Abstract
Two apomictic, polyploid (x=9) species in Hieracium sect. Alpina are described from the Western Bieszczady Mountains, Eastern Carpathians, Poland, and illustrated with photos of the holotypes. These are H. jasiewiczii (4x) which combines the morphological features of H. alpinum and H. bifidum, and H. wojcickii (4x) of presumably hybrid origin between H. alpinum and H. pseudobifidum. Both new species are probably relicts originated from diploid, sexual H. alpinum with a wider primary range covering also the Western Bieszczady Mountains, which presently occurs only in the Romanian and Ukrainian Carpathians.
