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 robustum is the representative of the southern Cordilleran complex from the Jemez, San Antonio, San Juan, San Pedro, and Sangre de Cristo mountains. Hybrids are known with D. sapellonis. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
