Different plant has different phytolith. There are three types of phytoliths which maybe used to identify Oryza genera. They are special fan-shape,dumbbell shape parallel to each other along the long axes,and special phytolith from caryopses of rice. In order to research their identified characters for race or even sub -race,the modern caryopses of japonica rice, indica rice and common wild rice (O.rufipogon Griff. ). The conclusions can be summarized as follows: (1 ) The shape of phytolith from calyopses of rice may be described as bumps like mound shape with foamed- netted stripes,and with smooth edges. On projecting part of them, there are double nipples; (2 ) The nipples of cultivated japonica rice are blunter and smaller than indica rice; (3 ) the characteristics of common wild rice are between them.
