leaves like Millingtonia hortensis, do not hold dust to the same degree Azadiracta indica, Melia rubia compared to horizontally arranged leaves of Grevillea robusta, Delonix regia, Anacardium bearing stiff, horizontal and elevated leaves with rough and occidentale, Tamarindus indica species hairy surface which hold large amount of dust particles. Similarly drooping leaves and branches have higher chances of dropping down dust during disturbance by agents like wind, animal etc. Free hanging leaves as well as swirling leaves are the main morphological characteristics of dust escaping efficiency as in Dalbergia sisso, Eucalyptus etc. Certain species acquire a peculiar type of leaves which are devoid globulus, Acacia auriculiformis of leaf damage and hurt. Such modification of leaf surface is highly favorable in dusty environment like stone quarry.
