First true leaves are alternate and irregularly shaped with toothed margins. All subsequent leaves are lobed at least three times and are arranged alternately along te stem. Flower stalks arise from the leaf axils and consist of five petals that are pale yellow to white in color with a purple base. The five sepals resemble a membranous bladder with distinctive dark green veins.
