Besleria is a Neotropical genus of terrestrial herbs, shrubs and small trees growing in the understory of rainforests, with more than 160 recognized species, and is one of the larger and more diverse genera of Gesneriaceae. It belongs to the monophyletic tribe Beslerieae, and recent phylogenetic studies indicate that the genus is monophyletic. During field expeditions in the Brazilian Atlantic Rainforest, we collected specimens that could not be identified as any described species. After morphological analysis and comparison with related species, we assigned these specimens to three new species of Besleria. In this paper, we describe and illustrate Besleria aurea, B. brevicalyx and B. diabolica and provide data on their ecology, distribution and conservation status.

Three new Brazilian species of Aulonemia, a Neotropical woody bamboo genus, are described and illustrated: Aulonemia cincta, with its distinctive corky girdles; Aulonemia prolifera, characterized, among other Brazilian congeners, by its fimbriate leaf sheaths; and Aulonemia soderstromii, with its conspicuous cluster of spreading fimbriae. These new species all propagate by amphipodial rhizomes, an unusual feature shared with the Brazilian species A. aristulata, with which they are morphologically compared. Comments about habitat, distribution, phenology, and conservation status for each species are provided, as well as photographs taken in the wild.

Two new species, Phyllanthus itamarajuensis and P. tuberculatus (Phyllanthaceae), currently restricted to the Atlantic Forest of Bahia State, Brazil, are described and illustrated. Phyllanthus itamarajuensis is distinguished by having long styles (2–2.2 mm long) associated with subshrubby habit, discretely asymmetrical basal leaves, and anthers with vertical dehiscence. Phyllanthus tuberculatus is characterized by glabrous leaves, a long pistillate pedicel (18–20 mm long), flowers of both sexes 5-merous, disk of the staminate flowers with five obtriangular segments with tuberculated surfaces, each being separated by a deep recess, and each with a central pore, anthers with non-divergent thecae, and a patelliform pistillate disk. The systematic position of both new species is discussed, and comments are provided on their morphological relationships, geographic distribution, conservation status, environmental preferences, and phenology.

Eight Brazilian Atlantic Rainforest species are described and illustrated: Calyptranthes santalucia, Eugenia barrana, E. culicina, E. lacistema, E. viscacea, Myrcia basicordata, M. monoclada and Myrciaria evanida. Calyptranthes santalucia, from the state of Espírito Santo, is related to C. brasiliensis, differing for its acute leaves and pauciflorous inflorescences; Eugenia barrana, from the states of Minas Gerais and Bahia, is related to E. chlorophylla, but has smaller leaves and larger flowers; Eugenia culicina, from the state of Pernambuco, is related to E. roseiflora, differing through the smaller petioles, adaxially sulcate lateral veins, pilose flowers and larger fruits; Eugenia lacistema, from Bahia, is related to E. platyphylla, differing by the inflorescences with lignified bracts and smaller pedicels;  Eugenia viscacea, from Bahia, is related to E. ellipsoidea, differing through the inflorescences with densely imbricate bracts and smaller pedicels; Myrcia basicordata, from Espírito Santo, is related to M. pubescens, but presents applanate glabrous twigs and glabrous and sessile leaves with cordate base; Myrcia monoclada, from Bahia, is related to M. riodocensis, but has larger leaves and pentamerous flowers, and Myrciaria evanida, from Espírito Santo and Minas Gerais, resembles M. floribunda, differing by the vanishing secondary veins and smaller flowers. The new species are also evaluated as to their conservation status according to IUCN criteria. Additionally, the synonymization of Eugenia apiocarpa under E. astringens and of Eugenia pleurantha under E. umbellata and the lectotypification of Eugenia ellipsoidea are proposed.

Three new species of Pleroma are described: Pleroma costatocalyx, P. kollmanniana and P. subsessilis. All three species are morphologically similar to Tibouchina heteromalla and related species, especially due to the shrubby habit, elongated inflorescences, flowers with purple petals, but white at their bases, antesepalous stamens with the connective covered with glandular trichomes, and by the short (ca. 4–5 mm long), curved style. All three species differ from T. heteromalla by the styles with trichomes (vs. glabrous in T. heteromalla). Pleroma costatocalyx also differs from T. heteromalla by the longitudinally costate hypanthium, P. kollmanniana by the strongly winged branches, bigger leaves, and shorter petioles, and P. subsessilis by the concolorous leaves and antepetalous stamens with glabrous connective and appendages. All new species grow in vegetation associated with inselbergs and are endemic to Espírito Santo state, despite the fact that one of them (P. costatocalyx) was collected very close to the border with Minas Gerais, where it probably occurs. We present descriptions, taxonomic comments, illustrations, and conservation status assignments for the new species.

Species of Sisyrinchium from Southern Brazil represent 31% and 86% of the genus diversity throughout the Americas and the Brazilian territory, respectively. However, new species are still being discovered and three are presented here: S. pampeanum, from the Pampa Biome and S. diversicarpum and S. sectiandrum, from the Atlantic Forest Biome. The taxa are described, illustrated and taxonomic comments, conservation status and comparisons with related species are provided.

Eleven Species

Neocalyptrocalyx (Capparaceae) is a Neotropical genus that comprises eleven species that occur in the lowlands of Brazil, Guyana, French Guyana, Suriname, Venezuela, and Ecuador. The study of collections deposited in herbaria added to field observations allowed the recognition of three species as new to science, and those are formally presented here: Neocalyptrocalyx aequatoriensis, known only from eastern Ecuador, Neocalyptrocalyx atlanticum from the Atlantic Forest, and Neocalyptrocalyx polycataphyllus from the Brazilian Amazonia. Neocalyptrocalyx aequatoriensis represents the new westernmost boundary for the genus and the first generic record for Ecuador. We present diagnoses, descriptions, ink illustrations, field photos, distribution maps, notes on ecology, habitat, morphology, phenology, conservation status, and a key to distinguish the new species from related species.
