A study was conducted to assess the floristic composition of Lala Kalay District Peshawar during 2016-17. The floristic diversity consisted of 80 species belonging to 45 families. Asteraceae and Solanaceae were the dominant families each comprised 6 species, followed by Poaceae and Euphorbiaceae (5 species each), Moraceae and Rosaceae (each with 4 species). The rest of the families contributed 1-2 species. Biological spectrum reflected that Therophytes was the dominated life form that contributed 30 species (37.5%), followed by Microphenrophytes (16 species, 20%), nanophanerophytes (14 species, 17.5%) and Caemephytes (8 species, 10%), geophytes (7 species, 8.75%), Phanerophytes (3 species, 3.75%) and Hemicryptophytes (1 species, 1.25%). The leaf spectrum revealed that Microphyll was dominated in the area with 33 species (41.25%), followed by Mesophylls (20 species, 25%) and Nanophyll (18 species, 22.25%),while Leptophylls and Megaphyll were less important (each with 4 species, 5%). Data on biological spectra can be utilized for management of the studied habitat and further assessment for carbon footprint and many other studies.
