Discussion

Species ca. 70 (21 in the flora).

Species of Aquilegia are polymorphic and difficult to define adequately. Some of the variability is because of introgressive hybridization. Even distantly related species of columbine are often freely interfertile, and many cases of natural hybridization and introgression are known from North America. Only the most important are mentioned below. In arid areas Aquilegia species tend to form small populations often completely isolated from one another. This leads to local fixation of genes and therefore increased variability in species such as A. micrantha and A. desertorum. In addition, populations with spurless petals are occasionally found in many species.
