Abstract :Seed micromorphology of 20 species of Minuartia L. insert ignore into journalissuearticles values(Caryophyllaceae); that represent 2 different subgenera insert ignore into journalissuearticles values(i.e. Minuartia subgen. Spergella insert ignore into journalissuearticles values(Fenzl); McNeill and Minuartia subgen. Minuartia); were examined using scanning electron microscopy. Some qualitative and quantitative characters such as seed length and width, seed shape, cell shape, and cell ornamentations were studied. The results showed that seed micromorphology might provide useful tools in recognition and separation of Minuartia hamata insert ignore into journalissuearticles values(Hausskn.); Mattf. from other species of sect. Minuartia. Minuartia khorassanica Assadi & Mostafavi, a recently described species from Iran, is another species that micromorphologically was quite different. The species M. juniperina insert ignore into journalissuearticles values(L.); Maire & Petitm., belonging to sect. Acutiflorae insert ignore into journalissuearticles values(Fenzl); Hayek, was completely distinct from other species in this section by having glandular papillae on the cell surface. As a result, seed micromorphology with a few exceptions showed variation and its taxonomic value was significant in distinguishing taxa at the species level.
