On the origin of orphan hybrids between Aquilegia formosa and Aquilegia flavescens.

ABSTRACT: We report the investigation of an Aquilegia flavescens × A. formosa population in British Columbia that is disjunct from its parents-the latter species is present locally but ecologically separated, while the former is entirely absent. To confirm hybridity, we used multivariate analysis of floral characters of field-sampled populations to ordinate phenotypes of putative hybrids in relation to those of the parental species. Microsatellite genotypes at 11 loci from 72 parental-type and putative hybrid individuals were analysed to assess evidence for admixture. Maternally inherited plastid sequences were analysed to infer the direction of hybridization and test hypotheses on the origin of the orphan hybrid population. Plants from the orphan hybrid population are on average inter
