The paper presents sinmorphological and sinekological characteristics of floating association Nymphaeetum albo-luteae Nowinski 1928 whose association is developed in pond channels and in the river Stublaja in the Ramsar area Bardaca. Composition and structure of individual associations of this association is very variable. On explored area is present facies with dominant species Nuphar lutea (L.) Sm., while species Nymphaea alba L. enters into floristic composition of only two individual associations on the river Stublaja. Floristic structure of this association made 20 plant species. Individual associations are with closed and typicaly double structure. Characteristic species of association are: Nuphar lutea (L.) Sm. and Nymphaea alba L. Main floristic, physiognomic and cenotic feature of all individual associations gives Nuphar lutea (L.) Sm. which has the highest level of presence and overall coverage value. In the biological spectrum of association cryptophytes are determined, from which aquatic helo- hydrophyte are 80,00% and 20,00% are geophyte. Area spectrum analysis show seven floristic elements, where species with broad outspread dominate (90,00%), while only two species belonging to floristic elements with narrow outspread (Nymphaea alba L. and Trapa natans L.). Community is indicator of stabilization of macrophyte community in succession series and it is considered as a most stabile rooted vegetation, and because of their attractiveness individual associations of this association have significance for the tourist and recreational purposes of the aquatic ecosystems.
