--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>perennial, rhizomatous; caudex thick, with many rhizomatous, creeping, branched, slender subterranean shoots, terminating in tight tufts of leaves and erect flowering stems. <b>Stems</b> simple, 5–15 cm, pubescent and viscid, with stipitate glands. <b>Leaves</b>: basal with blade 1-veined, oblanceolate, broadly spatulate, 1–4 cm × 2–8 mm, apex obtuse to acute, glandular-puberulent throughout, rarely subglabrous adaxially; cauline in 3–6 pairs, sessile, reduced distally, blade lanceolate, narrowly elliptic, or oblanceolate, 2–4 cm × 2–8 mm, apex ± acute, glandular-puberulent throughout. <b>Inflorescences</b> usually with solitary terminal flower, sometimes cymose, to 8-flowered, open. <b>Pedicels</b> erect or angled near tip with flowers slightly nodding, 1–3 times longer than calyx, glandular-puberulent, often densely so. <b>Flowers</b>: calyx prominently 10-veined, campanulate, not contracted proximally around carpophore, 15–20 × 4–8 mm, papery, margins dentate, veins parallel, usually purple tinged, with pale commissures; lobes ovate, 3–5 mm, glandular-puberulent, midrib triangular, margins purple tinged, broad, membranous, apex obtuse; corolla bright pink, clawed, claw equaling calyx, broad and ligulate but abruptly contracted into limb, limb broadly cuneate, shallowly to deeply 2–4-lobed, 5–15 mm, lobes broad or narrow, appendages absent or to 2 mm, margins erose; stamens slightly longer than corolla claw; stigmas 3(–5), slightly longer than corolla claw. <b>Capsules</b> equaling calyx, opening by 6 (or 8 or 10) lanceolate teeth; carpophore 1–2.5 mm. <b>Seeds</b> brown, broadly reniform, flattened, 2–2.5 mm, rugose, more coarsely so on margins. <b>2n</b> = 96.</span><!--

|discussion=<p>Of conservation concern.</p><!--
--><p>This beautiful alpine species is variable with respect to density of pubescence, flower size, and petal structure. As this variation occurs both within and among populations, little useful purpose is served by giving names to it. The <i>Nevada</i> population, which is the basis for the name <i>Silene</i> clokeyi, is interfertile (A. R. Kruckeberg 1961) with populations in Utah (the basis for the name <i>S. petersonii</i>). Accordingly, a single species is recognized here without infraspecific taxa.</p>
