PHYTODIVERSITY AND ECOLOGICAL FEATURES OF WEED SPECIES OF SUFAID SUNG, PESHAWAR

Field surveys were carried out to assess the phytodiversity, phenology, leaf size, leaf shape, life form and ethnobotany of weed flora of village Sufaid Sung, Peshawar from March 2017 to June 2019. Overall, 95 species have been reported associated with 31 families. Dominant families were Poaceae (22 species), Asteraceae (10 species) followed by Amaranthaceae and Papilionaceae (6 species each), Brassicaceae and Polygonaceae (5 species each), Euphorbiaceae and Solanaceae (4 species), Apiaceae, Caryophyllaceae, Cyperaceae, Malvaceae and Verbenaceae added 2 species, Chenopodiaceae and Convolvulaceae contributed 3 species, Apiaceae, Caryophyllaceae, Cyperaceae, Malvaceae and Verbenaceae added 2 species while the rest of 16 families contributed a single species each.
