Discussion | Of conservation concern. The range of morphologic features of Delphinium nuttallii subsp. ochroleucum (D. leucophaeum) is almost completely encompassed within that of D. nuttallii subsp. nuttallii. Sepal color is the only feature consistently separating the two subspecies. Were it not for the fact that any given population typically has plants of only one flower color, a rank of forma would be more appropriate.

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.) |
