In the present study, in order to investigate the flora of Zayandeh-Rood River, a list of aquatic macrophytes (submerged and emergent) and coastal plants along with geographical distribution (chorotype) and their life forms were compiled. A total of 92 species and 79 genera belonging to 36 families were identified. Poaceae (15 genera and 16 species), Amaranthaceae (8 genera and 10 species), Asteraceae (7 genera and 7 species), Brassicaceae (5 genera and 5 species), Fabaceae (4 genera and 4 species), and Potamogetonaceae (3 genera and 6 species) were the most important plant families. The highest number of identified species had the life forms of hemicryptophytes and throphytes (31.52%), helophytes and hydrophytes (13.04%), geophytes and phanerophytes (4.35), and chamaephytes (2.18%), respectively. Investigating the geographical distribution showed that the largest portion of the geographical distribution of plants in the region belonged to plural elements (25%), cosmopolitan elements (14.13%), Irano–Turanian elements (13.04%), and Irano-Turan-Euro-Sieberian elements (7.61%). The study indicated the diversity of aquatic and coastal vegetation of Zayandeh-Rood River that should be considered for conservation.  https://tbj.ui.ac.ir/article_25192_596e09fe74d9d5b0b6871ab89c172afb.pdf
