Aiouea is a Neotropical genus of Lauraceae currently comprising ca. 85 species. Descriptions of new taxa have been frequent in recent years, particularly in Brazil, which currently hosts 35 species, 24 of them being endemic. Based on a review of herbarium material and recent collections, we propose a new species, Aiouea affinis , named for its morphological similarity to Aiouea sellowiana . It is endemic to Brazil, occurring in the mountainous regions of Espírito Santo and Rio de Janeiro. Its putative relationships with other congeners are also discussed.
