Notes
| Previously CBR as being a synonym of C. lemmonii; a common taxon. Similar to C. lemmonii; differentiated by floral coloration and in being endemic to volcanic substrates on the flanks of Mt. Lassen versus growing primarily in granitic substrates in the Sierra Nevada. See Leaflets of Western Botany 2:241-245 (1940) for original description, andPhytoneuron 2015-33:1-13 (2015) for taxonomic treatment. |
