In the present research study, a comprehensive floristic list of Baranai Valley, Madyan, District Swat, Pakistan was carried out during 2022-23. A comprehensive enumeration documented a sum of 197 vascular species, exhibiting botanical diversity across 76 distinct families. Pteridophytes were manifested by 8 species classified under 6 families, Gymnosperms displayed representation through 2 families comprising 07 species, Monocotyledons showcased 26 species dispersed among 08 families, and Dicotyledons exhibited a more significant presence, encompassing 156 species spanning 60 families. Poaceae, Lamiaceae, Rosacaeae were the dominant families with 12 species each followed by Asteraceae, Papilionaceae, with 09 species each and Solanaceae 8 species. Herbs asserted their dominance with a numerical preeminence of 140 species, succeeded by trees encompassing 28 species, shrubs contributing 21 species, and climbers represented by a more modest count of 08 species. The life form spectra delineated Therophytes as the prevailing category, exhibiting a prominence with 70 species, succeeded by geophytes comprising 37 species, Nanophanerophytes accounting for 35 species, Hemicryptophytes totaling 23 species, and chamaephytes represented by a more modest count of 08 species.
