Aquilegia chrysantha A. Gray var. rydbergii Munz

Synonym: Aquilegia chrysantha A. Gray var. chrysantha

Family: Ranunculaceae

Description: Colorado populations of A. chrysantha supposedly have spurs only 35-40 mm long, which was the justification for the varietal status.

Specimens Seen or Cited: There are no collections of var. rydbergii at UNM, NMSU, UTEP, NAU, ASU, BYU, San Juan College, and NNHP. The herbarium in Boulder, Colorado, has 7 collections, all from El Paso Co, CO, where it appears to be the common variety.

Discussion: Alan T. Whittemore, who did the treatment of Aquilegia for the Flora of North America believes that material called A. chrysantha var. rydbergii seen from Colorado falls within the normal range of variation for the species and should be treated as a synonym of the common A. chrysantha.
