Abstract
Myrcia capixaba and M. forzzae, two new species from the large Neotropical genus Myrcia, are here proposed, described, and illustrated. Both species belong to Myrcia sect. Aguava and are morphologically quite distinct from the other species of the section. Myrcia capixaba occurs in the Atlantic Forest of Espírito Santo and presents a set of features that do not overlap with any other species within M. sect. Aguava: dibrachiate trichomes on the branches, leaves, and inflorescences and externally on the flowers, broadly elliptic to ovate leaves with flat, barely visible secondary venation adaxially, and subterminal panicles. Myrcia forzzae occurs in the Amazon Forest of Mato Grosso and resembles M. gigas, differing in the shorter internodes, vegetative branches and inflorescence rachises densely covered with trichomes (vs. with scattered trichomes or glabrous), and calyx lobes bearing trichomes externally (vs. glabrous).
