Abstract:

Forty-two species of the genus Spirogyra Link (Chlorophyta) were collected from various freshwater habitats in Gujranwala, Jhang, Kasur, Lahore, Sheikhupura and Sialkot and Attock Districts of the Punjab Province and Swat of N. W. F. Province as well as Chenari and Neelum Valley of Azad Kashmir during January 2004 and April 2005. They were taxonomically investigated and have been described for the first time from their area of collection. Out of these, 22 species are being reported for the first time from any area of Pakistan. They thrived luxuriantly during winter and spring seasons, started diminishing in summer and disappeared to a great extent in autumn.
