Habit | Plants perennial, rhizomatous; rhizome creeping. | Plants perennial, cespitose; tap-root stout; caudex with many often subterranean branches, woody. |
Stems | erect, usually simple, 30–150 cm, with short, dense, eglandular pubescence, sparsely so toward base. |
ascending, branched, wiry, leafy, slender, 10–20 cm, finely retrorse gray-puberulent. |
Leaves | 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. |
largest in mid-stem region; blade linear to narrowly lanceolate or oblanceolate, 1–4 cm × 1–5 mm, apex sharply acuminate, glandular-puberulent. |
Inflorescences | paniculate, narrow, many-flowered, open, bracteate, pedunculate, 10–50 × 3–5 cm, densely puberulent; bracts narrowly lanceolate, 3–15 mm, apex acuminate; peduncle ascending. |
with flowers usually solitary, terminal on branches. |
Pedicels | ascending, recurved near apex, ca. equaling calyx. |
shorter than calyx, glandular-puberulent. |
Flowers | 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. |
calyx 10-veined, tubular, constricted around carpophore, umbilicate, 20–30 × 3–6 mm, papery, green, glandular-puberulent, lobes lanceolate, 2–4 mm, margins membranous, apex acute; corolla scarlet, clawed, claw equaling calyx, limb obconic, 2-lobed, 7–10 mm, margins entire or crenate, appendages ± lacerate, 1–1.5 mm; stamens exserted, ± equaling corolla lobes; styles 3, exserted, ± equaling corolla lobes. |
Capsules | narrowly ovoid, slightly longer than calyx, opening by 3 (splitting into 6) ascending teeth; carpophore 2–2.5 mm. |

Discussion | 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.) |
Of conservation concern. Silene plankii is a close relative of S. laciniata, differing in its compact tufted growth, small and narrow leaves, and shallowly two-lobed petals. It is endemic to the Del Carmen Mountains on either side of the Rio Grande valley. Plants of S. laciniata with a habit and leaves similar to S. plankii but the deeply laciniate petals of S. laciniata occur on the cliffs of Santa Cruz Island off the coast of California.
