Colorado populations supposedly having spurs only 35-40 mm have been called Aquilegia chrysantha var. 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).
