Scanning electron micrograph of particulate matter on leaves: (a) and (b) Kerria japonica; (c) and (d) Sophora japonica; (e) and (f) Philadelphus pekinensis; (g) and (h) Gleditsia sinensis; (i) and (j) Prunus persica 'Atropurpurea.' (a), (c), (g), (e), and (i) show particles at a 20-μm scale, while (b), (d), (f), (h), and (j) show particles at a 100-μm scale.
