Discussion | Subspecies 3 (3 in the flora). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Subspecies 2 (2 in the flora). Delphinium bicolor is closely related to D. glareosum; it differs in its wider-lobed cauline leaves, shallower petal clefts, and narrower fruits. The Gosiute consider this plant to be poisonous (D. E. Moerman 1986, subspecies not specified). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
