Aconitum delphiniifolium is variable and was divided into three intergrading subspecies by E. Hultén (1941-1950, vol. 4) on basis of plant size, flower size, number of flowers, petal morphology, and narrow versus somewhat broader leaf lobing. Because of the "paucity of definitive criteria," J. A. Calder and R. L. Taylor (1968, vol.1) and S. L. Welsh (1974) chose not to recognize infraspecific taxa within A. delphiniifolium. Similarly, we have deferred formal recognition of infraspecific taxa within this species pending population studies. The most distinctive group within A. delphiniifolium has one to several large flowers with shallow nectaries borne on diminutive plants. These are sometimes distinguished as subsp. paradoxum, and they exhibit a different pattern of variation from that found in A. columbianum, in which large flower size is associated almost invariably with large, robust plants and deep nectaries.
More typical forms of Aconitum delphiniifolium are similar to A. columbianum except that leaves tend to be more deeply divided and the hood tends to be lower, i.e., more crescent-shaped and less conic. Some plants and populations of A. columbianum also have leaves divided almost to the base and low hoods. Intergradation between the two species should be investigated more fully.
The Salishan used Aconitum delphiniifolium for unspecified medicinal purposes (D. E. Moerman 1986).
