Plants annual; taproot slender. Stems erect, simple or branched, 20–65 cm, glandular-pubescent. Leaves: proximal forming rosette, blade oblanceolate, spatulate, 3–8(–12) cm × 5–13(–25) mm, apex ± obtuse, sparingly pubescent and glandular; cauline reduced distally, blade lanceolate, 1–7 cm × 2–15 mm, apex ± acute, sparingly pubescent and glandular. Inflorescences dichasiate, open, bracteate; bracts leaflike, to 15 mm. Pedicels ascending, 1–3(–5) cm, densely glandular-pubescent, viscid. Flowers: calyx prominently 20–25-veined, ovate-conic, 8–12 mm, margins dentate, coarsely pubescent, glandular, lobes erect, narrowly lanceolate, 2–3 mm, margins membranous ca. 1/4 length of calyx; corolla inconspicuous, cream, purple tinged adaxially, dull orange abaxially, equaling or slightly longer than calyx, limb ovate, 1–3 mm, apex notched, appendages absent, auricles round, small; stamens shorter than corolla; stigmas 3, shorter than corolla. Capsules tightly enclosed in calyx, ovoid, with narrow opening, opening by 6 triangular teeth ca. 1 mm; carpophore ca. 1 mm. Seeds dark brown to black, rotund, 0.6–1 mm broad, papillate. 2n = 20 (Asia).
Phenology: Flowering spring–early summer.
Habitat: Open places, oak parklands, especially after burning

Discussion
Silene coniflora apparently was introduced into North America in the early days of European exploration and settlement of the Pacific coast. It occurs as a native species from the eastern shores of the Mediterranean to Pakistan and Afghanistan. The report by C. V. Piper (1906) of its occurrence in Washington is based on a specimen of S. conica. I have been unable to confirm the statement by M. E. Peck (1961) that S. multinervia is “sparingly introduced” along the coast of Oregon.
