Subspecies 3 (3 in the flora).

Delphinium inopinum is apparently endemic to a white metamorphic rock substrate in the Piute Mountains and southern Sierra Nevada. It is not known to hybridize with any other species, although D. patens subsp. montanum has been collected (when both were flowering) within 1 km of D. inopinum and probably occurs much closer. Delphinium inopinum is often confused with D. parishii subsp. pallidum and superficially resembles some white-flowered individuals of D. hansenii, as well as D. gypsophilum and D. hesperium subsp. pallescens. The massive roots with prominent buds readily distinguish D. inopinum from all of these. In addition, the pubescence found on D. hansenii will separate it from the glabrous D. inopinum. Leaves are rarely seen at anthesis near the base of the stem in D. hesperium subsp. pallescens; they are present in D. inopinum.
