Research was carried out on the total number of bacteria and the number of heterotrophic epiphytic bacteria occurring on the surface of four selected species of freshwater macrophytes predominant in the littoral zone of the southern part of Lake Jeziorak. The highest numbers of bacteria inhabiting the plants being studied were found on the surface of the stems of lesser reedmace, and the lowest numbers on the surface of leaves of floating pond-weed. It was shown that the number of epiphytic bacteria depends on the species of plant, which fragment of it, and the season in which the research is conducted. The results obtained are illustrated with photographs taken under a scanning electron microscope
