Habit | Plants perennial, rhizomatous; caudex thick, with many rhizomatous, creeping, branched, slender subterranean shoots, terminating in tight tufts of leaves and erect flowering stems. | Plants perennial, grayish white-tomentose, eglandular; taproot slender to stout; caudex branched, slightly woody. |
Stems | simple, 5–15 cm, pubescent and viscid, with stipitate glands. |
several, erect, branched distally, stout, 40–100 cm. |
Leaves | 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. |
basal blade oblanceolate, spatulate, 5–10 cm × 10–25(–30) mm, margins entire, apex acute, apiculate, with tuft of white hairs; cauline in 5–10 pairs, sessile, reduced distally, blade with both surfaces obscured by dense, silky, grayish-white tomentum. |
Inflorescences | usually with solitary terminal flower, sometimes cymose, to 8-flowered, open. |
with 1–several dichotomies, several-flowered, open, bracteate; branches ascending, elongate; bracts leaflike, 10–20 mm. |
Pedicels | erect or angled near tip with flowers slightly nodding, 1–3 times longer than calyx, glandular-puberulent, often densely so. |
straight, stout, to 10 cm. |
Flowers | 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. |
ca. 35 mm; calyx thickly 10-veined, obovate, ca. 15 × 10 mm in fruit, margins dentate with 5 narrowly lanceolate lobes ca. 1/4 length of tube, tomentose; corolla rich magenta-pink, sometimes white, clawed, claw equaling calyx, limb spreading horizontally, broadly obovate, shallowly 2-lobed, appendages 2, narrow, 2–4 mm; stamens equaling claw; stigmas 5, equaling claw. |
Capsules | equaling calyx, opening by 6 (or 8 or 10) lanceolate teeth; carpophore 1–2.5 mm. |
equaling to tightly enclosed within calyx, obovate-elliptic, ca. 14 mm, opening by 5 spreading, lanceolate teeth; carpophore ca. 2 mm. |
Seeds | brown, broadly reniform, flattened, 2–2.5 mm, rugose, more coarsely so on margins. |
grayish brown, reniform-rotund, plump, 1–1.5 mm, coarsely verrucate. |

Discussion | Of conservation concern. 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 Nevada population, which is the basis for the name Silene clokeyi, is interfertile (A. R. Kruckeberg 1961) with populations in Utah (the basis for the name S. petersonii). Accordingly, a single species is recognized here without infraspecific taxa. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
