Discussion | Delphinium nudicaule hybridizes with most other taxa of Delphinium that it encounters. Apparent hybrids involving D. nudicaule, and seen by the author (either afield or as specimens), include D. andersonii, D. antoninum, D. decorum, D. luteum, D. nuttallianum, D. patens, and D. trolliifolium. In addition, garden-grown plants have been hybridized with D. cardinale, D. elatum, D. menziesii, D. parishii, D. penardii, D. tatsienense Franchet, D. triste Fischer ex de Candolle, and D. uliginosum; D. nudicaule does not naturally occur with these species. Delphinium nudicaule is one of the earliest larkspurs to flower in any given locality. Douglas's type collection of D. nudicaule represents plants (synonyms D. sarcophyllum Hooker & Arnott and D. peltatum Hooker, an invalid name) grown under very moist conditions, probably quite near the ocean. The type specimen of D. armeniacum A. Heller represents plants grown under unusually dry conditions. The Mendocino Indians consider Delphinium nudicaule a narcotic (D. E. Moerman 1986).

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).
