Cañandonga ( Cassia grandis L.). Deciduous trees that can become quite large and corpulent, and individuals of 20-30 meters in height are not uncommon, they have a broad and dome-shaped or half-sphere crown, which is possible thanks to a large number of very long and arched branches. The trunk is almost perfectly cylindrical and uniform, with a rather smooth and light gray bark, covered with the horizontal scars left by the branches that have previously come off. These scars disappear as the trunk grows thicker. The strong orange color of the bark on its inner part is very remarkable. The leaves are compound and alternate, perfectly paripinate, with 20 to 40 leaflets, always in even number.
