Variety sandbergii is restricted to a series of scattered populations in the foothills and low mountains of the north Cascade Ranges of north-central Oregon (Hood River and Wasco counties) and central Washington (Chelan, Kittitas, Okanogan, and Yakima counties). It appears to be most closely related to the more southern, matted var. modocense.
