It is a tree reaching 15 meters in height. Its leathery leaves are 10-18 by 4-8 centimeters and their tips come to a shallow point. The leaves are green on their upper side, brownish below, and smooth on both surfaces. The leaves have 8-15 pairs of secondary veins emanating from their midribs. The leaf margins have shallow rounded teeth. Its petioles are 1-3 centimeter long. It has inflorescences of 25-50 flowers on peduncles 2-8 centimeters in length. Its flowers have 5 sepals. The outer pair are elliptical and 6 by 3.3 millimeters. The inner 3 are 8 millimeters long. The flowers have a corolla with 5 lobes; each lobe is 5-9 by 3.5-6 millimeters. Its flowers have around 30-80 stamens that are 0.5-0.85 millimeters in length. Each flower has a 4-5 chambered ovary. Its flowers have 3 styles that are 9 millimeters long, and fused at their base for the last 1-2 millimeters.[2][3]
