A cryptic taxon rather than a hybrid species of Tragopogon (Asteraceae) from the Czech Republic

Popis výsledku v původním jazyce

Tragopogon xmirabilis Rouy is described as a diploid hybrid between T. porrifolius and T. pratensis. A population of T. xmirabilis from Central Bohemia, Czech Republic, was recently investigated and, unlike previous reports of T. xmirabilis, was found tobe highly fertile. This fertile diploid hybrid population was considered to represent an alternative evolutionary pathway to polyploidy in Tragopogon. To determine the parentage of the plants from Bohemia, we investigated 12 samples of T. xmirabilis with ITS, ETS, LFY and plastid (rpL16 gene, intron 1, tRNA-Leu (trnL) gene, intron, trnL-trnF intergenic spacer, psbA-trnH intergenic spacer, and trnG-trnT intergenic spacer) sequence data. None of the Bohemian plants have sequences that are consistent witha hybrid origin between T. porrifolius (incl. T. australis) and T. pratensis. Our data suggest that this fertile population of "T. xmirabilis" may represent an unrecognised diploid species from the Angustissimi clade sensu Mavrodiev et a
