Despite their relatively limited extension, the Baetic Mountains contain almost 50% of the total endemic <em>Erysimum</em> species in the Iberian Peninsula. The broadly distributed <em>Erysimum</em> genus has diversified profusely in the Mediterranean region, with more than a hundred species described in the area, out of a total of c. 200 species included in the genus. We used two plastid DNA regions (<em>ndhF</em> and <em>trnT-L</em>) and one nuclear DNA region (ITS1-5.8S rDNA-ITS2), with 3,556 bp total length, to carry out phylogenetic analysis by Bayesian inference, maximum likelihood and maximum parsimony, in order to explore the evolutionary relationships between the <em>Erysimum</em> species inhabiting these ranges. Analyses of concatenated sequences from the two genomes identified two main clades with no overlap in species composition so that samples from the same species fell within the same major clade. The phylogenetic relationships depicted by those two clades do not give support to the <em>E. nevadense</em> group, previously proposed on taxonomic grounds. In addition, our results indicated recurrent changes in flower colour in the Baetic <em>Erysimum</em> species although, alternatively, reticulate evolution, which is suggested by incongruent position of taxa in the different trees, may have also affected this trait.
