Impact of glacial history on the phylogeography of silicate-dwelling plants of the European Alps has been particularly well studied, whereas virtually no data are available for species growing on different bedrock types, as for Hornungia alpina. Bayesian clustering of AFLP data only partly support the distinction of three subspecies as morphologically defined. Whereas the phylogeographical N-group corresponds to subsp. alpina, the congruence of the SW-group and SE-group with subsp. brevicaulis, and subsp. austroalpina, respectively, is limited. High levels of rarity and genetic diversity in the N-group suggest Pleistocene survival along the outer margin of the Alpine arc. For subsp. brevicaulis we suggest a single origin from a refugium in the Southwestern Alps, whereas subsp. austroalpina might have originated twice in the Southern and Southeastern Alps. Different levels of genetic diversity and partitioning of genetic variation indicate a divergence in breeding system, which is corroborated by pollinator exclusion experiments revealing self-incompatibility in the N-group and autonomous selfing in the SE-group.
