Online published on 25 April, 2016. Abstract A study was designed to assess and understand the floral composition of freshwater lotic diatoms in the tributary of Ganga-Yamuna River System Ken, Paisuni, Tons India. Epilithic samples 33 in numbers were collected between November 2003 and April 2004, by scraping an area of 3x3 cm from cobble surface at the 11 sampling stations Ken, Tons, Paisuni situated between latitude 23°30 ’to 26° N and longitude 78°30 ’to 82°30 ’E. The diatom flora of Vindhya rivers consisted of 293 species and 49 genera. The taxonomic richness in the River Ken, Tons and Paisuni was 205, 202, and 211 respectively. The distribution of diatom in family Thalassiosiraceae, Fragilariaceae, Eunotiaceae & Achnanthaceae were three, twenty eight, six & twenty five respectively. Synedra & Diatoma were species rich genera in family Fragilariaceae however Achnanthes, Planothidium & Cocconeis in family Achnantheaceae.
