Discussion | Delphinium barbeyi hybridizes extensively with D. glaucum in western Colorado and eastern Utah, where plants appearing to be hybrid [D. ×occidentale (S. Watson) S. Watson] are often far more common than plants of either putative parent. Several other names have been used for these plants, including D. elatum var. occidentale S. Watson, D. abietorum Tidestrom, and D. scopulorum subsp. occidentale (S. Watson) Abrams. Delphinium barbeyi is also known to hybridize with D. ramosum and D. sapellonis.

Of conservation concern. In addition to the Alabama sites, Delphinium alabamicum is known from one population in Georgia; it might have been transplanted there. Delphinium alabamicum has not been seen in central Alabama since 1950; populations there might have been extirpated. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
