Description.
It is a tree that reaches 5 meters in height. Its branches have lenticels. Its leathery leaves are 14-19.5 by 5.5-7.5 centimeters and have pointed tips. The leaves are hairless when mature. The leaves have 12-18 pairs of secondary veins emanating from the central rib. Its petioles are 1.5-5 millimeters long with a groove on their upper side. Inflorescences are organized on slightly hairy peduncles 20-35 millimeters long. Each inflorescence consists of up to 10 flowers. Each flower is on a densely hairy pedicel 2-4 millimeters in length. The flowers are unisexual. Its flowers have 3 oval-shaped sepals, 0.8 by 1 millimeters, that have blunt tips. The outer surface of the sepals is densely hairy while the inside is smooth, and their margins have very fine hairs. Its 6 petals are arranged in two rows of 3. The outer petals are white or yellow-green and 2 by 2 millimeters. The outer petals are smooth on the inside and densely hairy on the outside. The inner petals have a 0.9 millimeter claw at their base and a 2-3.5 by 1.5-2 millimeter blade. The inner petals are smooth on their upper surface and densely hairy on their lower surface. Male flowers have up to 26 stamens that are 0.5-0.6 millimeters long. The gynoecium consists of 1-2 unfused carpels (monocarps). Fruit are attached to 30-40 millimeter peduncles by 8-9 millimeter pedicles. Mature monocarps are orange, hairy, wrinkly ellipsoids, 17-21 by 13-19 millimeters. Each monocarp has 6-8 wrinkly seeds, 8.5-13 by 6-8.5 millimeters.
