Notes: The treatment here follows H&C, which is not consistent with the FNA3 treament of D. nuttallii ssp. ochroleucum:
"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."
