Silene Inflata Smith (S. Cucubalus Wibel.). Bladder Campion. (Plate VIII)

Loosely branched at the base, with ascending or erect stems a foot or more long, of a glaucous green, and usually glabrous. Leaves ovate, oblong, or rarely nearly linear, and usually pointed. Flowers few, white, or pinkish in the mountains, often slightly drooping, in loose terminal panicles. Calyx becoming at length globular, inflated, and much veined. Petals deeply 2-cleft. A variable species, especially in the mountains, where it sometimes assumes a pinkish tinge, as in the plate.

Fields, waste places, and Alpine pastures; very common. April to August.

Distribution

All Europe, Western and Central Asia, Northern Africa, N. America. British.

In Mr. F. N. Williams' European Varieties of Silene inflata1 he describes the var. alpina, Mert. and Koch, and mentions that it was gathered by the present writer on the Col du Galibier in Dau-phiny at 2440 m., "the greatest altitude hitherto recorded for the plant." It was however, recorded at 3000 m. on the Gorner Grat,2 by Heer.

Silene Alpestris Jacq

Root tapering, branched, with woody shoots, tufted. Stems erect or ascending, 6-12 inches high, stiff, glabrous, or with scattered hairs, dichotomously branched above, and viscid at upper part, like the flower-stalks.

Flowers in a terminal, loose few-flowered cyme, white or pinkish. Petals 4-5 toothed. Corona acutely toothed.

Seeds reniform, compressed, surrounded at edge by a radiate, 4-nerved crest of linear scales.

Abundant in the calcareous Alps and lower Alps, 3000-6000 feet, often descending into the valleys with debris. May to August.
