Discussion

P. A. Munz divided this species into five varieties, based on size of the plants, sepals, and leaflets and whether the leaves are 2-3×-ternately compound. The variation in size of these organs is not discontinuous or even bimodal, however, and I have not seen any material with 3×-ternately compound leaves. For this reason, no varieties are recognized here. The name Aquilegia canadensis var. hybrida Hooker has been misapplied to this species; the type specimen actually belongs to A. brevistyla (B. Boivin 1953).

Aquilegia canadensis has also been reported from New Brunswick, but the specimen has been destroyed and the species has never been recollected in the province.

Native Americans prepare infusions from various parts of plants of Aquilegia canadensis to treat heart trouble, kidney problems, headaches, bladder problems, and fever, and as a wash for poison ivy; pulverized seeds were used as love charms; and a compound was used to detect bewitchment (D. E. Moerman 1986).
