The present study is insight into foliar epidermal anatomy for characterizing species and their utility in the taxonomic separation of certain taxa of family of Vitaceae from Pakistan. The studied foliar micromorphology of 5 species; Parthenocissus semicordata (Wall.) Planch, Parthenocissus tricuspidata (Siebold & Zucc.) Planch, Ampelopsis vitifolia (Boiss.) Planch. subsp. hazaraganjiensis Nazim & Qaiser, Cissus trifoliata (L.) L., and Cissus quadrangularis L. was analysed and documented using Light microscopy (LM) for both qualitative and quantitative characteristics. Epidermal cells observed were either polygonal or irregular shaped, with straight or undulate anticlinal walls. Two types of stomata observed were paracytic and anomocytic with elliptical shaped guard cell all the studied species except adaxial surface of Parthenocissus semicordata, Parthenocissus tricuspidata and Ampelopsis vitifolia subsp. hazaraganjiensis. Trichomes were conical shaped, non-glandular either unicellular or multicellular. The quantitative parameters studied were size (length and width) of stomata, subsidiary cell, guard cells, stomatal pore, stomatal complex, trichomes. There was much variation in the size of all the parameters investigated. These anatomical features may help in the discrimination of studied taxa and are of much significance for the plant taxonomist in the correct identification of taxa.
