The morphology of shoot scale and every part of a functional leaf on thedifferent possition of a plant is differrent but their Structure is alike as awhole. Shoot scale of Miscanthus sacchariflorus has the air passage but its func-tional lear and culm have none. Hence, the death of shoot scale is a limitingfactor for the respiration of mature plant. However, the arenchyma is develo-ping much better in the leaf and culm of Phragmites communis than Miscanth-us sacchariflorus. Therefore, the latter could not tolerate the water as theformer. The lamina and the abaxial epidermis of leaf sheath contain a lot of silicacells (150 silica bodies per one 100 cm~2 of a leaf, occupied 15% of a entire leafarea), thus it could not be used as a material of paper making industry. Miscanthus sacchariflorus is a high photo efficiency plant (C_4 plant) whichhas been identified by our observation. This discovery has not been reportedin the past work.
