Macrophytes diversity and their vegetation is the fundamental key component of any wetland ecosystem. Extensive field survey conducted to document the floristic characteristics of the macrophytes to determine the phytoclimate. Study reveals the enlisting a total of 16 macrophytes belonging to 14 angiosperm families. Analysis of biological spectrum showed the Therophytes (81.25%) were the most dominant life form of the area. So that it directly depicts the therophytic phytoclimate. Total 6 types of leaf size spectra have been found during study. Among these leptophyll(44%) showed the dominance followed by mesophyll (19%) and notophyll (13%). Dominance of therophytes and leptophylls indicate that the vegetation is under biotic pressure due to various anthropogenic activities and the area is subtropical type.
