Urban vegetation acts as eco-sustainable filter for air pollution of the city. The foliar surface of urban roadside plants acts as a sink for particulate matter depositions which affects the morphological, physiological, anatomical and biochemical properties of leaves. This study aims to find out the morphological and anatomical differences of leaves of Adhatoda vasica and Sambucus hookeri plants growing in two different regions of Kathmandu. Measurement of leaf morphological and anatomical parameters was performed for the comparative study. The study showed that the leaf length, the leaf breadth and the leaf area in Adhatoda vasica were found more in the leaves from ringroad area than the raniban area. The leaf dry mass content was found less in the leaves from ringroad area than the raniban area. In Sambucus hookeri, the leaf length, leaf breadth and leaf dry mass content were found more in the ringroad area than the raniban area. The leaf area in the leaves from the ringroad area was found less than the leaves of the raniban area. The stomata frequency in the peel from lower surface of leaf was found less in the both Adhatoda vasica and Sambucus hookeri from the ringroad area than the leaves from the raniban area. Thickness of the cuticle, length and breadth of the epidermal cell were found more in the leaves of plant growing in the ringroad than the raniban area. The thickness of palisade and the thickness of spongy parenchyma layers were found no different in the both study sites of these two plants.
