Stems: erect. Leaves: oblong-cordate, irregularly crenate-toothed. Flowers: sepals petaloid, lanceolate, acute.
This plant is found chiefly in moist localities, and often grows abundantly in the wet alpine meadows at high elevations, where its white flowers, whose petaloid sepals are deeply tinged with purple-blue on the outside, are extremely beautiful set among their rich large-leaved foliage. The stems bear one or two flowers, the lower of which is subtended by a noticeable leaf-like bract.
