Discolobium, an exclusively South American legume genus, includes six species. The nomenclature of each taxon has been reviewed, and six synonyms are presented. Discolobium hirtum, D. junceum, D. leptophyllum, D. psoraleaefolium, D. pulchellum and D. tocantinum can be differentiated mainly by the number and shape of leaflets, degree of fusion of calyx lacinia, morphology of calyx lacinia, petal and fruit wings, and ornamentation of the seed chamber. Species of this genus occur in Pantanal, Chaco, and Caatinga vegetation associated with marshes and river banks and in tropical ombrophilous alluvial forests, either dry or flooded most of the year. An identification key to the species is presented, together with a detailed taxonomic revision of the genus and its species, distribution maps, linedrawings, and comments on the taxonomy and ecology of each species. Lectotypes for D. elongatum, D. hirtum, D. junceum, D. leptophyllum, D. leptophyllum var. junceum, D. leptophyllum var. junceum f. grandiflora, D. leptophyllum var. junceum f. parviflora, D. paucijugum, D. psoraleaefolium, D. pulchellum, D. pulchellum var. major, D. pulchellum var. viscosissimum and D. tocantinum are herein designated.

A New Species

A taxonomic revision of the South American genus Amburana comprised of three species is presented, including the new species A. erythrosperma which is described and illustrated. Amburana cearensis occurs widely in Argentina, Bolivia, Brazil and Paraguay.  Amburana acreana occurs in the Bolivian, Brazilian and Peruvian Amazon. Amburana erythrosperma is endemic to the southern Chapada Diamantina, Bahia, Brazil. The species are distinguished by the color of the stem, the number per leaf and shape of leaflets, the size of inflorescence, color and size of the standard petal, fruit with endocarp developed to form a papery wing surrounding the seed or this lacking, and color of seed. A key to the species is provided together with descriptions, taxonomic comments, geographical distribution maps and illustrations for each.  Lectotypes for A. acreana and A. cearensis are designated.

I present the first taxonomic revision for T.subg.Austrotradescantia, based on extensive field, cultivation and herbaria studies. I accept 13 species, three of them (i.e. T.atlantica, T.hertweckii and T.tucumanensis) being described as new in the present study. I provide an identification key to the species, distribution maps, descriptions, comments, conservation assessments and illustrations for all species. The troublesome weed T.fluminensis has its specific limits clarified and its native range is presented so it can serve as a basis to better understanding its ecological requirements and to help control it throughout its invasive range. Furthermore, I highlight that T.mundula, a commonly neglected species closely related to T.fluminensis, might also represent a troublesome weed. Tradescantiamundula has been widely introduced in cultivation under the name T.albiflora and seems to have also escaped from cultivation. However, due to the hitherto poorly understood specific limits of T.fluminensis, T.mundula has been treated as a mere cultivar of T.fluminensiss.s.

Respective Species

The South American genus Panca Evans, 1955 and its respective species are revised. Previous to this study, the genus included solely its type species, Lerodea subpunctuli Hayward, 1934, until Panca moseri Dolibaina, Carneiro & O. Mielke, 2017 was described recently. However, as a result of a broader morphological study including closely related genera, we here propose that Panca assembles 12 species, most of which inhabit open environments such as the Cerrado biome and the natural grasslands of the Atlantic Forest biome. Eight species formerly included among other genera of Moncina are here combined with Panca: Panca satyr (Evans, 1955) comb. nov., Panca tobiasi (Mielke, 1992) comb. nov., Panca trogon (Evans, 1955) comb. nov., Panca steinhauseri (Dolibaina & A. Warren, 2015) comb. nov., Panca acroleuca (Plötz, 1884) comb. nov., and Panca mirnae (O. Mielke, Dolibaina, Carneiro & A. Warren, 2015) comb. nov. (all formerly in Artines Godman, 1901), Panca paulo (Bell, 1932) comb. nov. (formerly in Eutocus Godman, 1901), and Panca mictra (Evans, 1955) comb. nov. (formerly in Vidius Evans, 1955). Additionally, two new species are described from Brazil: Panca puri Medeiros, O. Mielke & Casagrande sp. nov. (from Pará, Pernambuco, Minas Gerais, Rio de Janeiro and Paraná) and Panca xavante Medeiros, O. Mielke & Dolibaina sp. nov. (from Mato Grosso, Goiás, Distrito Federal and Minas Gerais). A neotype for Apaustus acroleuca Plötz, 1884 is designated. Illustrations of the male and female genitalia and distribution maps are presented for all the species of Panca and an identification key is provided for both sexes.

