Discussion | Delphinium umbraculorum is most often confused with D. patens subsp. hepaticoideum; refer to discussion of that taxon for distinguishing features. Hybrids occur with D. parryi and D. patens subsp. montanum. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Delphinium andesicola, the westernmost representative of the southern Cordilleran complex, is found in the Chiricahua, Huachuca, Graham, and White mountains. Hybrids with Delphinium scopulorum are known. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
