ABSTRACT
NEW INVESTIGATIONS ON THE MORPHOLOGY OF THE TWO BRAZILIAN SPECIES FOR THE GENUS SESSEA (SESSEA REGNELLI TAUB. AND SESSEA BRASILIENSIS TOLEDO) HAVE MADE POSSIBLE THE RECOGNITION OF SOME MORPHOLOGIC CHARACTERISTICS WHICH ARE RELEVANT TO THE DIAGNOSIS OF THE SPECIES AND THE CONCEPTUALIZATION OF THE GENUS. THE ANALYTICAL COMPARISON BETWEEN SESSEA AND CESTRUM LED TO A NEW HIERARCHIC POSITION FOR THE GENUS SESSEA. THE PRESENT PAPER ALSO INCLUDES A KEY TO THE BRAZILIAN SPECIES. NEW OCCURRENCES IN THE COUNTRY ARE REPORTED.
