    Abstract: Ten ornamental plants belonging to different families from five sites in Khartoum the capital city of Sudan with equivalent environmental pollution were selected to determine the effect of auto-exhaust pollution on their micro morphological traits. The parameters utilized were numbers of stomata/unit area, numbers of epidermal cells/unit area, length and width of stomata, stomata calculated area, L/B ratio of stomata and stomatal indices from upper and lower surface of the fixed leaf which were found distinctive for each locality.
