It is a tree reaching 7 meters in height. Its petioles are 5-6 millimeters long. Its mature leaves are hairless, densely covered in warty growths, and shiny on their upper surfaces. The oblong leaves are 18-22 by 4–6.5 centimeters and reach an abrupt 1.5 centimeter-long point at their tip. The leaves narrow at their base to form long wings that run down the petioles. The leaves have 16-18 secondary veins from both sides of their midribs. The secondary veins emerge at near 90° angles from the midribs but curve to join one another 3-5 millimeters from the leaf margin. Its inflorescences have 2-3 green to yellow flowers. The flowers are on pedicels that are 1.5-2 millimeters long. The pedicels have a bract at their midpoint. Its round to oval sepals are warty on the outside, smooth on the inside, and 1.5 centimeters long. Its flowers have two rows of leathery petals. The petals are densely covered in silvery or rust-colored silky hairs on both surfaces. The outer petals are 2.5 by 1 centimeters. The inner petals are 3 by 1.3-1.7 centimeters. Its stamens are 2.7-3 millimeters long.[4][5]
