Riparian floristic elements in the lower stretch of River Chaliyar flowing through Kozhikode District, Kerala, India was analyzed and documented taxonomically. There are about 171 species belonging to 45 families and 134 genera were documented. In dicotyledons Asteraceae is the dominanat family with 17 species belongs to 15 genera followed by Fabaceae with 14 species belongs to 10 genera and Euphorbiaceae with 12 species belongs to 10 genera. Similarly, in monocotyledons, Poaceae is the dominant family with 20 species belongs to 12 genera. The life form analysis of the documented Riparian plants reveals that, herbs are dominant (99 in nos.), followed by shrubs (30 in nos.), trees (22 in nos.) and climbers (20 in nos.). The present study also highlighted the threatening factors that affect the distribution of plant species in the riparian regions. Many exotic plants are luxuriantly growing in the riparian regions which are also documented, there are about 51 species belongs to 43 genera and 22 families are exotic plants in the study area.
