Background: Croton cordiifolius Baill. is popularly known as “quebra-faca” in the Brazilian Northeast and is used to treat general inflammation, pain, and gastrointestinal disturbances. Objective: This paper aims to study the anatomical characteristics of C. cordiifolius. Materials and Methods: Cross-sections and paradermic sections of root, stem, petiole and leaf blade were obtained by hand and submitted to double staining with astra blue and safranin process for the anatomical study. Maceration was performed according to the method of Jeffrey. Results: The secondary root has peridermis, parenchymatic cortex, collateral vascular system surrounded by sclerenchyma. The secondary stem has peridermis, cortical region with lignified cells, isolated groups of fibers, laticifers, prismatic crystals, druses and starch. The vascular system of the stem is bicollateral. The petiole and the leaf blade have stellate, simple and glandular trichomes. The leaf blade is hypostomatic, with paracytic stomata. The mesophyll is isobilateral and the midrib shows a concave-convex contour. Laticifers occur in stem, petiole and leaf blade. Prismatic crystals and druses are found in all organs analysed. Through the maceration it was possible to identify the type of vessel elements. Conclusion: The anatomical features are useful for differentiation of other species of Croton and provide support to their quality control.
