Occurrence in Inner Mongolia, N China, is probable but material has not been seen. A very
variable subspecies; many aberrant populations are found in the S part of the North
American range. Intermediates between the type subspecies and subsp. fastigiata have been
reported from Alaska, British Columbia, Wyoming, California, Utah and Colorado.
