Habit | Plants annual; taproot slender. | Plants perennial; taproot stout; caudex simple or branched, woody, bearing tufts of basal leaves. |
Stems | erect, branched, rarely simple, 15–45 cm, with long, often crinkled hairs mixed with short pubescence, viscid-glandular distally. |
erect, simple proximal to inflorescence, 30–60 cm, softly pubescent and stipitate-glandular. |
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. |
2 per node; basal ± petiolate, petiole ciliate, blade oblanceolate, spatulate, 5–12 cm × 7–20 mm, apex acute, short-pubescent on both surfaces; cauline in 3(–4) pairs, reduced distally, blade oblanceolate to lanceolate. |
Inflorescences | open, with racemose branches, internodes and bracts usually ca. equaling fruiting calyx, 1–5 mm, longer proximally. |
open, narrow, with ascending branches, 9–25-flowered, bracteate, pubescent and stipitate-glandular; bracts narrowly lanceolate, ciliate. |
Pedicels | 1/2–3 times longer than 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, tubular in flower and fruit, umbilicate, somewhat constricted around carpophore, 15–38 × 3–6 mm, papery, sparsely pubescent and stipitate-glandular, veins parallel, green, with pale commissures, lobes 5, broadly ovate, 2–4 mm, scarious around green midrib; corolla pink or rose red (rarely white), clawed, claw equaling calyx, limb oblong, fanlike, deeply 4-lobed, lobes divergent, lanceolate (rarely with only 2 lobes, each with small lateral tooth), (7–)10–20 mm, appendages linear, 2–4 mm; stamens exserted, shorter than petals; stigmas 3, shorter than petals. |
Capsules | equaling calyx, opening with 6 recurved, narrowly triangular teeth; carpophore shorter than 1 mm, pubescent. |
narrowly ovate-elliptic, longer than calyx, opening by 6 recurved teeth; carpophore 4–18 mm. |
Seeds | dark reddish brown, reniform, angular with concave, radially ridged faces, broad outer edge transversely ridged and verrucose, ca. 0.5 mm broad. |
grayish brown, reniform, 1–1.5 mm, verrucate. |

Discussion | The long, tubular calyx and the proportionally long carpophore of Silene occidentalis are remarkable. Plants with the longest calyx tubes (more than 30 mm) have been referred to subsp. longistipitata and appear to be confined to Butte County. Calyx length varies greatly, however, and it is doubtful whether it is a justifiable basis for taxonomic recognition. The deeply lobed pink petals, together with its habit, give S. occidentalis a superficial resemblance to the European S. flos-cuculi, which occurs as an introduction on both sides of the North American continent.
