Roselia has leaves extending from its shoulders like epaulettes, and a pointed streak of yellow extends from its neck down the forefront of its leaf skirt. Visible from the back is a small stretch of yellow coloration around its neck much like a collar. Roselia also has three thorns on top of its head.
