Fig. 3200

Pyrola uliginosa Torr. Fl. N. Y. 1: 453. pl. 60. 1843.

Pyrola rotundifolia var. uliginosa A. Gray, Man. Ed. 2, 259. 1856.

Scape 6'-15' high, 7-15-flowered. Leaf-blades broadly oval, or orbicular, dull, rather thick, obscurely crenulate, obtuse at both ends, sometimes truncate at the base, equalling or shorter than their petioles; bracts shorter than or equalling the pedicels; flowers purple, 5"-8" broad; calyx-lobes ovate-oblong or ovate-lanceolate, acute or obtuse, one-fourth to one-third the length of the obtuse petals; stamens and style declined-ascending; anther-sacs beaked; style slightly exserted; capsule about 2\" in diameter.

In swamps and bogs, Newfoundland to Alaska, Vermont, central New York, Michigan, in the Rocky Mountains to Colorado, and to California. Similar to the Asiatic P. incarnata Fisch., and perhaps not specifically distinct from it. June-July.
