Eugenia rotundifolia Casar., Myrtaceae, occurs in the sandy coastal environments of Rio de Janeiro and Espirito Santo States. To the best of our knowledge, E. rotundifolia was not included in ethnobotanical and nor in pharmacological research, but its leaves are sold in a public market of Rio de Janeiro City as "abajuru", the common name for Chrysobalanus icaco L., Chrysobalanaceae. C. icaco, in contrast, has been studied and its medicinal effects reported. Since E. rotundifolia is often sold in the public market as "abajuru," this paper describes and compares the leaf anatomy and morphology of E. rotundifolia with C. icaco, previously described in the literature, in order to provide tools for the authentication of commercialized "abajuru." Phyllotaxy; texture; color; margin; midrib prominence; stomata type; type and shape of midrib and petiole vascular bundle; the presence of marginal vein, secretory cavities, which are seen as translucent dots, and overlying cells only in E. rotundifolia; and the presence of trichomes, periclinal divisions in adaxial face epidermis, hypodermis and vascular bundle extensions only in C. icaco were found to be the most distinguishable diagnostic characters.
