A New Polyploid Species of the Genus Tragopogon (Asteraceae, Cichorieae) from Russia

ABSTRACT Tragopogon soltisiorum Mavrodiev (Asteraceae, Cichorieae, Scorzonerinae) is described as a new species. The new species is a tetraploid (2n = 24), ruderal plant with long flowering and fruiting times and differs from the vast majority of Tragopogon L. species in its ability to reproduce vegetatively from adventitious shoots. The new species is known only from southern Russia and is found in two varieties—a typical variety and a new variety latifolius Mavrodiev.
