ABSTRACT

With additional data from specimens not studied by previous workers, the confusing Simaba guianensis compex was re-analized. Simaba polyphylla is recognized as a distinct species and two subspecies of S. guianensis are maintained. Simaba polyphylla, S. guianensis ssp. guianensis, and S. guianensis ssp. ecaudata are keyed, described, and illustrated and specimens examined are cited for each. Specimens of S. guianensis ssp. ecaudata show great morphological diversity but can be separeted into three groups. Further collecting may provide information that shows these groups to be worthy of separate taxonomic status.

RESUMO

Dispondo-se de dados obtidos de amostras não vistas por outros pesquisadores o complexo de Simaba guianensis foi reanalizado e dividido em S. polyphylla e S. guianensis, este último com duas sub-espécies. Apresenta-se chaves, descrições e ilustrações e amostras estudadas para S. polyphylla, S. guianensisssp. guianensis, e S. guianensis spp. ecaudata. Exsicatas de Simaba guianensisssp. ecaudata exibem ampla diversidade morfológica que permite reconhecer três grupos. Coletadas adicionais talvez providenciarão informações indicando que estes grupos merecerão status taxonômico.
