摘要

The present work included study of epiphytic algae on two species of aquatic plants (Potomogeton crispusand Eusine indica ) of Al – Abasia / Euphrates river in the middle region of Iraq from March 2012 to February2013.The investigation region encompassed four sites along 28 Km of the river course the study was recorded 152species of epiphytic algae on both host plants species and comprised of Bacillariophyta (70%) , Chlorophyta (22%)and Cyanophyta (8%) ,Total number of epiphytic algae was ranged between 117.03 x103was individual /g as lowvalue on shoot of E. indica and 12801.12 x103individuals /gm as high value on leaves of P.crispus .Some species were recorded as dominance during most of the study period on both host plant species , suchas Osillatoria sp . ; Scendesmus sp. ; Cyclotella comta ; Nitzshia sp . ; Melosera italic and Navicula easpidata. Theresults showed high species richness and low diversity of epiphytic algae according to Shannon index in all studysites.
