    This variety is comprised of two clusters of occurrences straddling a small area of the California-Nevada border near Lake Tahoe. Less than 20 total occurrences are estimated, with a total population of approximately 17,000 plants. Nevada occurrences face the relatively significant threat of ski resort development, while California occurrences appear to be less threatened.
