The upper surface of the leaves are glossy, the undersides are lightly covered in wooly hairs. The leaves have 18-20 secondary veins emanating from its midrib. Its petioles are 3-6 millimeters long, covered in rust-colored wooly hairs and have a groove on their upper surface. Its flowers are on 1-1.5 centimeter long, black peduncles that are covered in white wooly hairs. The peduncles have a triangular bract about a third of the way up their length. The bract is covered with rust-colored wooly hairs. Its calyx has triangular lobes. It has 3 petals that touch, but are not fused, at their margins.
