This paper presents a detailed pharmacognostical study of the plant drug Hybanthus enneaspermus (L.) F. Muell (Violaceae), an important drug in the Indian system of medicine. The leaf and stem samples were studied using procedures of light, confocal microscopy, WHO recommended physico-chemical determinations and authentic phytochemical procedures. The physico-chemical, morphological, and histological parameters presented in this paper may be proposed as parameters to establish the authenticity of H. enneaspermus and may possibly help to differentiate the drug from its adulterants.
