Comparative study of pollen and seed morphology of three species of Rhododendron L.subsect.Rhodorastrum (Maxim.

) Cullen (Rh.dauricum spidertattooz.com L., Rh.

mucronolatum Turcz., Rh.sichotense Pojark.

) is performed.Results of discriminant analysis of the total of morphometric characters of pollen and seeds have proved the distinctness of all three species from each other.Differences of polen are observed in the type of sculpture (granulate, rugulate, princess polly dresses long sleeve microrugulate) and in the diameter of tetrads.

The coefficient of elongation of the exotesta cells is established as a valuable morphometric character.
