Leaves all basal, the blades orbicular or broadly oval, dull green, thick in texture, somewhat evergreen, blunt or rounded at the apex, 1 to 2 inches long, the margins very obscurely crenulate, petioles about as long or longer than the blades. Flowers pink or purplish pink, one-half to two-thirds of an inch broad; calyx lobes ovate-oblong, one-third as long as the blunt petals; stamens ten, anthers opening by a basal but apparently apical pore as the anther becomes reversed at flowering time, which is true of all species of Pyrola. Fruit capsules about one-fifth of an inch in diameter.

A. Bog Wintergreen - Pyrola uliginosa
In bogs and swamps, Newfoundland to Alaska, south to Vermont, central New York, Michigan. Colorado and California. Considered by some botanists as identical with Pyrola incarnata Fischer, of northern Asia. Flowering in June and July. Rather abundant in open sphagnum bogs of Herkimer, Oneida, Oswego, Madison and Onondaga counties, also in Bergen swamp, Genesee county, and doubtless in other similar bogs throughout western and northern New York.
