Field surveys were carried out to assess the phytodiversity, phenology, leaf size, leaf shape and life form of weed flora of village Sufaid Sung, Peshawar from March 2018 to June 2020. Overall, 95 plant species associated with 31 families have been recorded. Among them 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 each), Chenopodiaceae and Convolvulaceae (3 species each), Apiaceae, Caryophyllaceae, Cyperaceae, Malvaceae and Verbenaceae (2 species each) were the dominant plant families, while the rest of 16 families contributed a single species each. The dominant life form was therophytes (76 species) followed by hemicryptophytes (11 species) and geophytes (8 species). Leaf size of the flora showed that the most dominant leaf size class was mesophyll (38 species) followed by macrophyll and microphyll (18 species each), nanopohyll (15 species), leptophyll (5 species) and a single aphyllous species. Sixty eight species had simple leaves while 26 species had dissected leaves. The findings of the study reflects a detailed phytodiversity and ecological features of the weeds that may be important as reference work for the future ecological, weed management and conservational studies.
