Plants are constantly exposed to air, they absorb, accumulate and integrate pollutants confining on their foliar surfaces and show specific response too. The use of plants as monitors of air pollution has long been established, as plants are the initial acceptors of air pollution. Present study was carried out to find out the effect of air pollutants on morphology, physiology and biochemistry of Cassia siamea Lamk. and Cassia Glauca Lamk growing at two different sites of Indore city viz. Scheme No. 78 (Site-I), considered as Low Polluted Area (LPA), in this area there is very low traffic frequency and industries are absent and MR -10 (Site-II) which is Major Road No. 10 of Indore city. There are large number of Industries and heavy traffic frequency in this area, so it is considered as a polluted area. The two species growing at polluted site showed reduction in size of leaf, number of stomata and leaf biomass. Variations in biochemical parameters like chlorophyll in the leaves were found to be pollution load dependent
