We used sequences of nrDNA ITS and chloroplast gene matK to evaluate the monophyly of Empetrum and Corema and to examine phylogenetic relationships of the Empetraceae. Sequences of these two DNA markers were obtained for 11 plant samples, representing species of Empetrum from both the Southern and Northern Hemispheres, species and subspecies of Corema, and the monotypic Ceratiola. Sequences of four species of Rhododendron were used for rooting purposes. Our results show that species of Empetrum form a clade sister to the clade containing both Corema and Ceratiola. These two clades are strongly supported in both the matK and ITS trees, suggesting that Ceratiola is more closely related to Corema than to Empetrum, and is not of a hybrid origin between the ancestors of the latter two genera. In the matK tree, Corema conradii is more closely related to Ceratiola than to Corema album and C. album subsp. azoricum, whereas in the ITS tree, Ceratiola is allied with Corema album and C. album subsp. azoricum. This suggests that C. conradii might be a hybrid between ancestral populations of Ceratiola and C. album. The monophyly of Empetrum rejects the hypothesis of its independent origin in the two Hemispheres. Our trees also suggest the fact that the modern amphitropical distribution of Empetrum is the result of long distance dispersal, not of the vicarious events.
