A List of plant species of Bajaur District was set on the basis of field trips conducted in different parts of the year 2018, mostly in, summer, monsoon and winter. The flora comprised of 167 plant species belonging to 40 families. The leading families are Lamiaceae, Solanaceae and Asteraceae, which have 16 species, followed by Mimosaceae and Euphorbiaceae, 11 Zygophyllaceae 8 and Moraceae, with 7 species. Each of the Poaceae, Rhamnaceae, Verbenaceae Papilionaceae, Capparidaceae, Amaranthaceae and Apocynaceae had 3 species, while Buxaceae, Asclepiadaceae, Nyctaginaceae, Oleaceae, Plantaginaceae, Polygonaceae Cannabinaceae, Celastraceae, Cucurbitaceae, Cyperaceae, Liliaceae, Acanthaceae, Aclepidaceae, Meliaceae, Sapindaceae and Sapotaceae had 2 species each.
