Leaves linear to narrowly oblanceolate, greater than 3 mm wide, pale to dark green, serrations absent or towards apex only, lamina continuous over midrib and leaves not bifurrowed; flowers pink to deep magenta – 2

2. Leaves 4–15 cm long, pale to mid-green, widely spreading to suberect; scape fine (< 2 mm wide), glabrous or glabrescent below lowest flowers; flowers 10–30; in water-retentive, peaty soils of montane to subalpine areas at high altitudes – S. montanum

Leaves 20–40 cm long, dark green, spreading to erect; scape robust (>2 mm wide), glandular–pubescent beyond lowest flower; flowers 30–120; widespread from coast to alps – S. armeria
