Notes
| Move to List 4? Location, rarity, and endangerment information needed. Possibly threatened by erosion and recreational activities. Dried material difficult to identify; apparently other taxa are often misidentified as C. lewisii. See Contributions from the U.S. National Herbarium 37(5):275 (1969) for original description. |
