Material and methods: Macroscopic, qualitative and quantitative microscopic characters of E. hirsutum were analyzed. Results: The diagnostic characters of the E. hirsutum were evaluated based on the macroscopical and microscopical characters. Conclusion: The obtained qualitative and quantitative standards will provide referential information for correct identification, purity, stan­dardization and preparation of monograph of E. hirsutum.
