Abstract—Solanum confertiflorum (Solanaceae), a new species for the Cyphomandra clade, is described and illustrated. The species is endemic to Bahia state, in Brazil, restricted to few localities, inhabiting seasonal forests and outcrops in the Caatinga biome. It is morphologically related to S. luridifuscescens, sharing the papillose anthers without swollen connectives, but distinguished by the forked cymes with flowers congested at the apex, swollen calyx with shorter lobes, as well as shorter, sessile stamens. The morphology, geographic distribution, ecology, and conservation status are discussed and a key for the Brazilian species without swollen connectives belonging to the Cyphomandra clade is presented.

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.

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.

Abstract— A new species of Phyllanthus with phylloclades endemic to the State of Bahia is described here. Phyllanthus dracaenoides can be recognized for its peculiar habit that resembles a species of Dracaena, a very unusual height of up to 7 m, the plagiotropic phylloclades spirally arranged, and its vermiform cincinni. Notes on its habitat, taxonomic affinity, conservation status, geographic distribution, illustrations, and photographs are provided.

Even though a huge area of the country remains untouched, two tribes, eight genera and ninetyeight species of Passalidae are found in Brazil until now. Specialists described many taxa and gave both immature and adult taxonomic characteristics, showing bionomic aspects, which are shown in this paper. A checklist of Brazilian species is presented in this study with geographic distribution data. Veturius criniferous sp. nov. from Rond nia, Brazil is described and illustrated.

A revisional taxonomic study of Adesmia subg. Adesmia ser. Bicolores has unveiled a new species from southern Brazil. Adesmia miottoae is described and illustrated here. Its geographic distribution, phenology, conservation status and morphological similarities with its closest relatives, Adesmia punctata and A. incana, are presented. The species is distinguished by glandular trichomes covering all the aerial parts of the plant, except the corolla. These trichomes are shorter than those of Adesmia punctata. Additionally, a detailed anatomical description of the leaflet blade is provided.

A new species of Matelea from central and southern México with green to black corollas and pubescent lobes is described here: Matelea ojadapantha. This taxon is morphologically similar to M. schaffneri and M. atrostellata but differs by the corolla and corona morphology and has a disjunct geographic distribution. Descriptions, illustrations, morphological comparisons, map of the distributions of this species as well as their conservation status is provided. This discovery highlights México as a center of diversity of the genus, as more than 70 species are currently known in the country. Furthermore, 60% of those species are endemic.

Zanthoxylum unifoliolatum Groppo & Pirani (Rutaceae), a new species from northeastern Brazil is here described and illustrated. To date, this species is known from a small number of collections from the state of Sergipe and considered endangered, given its restricted geographical distribution and the rapid deforestation of the Brazilian Atlantic Rainforest. Z. unifoliolatum can be readily distinguished from other Brazilian Zanthoxylum by its unifoliolate leaves, rather than pinnate leaves present in other Brazilian species of the genus A detailed description and illustrations of this new species are provided, as well as comments on the geographic distribution, phenology, generic relationships and conservation status. Additionally, a key to the species of Zanthoxylum from Northeastern Region of Brazil is provided.

Chionanthus is a genus from the plant family Oleaceae that is characterized by the presence of small calyces, 4-lobed corollas with petals arranged in pairs and held together by the filament bases, less commonly with a very short tube, two stamens in most species, and drupaceous fruits. As part of ongoing taxonomic studies of the Neotropical Oleaceae, we detected an undescribed species from Peru, that is here described and illustrated. Chionanthus chrysopetalus Cornejo ex Lombardi resembles C. implicatus and C. compactus, two species from northwestern South America, by the elliptic leaves. However, C. chrysopetalus can be separated by both taxa by the hispidulous indument, and yellow corollas, unusual features within the genus. In this study, I present a detailed description for the new taxon, notes on the phenology, geographic distribution, habitat, conservation status, and etymology.

Abstract—Merostachys delicatula, a new species recorded thus far only from the montane Atlantic forest of southern Bahia, is described and illustrated here. Comments on its taxonomy, distribution, habitat, and phenology are presented. Among the narrow-leaved congeners occurring in Bahia, the new species is most similar to M. leptophylla. It is distinguished by having internodes glabrous to scabrous (vs. glabrous in M. leptophylla); internodes with an infranodal band of trichomes (vs. absent); culm leaf sheaths abaxially scabrous (vs. glabrous); upper glumes 1.2‐2.1 mm wide (vs. 3.5‐4 mm); anthecia dull (vs. shiny); lemmas 1.5‐2.7 mm wide, abaxially pubescent (vs. ca. 4 mm, glabrous); and paleas 1.2‐2.3 mm wide (vs. ca. 4 mm). We also provide an assessment of the conservation status of the new species and a geographic distribution map for both species.

A new species of Gonolobus from northwestern Mexico with green and barbate corollas is described here. Gonolobus naturalistae is morphologically similar to G. barbatus, G. pectinatus, and G. sororius but differs in corolla and corona morphology and distribution. Descriptions, illustrations, morphological comparisons, and geographic distribution maps of these species, as well as their conservation status, are provided. This discovery highlights Mexico as a center of diversity for the genus, with around 40 species recorded, and highlights its endemism, with 48.7% of the species occurring in the country.
