Pharmacognostical parameters for the leaves of Tridax procumbens L. were studied with the aim of drawing the pharmacopoeial standards for this species. Macroscopical and microscopical characters, physico-chemical constants, extractive values, fluorescence analysis of dry powder and its reaction after treatment with chemical reagents under visible light and UV light at 254 nm and 366 nm were studied. The determination of these characters will aid future investigators in their Pharmacological analyses of this species.
