Discussion | Of conservation concern. Delphinium purpusii is not likely to be confused with any other Delphinium in North America. Hybrids with Delphinium hansenii subsp. kernense are known to occur. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Of conservation concern. Delphinium antoninum hybridizes with D. decorum subsp. tracyi and with D. nudicaule. Most often confused with D. decorum subsp. tracyi, it is separable on the basis of its longer root, usually reflexed sepals, and typically colorfast flowers. It also may be confused with D. andersonii; see discussion under that species. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
