One hundred ninty-five species of planktonic, edaphic, epipsammic, epiphytic, epioikotic and epilithic blue-green algae belonging to 2 classes, 4 orders, 9 families and 50 genera have been collected from various freshwater habitats in the districts of Attock, Gujranwala, Jauharabad, Jhang, Kasur, Lahore, Pasrur, Sargodha, Sheikhupura and Sialkot in the province of the Punjab, as well as from N.W.F.P., Pakistan and Azad Kashmir during March 1996 and August 2000. Among them 16 genera and 73 species are recorded for the first time from Pakistan. Members of the class Nostocophyceae with 144 species were found to be more prevalent than those of the class with 51 species. Oscillatoria with 34 species was the most commonly occurring genus. Greatest species diversity was exhibited by the collections made in Lahore and neighbouring areas. Heterotrichous species were only scarcely observed. Their growth was most abundant in the aquatic environment especially in planktonic state than in the terrestrial environment in benthic condition.
