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 treleasei is locally abundant but extremely limited by microhabitat within its distributional range.

Hybrids between Delphinium treleasei and D. carolinianum subsp. carolinianum are known.
