Abstract :In this electron microscopic study, tbe fine structure of the pollen walls and annuli of Betula medwediewiiB.ege}..,Coryllu8 avellanalj., Carpinus betulus İj., Ostrya carpinifolia Scop insert ignore into journalissuearticles values(Betula- ceae);, Morus alba L. insert ignore into journalissuearticles values(Mofaceae);, Cannabis sativa L., Humulus lupulus L. insert ignore into journalissuearticles values(Cannabaceae);, Myri- opftyZZum spicatum L. insert ignore into journalissuearticles values(Haloragaceae); has been carried out by using T.E.M. The similarities and the differences between the thickness, tbe sculpture and tbe structure of the exine have been shown in tbese families. The electron mîcrographs representatîve for each taxa have been given and the measurements of annuli and exine have been expressed graphically.
