Ph.D.Thesis: Result on Floral diversity of aquatic angiosperm plants: Ecofloristic survey of aquatic and marshy land angiosperms of Paschim Medinipur district, West Bengal, India. 6. Results 6.1. Floral diversity of aquatic angiosperm plants 6.1.1. General enumeration of aquatic and marshy land angiosperms: After a long survey during the 2008-2016 total of 160 angiosperm plant species recorded from the different aquatic zone of this district. Among these 92 plant species are monocot and 68 plant species are dicot. These 92 monocot plant species belong to 54 genera under the 15 families. Dicot 68 plant species are belonging to 39 genera under the 28 families.
