Its leaves and stem are analyzed morphologic and anatomically, freehand sectioned in cross-section and longitudinal section, and were stained in astra blue and safranin. Petiole and midrib base present 15-20 vascular bundles. The blade is hypostomatic, dorsiventral and shows staurocytic stomatal complex, subepidermis and oil idioblasts.
