American Bittersweet (Celastrus scandens) generally bears fruit clusters at the ends of branches, while invasive Oriental Bittersweet (Celastrus orbiculatus) commonly bears fruits along the leaf axils and stems. Correct identification is important because Oriental Bittersweet can spread aggressively and harm native vegetation.
