The leaf of Pseudo-curaica from three different environment exist the s

But the different deepness of water have influence on the anatomical structure of leaf, the characters as follow: along with increase of moisture, the number of vascular bundles, the thickness of vascular bundles and leaf, the diameter of vessel and air-cavity are also increased. All of the structural change are plants character which adapt to plashy environment. Key wordsPseudo-curaica three environments stem comparative anatomy
