Silene armeria L. (1753)

Nile region (Cairo) and Mediterranean region.

South, East and  Central Europe, Egypt, Northwest Asia.

The long-tubular, clavate calyx enclosing the unusually long carpophore helps to distinguish Silene armeria. It is an occasional and adventive garden escape.

Plants annual, glabrous through-out, ± glaucous, some-times glu-tinous in distal parts; taproot slender. Stems simple, branched in inflorescence, (10-)20-40(-70) cm. Leaves: basal withering be-fore flowering, blade lanceolate-spatulate, 2-5 cm; cauline sessile to amplexicaulous, blade lanceolate to ovate or elliptic, 1-6 cm × 5-25 mm, apex acute. Inflorescences cymose, bracteate; cyme capitate or with flowers clustered at end of slender branches; bracts lanceolate-acicular, 2-10 mm. Pedicels 0.1-0.5 cm. Flowers: calyx usually purple tinged, 10-veined, elongate, clavate, lobed, constricted proximally into narrow tube, 13-17 × 2.5-4 mm, rather mem-branous; lobes ovate-triangular, ca. 1 mm, apex obtuse; petals pink (rarely white), unlobed, limb obovate, ca. 5 mm, base cuneate into claw 6-8 mm, auricles absent, appendages linear to lanceolate, 2-3 mm, apex acute; stamens slightly longer than petal claws; styles 3(-4), exserted. Capsules oblong, 7-10 mm, opening by 6 (or 8) spreading teeth; carpophore 7-8 mm, glabrous. Seeds dark brown, reniform-rotund, less than 1 mm diam., rugose. 2n = 24 (Europe).
