Discussion

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).

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).
