Abstract :Six grass species of Lamarckia aurea insert ignore into journalissuearticles values(L.); Moench, Lolium persicum Boiss. & Hohen. ex Boiss, Poa annua L, Festuca arundinaceae Schreb, Aegilops cylindrica Host and Hordeum murinum L. were investigated for their foliar micromorphological and palynological characters through light and scanning electron microscope for their taxonomic importance. Different foliar micromorphological characteristics i.e. silica bodies, macrohairs, microhairs, stomatal number, size, stomatal shape, stomatal density insert ignore into journalissuearticles values(SD);, epidermal cell number, epidermal cell density insert ignore into journalissuearticles values(ECD);, subsidiary cells, short and long cells were examined and observed on both abaxial and adaxial surfaces. The pollen characters i.e. pollen type, polar and equatorial view and diameter along with some other characters were also observed. These foliar morpho and palynological characters were found significant in the delimitation of these species
