Premise of the Study The origin of allopolyploids is believed to shape their evolutionary potential, ecology and geographical ranges. Morphologically distinct apomictic types sharing the same parental species belong to the most challenging groups of polyploids. We evaluated the origins and variation of two triploid taxa (Hieracium pallidiflorum, H. picroides) presumably derived from the same diploid parental pair (H. intybaceum, H. prenanthoides). Methods We used a suite of approaches ranging from morphological, phylogenetic (three unlinked...
