Aquilegia formosa var. truncata replaces A . formosa var. formosa from the Sierra Nevada westward. The two varieties intergrade where they come together.

The common form of Aquilegia formosa var. truncata is 50-100 cm, with well-developed stem leaves. Montane forms with short stems and very small stem leaves are often separated as A . formosa var. pauciflora . Similar dwarf montane races with the floral characters of A . formosa var. formosa occur in the Pacific Northwest; these have never been separated taxonomically.
