【 摘 要 】

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