Resumo: | The species Lantana camara, commonly used as ornamental, has spread worldwide becoming one of the world's most important weeds. To develop new methods of control of this plant, it is essential to distinguish it from other species of the same genus, and this is usually accomplished through taxonomic studies of fertile samples. Considering the similarity between L. camara and L. radula, and the consequent difficulty in distinguishing one from the other when only sterile samples are available, this work aimed to investigate the use of the anatomical characteristics of the leaves of both species as tools for supporting correct classification. The leaves of L. camara and L. radula were anatomically examined by light microscopy and scanning electron microscopy. The major differences were observed in the petiole, which presented secretory idioblasts in L. camara. Secretory idioblasts were observed in the leaf blades of L. camara and Crystalliferou idioblasts were found in L. radula. Glandular and nonglandular trichomes as well as the abaxial surface are different in each species. Such results can support the strategies aiming at the control of L. camara without interfering with L. radula.
