A new hybrid combination Pilosella onegensis Norrl. × P. praealta (Vill. ex Gochn.) F. Schultz & Sch. Bip. is recognised on the basis of its intermediate morphological characters, and described under a new binomial name, P. × tambovica Sennikov. All old records of P. caespitosa (Dumort.) P.D. Sell & C. West and many such of “Hieracium nestleri Vill.” from the Tambov Region of European Russia are found referable to P. onegensis.
