Woodsia scopulina shows substantial variation in leaf size, shape, and dissection, and in the abundance of multicellular hairs on the pinnae. Although much of this variation seems to be environmentally induced, recent studies (M. D. Windham 1993) have identified three chromosomal/morphologic variants that are treated here as subspecies. Diploid populations of W . scopulina are divisible into two groups, one of which (subsp. scopulina ) is scattered throughout the mountainous regions of western North America while the other (subsp. appalachiana ) is confined to montane habitats in the southeastern United States. These taxa seem amply distinct (T. M. C. Taylor 1947) and might be considered separate species if not for the existence of populations in the Great Lakes region and western cordillera that tend to bridge the morphologic and geographic gap between them. These intermediate populations (subsp. laurentiana ) appear to be uniformly tetraploid and may have arisen through ancient hybridization between subsp. scopulina and subsp. appalachiana . In regions where subsp. laurentiana is sympatric with subsp. scopulina , the two taxa are rarely found growing together, suggesting that they differ in their ecological tolerances and/or habitat requirements.

Stems compact, erect to ascending, with few to many persistent petiole bases of unequal lengths; scales uniformly brown or bicolored with dark central stripe and pale brown margins, ovate to narrowly lanceolate. Leaves 9--35 × 1--8 cm. Petiole usually reddish brown to dark purple proximally when mature, not articulate above base, relatively brittle and easily shattered. Blade lanceolate to linear-lanceolate, 2-pinnate proximally, moderately glandular, rarely somewhat viscid; most glandular hairs with thick stalks and distinctly bulbous tips; rachis usually with abundant glandular and nonglandular hairs. Pinnae lanceolate-deltate to ovate, longer than wide, abruptly tapered to a rounded or broadly acute apex, occasionally attenuate; largest pinnae with 5--14 pairs of pinnules; abaxial and adaxial surfaces glandular and sparsely villous, with flattened, multicellular hairs concentrated along midribs. Pinnules dentate, often shallowly lobed; margins nonlustrous, thin, slightly glandular and occasionally ciliate with isolated, multicellular hairs, lacking translucent projections. Vein tips slightly (if at all) enlarged, barely visible adaxially. Indusia of filamentous or nonfilamentous segments, these multiseriate proximally, often uniseriate distally, composed of ± isodiametric cells, concealed by or slightly surpassing mature sporangia. Spores averaging 39--57 µm.

Woodsia scopulina, common name Rocky Mountain woodsia, is a deciduous perennial fern in the family Woodsiaceae.
This plant is native to the western and northern United States and Canada. W. scopulina is a small to medium sized fern, 10-30 centimeters high, which grows in mesic to dry rock crevices.[2][3]
Description
Woodsia scopulina has twice pinnate fronds arising from a short scaly rhizome. The mostly upright fronds are 10–30 cm in length and up to 8 cm in width and are medium to pale green in color. The pinnae and rachis are sparsely to moderately covered with long hairs that protrude sharply (not appressed to stem), some with a globular gland at the tip. The rachis is grooved on top (adaxially). Small round sori on the underside of pinnae are initially partly covered with a narrowly lobed indusium. New leaves show circinate vernation (tightly curled).[4][3]
Range
Woodsia scopulina is widespread in mountains near the west coast of North America from southern Alaska to southern California, and in the Rocky Mountains from British Columbia to Colorado. There are also isolated populations in northeastern North America.[4]
Habitat
Woodsia scopulina is commonly found in sunny rocky habitats including rock crevices, talus slopes, and rock ledges.[3]
