A new species of Bertolonia (Melastomataceae; Bertolonieae) endemic to the Brazilian Atlantic Forest is described and illustrated. Bertolonia organensis is known from only one locality in the Serra dos Órgãos National Park, state of Rio de Janeiro. The main diagnostic characteristics that distinguish B. organensis are the leaves with bullate adaxial surface and foveolate abaxial surface, cordate base and seven acrodromous veins, petiole and hypanthium glandulose-punctate, setulose and setulose-glandulose, the external calyx lobes erect, thick, narrow-triangular, apex acuminate-glandulose, margin entire, not ciliate, and the anthers connective dorsally appendaged, trilobed or with an acute calcar. Comparisons with similar species, geographic distribution and habitat are presented for the new species, as well as a key to identify all Bertolonia taxa known from the state of Rio de Janeiro. Bertolonia organensis is classified as Critically Endangered (CR).

A new species of Lippia endemic to the Brazilian Atlantic Forest is described and illustrated. Lippia diversifolia is currently known from the inselbergs of Espírito Santo and Rio de Janeiro and is characterized by markedly tetragonal branches, of which the opposed sides are densely strigose and the other glabrescent, with indument alternating in the subsequent internode, leaf blade cartaceous to coriaceous, adaxial surface strigose, abaxial surface tomentose or strigose, peduncle 3.5–9 cm long, bracts strigose with apex acute, inconspicuous calyx, and white sessile glands along the whole plant. We provide field photographs, distribution map, conservation status and a table with the main characters that distinguish it from Lippia rubella, which is a morphologically similar species.

We describe and illustrate Behuria lumiarensis, a new species from the state of Rio de Janeiro, Brazil. It has been collected only once in montane vegetation in the Municipality of Nova Friburgo. The new species can be recognized by the combination of leaf blades with adaxial surface covered with sessile glands and abaxial surface moderately covered with stalked glands only on the veins, hypanthium sparsely covered with stalked glands, a large calyx tube with narrow sepals that are not apiculate in the apex, small petals, and glabrous ovary apex.

We present a new species, a new synonym, the resurrection of a species that has been synonymized before, updates on the distribution of three species, and lectotypifications for two species of Meriania from the Brazilian Atlantic Forest. Meriania baumgratziana is a new species apparently restricted to montane areas in the western portion of the state of Rio de Janeiro. It can be recognized by the sessile to subsessile leaves, these lanceolate, elliptic lanceolate or oblong-lanceolate, with cordate to cordulate, amplexicaul bases (seldom narrowly round), the abaxial surface in young leaves with the union of the primary and the inner pair of secondary veins with a membrane forming pocket domatia, these with trichomes emerging from the inside, then in older leaves the membranes frequently enlarged, globular, these hypertrophied structures sometimes caducous, or easily removed by friction, and by the pendulous inflorescences with 4-merous flowers. Meriania paratyensis Chiavegatto & Baumgratz is synonymized under M. sanchezii R.Goldenb., which in turn is resurrected from what we understand as a mistaken synonymy under M. paniculata DC. We present a discussion and illustrations of leaves and fruits, in order to explain these changes and compare all these three species, plus a fourth similar species, M. glabra (DC.) Naudin. The distributions of Meriania calyptrata (Naudin) Triana and M. sanchezii are updated, the former with the inclusion of specimens collected in the western tip of the state of Rio de Janeiro (it was previously recorded only for eastern São Paulo), and the latter in the exactly opposite way, with new records from Rio de Janeiro added to the previously known specimens from São Paulo. Finally, lectotypes are designated for Meriania calyptrata and M. glabra (DC.) Naudin (this superseding a previous, unnecessary designation of a neotype).

Miconia goldenbergiana, a new species from the Atlantic Forest in southeastern Brazil, is described and illustrated. The new species have been extensively collected since the end of the XIX century but have been confused with M. budlejoides and M. formosa, species that also have discolorous and suprabasal leaves and glomerulate inflorescences. From the first species, it can be distinguished by papyraceous leaves with the abaxial surface covered by lepidote trichomes. From the second species, it can be distinguished also by the texture of leaves, and by its narrower size, crenulate to serrulate margins and acute base, besides the smaller size of the flowers. The new species is known from the states of Espírito Santo, Rio de Janeiro and eastern São Paulo, and is in danger of extinction.

Myrcia adulterina, a new species from the Brazilian Atlantic Forest, is here described, illustrated and compared with morphologically related species. Additionally, its distribution map and a preliminary conservation status are presented. The new species is here inferred as belonging to Myrcia sect. Reticulosae due its leaves with raised venation, staminal ring densely pilose, hypanthium prolonged in a tube with glabrous inner walls and 3-locular ovaries. Within this section, the species is morphologically related to Myrcia pubipetala, from which it can be distinguished through the laxly reticulate leaf venation and thyrsoid inflorescences with all axes strongly flattened and striated when dry. Myrcia adulterina was misidentified during at least 15 years in herbaria under the name Marlierea tomentosa (currently synonym of Myrcia strigipes, a species belonging to Myrcia sect. Aulomyrcia), which is also morphologically similar. A brief discussion clarifying the morphological differences between these species is also presented.

A new species of Cosmetidae belonging to the genus Metavononoides Roewer, 1928 is herein described. Metavononoides melanacanthus sp. nov. is clearly recognized by its distinctive tarsal formula, its long legs (reaching over 60 mm), and by its characteristic color pattern. The new species is the twelfth species included in the genus. It is known only from two localities: the type locality, Barra de São João, Casimiro de Abreu and from Aldeia Velha, Rio de Janeiro, Brazil.

Tovomita iaspidis, a new species from the Brazilian Atlantic Forest, is described, illustrated, and its morphological affinities with other species and its diagnostic characters are discussed. The new species is similar to Tovomita glazioviana, from which it can be distinguished by having greenish patent petals and larger and reddish pistillode in the staminate flowers. While T. glazioviana is found in the Atlantic Forest in the states of Bahia, Minas Gerais, and Rio de Janeiro, T. iaspidis is so far only known from two small remnant areas of montane forest in southern Bahia State, Brazil.

Begonia margaretiana is morphologically similar to Begonia paulensis, with which it is compared. The new species grow in hygrophilous Atlantic Forest in the south of Rio de Janeiro state, Brazil. Description, comparisons with a morphologically similar species, etymology, taxonomic comments, illustrations, a map, and the conservation status of the new species are provided.

Erythroxylum riparium, a new species of Erythroxylaceae from the Brazilian Atlantic Forest, is described and illustrated. The species was found in southern Bahia State growing along river banks within tropical rain forest fragments. It can be distinguished from other similar species of Erythroxylum by the combination of branchlets intensely dotted with elliptic lenticels, these often united with each other, undulate leaf margin, three bracteoles per flower, and partially connate styles. These diagnostic characters and other observations concerning the new species are presented and compared with those from similar species.

The new species Chrysophyllum pubipetalum from the Brazilian Atlantic forest of Espírito Santo state is described and illustrated. This new species is characterized by the presence of trichomes on both surfaces of the corolla (a character unique in the genus), channeled petioles, a relatively short pedicel length, and various characters of the fruits and seeds. A distribution map and a table distinguishing the new species from morphologically similar species are also included. As based on IUCN criteria, the species is considered critically endangered.
