Variety albida is found in the Cascade Range of southern British Columbia southward to the Wenatchee Mountains of Washington. In central British Columbia, the point of transition into var. parviflora still needs definition. Variety albida is characterized by whitish to cream bracts, although some plants in Okanogan County, Washington, have pink or purple bracts in mixed populations with white-bracted plants.
"arising" is not a number.
