Abstract :The seeds of 32 specimens belonging to 15 species from 2 sections of the genus Epilobium L. insert ignore into journalissuearticles values(Onagraceae Juss.); were studied by both a light and scanning electron microscope insert ignore into journalissuearticles values(SEM);. Seed morphology of the examined specimens exhibits some variation in shape and size. Seed size ranges between 0.97 mm and 2.2 mm in length. They are ovate, oblong-ovate, and narrowly ovate insert ignore into journalissuearticles values(ovate-attenuate);. The results of SEM investigation of seed coat sculpturing also revealed 5 distinct types of surface structure of the seeds, which are mainly correlated to external morphology of the species.
