Rank Reasons
California endemic known from 19 extant and four historic occurrences from San Bernardino and Riverside Counties. Occurrences are in the San Jacinto Mountains, where they may be somewhat buffered from the numerous threats in southern California. Threats listed include foot traffic and trampling. Since this plant may have horticultural value, collecting may also be a factor. For sites on private lands, development is a threat.
