The Melia composita Willd. [family Meliaceae] was studied to fix the parameters for pharmacognostical standards.The present investigation deals with macro and microscopical characters of leaf along with studies of Histochemical colour reaction leaf constant like vein-islet number, vein termination number, stomatal number, stomatal index and palisade ratio and also studied physical constants like ash values and extractive values
