THE GENERA OF MYRTACEAE IN BRAZIL - AN ILLUSTRATED SYNOPTIC TREATMENTAND IDENTIFICATION KEYS

A synoptic treatment of the 23 genera of Myrtaceae in Brazil and keys for their identification are provided, including a general key to all genera, a key to the subtribes, and keys to the genera of each subtrib e. Four commonly recognized genera that we consider to be of uncertain status are provisionally treated as segregates of large related gener a: Marlierea and Gomidesia with Myrcia; and Hexachlamys and Calycorect es with Eugenia. Important characters of the inflorescence, calyx, ova ry, placenta, ovule, fruit. seed, and embryo are discussed and illustr ated. Information provided for each genus includes concise description s, geographic distribution, approximate number of species, and compari sons to related genera. Families that might be confused with Myrtaceae are briefly discussed. A new combination, Mosiera prismatica (D. Legr and) Landrum, is made.
