Habit | Plants perennial; taproot slender. | Plants perennial; taproot stout, fleshy. |
Stems | ascending, decumbent at base, branched, shortly rhizomatous, to 80 cm, softly pubescent, ± glandular, at least distally, rarely subglabrous. |
several, erect, simple proximal to inflorescence, 50–160 cm, glabrous to sparsely retrorse-puberulent proximally, more densely so and glandular distally. |
Leaves | sessile at mid and distal stem, petiolate to spatulate proximally; petiole equaling or longer than blade of basal leaves; blade ovate to elliptic, 3–13 cm × 10–50 mm (not including petiole), apex acute to acuminate, sparingly pubescent, densely so on abaxial midrib. |
withered towards base at anthesis, in 10–20 pairs, sessile, gradually reduced distally; blade 3-veined, lanceolate to ovate, rounded into base, 4–12 cm × 20–50 mm, apex acute, not acuminate, glabrous to scabrous-puberulent adaxially, scabrous-puberulent abaxially. |
Inflorescences | dichasial cymes, several- to many-flowered, open, bracteate; bracts lanceolate, 4–20 × 2–7 mm, herbaceous, softly hairy throughout with long-septate hairs, not glandular, or with some glandular hairs. |
terminal, cymose, compound, many-flowered, bracteate, pedunculate, 15–25(–30) × 5–10 cm; bracts lanceolate, 3–30 mm; peduncle ascending. |
Pedicels | ascending, 0.2–3 cm, usually shorter than calyx. |
1–4 times longer than calyx, stipitate-glandular, puberulent. |
Flowers | unisexual, some plants having only staminate flowers, others having only pistillate flowers, 20–25 mm diam.; calyx 8–12-veined, campanulate, narrowly so in staminate flowers, broadly in pistillate, 10–15 × to 7 mm in flower, 11 mm broad in fruit, herbaceous, margins dentate, softly pubescent, lobes 5, erect, lanceolate, 2–3 mm; petals bright pink, clawed, claw equaling or longer than calyx, limb spreading horizontally, broadly obovate, unlobed or 2-lobed, to 12 × 12 mm, appendages 4, ca. 1 mm; stamens and stigmas equaling petal claw; styles 5. |
calyx prominently 10-veined, tubular in flower, 18–25 × 3–4 mm, swelling in middle to 6–9 mm in fruit, umbilicate, constricted near base around carpophore, glandular-pubescent, especially on veins, veins green, lobes 2–4 mm, midrib lanceolate, margins often red tinged, broad, membranous; corolla scarlet, clawed, claw equaling calyx, limb oblong to elliptic, unlobed, rarely emarginate or shallowly 2-lobed, 10–20 × 5–6 mm, apex rounded, appendages 2, tubular, 2–4 mm; stamens exserted; styles 3(–5), exserted. |
Capsules | broadly ovoid to globose, equaling and often splitting calyx, opening by 5 (splitting into 10) revolute teeth; carpophore absent. |
ovoid-ellipsoid, narrowed at both ends, equaling calyx, opening by 6 (or 8 or 10) ascending teeth; carpophore 3–5 mm. |
Seeds | dark brown to black, broadly reniform, plump, 1–1.6 mm, densely and evenly papillate. |
dark reddish brown, reniform, 1.5–2 mm, with smooth and glossy, flat or concave sides, margins angled, shallowly rugose. |

Discussion | Silene dioica is closely related to S. latifolia and completely interfertile with it. The two species hybridize wherever they grow in close proximity, and the offspring (S. hampeana Meusel & K. Werner) usually have pale pink flowers. Silene dioica and S. latifolia are difficult to separate in herbarium material unless flower color has been noted. The characters that distinguish S. dioica are the usually dense, long, and soft pubescence covering at least the distal portion of the plant; the broad, almost globose, thin, and brittle capsule with revolute teeth; and the softer, thinner, usually broader leaves. Occasionally, double-flowered plants are encountered as garden escapes. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Silene regia is a very distinct, spectacular species with tall stems, a narrow, many-flowered inflorescence, and bright red petals. It is probably related to S. laciniata via S. subciliata. Silene regia is in the Center for Plant Conservation’s National Collection of Endangered Plants. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
