Abstract
Twenty nine genera of algae belonging to 15 families of the phylum Bacillarophycota were collected during December 2003 and July 2006 from different freshwater habitats in various districts of the Punjab Province of Pakistan. Among them family Pinnularaceae with 19 species was most commonly found (25.33 %), next to it were the families Cymbellaceae (13.33 %), Naviculaceae (13.33 %) and Nitzschaceae (12 %) with 9 or 10 species each. The genera Cymbella with 10 species (13.33 %), Nitzschia with 9 species (12 %), Navicula and Pinnularia with 8 species each (10.66 %) occurred most commonly. About 64 % of diatoms were found as epiphytes
