The leaves are smooth on their upper surfaces, while their undersides are slightly hairy. Its petioles are 3-7.5 millimeters long. Its flowers are arranged in groups of 3 or fewer on a rachis opposite the leaves. Each flower is on a fleshy, slightly hairy pedicel 10.5-17.5 millimeters long. Its flowers have 3, green or brown, oval-shaped sepals that are 2-3 by 2-3 millimeters. The outside of the sepals are densely hairy, while their inner surfaces are smooth. Its 6 petals are arranged in two rows of 3. The oval-shaped outer petals are 12-17 by 13-16.5 millimeters and come to a point at their tip. Both surfaces of the outer petals are slightly hairy. The inner petals are 8.5-10.5 by 5.5-8.5 millimeters. The outside surface of the inner petals is slightly hairy while the tip of the inner surface has long hairs. It has numerous stamens.[3]
