Polypogon viridis (Poaceae): nova vrsta trave u flori Bosne i Hercegovine

Water Bent Polypogon viridis (Gouan) Breistr. is native to damp places in southern Europe, the Mediterranean, South-West and Central Asia and North-East Africa and was introduced into North and South America and Australia. It has been recorded for the first time in Bosnia and Herzegovina in northeastern Bosnia at the beginning of the summer in 2017, in the vicinity of the village Bakovići near Banovići. The paper presents a short morphological description and photographs of the new species for Bosnia and Herzegovina, as well as the known distribution of the species. A determination key is given for Polypogon taxa registered in Bosnia and Herzegovina and neighbouring countries.Polypogon viridis (Gouan) Breistr. je autohtona vrsta vlažnih staništa južne Europe, Sredozemlja, sjeverozapadne i središnje Azije kao i sjeveroistočne Afrike, dok je unešena u Sjevernu i Južnu Ameriku te Australiju. Početkom ljeta 2017. godine je po prvi put zabilježena u Bosni i Hercegovini, kod Bakovića u blizini Banovića. U radu se donosi kratak opis morfoloških karakteristika vrste, karta poznate rasprostranjenosti te ključ za određivanje vrsta roda Polypogon zabilježenih u Bosni i Hercegovini i susjednim zemljama
