Abstract : Structural variations and histochemical localization of starch, insoluble polysaccharides and lipids were studied in various species including Annona squamosa, Azadirachta indica, Bougainvillea spectabilis, Coccinea indica [Coccinia grandis], Ficus benghalensis, Lantana camara, Mangifera indica, Mimusops hexandra, Syzygium cumini and Tamarindus indica. In normal plants cell walls were undulating, whereas in polluted plants undulation was reduced or walls were straight. Polluted plants also showed reduced stomatal frequency and some variations in stomatal length, width and open pore area. Increases in trichome length and frequency were seen in polluted plants of B. spectabilis and L. camara. Lipid contents of epidermal cells were higher in polluted leaves of some species (Mangifera indica, S. cumini and T. indica), similar to normal in others (Annona squamosa, Azadirachta indica, C. indica, L. camara and M. hexandra), and reduced in others (B. spectabilis and F. benghalensis).
