascular bundle. <b>Blade</b> deltate, lanceolate to elliptic, 2–4-pinnate, somewhat leathery or herbaceous to membranaceous, abaxially glabrous, adaxially glabrous or sparsely pubescent, dull to somewhat lustrous, not striate; rachis straight. <b>Ultimate</b> segments of blade short-stalked or sessile, free or adnate to midrib; stalks dull, green; segments of sterile leaves ovate, elliptic, obovate, or fan-shaped, usually less than 4 mm wide, margins plane, dentate or shallowly to deeply cut; fertile segments strongly differentiated from sterile segments, lanceolate to linear, usually less than 2 mm wide, margins reflexed to form false indusia extending over entire length of segments, at first covering young sporangia, often becoming plane at maturity. <b>Veins</b> of ultimate segments usually obscure, free, pinnately branched and divergent distally. <b>False</b> indusia greenish to brown, broad, clearly marginal, usually concealing sporangia. <b>Sporangia</b> scattered along veins on abaxial leaf surface, often intermixed with farina-producing glands, containing 64 spores. <b>Spores</b> yellow, tetrahedral, trilete, verrucose, equatorial flange absent. <b>Gametophytes</b> glabrous. <b>x</b> = 30.</span><!--
