Discussion

Of conservation concern.

Aquilegia hinckleyana is endemic to Capote Falls, Presidio County, Texas. The key and description above are based on specimens seen. E. J. Lott (1979) gave the range of sepal width in A. hinckleyana as 9-17 mm, thus overlapping the range in A. chrysantha. She considered sepal shape to be the most reliable key character for distinguishing these species, with sepals less than 2.5 times as long as wide in A. hinckleyana and more than 2.5 times as long as wide in A. chrysantha. Perhaps because of the overlap in characters, she later reduced A. hinckleyana to a variety of A. chrysantha (E. J. Lott 1985). Until her data are published, I prefer to follow the established taxonomy.
