Present investigation has been carried out on the morphological characters of 3 species of the genus Vernonia Schreb., such as Vernonia cinerea Less., Vernonia diffusa Less., Vernonia gracilis Kunth. Of the tribe Vernonieae. This character plays a paramount role in isolation of taxa at the species level. Morphological features of the apical part, surface hairs, location of vascular trace, structure of carpopodium and their cellular arrangement, pappus bristles of cypselas are taxonomically significant. An indented dichotomous key is provided on the basis of macro-morphological features of cypselas for identification of studied species.
