Discussion

This subspecies occurs in two chromosomal races: tetraploids (2n = 32), distributed from the Cascade Mountains of Oregon southward throughout the Coast Ranges to central California, and diploids (n = 16), distributed from Vancouver Island and British Columbia southward through the Cascades and Coast Ranges, and along the western slopes of the Sierra Nevada to Monterey and Tulare counties, California. The flowers of both races vary appreciably in color, shape, and size.
