The work aimed to describe the pollen morphology of herbaceous species of Fabales and Poales present on the Massarandupió beach. For this, pollen grains from 12 species belonging to the aforementioned orders were acetolyzed, measured, described under optical microscopy, and photomicrographed. Pollen grains ranged from medium to large. In Fabales, they appeared as isopolar, subprolate to prolate, subcircular amb, and 3-colporate with microreticulate or exine, in Fabaceae, and circular amb, (8)-9-zonocolporate and endocingulate, in Polygalaceae. In Poales, they appeared as heteropolar and isopolar, with granulate, rugulate, finely rugulate, and psilate exine. In Cyperaceae, subprolate, with pyriform contour in equatorial view, heteroaperturate, 1-ana-ulcerate, and inaperturate. In Poaceae they are spherical, prolate spheroidal and circular; monoporate and annullete. The obtained results corroborate the data present in the literature for the studied taxa and have high potential for application in other subareas of Palynology.
