The anatomical characters were numerically analyzed by cluster analysis (CA) and principal component analysis (PCA). Although general stem and leaf anatomical traits are very similar, some anatomical characters such as the ratio of cortex/diameter of stem and phloem/xylem, the average row number of collenchyma, palisade and spongy cells, and stomata index are more important for delimiting the investigated taxa. These results indicated that anatomical features would be useful in separating the examined species.
