    Abstract

    The present paper deals with the different life form categories and biological spectrum of the flora of Tons Valley in Garhwal Himalaya. It includes Phanerophytes (29.06%), Nano- phanerophytes (6.47%), Chamaephytes (22.19%), Hemicryptophytes (2.11%), Geophytes (2.64%), Hydrophytes and Helophytes (8.58%), Therophytes (17.83%), Lianas (10.43%), and Epiphytes (O.66%). The comparison with Raunkiaer's normal spectrum depicts 'Hydro- Chamaephytic Phytoclimate.'

    中文摘要

    本文以印度Garhwal喜馬拉雅Tons河谷為研究地區，探討該區所有植物的生活型。結果顯示各類型所佔有的比率分別為高位芽植物（29.06%）、矮高位芽植物（6.47%）、地上芽植物（22.19%）、地表芽植物（2.11%）、地下芽植物（2.64%）、水生植物及沼生植物（8.58%）、一年生植物（17.83%）、木質藤本（10.43%）和附生植物（0.66%）。將此種組成與Raunkiaer的常態生物譜比較後，可將本區之植物相歸入『水生地上芽植物的植物氣候區』。
