Polygonum L., is an eurypalynous genus and four types of surface ornamentation (granulate, granulate-coarsely reticulate, dimorphic exine and variable pattern of ornamentation in polar and equatorial view) have been observed under scanning electron microscope. The variation in exine ultrastructure makes it possible to distinguish four pollen types (Patulum type, Plebijum type, Cognatum type and Avicularia type). Pollen morphology within the genus proved to be useful for the specific delimitation.Read More
