The macroscopic and microscopic details including powder were studied following the standard pharmacopoeial procedures. Results: Macroscopically leaves are pubescent with petiole containing small stipular spines. Microscopically, transverse section of the petiole consists of parenchyma, ceratenchyma and vascular bundles; midrib comprises of parenchyma, collenchyma and vascular bundles and lamina contains epidermis, differentiated mesophyll cells and embedded vascular bundles. Quantitative Microscopy was carried out and the epidermal number, stomatal number, stomatal index, vein islet number, vein islet ratio, palisade ratio were recorded. Powder microscopy of leaves showed the presence of wavy epidermal cells, stellate trichomes, parenchyma, groups of thick walled fibres, tracheids, spiral vessels and numerous stone cells.
