The anatomical description of the branch xylem of G. elata, I. nayana and S. orinosensis of the Arboretum “El "Huayo" of the CIEFOR Puerto Almendra Iquitos, was carried out in this study. The methodology used was that of Valderrama (2008), which allowed the description based on the qualitative and quantitative anatomical characteristics of the branch xylem. Results shows that G. elata and I. nayana have an undefined test, while S. orinosensis has a bitter taste. G. elata has large diameter pores (53%); I. nayana and S. orinosensis have medium diameter pores (53%). The three species have medium brightness, straight grain and medium texture. G. elata has undifferentiated figure, while I. nayana and S. orinosensis have differentiated figure of overlapping arc type. G. elata has very long rays (43%), while I. nayana has medium rays (43%) and S. orinosensis has extremely very short rays (63%), G. elata and I. nayana have parenchyma of the apotracheal type, while S. orinosensis has parenchyma of the apotracheal type in bands and unilateral aliform paratracheal bands.
