Abstract

In present study, anatomical and palynological characters of Rumex species in NE Iran were examined. For anatomical study, manual cross sections of fresh and dried stems and leaves were prepared and stained by differential staining. In palynological study, the pollen were extracted from anther, acetolysed and observed by SEM. The results of anatomical research showed, annular collenchymous tissue below the epidermis layer, different shape of vascular bundle, sclerenchymous strands around the vascular bundles in stem, dorsi-ventral mesophyll and continuous and discontinuous vascular bundles in leaves. The palynological findings indicated, panporate, tricolporate, tetracolporate, granulate, microechinate and punctate pollen in studied species.

Keywords: Anatomy, Iran, pollen, Polygonaceae, Rumex.
