The Meerut region of India is well-known for its rich bio-diversity of flora and fauna
including green algae. Since there are no previous records on the diversity of green alga
Hydrodictyon from Meerut and Hastinapur, this study serves as the first documentation from
the region. From the present communication we are reporting three species of Hydrodictyon,
including H. reticulatum, H. indicum and H. patenaeforme from two natural fresh water
biotopes of Meerut region of India, including the Chetawala Ghat, Ganga Khadar, Hastinapur
and Cantonment area near the Kendriya Vidyalaya Sikh Lines, Meerut, Uttar Pradesh, India.
Of the three species, H. patenaeforme ireported from Chetawala Ghat, Ganga Khadar,
Hastinapur, Meerut (U.P.) is the first report and new addition to the algal flora of
India.
