Microscopical Transverse section of the leaf shows upper epidermis, a layer rectangular cells in Sectionsl view or slightly wavy-walled cells in surface view,stomata absent. Mesophyll composed of 2 to 3 layers of palisafe and several layers of spongy cells withidioblasts containing calcium oxalate prismatic crystals;fibrovascular bundle and schizolysigenous oil cavity containing oil droplets located in spongy tissues. Fibrovascular bundle composed of fibre surrounding amphicribal vascular bundle; xylem composed of spiral,reticulate,and border-pitted vessels and xylem parenchyma some of which containing prismatic crystals of calcium oxalate. Collenchyma,2 to 3 layer of cells, located in the central part of midrib beneath lower epidermis. Lower epidermis,a layer of rectangular cells in sectional view or wavy-walled cells in surface view with anomocytic type of stomata (Fig. 2a)
Citrus Hystrix Leaf in powder possesses the diagnostic microscopical characters of the unground drug(Fig.2a)
