For the first time, micromorphological features of seeds of 6 species of clovers (Trifolium L.) of the Talysh flora, collected from the Lankaran-Lerik region of the Azerbaijan Republic, belonging to 2 subgroups and 4 sections were studied on an electron microscope (SEM). The shape of the seeds, their size, color, surface structure, the shape of hilum and their sizes are important taxonomic features. The structure of seeds of the studied species refers to 4 types: seeds with granular surfaces; seeds with tuberculate surfaces; seeds, which have a surface with crystal-like ledges. Features of the structure of the spores can be used, when specifying the status of subgenera; and sections, the remaining morphological features - when determining species of the genus of clover.
