Abstract: The stomata are important anatomical structures present mainly in the plant leaves, being responsible for the regulation of gas exchange. These structures are used in science to identify the climate changes suffered by the plant, as well as being an indicator in the quality control of plant drugs. This work aimed to quantify and characterize the stomata in Siparuna guianensisleaves using two different image capture methods. To do so, scanning electron microscopy and optical microscopy was used, using the epidermis imprinting technique. Stomatal density, stomatal index, polar diameter (PD) and equatorial diameter (ED) of the stomata and the relation between PD/ED were evaluated. The presence of stomas was observed in the epidermis on both leaf faces with predominance on the abaxial side, allowing the leaves to be classified as anfihypoestomatics. There was also a significant difference in the evaluated tests of stomatal density between the abaxial and adaxial faces. The stomata of this species are classified as paracytic.
