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).

Of conservation concern.

Delphinium hutchinsoniae is known from only a few populations near Monterey and south to the Big Sur region. Hybrids have been produced between D. hutchinsoniae and D. cardinale grown in a common garden. Hybrids also occur with D. parryi subsp. maritimum.

Delphinium hutchinsoniae is similar, and probably closely related, to D. variegatum. The two may be distinguished by the decurved spur of D. hutchinsoniae; the spur of D. variegatum is normally straight (or decurved nearer apex). Delphinium hutchinsoniae lacks marginal hairs on lower petals; such hairs are present in D. variegatum. The two species are also geographically separated.
