Notes
| Discovered in CA by D. York in 2011; known in CA only from the Marble Mtns. Possibly threatened by global climate shifts and stochastic events. If taxonomically recognized, some North American populations would be attributed to C. hepburnii. Not in TJM 2. See Novitiarum Florae Suecicae Mantissa 2:55 (1839) for original description, and Madroño 59(4):231 (2012) for information on discovery in CA. |
