Habit | Plants annual; taproot slender. | Plants perennial, rhizomatous; rhizome creeping. |
Stems | erect, simple or branched, slender, to 80 cm, subglabrous to retrorsely puberulent especially proximally, distal internodes frequently glutinous. |
erect, usually simple, 30–150 cm, with short, dense, eglandular pubescence, sparsely so toward base. |
Leaves | 2 per node; blade with margins ciliate toward base, apex acute to obtuse; basal blades oblanceolate, spatulate; cauline narrowly oblanceolate to linear, 1–9 cm × 2–15 mm, scabrous or puberulent, rarely glabrous on both surfaces. |
sessile, 2 per node; blade prominently 3–5-veined, ovate-acuminate, round at base, (4–)6–10(–13) cm × (20–)30–50(–90) mm, appressed-pubescent on both surfaces. |
Inflorescences | cymose, open, branches usually ascending, several- to many-flowered, 1-flowered in depauperate specimens. |
paniculate, narrow, many-flowered, open, bracteate, pedunculate, 10–50 × 3–5 cm, densely puberulent; bracts narrowly lanceolate, 3–15 mm, apex acuminate; peduncle ascending. |
Pedicels | ascending, recurved near apex, ca. equaling calyx. |
|
Flowers | mature calyx prominently 10-veined, campanulate to ovate, 5–9 × 3–5 mm, margins dentate, glabrous, veins parallel, with pale commissures; lobes usually purple, triangular, acute, ca. 1 mm; petals white, often suffused with dark red, rarely wholly dark red, limb ovate, usually 2-lobed, ca. 2.5 mm, slightly longer than calyx, rarely petals absent, claw narrow, appendages 0.1–0.4 mm; stamens included; styles 3; stigmas included. |
nocturnal; calyx prominently 10-veined, tubular to narrowly campanulate and 6–9 × 3–4 mm in flower, turbinate and 10–12 × 4–5 mm in fruit, narrowed proximally around carpophore, veins parallel, green, broad, with pale commissures, puberulent, sometimes with few glands, lobes triangular-acute, 2–3 mm; corolla white, clawed, claw equaling calyx, broadened into limb, limb obtriangular, deeply lobed, 7–9 mm, lobes ca. 8, linear, appendages minute; stamens slightly longer than corolla; styles 3, ca. 2 times as long as corolla. |
Capsules | equaling calyx, opening by 6 teeth; carpophore less than 1 mm. |
narrowly ovoid, slightly longer than calyx, opening by 3 (splitting into 6) ascending teeth; carpophore 2–2.5 mm. |
Seeds | dull gray-black, reniform, 0.5–0.8 mm diam., finely papillate. |
dark brown, reniform, 0.8–1.5 mm, shallowly tuberculate. |

Discussion | The six varieties and forms of Silene antirrhina noted above were named on the basis of stature and flower color, but none appear to be worthy of recognition. The species is very plastic, being greatly affected by moisture, exposure, and nutrients. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Of conservation concern. Silene ovata is a very distinctive species with large, ovate, acuminate, sessile, paired leaves, and very narrowly lobed white petals. The flowers open at night and are moth-pollinated. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
