A critical overview of species of the genus Poa (Poaceae) in the flora of Ukraine

Abstract

A brief synopsis of the genus Poa in the flora of Ukraine is presented, which includes 25 species, including those previously not reported in Ukrainian literature (P. egorovae, P. humilis, P. klokovii, P. paczoskii) or reported under other names: P. balfourii (instead of P. janczewskii), P. media and P. laxa (instead of P. ursina). A number of species-rank names are reduced to synonyms: P. biebersteinii, P. erythropoda, P. podolica, P. polonica, P. stepposa, P. fagetorum, P. hypanica, P. sylvicola, P. volhynensis, P. turfosa auct. The species P. egorovae, P. supina remain taxonomically doubtful. The electronic online databases for Ukraine do not recognize Poa klokovii, which, however, merits recognition as a species.
