Description:

Reference: Bengt Oxelman (1995). A revision of the Silene sedoides-group. Willdenowia. 25: 143-169
Stems ascending. Basal leaves (0.5-)1-3(-4) cm long, subglabrous. Cauline leaves spatulate to (narrowly) obovate. Flowers in dichasial cymes passing into monochasia. Hyaline margin of calyx teeth usually with many, sometimes glandular hairs, rarely smooth. Petal limb white to pink, usually emarginate, rarely entire, with a dark spot at base, upright when becoming withered. Coronal scales obliquely triangular, sometimes dentate, white. Anthers white. Capsule twice to several times as long as the gonophore, narrowly ovate, membranous. Gonophore usually swollen when the capsule is mature. Seeds with flat or slightly convex lateral faces and rounded dorsal ridges; testa cells smooth or mamillate. Flowering time: April to July. Ecology: Rocky, stony and sandy places in the maritime supralitoral zone, rarely above this zone, and then as a ruderal plant.

Stems 1-4(-12) cm long. Leaves succulent. Uppermost stem internode 1-2 times as long as subtending leaves. Flowers in cymes with dichasial branching in the lower 1-2 orders, then passing into monochasia. Lowest internodes of inflorescence 0.7-2.5 times as long as lowermost pedicel. Pedicels 5-7(-25) mm long, usually equalling or shorter than calyx in fruit, patent and upturned at apex in fruit. Calyx cylindrical in flower, cylindrical to slightly clavate in fruit, 5-7(-8) mm long. Petal limb white to pink, 1-2(-3) mm, longer than broad, usually emarginate, rarely entire; coronal scales 0.7-1.5 mm, white. Anthers 0.4-1.0 mm, included in corolla tube. Gonophore 0.8-2.2 mm long. Capsule twice to several times as long as the gonophore. Seeds 0.5-0.6 mm wide. Chromosome number: 2n = 24. Distribution: Spread over the Mediterranean area except in the west. A very common plant in Greece, but apparently less common in the rest of its distribution area.
