Abstract

---

Ten species of Zygnema C. A. Agardh (Zygnemophyceae, Chlorophyta) were collected during December 2003-December 2004 from different freshwater habitats of Gujranwala, Kasur, Lahore, Sheikhupura, Sialkot and Pasrur districts of the Punjab, Attock and Swat in N.W. F. P. of Pakistan and Neelum Valley of Azad Kashmir. They were taxonomically determined and have been described for the first time from these areas. Their reproduction was observed to occur mostly in winter and spring. They were usually found abundant in permanent water habitats.
