Scorzoneroides montana (LAM.) HOLUB s. 1. (Asteraceae -Cichorieae) and its Relatives

The splitting of the genus Leontodon into two distinct genera - Leontodon s. str. and Scorzoneroides - based on molecular and morphological characters is more and more accepted. In the European mountain ranges six population groups of Scorzoneroides montana agg. are occurring. These groups inhabit areas geographically more or less disjunctive from each other. A new taxonomic system for these groups is proposed. Based on morphological characters and distribution areas three species are accepted: S. montana (L.) HOLUB s.l., S. montaniformis (WIDDER) GUTERMANN, and S. pseudotaraxaci (SCHUR) HOLUB. S. montana is divided into four subspecies: S. m. subsp. montana, S. m. subsp. melanotricha (VIERH.) GUTERMANN, S. m. subsp. breviscapa (DC.) GREUTER, and S. m. subsp. illyrica (K. MALY) ZIDORN, comb. nova.
