Total 21 species (15 genera and 12 botanical families) were studied for their foliar anatomy for the first in district Swat, Pakistan because the said plants have multiple diagnostic economic importance and foliar anatomical characters which play a key role in taxonomy. The use of light microscopy has possible in depth to study leaf surface features. Both qualitative (Shape and structure) and quantitative (number, length and width) of epidermis, trichomes and stomatal cells of both leaf surfaces were studied. Mostly the observed traits were similar at both leaf surfaces except few cases i.e stomata were not observed at any leaf surface in totally submerged plants (Hydrilla verticillata, Potamegeton crispus, P. natans, P. perfoliatus), the studied plants were mostly amphistomatic except plant species Sparganium erectum L. which was epistomatic and trichomes were observed in few aquatic plants species which were mostly amphitrichomic except plant species Nasturtium officinale which was hypetrichomic. Aims and objectives of the research project were to explore, document and conserve the aquatic flora of Swat valley and to analyze both quantitative and qualitative characters of their foliar epidermal anatomy.
