Resumo

A phylogenetic analysis of plastid rbcL sequences indicates that Pellaea flavescens from Brazil is nested within the Old World species Pellaea viridis. The morphology of these two species is similar and P. flavescens is here considered to be a synonym of the older P. viridis. This fern may have been introduced to and subsequently naturalized in Brazil or, alternatively, the natural result of long distance dispersal. (AU)
