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 (Betula- ceae), Morus alba L. (Mofaceae), Cannabis sativa L., Humulus lupulus L. (Cannabaceae), Myri- opftyZZum spicatum L. (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.
