Using of light and scanning electron microscopy for pollen morphology of some Epilobium (Onagraceae) taxa and Its taxonomic importance

Abstract

In this study, pollen morphologies of eleven species of the Epilobium L. genus belonging to Onagraceae family were investigated under light and scanning electron microscopy. Solutions to taxonomic problems of these species were sought with palynological information. The characteristics of the genus Epilobium L. studied as a result of palynological studies are as follows: It has been determined that their pollen grains have tetrad, angulaperturate, 3-zonoporate (rarely 2,4 porate), suboblate and oblate-spheroidal pollen shapes, and have baculate, baculate-rugulate, and rugulate ornamentation.
