Notes

Known from fewer than 10 occurrences, though only observed at two locations in recent years; fewer than 100 plants are estimated to remain as of 1993. Specimens from outside SDG Co. and BA are probably misidentified or planted. Threatened by urbanization. See Bulletin of the Southern California Academy of Sciences 16:50 (1917) for original description, and Systematic Botany 16(1):3-20 (1991) for taxonomic treatment.
