Abstract

Interspecific plant hybridization is a common and evolutionarily important phenomenon. Here, the results of a study of hybridization in the Florida Keys between two species of sea oxeye daisy, Borrichia frutescens and B. arborescens, are reported. Nuclear and chloroplast genetic loci, log-likelihood assignment tests, and maximum likelihood estimates of genealogical class frequencies were used to identify hybrid and parent genotypes, to investigate the utility of leaf and flower morphology for hybrid identification, and to study symmetry and degree of introgression between the species. Genetic analyses confirmed the identity of the hybrid and parent plants that were used for the morphological..
