One hundred and sixty three species were recorded. These species belong to 8 species (4.9%) of Ferns, 95 species (58.3%) of Eudicots, 2 species (1.2%) of Magnoliids and 58 species (35.6%) of Monocots. They are composed of 55 species of aquatic plants and 108 species of terrestrial plants. The aquatic plants could be divided into 38 species of annual plants and 17 species of perennial plants. The terrestrial plants could be divided into 25 species of annual plants and 83 species of terrestrial plants.
