Life form and leaf size spectra of 15 ecologically different plant communities were studied by Raunkiaerian and quantitative ecological method. These communities were grouped in to four plant associations. Hemicryphtophytes and Therophytes were dominant during spring and monsoon quantitatively hemicryphtophytes were dominant both in spring and monsoon, while Therophytes appeared as a major group in the monsoon. Similarly microphyllous species followed by nanophyllous species were dominant in spring and monsoon in the investigated area.
