Micromorphological characters of pollens and seeds of six sect. Daghestanica (Tscholok.) N.Friesen species were observed and analyzed by using light microscopy (LM) and scanning electron microscope (SEM), and the taxonomic value and the significance of evolutionary biology of these characters were discussed for the first time. These studies provide some theoretical support for interspecific taxonomy. Study results showed that: (1) the pollen shapes of Daghestanica species were prolate with the size of (17.84-29.84) μm × (12.23-19.18) μm, and the equatorial view shapes were elliptical, the polar view shapes were round, bilateral symmetry. The exine ornamentation were rugulate and reticulate. The pollen exine ornamentation and perforation characteristics among the six species were significantly different. (2) The species with largest pollen size was A. rude, which was accompanied with longer polar axis than other congeners, and the species with smallest pollen size was A. herderianum. (3) The seeds of the Chinese Allium sect. Daghestanica were ovate and the ornamentation of seed coat is scalariform. The cell is polygon, cellular arrangement is relatively loose with verrucate on the periclinal walls, anticlinal walls are straightarched. (4) The cell shape, arrangement and secondary of convex testa cells have predominant differences among species. So differences of morphorlogical characters in seeds and pollens can provide some evidence for classification of the Chinese Allium sect. Daghestanica species.
