Starch grains found within the parenchymatous tissues of the rhizomes of seven Neotropical species of Marattia Sw. (M. alata Sw., M. cicutifolia Kaulf., M. excavata Underw., M. interposita Christ, M. laevis Sm., M. laxa Kunze and M. weinmanniifolia Liebm.) were studied here for the first time. Qualitative optical methods, a microscope provided with polarized light, and scanning electron microscopy have been used. Statistical tests have been applied to the results. Some morphological traits, such as shape, outline, size, and position of hilum are diagnostic at the specific level.
