A new species, Psidium araucanum Soares‐Silva & Proença (Myrtaceae), endemic to the states of Paraná and São Paulo in south‐eastern Brazil, is described and illustrated. It is most similar to Psidium robustum Mart. ex DC., which it resembles in inflorescence structure and in having medium‐sized open buds and medium‐sized fruits with relatively few, large seeds. Psidium araucanum is distinguished by its off‐white pubescence, which is dense on new growth, and by being a large tree with membranous leaves, brochidodromous venation, long petioles and peduncles, well‐developed, somewhat unequal calyx lobes, and small roundish anthers with few inconspicuous glands. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society , 2008, 158 , 51–54.
