Nelsonia canescens (Lam.) Spreng. (Acanthaceae), a well-known plant in traditional systems of medicine, known as "Bada Rasna" by the traditional practitioners of Odisha, is being used as Rasna for managing pain and inflammation. The detailed macroscopic and microscopic characters of the plant, except its root, are lacking. Hence, it was thought worth to study the leaves of the plant for its detailed morphological and microscopical characters, by following the standard pharmacognostical procedures. The study shows the presence of diacytic stomata in the lower epidermis of lamina, microsphenoidal and prismatic crystals of calcium oxalate in the mesophyll cells, simple and glandular trichomes. The observed major diagnostic characters of the leaf may find useful for its standardization.
