Discussion

Colorado populations supposedly having spurs only 35-40 mm have been called Aquilegia chrysantha </i>var.<i> rydbergii. Material seen from this area falls within the normal range of variation of the species. Populations intermediate between A. chrysantha and A. coerulea var. pinetorum occur in northern Arizona (M. Butterwick et al. 1991).
