Habit | Plants annual; taproot slender. | Plants perennial; taproot thick; caudex erect, branched, thick and woody, producing tufts of leaves. |
Stems | erect, branched, rarely simple, 15–45 cm, with long, often crinkled hairs mixed with short pubescence, viscid-glandular distally. |
erect, branched distally, with 2–4 pairs of reduced leaves, 15–50 cm; flowering shoots usually subscapose, coarsely pubescent with hairs colorless, septate, and long, viscid-glandular, especially distally. |
Leaves | 2 per node, blade with coarse, ascending, scabrous pubescence on both surfaces; basal few, withering, blade oblanceolate to spatulate-petiolate, 0.5–5 cm × 3–15 mm; cauline blades oblanceolate to lanceolate, 1–7 cm × 1–15 mm, apex obtuse or shortly acuminate to acute. |
mostly basal; basal long-petiolate, blade oblanceolate to elliptic, 6–15 cm × 10–30 mm, narrowed to base, not fleshy; cauline few, sessile, reduced distally, blade lanceolate, 0.8–4 cm × 3–8 mm, not fleshy. |
Inflorescences | open, with racemose branches, internodes and bracts usually ca. equaling fruiting calyx, 1–5 mm, longer proximally. |
thyrsate, subscapose, rarely simple, (3–)5–12(rarely more)-flowered, open, bracteate, bracteolate, densely pubescent, glandular, viscid; alternate branches often suppressed or developing unevenly; proximal nodes often with single flower; bracts and bracteoles resembling stem leaves but much reduced. |
Pedicels | 1/4–2 times length of calyx. |
|
Flowers | 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. |
calyx prominently 10-veined, veins parallel, those of lobes broadened distally, tubular in flower, 10–13 × 2.5–4 mm, campanulate-ovate in fruit, broadest near middle and contracted towards mouth, not contracted proximally, 12–18 × 5–8 mm, with pale commissures, lobes 5, erect, narrowly lanceolate, 4–6 mm, margins narrow, membranous proximally, apex blunt, with glandular hairs; petals 11/2–2 times longer than calyx tube; corolla pink, clawed, claw equaling calyx tube, limb obovate, deeply 2-lobed, 5–10 mm, appendages 2, linear, ca. 1.5 mm; stamens exserted, shorter than petals; styles 3–5, included in calyx, ± equaling calyx or corolla. |
Capsules | equaling calyx, opening with 6 recurved, narrowly triangular teeth; carpophore shorter than 1 mm, pubescent. |
conic to ellipsoid, equaling calyx lobes, opening by 6–10 recurved teeth; carpophore 1–2 mm. |
Seeds | dark reddish brown, reniform, angular with concave, radially ridged faces, broad outer edge transversely ridged and verrucose, ca. 0.5 mm broad. |
dark brown, reniform, 1–1.5 mm, prominently papillate; papillae larger around margins. |

Discussion | Silene nuda may be confused with the other scapose species, S. scaposa, but S. nuda has larger, more conspicuous petals that are one and one-half to two times as long as the calyx tube. It is found in the Sierra Nevada and southern Cascades. The Nevada populations tend to grow in drier situations and on saline flats.
