A new species of Euphorbiaceae from Amazonian Brazil, Croton faroensis R. Secco, is described. This species is similar to C. paraensis Müll. Arg., but differs in having leaves eglandular or with inconspicuous glands at base, with secondary veins forming obscure archs on the lower surface, in the solitary staminate flowers, filaments with villous trichomes, pistillate ones pedicellate and fruits slightly trigonous at the apex. The systematic position of C. faroensis in relation to the sections of Croton is discussed.
