- Abstract
The present study listed 165 species and two subspecies belonging to 65 families and 139 genera from Tehsil Razar, Swabi District, Pakistan, during 2014 and 2015. There were 134 dicots and 31 monocots species. Cupressus sempervirens was the only gymnosperm and Adiantum caudatum was the only pteridophyte. The families Poaceae (20 spp.), Asteraceae (16 spp.) and Papilionaceae (9 spp.) had the highest number of species. Based on the habitat, 105 species (62.9%) were classified as terrestrial mesophytes and 41 (24.5%) were aquatic species. Twenty species were found in both dry and moist habitats. The free- floating hydrophyte Eichornia crispus was also recorded. Twenty-two (13.1%) species were spiny. Three species were climbers: Asparagus adscendens, Asparagus capitatus subsp. gracilis and Convolvulus arvensis. Cuscuta reflexa and Opuntia dillenii were the only leafless species recorded. Leaf lamina was simple in 121 species (72.5%). There were 27 sciophytes and 130 heliophytes. The flora was dominated by therophytes (67 species; 40.1%), followed by hemicryptophytes (23 species; 13.8%). Leaf- size spectrum was dominated by microphylls (60 species; 36%) and leptophylls (39 species 23.4%).
