This paper presents results of a detailed investigation into the qualitative composition of the desmid flora of the Danube performed from April of 2002 to May of 2003. A total of 70 desmid taxa belonging to four genera were recorded. Forty-seven taxa are new to the Vojvodina stretch of the Danube, while Cosmarium kjellmanii, Staurastrum bloklandiae, and S. smithii are taxa new to the algal flora of Serbia. Qualitative dominance of desmid taxa typical of alkaline and eutrophic ecosystems was observed. The qualitative composition of planktonic taxa, their quantitative composition, and regular seasonal dynamics of the desmid community were analyzed in the relation to physico-chemical characteristics of the water. Water quality was analyzed on the basis of desmids, which are bioindicators. The partly unexpected presence of certain desmid taxa, i.e., several typical acidophilous species, alpine forms, and/or taxa characteristic of oligotrophic water was recorded
