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. 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.) |
