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.

A New Species

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.

Single Locality

Paepalanthus mellosilvae is here described and illustrated as a new species of Eriocaulaceae from the Atlantic Forest domain in Minas Gerais state, Brazil. The new species is known from a single locality in the Mantiqueira Range, growing along trails through cloud forests. According to the IUCN criteria, it is suggested here as critically endangered. Paepalanthus mellosilvae is compared to P. harmsii, a morphologically similar species also growing in the Mantiqueira Range, being mainly distinguished by the presence of a rhizome, narrower leaves, more numerous scapes, narrower capitula, sparsely pilose involucral bracts, and obdeltate floral bracts. Additional comments on the taxonomy, morphology, and distribution of the species, along with illustrations are provided. The specific epithet is a tribute to Prof. Dr. Renato de Mello-Silva.

A New Species

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

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.

Tocoyena atlantica, a new species endemic to southern Bahia and northern Espírito Santo states, Brazil, is here described and illustrated. The species consists of trees 5−8 m tall; with petioles 2−5 cm long, and leaf blades 7.4−24.5 × 2.5−9.1 cm, elliptic, adaxially glabrous; calyces cup-shaped with triangular lobes; corolla yellow during anthesis, with tube gradually wider towards the mouth; and laterally compressed hypanthia. Based on IUCN criteria, we consider T. atlantica endangered, with three collection localities within the Atlantic Forest domain. An identification key for species of Tocoyena occurring in the Brazilian Atlantic Forest is also provided.

A New Species

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.

Abstract—Monteiroa rubra is described as a remarkable new species from Rio Grande do Sul, Brazil. It is notably distinct from the other ten species of Monteiroa. The new species is morphologically most similar to the four species of the genus with unlobed leaves that also lack cordate leaf bases. Monteiroa rubra apparently is an endemic species known from three localities in wetlands associated with grasslands in Augusto Pestana and Fontoura Xavier municipalities in southern Brazil. A morphological description, distribution map, photographs, ecological notes, and a key to morphologically most similar species are presented. According to IUCN criteria, if a formal assessment were performed, the new species would probably be considered Endangered.
