| The most basic feature of charred grass is its linear structure. Stomata tend
                      to be rectangular. Phytoliths are silica and always include elongated
                      members. A variety of shorter silica phytoliths help identify the family or
                      genera of the grass. Sub-ten-micrometer denticulate structures mark the long
                      edges of epithelial cells. These are generally preserved through combustion
                      by their silica coating. Silica cystolithic hairs are common. Some of these
                      patterns are shared by all monocots and gymnosperms but the details in their
                      structures distinguish them.
