Abstract
Correa (family Rutaceae) is a genus endemic to southern Australia, in which chloroplast introgression between species has previously been inferred. The current study aimed to document the extent of incongruence between molecular markers and taxonomy, describe patterns of geographic variation, and infer genetic and biogeographic processes important in the history of the genus. Sampling focused on subg. Correa (nine species) and included 166 samples from 95 localities. Samples were genotyped at the chloroplast loci trnL-trnF and trnK and the nuclear ITS regions, either by direct sequencing or by restriction digests of PCR products. Both chloroplast and ITS datasets resolved subg. Persistens (t..
