--><span class="statement" id="st-undefined" data-properties=""><b>Stems </b>long-creeping, cordlike, internodes 1–2(–4) cm, old petiole bases few, hairs absent; scales usually tan to light brown, ovate-lanceolate, radial walls tan to brown, thin, luminae tan. <b>Leaves</b> monomorphic, at stem apex but not tightly clustered, to 45 cm, sori production about equal on all leaves (fairly independent of season). <b>Petiole</b> dark brown to black at base, gradually becoming green or straw-colored distally, (1–)2–3 times length of blades, sparsely scaly throughout. <b>Blade</b> elongate-pentagonal, 3(–4)-pinnate-pinnatifid; rachis and costae lacking gland-tipped hairs or bulblets; axils of pinnae with occasional multicellular gland-tipped hairs. <b>Pinnae</b> ascending, typically at acute angle to rachis, only proximal pinnae occasionally curving toward blade apex, margins serrate; proximal pinnae pinnate-pinnatifid, inequilateral, basal basiscopic pinnule stalked, enlarged, base truncate to obtuse; distal pinnae deltate to ovate. <b>Veins</b> directed into notches. <b>Indusia</b> cup-shaped, apex truncate, hairs gland-tipped only along margin. <b>Spores</b> spiny, usually 37–42 µm. <b>2n</b> = 168.</span><!--

|discussion=<p><i>Cystopteris montana</i>, the most distinctive of the <i>Cystopteris</i> in the flora, probably is allied to Asian species. Although this boreal species is restricted primarily to high latitudes, it occurs disjunctly at high elevations in Colorado, where its habitats are being threatened by development. <i>Cystopteris montana</i> does not hybridize with any other <i>Cystopteris</i> in the flora, but it has been implicated in the origin of the European allopolyploid <i>C. alpina</i> (Roth) Desvaux.</p>
