Phytoliths from some grasses (Poaceae) in arid lands of Xinjiang, China

Opal phytoliths, as silicon dioxide inclusions, are abundant in different parts of a plant. It is known that grasses the most representative this respect. The research removed from 25 common grass species arid and semiarid lands Junggar Basin adjacent areas, has been undertaken. visual estimation diversity variability silica cells identification their morphological types (patterns) were also aim our research. Since work preliminary, we have emphasized on cell involved only leaf blades analysis. Drawings revealed cells, characteristic species, provided. sig-nificant phytoliths revealed, well taxonomic similarity at level subfamilies. These data can be used for sediments.
