Its bark is rough and varies from white to gray. The surface of the leaves is bright green and dark, but pale green below. Oval and very narrow, they are bent at the ends. The shrub has small unisexual or bisexual flowers with 4 white petals that are clustered at the tip of the stem or at the base of the upper leaves. Its fruits are small green drupes that turn black when ripe.
