Habit | Plants perennial, viscid; taproot stout; caudex branched, woody, producing several to many shoots. | Plants annual; taproot slender. |
Stems | erect, branched, leafy, 20–60 cm, villose-tomentose, viscid-glandular. |
erect, simple or branched, slender, to 80 cm, subglabrous to retrorsely puberulent especially proximally, distal internodes frequently glutinous. |
Leaves | 2 per node, connate proximally, sessile, largest in mid stem; blade lanceolate, 3–7 cm × 5–15 mm, apex acute, glandular-tomentose throughout. |
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. |
Inflorescences | open, leafy cymes, bracteate, viscid and glandular-tomentose, branches ascending, mostly floriferous, flowers terminal and at distal nodes; bracts leaflike, 5–30 mm. |
cymose, open, branches usually ascending, several- to many-flowered, 1-flowered in depauperate specimens. |
Pedicels | shorter than calyx. |
|
Flowers | calyx obscurely 10-veined, tubular-campanulate, 10–15 × 4–5 mm in flower, becoming clavate and 15–20 × 6–8 mm in fruit, narrowed toward base around carpophore, herbaceous, viscid-pubescent, veins more distinct at base, without conspicuous pale commissures, lobes narrowly lanceolate, 3–6 mm, margins very narrow, membranous, apex blunt; corolla greenish white, clawed, claw equaling calyx, widened distally, limb emarginate, 2 × 4 mm, appendages 4(–6), ca. 0.5 mm; stamens equaling petals; styles 3, equaling petals. |
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. |
Capsules | ellipsoid, slightly longer than calyx, opening by 6 teeth; carpophore 1.5–2.5 mm. |
equaling calyx, opening by 6 teeth; carpophore less than 1 mm. |
Seeds | yellowish brown, winged, reniform, ca. 2 mm, rugose; wing broad, wrinkled. |
dull gray-black, reniform, 0.5–0.8 mm diam., finely papillate. |

Discussion | Of conservation concern. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.) |
