Description	Phylogenetic relationships for Hieracium subgen. Pilosella were inferred from chloroplast (trnT–trnL, matK) and nuclear (ITS) sequence data. Chloroplast markers revealed the existence of two divergent haplotype groups within the subgenus that did not correspond to presumed relationships. Chloroplast haplotypes of Hispidella and Andryala nested within these two groups. ITS data were in accord with morphology and reflected the true phylogeny. They revealed a sister relationship between Pilosella and Hispidella and a joint clade of Hieracium and Chionoracium while Andryala represented a third lineage. Detailed analysisof trnT–trnL character state evolution along the ITS tree suggested two intergeneric hybridization events between ancestral lineages that resulted in cytoplasmic transfer. These chloroplast capture events, the first of which involved a now extinct haplotype, are the most likely explanation for the incongruencies between plastid and nuclear DNA markers.
