Two new species of Myrtaceae are described and illustrated. Campomanesia cucullata is a tree from Monte Alegre, Pará, in the Brazilian Amazon. It is most similar to C. lineatifolia, from which it differs by being leafless when flowering, and by having densely congested and very small flowers. Myrcianthes monteucalyptoides is a tree from Tarma, Junín, in Central Peru. It is most similar to Myrcianthes myrsinoides, but the new species differs by a combination of medium-sized, somewhat revolute, broadly-acuminate leaves, and by the solitary, pentamerous flowers with delicate pedicels.
Three new species of Myrcia sect. Gomidesia: M. curtipendula Nic Lughadha, M. aurea Nic Lughadha and M. teresensis Nic Lughadha, from Espírito Santo are described. Their diagnostic characters and habitat are discussed; IUCN categories of threat are assigned.
In this article, which was published in Volume 63, Number 1, pp. 46-50, the illustration of Myrcianthes monteucalyptoides Proença & L. Jenn. (Figure 2) was inadvertently omitted. The figure is shown here.
