Discussion
Variety oreopola is restricted to the Cascade Range from central Oregon, near the Three Sisters peaks, to just north of Mt. Rainier, in Washington. It is replaced to the north in the Wenatchee Mountains and the North Cascade Range by var. albida. Variety oreopola usually has pink to purple inflorescences, with occasional variants of pinkish red, pinkish orange, or white. Its colorful displays are a conspicuous element of the subalpine meadows and slopes of this region. Reports of var. oreopola in the Cascade Mountains of southern British Columbia seem plausible but have yet to be fully verified.
