Abstract: Present expedition has identified with the different life form categories and biological spectrum of Arasu cement factory forest range, Ariyalur Tamilnadu, India. A total of 66 species belonging to 39 families and 65 genera has been recorded from the area which was categorized in different life forms based on the position of their perennating bud. The phanerophytes (72.72%), were found to be dominant followed by Therophytes (10.66%) and, Hemicryptophytes (4.54%), Helophytes (3.03%), Lianas (9.09%). Biological spectrum on life form was prepared and compared with Raunkiaer s normal biological spectrum as well as the spectra of the adjoining areas prepared by other workers. The study characterizes Thero-phanerophytic type of phytoclimate.
