ABSTRACT
The current study was performed 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 families including 42 dicots and 5
monocots. Poaceae was the dominant family containing 18 species followed by
Brassicaceae, Fabaceae, Asteraceae and Solanaceae. Therophytes were dominant class
having 89 species (62.23%) followed by Microphanerophytes with 19 species (13.28%),
Hemicryptophytes with 13 species (9.09%), Chamaephytes 8 species (5.59%),
Geophytes 7 species (4.89%), Nanophanerophytes with 6 species (4.19%) and
Megaphanerophytes with 1 species (0.69%). Leaf size of most plant species was reduced
indicating an adaptation to arid climatic conditions. Nanophylls had the largest leaves,
followed by Microphylls (40 species, 27.97 %), Leptophylls (34 species, 23.77 %),
Mesophylls (15 species, 10.48 %), Megaphylls (2 species, 1.39 %), and Macrophylls (1
species 0.69 % ).
