Hieracium tomosense Simk., a mountain forest species known to date only from the Piatra Mare Mts in the Southern Carpathians, Romania, has been found in other parts of the Southern and Eastern Carpathians. This hybridogenous species of the morphological formula H. transylvanicum > H. murorum was incorrectly included by Zahn and Nyárády into H. transylvanicum Heuff. as a variety, thus sending H. tomosense into oblivion. A distribution map of H. tomosense is presented and its relation to H. praecurrens is discussed. The name H. tomosense is lectotypified by a specimen stored at the Hungarian Natural History Museum in Budapest (BP).