AbstractThe genus Endeius Coiffait & Sáiz, 1968 (Staphylininae: Staphylinini), distributed from Chile and Argentina through Juan Fernández Is. and Galapagos Is., is revised using characters of external morphology and male and female genitalia. Endeius comprises seven valid species: E. punctipennis (Solier), E. nitidipennis (Solier), E. subpunctipennis Coiffait & Sáiz, E. loensis Coiffait & Sáiz, E. franzi Sáiz, E. lugubris Sáiz and E. ovaliceps Coiffait. Belonuchus multipunctatus (Coiffait), comb. nov., is excluded from Endeius. An identification key to all species of the genus is provided. Monophyly of Endeius, as considered in the present study, is supported by one synapomorphy from the external morphology. Within the genus, the best supported subgroup consists of E. punctipennis (Solier), E. subpunctipennis Coiffait & Sáiz, E. loensis Coiffait & Sáiz and E. ovaliceps Coiffait.

ABSTRACT The taxonomic revision of Amorimia (Malpighiaceae) is presented, including typifications, and descriptions for all accepted species. The genus is endemic to Seasonally Dry Tropical Forests and Rainforests of South America, and its species can be distinguished by morphological details of leaves, indumenta, inflorescences, flowers, and fruits. This study includes an identification key for the subgenera and species of Amorimia, illustrations, distribution maps, conservation risk assessments, and comments on ecology, nomenclature, and taxonomy for all species. Additionally, I provide a key to differentiate Amorimia from the remaining genera of the Malpighioid clade.

In the present study, we presented a taxonomic revision of the genus Sorbaria (Sorbarieae; Amygdaloideae) with a new infrageneric classification. Moreover, we extensively reviewed various data for Sorbaria species, including previous anatomical, micromorphological, and palynological data. The new sectional classification was based on morphological, micromorphological, and palynological evidence, with two sections: sect. Sorbaria aut. and sect. Kirilowiana J.-H. Song & S.-P. Hong (sect. nov.). Overall, four species and five varieties (including two nomenclatural novelties) were recognized: S. sorbifolia (Linnaeus) A. Braun var. sorbifolia, S. sorbifolia var. glandulifolia J.-H. Song & S.-P. Hong, S. sorbifolia var. stellipila Maximowicz, S. pallasii (G. Don) Pojarkova, S. tomentosa (Lindley) Rehder var. tomentosa, S. tomentosa var. angustifolia (Wenzig) Rahn., S. kirilowii (Regel & Tiling) Maximowicz var. kirilowii, S. kirilowii var. arborea (C.K. Schneider) J.-H. Song & S.-P. Hong (comb. & stat. nov.), and S. kirilowii var. dubia (C.K. Schneider) J.-H. Song & S.-P. Hong (comb. nov.). Some illustrations and syntype were designated as the lectotype for several names. The classification was based on a comprehensive morphological examination of herbarium specimens, including field observations and observations of types, micromorphological, and palynological characteristics. In addition, we provided an identification key, diagnostic characteristics, full descriptions, comprehensive nomenclatural treatments and taxonomic notes (including complete synonymy), and distribution maps of Sorbaria species.

The genus Pelargonium (Geraniaceae) includes ca. 281 species, organised into 16 sections and four subgenera. Since the last revision of the genus by Knuth in 1912, recent revisions have been completed for all of the currently recognised sections of the genus with the exception of three, sections Ciconium, Otidia and Peristera. Pelargonium sect. Peristera is lectotypified, and a taxonomic revision of the southern African species of this section is presented, recognising 11 species, of which one, P. sessiliflorum, is described as new. An identification key is provided along with nomenclature, descriptions, distribution maps, habitat information, and conservation notes for the 11 recognised species, synonymising nine names.
