Discussion

Aquilegia flavescens sometimes forms hybrid swarms with A. formosa var. formosa, which grows at lower elevations through much of its range. Intermediate specimens having pinkish red flowers and petal blades 5-6 mm are occasionally found where these species grow together. The name A. flavescens var. miniana has sometimes been mistakenly applied to these intermediates, but the type of var. miniana is a typical, pink-sepaled plant of A. flavescens.
