Title

Study of the life form and the biological spectrum of Umananda River Island, Guwahati, Assam, India - a tool for characterization of the phytoclimate

Abstract

The present paper deals with the characterization of the phytoclimate of the Umananda river island in Guwahati, Assam with the help of Raunkiaer’s life form and biological spectrum method. A total of 128 species of vascular plants belonging to 122 genera and 60 families have been reported from the island. All the plant species are categorized into different life form based on the position of their perennating bud. Therophytes (Th. = 32.03%) and Mesophanerophytes (Mesoph. = 20.31%) were found to be dominant followed by Chamaephyte (Ch. = 11.72%), Microphanerophyte (Microph. = 9.38%), Hemicryptophytes (H.Cr. = 7.03%), Lianas/climbers and Geophytes (5.47%), Mega and Nanophanerophyte (3.13%) and Epiphytes (2.34%). On the basis of the life form categories, biological spectrum was prepared and compared with Raunkiaer’s normal biological spectrum. On comparisons with Raunkiaer’s normal spectrum, the area depicts Thero-phanerophytic type of phytoclimate.
