Columbines: a geographically widespread species flock.

Proceedings of the National Academy of Sciences of the United States of America - 24 May 1994

Hodges S A, Arnold M L

Abstract excerpt

Species in the columbine genus, Aquilegia, are known for their broad variation in ecology and floral morphology. Aquilegia is also known for the large degree of intercompatibility among its species, which has led to the suggestion that the genus has arisen recently. However, intercompatibility does not always imply recent divergence and the widespread distribution pattern of the genus has suggested an older age....
