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 ste ms and leaves were prepared and stained by differen tial staining. In palynological study, the pollen were extracted from anther, cetolysed and observed by SEM. The result s 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 palyn ological findings indicated, panporate, tricolporat e, tetracolporate, granulate, microechinate and punctate pollen in studied species.
