Discussion

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.
