The wood anatomy of nine species of Eugenia (Myrtaceae) native in Rio Grande do Sul State (Brazil) is presently studied in order to identify diagnostic characters useful to identify genus and species. A great structural homogeneity was observed, reflecting the high number of shared anatomical features. None characteristic is exclusive to this taxonomic group. The value of axial parenchyma arrangement to species segregation is confirmed, as well as the frequency of pores and characteristics of rays. It is not possible to disprove, based on wood anatomy, the inclusion of Hexachlamys in Eugenia, as suggested by Landrum and Kawasaki (1997). Keywords: Wood; taxonomy; anatomy; Myrteae. No presente estudo e investigada a anatomia da madeira de 9 especies sul-rio-grandenses de Eugenia (Myrtaceae), com vistas ao reconhecimento de caracteres uteis a identificacao do genero e especies. Os resultados demonstram uma grande homogeneidade estrutural, fruto do elevado numero de caracteres anatomicos compartilhados. Nenhuma caracteristica ocorre exclusivamente no grupo taxonomico em questao. E confirmado o valor do arranjo do parenquima axial para a separacao de especies, bem como da frequencia de poros e caracteristicas de raios. Nao e possivel contestar, com base na anatomia da madeira, a inclusao de Hexachlamys em Eugenia, como sugerido por Landrum e Kawasaki (1997). Palavras-chave: Anatomia; taxonomia; madeira; Myrteae.
