The leaves of R. chalepensiscommonly known as fringed rue, is reported to be used as a substitute owing to similar morphology in dried form.

Results: Macroscopically leaves are different colored with dissimilar shape, in microscopic study R. graveolensshowed toothed lamina with glandular trichomes while R. chalepensisshowed lamina without trichomes. Quantitative microscopy of both species was carried out and the epidermal number, stomatal number, stomatal index, vein islet number, vein islet ratio, palisade ratio was recorded. Powder microscopy of R. graveolensleaves showed the presence of pitted and spiral vessels while R. chalepensisshowed annular and spiral vessels.Conclusion: The study provides the characteristicsfeatures to distinguish R. graveolensfrom R. chalapensis.
