Discussion

Subspecies purpurascens replaces the Sierran subsp. washingtonianum near Mount Shasta in Siskiyou County, California, and extends west through the Klamath Mountains and north through the Cascade ranges to Mount Hood in Clackamas County, Oregon. In addition to the characters mentioned in the key, subsp. purpurascens is also distinguished from subsp. washingtonianum by more compact bulbs with longer scales.
