--><span class="statement" id="st-undefined" data-properties=""><b>Stems </b>compact, ascending, stout, 5–10 mm diam.; scales bicolored, linear-subulate, 0.1–0.3 mm wide, centers black, thick, margins brown, thin, erose-dentate. <b>Leaves</b> monomorphic, clustered on stem, 6–40 cm; croziers sparsely villous. <b>Petiole</b> dark brown, lustrous, flattened or slightly grooved adaxially, without prominent articulation lines. <b>Blade</b> linear-oblong, 2-pinnate proximally, 1.5–5 cm wide; rachis brown throughout, straight, shallowly grooved adaxially, usually glabrous. <b>Pinnae</b> perpendicular to rachis or slightly ascending, not decurrent on rachis, usually with 3–9 ultimate segments; costae straight, 2–20 mm, usually shorter than ultimate segments. <b>Ultimate</b> segments narrowly oblong, 5–20 mm, leathery, glabrous; margins recurved on fertile segments, usually covering less than 1/2 abaxial surface, borders whitish, crenulate; apex mucronate. <b>Veins</b> of ultimate segments obscure. <b>Sporangia</b> long-stalked, containing 64 spores, intermixed with sparse farina-producing glands. <b>2n</b> = 116.</span><!--

|discussion=<p>W. H. Wagner Jr. (1965) suggested that <i>Pellaea wrightiana</i> was a fertile allotetraploid hybrid between <i>P. truncata</i> (as P. longimucronata) and <i>P. ternifolia</i>. This hypothesis has been confirmed by isozyme analyses (M. D. Windham 1988). <i>Pellaea wrightiana</i> is therefore treated as a distinct species rather than a variety of <i>P. ternifolia</i>. This tetraploid species hybridizes with <i>P. truncata</i> and <i>P. ternifolia </i>subsp.<i> arizonica</i> to produce sterile triploids and tetraploids with intermediate morphology and malformed spores. <i>Pellaea wrightiana</i> has also hybridized with <i>P. atropurpurea</i> to form a rare apogamous pentaploid known only from western Oklahoma.</p>
