abstract = {Allopolyploidy is recognized as an important mode of plant speciation. The allopolyploid origin of a taxon is often inferred from morphological intermediacy or a mixture of morphological characters from the putative parental taxa, especially if accompanied by geographical intermediacy of the polyploid. Here we show that in the case of Androsace cantabrica (Primulaceae) a narrow endemic from the central Cordillera Cant?brica (Spain) both lines of evidence are misleading. Instead of being an allopolyploid derivative of A. halleri s. l. (western Cordillera Cant?brica, eastern Pyrenees, Massif Central, Vosges) and A. laggeri (central Pyrenees), A. cantabrica is most likely an autopolyploid closely related to A. adfinis s. l., endemic to the south-western European Alps. This counterintuitive biogeographic connection not only adds to the group of species showing a CantabrianAlpine disjunction, but together with the unexpected link between A. chaixii, also from the south-western Alps, and A. halleri s. l. in form of the northern Spanish local endemic A. rioxana underlines the important role of large-scale range shifts in shaping the current distribution of European mountain taxa.}
