Abstract: The present research was carried out to establish detailed pharmacognosy of Hibiscus schizopetalus (Mast) Hook and Hibiscus rosa sinensis L., which included macros copy, microscopy, physico-chemical parameters and fluorescence analysis of flower and leaf samples of both plants. It was observed that macroscopic and microscopic characteristics were diagnostic features and can be used for distinction and identification of these closely related plant species. Physico-chemical parameters revealed that in investigated plant species total ash value, acid insoluble ash value and water soluble ash value was observed tornbe higher in flower of H. rosa sinensis (20.35 % w/w, 4.01 % w/w, 6.00 % w/w respectively) whereas moisture content was found to be higher in H. schizopetalus.
