The Anatomical Examination of Leaf Epidermis of Genus Plantago L. (Ispaghol) from Pakistan
Keywords:Plantago species anatomy, light microscopy, stomata, traditional medicine.
Anatomical observations of 17 different species of Plantago commonly known as Ispaghol (Family Plantaginaceae) obtained from Pakistan, were carried out with the help of a light microscope. The major objective of this study was to evidently describe the anatomical features of these species because there were a large number of overlapping characters between them. Amphistomatic type of leaf epidermis was found. Stomata were anomocytic or anisocytic. Both the upper and lower epidermis cells were double walled, irregular, elongated, oval and tetragonal to hexagonal in shape. Cell walls were found smooth or wavy anticlinal. Epidermal hairs were glandular, simple or multicellular. Stellate types of trichomes were also observed in one member of Plantago genus.
