Discussion | Subspecies 5 (5 in the flora). A number of local phases are found in Delphinium parryi. Five of these appear consistently distinct and are recognized here. Other phases may be locally distinct but grade into other nearby phases. Delphinium parryi hybridizes with D. cardinale (D. ×inflexum Davidson). The Kawaiisu used the ground root of Delphinium parryi medicinally as a salve for swollen limbs (D. E. Moerman 1986, no subspecies specified).

Delphinium distichum hybridizes with D. multiplex and D. nuttallianum (D. ×diversicolor Rydberg). The name D. burkei has often been misapplied to D. distichum. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
