Buxar forms a district of Patna division in the Ganga Valley and is under intense cultivation and irrigation by an efficient sone canal system. In the present paper life-forms of 540 angiospermic species have been studied and the same have been compared with Raunkiaer's normal biological spectrum and other spectra of the adjoining regions of Ganga Valley. This reveals the dominance of therophytes which indicate that the phytoclimate of the district is therophytic. The area is devoid of its original natural vegetation and the dominance of therophytes is due to the introduction of weeds of cultivation.

Abstract


Buxar forms a district of Patna division in the Ganga Valley and is under intense cultivation and irrigation by an efficient sone canal system. In the present paper life-forms of 540 angiospermic species have been studied and the same have been compared with Raunkiaer's normal biological spectrum and other spectra of the adjoining regions of Ganga Valley. This reveals the dominance of therophytes which indicate that the phytoclimate of the district is therophytic. The area is devoid of its original natural vegetation and the dominance of therophytes is due to the introduction of weeds of cultivation.
