Notes

Rediscovered at Point Arena in 2011 by R. Korhummel. Many historical occurrences may be extirpated; need field surveys. Possibly threatened by non-native plants and shoreline retreat. Known to occur on Gnaphalium, Silene, and Lupinus spp. in MEN Co.; and on Polycarpon tetraphyllum and Calystegia purpurata ssp. saxicola with Sanicula arctopoides nearby in SON Co. Similar to C. pacifica var. pacifica and C. salina. See C. salina var. papillata in The Jepson Manual (1993). Treated as extirpated in TJM 2. See Bulletin of the Torrey Botanical Club 69(7):541-543 (1942) for original description and Systematic Botany 34(4):787-795 (2009) for taxonomic treatment.
