  It is a tree reaching 15 meters in height. Its young branches are covered in fine rust colored hairs but become hairless when mature. Its hairless, slightly leathery, oblong to lance-shaped leaves are 10-22 by 3.5-7.5 centimeters with pointed tips and bases. The leaves have 9-12 pairs of secondary veins emanating from their midribs. Its flowers occur on solitary, 1-2 centimeter-long pedicels in axillary positions. The pedicels have several small, rounded, basal bracts and a larger, 5 millimeter-long bract midway along its length. The medial bract is covered in rust-colored hairs and has edges that curve backwards. Its triangular sepals are 0.6-1.5 centimeters long. The sepals have pointed tips and are covered in rust colored fine hairs. Its flowers have 6 petals arranged in two rows of three. Its variably shaped petals are 3-5.5 centimeters long with edges that are often wavy.
