Abstract
S ocratea exorrhiza (Mart.) H. Wendl. is a palm tree that occurs in significant abundance in lowland forests of the Amazon region due to its root system adapted to flooded environments. However, with the sheet the organ that more changes in response to environmental change is proposed in this study to characterize the leaf structure of S. exorrhiza , aimed at generating useful information to better understand the anatomical characteristics of this body, in the occurrence of natural conditions of species. For this, samples were submitted to the usual techniques in plant anatomy. The regions of the leaf have different structures. The sheath is presented dorsiventral with papillose epidermis, air spaces, canals with septa and crystal raphides, the petiole and rachis exhibit a peripheral region and other spinal cord, with vascular bundles surrounded by sheaths amiliferous. The pinna is amphistomatic, with waxy streaks on the walls of guard cells, trichomes in the form of T, filamentous and branched. In the mesophyll, three types of vascular bundles: primary, secondary and tertiary, the border along the pinna has tapered form, orthorhombic and revolute. From the results it is concluded that, in general, the leaves of S. exorrhiza have characteristics common to Arecaceae. However, striking feature have been observed that may be unique to the species. Keywords : Palm; pinna; trichomes; secretory ducts; floodplain forest.

Summary
Já nas regiões intercostais da superfície abaxial, as células apresentam formato retangular, paredes retas, alongadas e espessas (Figura 2B), orientadas em fileiras longitudinais ao longo do eixo da pina e cobertas por uma camada de cera epicuticular. Tomlinson (1961) citou que, geralmente, os tricomas são ausentes na lâmina foliar das palmeiras, porém classificou cinco tipos (I-V), não mencionando, entre estes, algumas tipologias encontradas em Socratea exorrhiza, como os ramificados com até três braços e a forma “T”.
