RESUMO

The genus Calea belongs to the tribe Heliantheae and presents about 125 species. Calea serrata, popularly known as erva-de-cobra, chá-amargo and quebra-tudo, is an endemic species found in southern Brazil and is used in traditional medicine to treat ulcers and livers problems. The present work aimed to study the pharmacobotanical characters of leaves and stems of C. serrata for quality control purposes. The plant material was processed according to standard methods of light and scanning electron microscopy. Glandular capitate-stalked and capitate-sessile, uniseriate multicellular non-glandular trichome with tapered apical cell, conical non-glandular trichome, isobilateral mesophyll, secretory ducts near the endoderm and circular shape with six ribs in the stem were important characters, which contributed to the identification of the species.
