The branches emerge just above the middle of the plant. Individuals of this species basal leaves are in groups of threes. The leaflets are thick and leather like with silky hairs on top and wooly hairs on the underside. Each leaflet's ridges are coarsely toothed. Each leaf has a venation pattern of pinnate. The petals grow in groups of five, very common for eudicot plants.
