The identity of Jacobaea vulgaris Gaertn. subsp. gotlandica (Neum.) B. Nord., hitherto considered an endemic to the Swedish islands Öland and Gotland, was investigated using nrITS and trnTtrnL intergenic spacer sequences and a broad sample of species and accessions particularly of J. vulgaris . We found that J. vulgaris subsp. gotlandica is a distinct evolutionary lineage more widespread in Europe than previously thought and may be a southeastern European steppe floristic element with outliers on the large Baltic islands. Our entirely unexpected findings underline the need of multiple intraspecific sampling in specieslevel phylogenetic studies.
