abstract = {A molecular phylogenetic study of the Macaronesian genus Bystropogon (Lamiaceae) is presented. We performed a cladistic analysis of nucleotide sequences of the Internal Transcribed Spacers of the nuclear ribosomal DNA and of the trnL gene and trnL-trnF intergenic spacer of the chloroplast DNA. Non-functional ITS copies were found in B. canariensis var. smithianus from the islands of La Palma and La Gomera. Bystropogon odoratissimus is the only species endemic to the Canary Islands that occurs in the three paleoislands of Tenerife. This species is not part of a stem-based group of Bystropogon and we suggest that it has a recent origin. This phylogenetic pattern is followed by the majority of species endemic to the paleoislands of Tenerife. The two taxonomic sections currently recognized in Bystropogon form two distinct monophyletic groups in our molecular phylogeny. Taxa belonging to the section Bystropogon clade show interisland colonization limited to the Canary Island archipelago with ecological shifts among three ecological zones. Taxa from the section Canariense clade show interisland colonization both within the Canary Islands and between the Canary Islands and Madeira. Speciation events within this clade are limited to the laurel forest ecological zone. The genus has followed a colonization route from the Canaries towards Madeira, this route has also been followed by at least five other plant genera with species endemic to Macaronesia. Major incongruences were found between the current infra-sectional classification and the molecular phylogeny because the varieties of B. origanifolius and B. canariensis do not form two monophyletic groups}
