A new brazilian species, Ouratea javariensis sp. nov., is described from Amazonas state. Morphological comparisons with O. verruculosa Engler from Amazonas too, but growing along the Rio Negro, are made. Ouratea javariensis differs from O. verruculosa by the margin of the leaves denticulate and a few undulate, and by the inflorescence erect 15-16 cm long, with 5-6 ramifications, when it is curved and has 5-10 cm long in O. verruculosa.
