The present study was carried out to determine the floristic composition and ecological characterization of the flora of tehsil Sarai Naurang. The floristic diversity of the plant consists of 143 species belonging to 47 different families having 42 dicots and 05 monocots. Poaceae were comprised as the dominant families containing 18 species followed by Brassicaceae, Fabaceae, Asteraceae and Solanaceae. Therophytes were dominant class having 89 species (62.23%) followed by Microphanerophytes 19 species (13.28%), Hemicryptophytes 13 species (9.09%),Chamaephytes 8 species (5.59%), Geophytes 7 species (4.89%), Nanophanerophytes 6 species (4.19%) and Megaphanerophytes have 1 species (0.69%). Leaf size of most plant species was reduced indicating an adaptation to arid climatic conditions. The leaf size showed that Nanophylls size were the dominant followed by Microphyll (40 species (27.97%), Leptophyll (34 species (23.77%), mesophyll (15 species (10.48%), megaphyll (2 species( 1.39%) and macrophyll 1 species (0.69%).
