Opaline Silica in the Leaves of Some Grasses and Sedges of Karachi

S. Shahid Shaukat and G. R. Sarwar

Abstract:
The deposits of silicon in the leaves of several grasses and sedges have been investigated. Shape and distribution patterns of opal phytoliths were examined in the adaxial surface of leaf blades. Dumb- bell shape was found to be most common, such phytoliths were generally arranged in two or three rows. Rod, sphere and saddle-shaped phytoliths were specific for certain species and this can be used as a diagnostic character to delimit such species.
