erect, branched, rarely simple, 15–45 cm, with long, often crinkled hairs mixed with short pubescence, viscid-glandular distally. |
Leaves | mostly basal, densely tufted; basal numerous, pseudopetiolate, blade narrowly oblanceolate, tapering into base, 0.5–3 cm × 1.5–4 mm, ± fleshy, apex acute, puberulent; cauline in 1–3 pairs, ± sessile, reduced, blade narrowly oblanceolate to linear-lanceolate, 0.7–2 cm × 1–3 mm, apex acute, puberulent. |

Inflorescences | flowers terminal, solitary, or in single dichotomy, bracteate; bracts leaflike, 3–15 mm. |
open, with racemose branches, internodes and bracts usually ca. equaling fruiting calyx, 1–5 mm, longer proximally. |
Pedicels | erect, ca. equaling calyx, viscid glandular-pubescent, hairs with purple septa. |
|
Flowers | calyx prominently 10-veined, campanulate, not contracted proximally around carpophore, 10–15 × 5–7 mm, papery, veins parallel, purplish, with pale commissures, with purple-septate glandular hairs (rarely septa not purple), lobes ovate, ca. 2 mm, margins broad, membranous, apex obtuse; corolla off-white or tinged with dusky purple, clawed, claw equaling calyx, broadened distally, limb 2-lobed, 3–5 mm, appendages ca. 1 mm; stamens equaling calyx; styles 3(–4), equaling calyx. |
5–8 mm diam.; calyx prominently 10-veined, narrowly tubular-ovoid in flower, ovoid in fruit, constricted at mouth, 7–10 × 3–5 mm, membranous between veins, margins dentate, hispid, hairs ca. 2 mm, veins parallel, lobes lanceolate, 2–2.5 mm, apex greenish purple, acute; petals white or pink, often with dark spot or dark pink throughout, clawed, claw equaling calyx, limb elliptic to obovate, lobed or unlobed, to 6 mm, appendages 2, oblong to narrowly lanceolate, 1–1.5 mm; stamens equaling or shorter than calyx; stigmas 3, included in calyx. |
Capsules | equaling calyx, opening by 6 (or 8) teeth; carpophore 2.5–3.5 mm. |
equaling calyx, opening with 6 recurved, narrowly triangular teeth; carpophore shorter than 1 mm, pubescent. |
Seeds | brown, broadly winged, reniform, 1–2 mm, rugose-tessellate. |
dark reddish brown, reniform, angular with concave, radially ridged faces, broad outer edge transversely ridged and verrucose, ca. 0.5 mm broad. |

Discussion | Silene suksdorfii appears to be closely related to S. parryi but differs in its broadly winged seeds, smaller size, cespitose habit, and the prominent purple-septate hairs of the calyx, although the latter occasionally are present in S. parryi. It is very similar to, and in Idaho appears to intergrade with, another alpine species, S. sargentii, which has linear leaves and lacks the purple septa in the hairs and the broad wing on the seeds. It is similar also to S. hitchguirei; see discussion under that species. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
