Abstract:
Epidermal silica cells have been studied in fifteen species belonging to seven genera of Cyperaceae collected from places in and around Lahore. They are present in the epidermis of stem and leaf, being more common in older parts. They are invariably located in regions outside the subepidermal fibre strands and are characterized by conical silicified processes on their inner tangential walls. Directly below the process, the wall is thickened in the form of a pad, while the outer tangential wall is comparatively thin and raised. A silicified process consists of a hallow hat-shaped body, pointed at the top. When seen in surface view, there are one to many circular rather ellipsoidal silicified processes in a cell. It was also found that the silica bodies are more common in the species, growing on sandy soil.
