In this study, epipelic algae and epiphytic algae which grow on the surface of submerged macrophyte Phragmites australis at Al-Sadir River in Al-Najaf province (Iraq) were investigated. The samples were collected monthly from three sites in this river for six months from January to June 2015. Many physicochemical variables were measured include water temperature, electrical conductivity, salinity, turbidity, pH, dissolved oxygen, Total Alkalinity, Total Hardness, calcium ion, magnesium ion, nitrite, nitrate, and Phosphates. The results showed that the number of epipelic algae was 100 species, while the number of epiphytic algae was 143 species. Diatoms were predominant over other algae species during the study period. Some benthic algal genera existed in most of the study months, including Navicula, Nitzschia, and Cymbella. The number of species common between the two algal groups (epipelic and epiphytic) was 62 species. The highest number of epipelic algae reached 9.09 cell×104/cm² and the lowest number was 0.18 cell×104/cm², while the highest number of epiphytic algae was 54.36 cell × 104/g and the lowest number was 2.04 cell×104/ g.
