Senecio tauricus (Asteraceae) was described as an endemic species restricted to the mountain plateaus (yailas) of the Crimean Peninsula, growing only in meadow-steppe plant communities. The species status for this taxon was accepted in all relevant floras, identification manuals, and checklists; it is also listed in the current edition of the Red Data Book of Ukraine (2009) and some other lists of protected plant species. Following the results of recent molecular phylogenetic studies that justified the segregation of several genera housing taxa earlier placed in Senecio sensu lato, the new nomenclatural combination Jacobaea taurica is proposed. Basic information on morphology, ecology and distribution of J. taurica and related taxa is also briefly discussed and summarized.

Keywords: Senecio, Jacobaea, Asteraceae, nomenclature, taxonomy, Crimea, endemic species
