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
Htdrodictyon 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. Of the three species, H.
patenaeforme is reported from Chetawala Ghat, Ganga Khadar, Hastinapur is the first report
and new addition to the Hydrodiction flora of India.
