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.

Inga (Fabaceae, mimosoid clade) is an important genus in the Atlantic Forest of Brazil where there are 44 species, 60% of which are endemic. In this work, we describe two new species of Inga (I. teresensis and I. tripa) from the Atlantic Forest and provide identification keys to the species of sections Vulpinae and Leptinga in the biome. Illustrations and comments about the geographic distribution, conservation status, phenology, etymology, and taxonomy of the new species are also included. Inga teresensis is only known from the state of Espírito Santo and is categorized as Critically Endangered (CR). Inga tripa occurs in coastal areas of the states of Bahia, Paraíba, Pernambuco, and Sergipe and is categorized as Learn Concern (LC).

A synopsis of the genus Cnidoscolus is presented for the midwestern region of Brazil, which resulted from the analysis of about 1,200 specimens from 62 national and foreign herbaria, including type collections. Observations of populations in field were also made. Nine species are recognized, one of which, C. mcvaughii, is new to science. It is described and illustrated, and comments about its geographic distribution, morphological relationships, systematic position, phenology, and conservation status are provided, as well as images and a map. The other species are contrasted by a dichotomous key. Also, distributional information, maps, conservation evaluations, images and morphologically diagnoses are included. Eight synonymizations, one lectotypification, a neotypifcation, and the re-establishment of C. neglectus are proposed.

Avicularia diversipes (C. L. Koch 1842) known previously only from its original description is redescribed along with Avicularia sooretama sp. nov. and Avicularia gamba sp. nov. The three species are endemic to Brazilian Atlantic rainforest. With other Avicularia species, they share a procurved anterior eye row, slender embolus and medially folded spermathecae, whereas they have unusual characters, such as a very long and spiraled embolus (A. diversipes) and spermathecae with multilobular apex (A. sooretama sp. nov.). Furthermore, the three species lack a tibial apophysis in males and share a distinctive color pattern ontogeny that is not known in any other Avicularia species. The conservation status of the three species is discussed, especially with respect to endemism, illegal trafficking and habitat destruction. The creation of protected areas in southern State of Bahia, Brazil, is recommended, as well as the inclusion of these species in IUCN and CITES lists. Appendices with figures and species information are presented to facilitate correct specimen identification by custom officers, in order to limit illegal traffic.

A New Species

Taxonomic studies of Mimosa subser. Polycephalae revealed a new species and indicated the need for taxonomic and nomenclatural adjustments in the group. Mimosa pseudoracemosa is described and illustrated as a new species from Goiás State in central-western Brazil. We discuss its geographic distribution, environmental preferences, phenology and conservation status and compare it with the morphologically similar M. pseudoradula and M. flavocaesia. A new status for M. pseudoradula var. detonsa and a new name are proposed (= M. detonsa), including M. pseudoradula var. anapolitana and M. pseudoradula var. crystallites as its synonyms, as well an updated circumscription for M. pseudoradula without the admission of varieties. We also present descriptions, images, maps, comments on their distributions and morphological relationships, flowering and fruiting periods, and conservation statuses. In addition to the morphological and geographic discontinuities of the aforementioned taxa, their trichome micromorphology supported the establishment of the new species, as well as the taxonomic decisions involving M. pseudoradula.

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.

Brazil includes a very high diversity of bamboos, but this diversity is far from completely known. We increase the list of Brazilian woody bamboos by describing two new species of Chusquea, which belong to subgenus Rettbergia. Chusquea ciliatifolia sp. nov. differs from other species of this subgenus by its mottled culms, distinctly ciliate margins of the foliage leaf blades and pilose synflorescences; and C. mirabilis sp. nov. by the presence of branches with sericeous girdles. Both C. ciliatifolia and C. mirabilis occur exclusively in the Atlantic Forest, from the states of Bahia and Minas Gerais, known only from five and three populations, respectively. Comments on morphology, taxonomic relationships, ecological aspects, and conservation status of these new species are provided.

Adenocalymma, with approximately 75 species, is one of the largest genera from tribe Bignonieae (Bignoniaceae). The genus mostly includes yellow-flowered lianas and shrubs that are conspicuous components of the dry and wet Neotropical forests. As part of an ongoing taxonomic and phylogenetic study of this group, we found unusual materials that do not match any of the currently recognized taxa. These materials formed the basis of two new species described here, which are endemic from the Brazilian Atlantic forest: Adenocalymma lineare, and Adenocalymma apetiolatum. Adenocalymma lineare resembles Adenocalymma nervosum on the linear leaflets, but differs in the habit, prophyll morphology, leaflet venation, floral bracts, bracteole morphology and dimensions, corolla color and morphology, anther and stigma position. While Adenocalymma apetiolatum closely resembles Adenocalymma sessile and Adenocalymma subsessilifolium on the sessile leaf insertion and shrubby habit, it differs from both species by the corolla color, indument type and color. Apart from that, Adenocalymma apetiolatum differs from the former by the prophyll morphology, floral bract and bracteole morphology, and the latter by the corolla morphology. These two new taxa are illustrated, and distribution maps are provided here. Notes on the taxonomy, geographic distribution, habitat, and conservation status are also included.

Two new species of Cryptanthus from Bahia State, in northeastern Brazil, are described and illustrated. Cryptanthus apiculatantherus occurs in Atlantic Forest and Cryptanthus brevibracteatus was discovered in a transition area between Atlantic Forest and Caatinga. Cryptanthus apiculatantherus and C. bibarrensis have similar stem lengths and leaf blade shapes, but differ mainly by the stem diameter, width of the leaf sheaths, sepal and petal color, anther apex shape, and length and width of the ovary. Cryptanthus brevibracteatus and C. warren-loosei have a similar leaf blade color and are geographically close to each other, but differ by the number of flowers in the apical cluster of flowers of the inflorescence, length and width of the floral bracts, length of the sepals, connation of the sepals and length of the sepal lobes. Data about the geographic distribution, habitat, phenology, conservation status, taxonomic comments, a distribution map and photographs of the new species are provided. In addition, there are tables included that compare the new species to morphologically similar species.
