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.
