Habit | Plants perennial; taproot stout, fleshy; caudex branched. | Plants perennial; taproot stout; caudex much-branched, woody. |
Stems | several, straggling to erect, freely branched, 2–7 cm, pilose and glandular, sparsely so proximally. |
|
Flowering stems | erect, with 3–6 pairs of leaves below inflorescence, 30–80 cm, short-pubescent, glandular and somewhat viscid distally. |
|
Leaves | basal leaves withered at time of flowering, distal sessile, proximal petiolate, largest on mid to distal stem; blade subrotund to broadly ovate-lanceolate, 3–10 cm × 20–70 mm, base cuneate into petiole, apex short-acuminate, sparsely short-pilose. |
proximal petiolate, blade oblanceolate, 3–6(–8) cm × 5–15 mm (including petiole), base tapered into short petiole, apex acute to obtuse and apiculate, short-pubescent on both surfaces, pubescence rather sparse adaxially; cauline leaves sessile, blade elliptic-lanceolate, 2–6 cm × 5–15 mm. |
Inflorescences | cymose, open, few-flowered, leafy, bracteate; bracts resembling distal leaves. |
branched, several–many-flowered, open, bracteate, flowering portion to 15 cm and ca. 1/2 as broad, glandular and viscid; cymules usually 1–3-flowered; bracts narrowly lanceolate, shorter than pedicel; peduncle shorter than internodes. |
Pedicels | 1–3(–4) cm, viscid, with long septate-glandular hairs. |
divaricate, sharply bent distally, 5–15 mm. |
Flowers | calyx indistinctly veined, tubular, broadened distally, constricted towards base around carpophore, ± umbilicate, 20–25 × 5–8 mm, herbaceous, glandular-pilose, lobes triangular, 3–4 mm, margins narrow, membranous, ciliate; corolla scarlet, clawed, claw equaling calyx, limb deeply 2-lobed, 10–15 mm, lobes lanceolate, sometimes with 2 smaller lateral teeth, ciliate, appendages saccate, 1–1.5 mm, with clear area abaxially; stamens shortly exserted; styles 3, shortly exserted. |
nodding; calyx prominently 10-veined, tubular to campanulate, umbilicate but narrowed at base, lobed, 9–11 × 3–5 mm in flower, in fruit ovate to turbinate, 5–8 mm broad, viscid-pubescent, veins parallel, green, papery between; lobes 5, narrowly lanceolate, obtuse, 2–3 mm, ciliate; corolla ± white, often greenish abaxially and pink tinged, 2 times calyx; petals 2-lobed, margins entire to erose, appendages linear, narrow, 1–2.5 mm; stamens often long-exserted; filaments pubescent at base; styles persistent, 3, long-exserted, filamentous, exceeding 2 times calyx. |
Capsules | narrowly ellipsoid, not distending calyx, included within it, opening by 6 teeth; carpophore 6–8 mm. |
broadly ovoid, ca. equaling calyx, opening by 6 ascending, triangular teeth; carpophore 2–3 mm. |
Seeds | gray, broadly reniform, plump, ca. 1 mm, shallowly papillate. |

Discussion | Silene rotundifolia is clearly related to S. laciniata but is a well-marked species of the deciduous forest region. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Silene bridgesii is similar to S. lemmonii but usually can be distinguished by its larger size, broader and larger leaves, the near-absence of sterile basal shoots, and larger floral parts and fruits. Although S. longistylis has often been cited as a synonym of S. lemmonii, examination of the holotype (Henderson s.n., GH) indicates that it is referable to S. bridgesii. Silene bridgesii is found in the Sierra Nevada and southern Cascades. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
