notes
How rare is this species in CA? Need information on current status, rarity and threats. Not in The Jepson Manual (1993). See Sida 20:121 (2002) for original description and Madrono 51:395 (2004) for information on first report in California. Apparently widespread outside of California where it is known from WA, OR, MT, ID, UT, WY, British Columbia and Alberta. Can be confused with C. douglasii and C. suksdorfii.
