F. bidentis leaf was of isobilateral type, and had thicker epidermis cell wall and cuticle, obvious cryptopores, and highly developed palisade tissue, with typical C4-plant Kranz anatomy. The collenchymas and vascular tissue in stem and the aerenchyma in root were well developed. Secretory structure was found in all vegetative organs. According to the analyses of soil physical and chemical properties and relevant ecological factors, F.
