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.

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.

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.

The Brazilian species of Bittacus Latreille (Mecoptera: Bittacidae) are reviewed and one new synonym is proposed (Thyridates willmanni Collucci & Amorin syn. n. of Bittacus diversinervis Souza Lopes & Mangabeira). Three new species are herein described: Bittacus cruzi sp. n. from Amazonas, Presidente Figueiredo and Manaus, B. ferreirai sp. n. from Bahia, Aracatu and B. varzeanus sp. n. from Amazonas, Tefé, bringing the current number of Bittacus species in Brazil to 18. Illustrations, comments, and distribution maps of each species are presented. An identification key to the Brazilian genera of Mecoptera and Bittacus species is also presented.

Background and aims – As “islands in the sky” of northern South America, the isolated ecosystems of the Pantepui province include a distinct flora with high levels of endemism and which are ancestral areas for many angiosperm lineages. About one fifth of Pantepui angiosperm species are distributed in Poales, a highly diverse angiosperm order.Methods – Recent field trips were carried out on two Brazilian tepuis, by foot and helicopter. Herbarium collections were consulted and compared with the proposed new species. Key results – Four new species of Poales, three Navia Schult. & Schult.f. (Bromeliaceae) and one Paepalanthus Mart. (Eriocaulaceae) were found. Descriptions, illustrations, and distribution maps of the new species, as well as an identification key to Brazilian Navia species, are provided.

Sectional Classification

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.

External Morphology

The genus Gastrodynerus is here revised based on external morphology and male genitalia. Bohart (1984) proposed Gastrodynerus as a new genus with three species: G. vanduzeei (Bohart 1948), G. searsi Bohart, 1984, and G. stangei Bohart, 1984. Later, Rodriguez-Palafox (1996) added G. tacubayae (de Saussure, 1857). Herein, we describe four new species from Central America and South America: G. guatemalensis sp. nov.; G. barretti sp. nov.; G. aimara sp. nov. and G. yungaensis sp. nov. After this taxonomic revision, the Gastrodynerus includes eight species widely distributed in the New World. An identification key is provided for all of the species.

Among the more than 170 species of Euphorbia (Euphorbiaceae, Malpighiales) that occur in Madagascar, some remain poorly known and dramatically under-collected, and are based on vague and incomplete descriptions. As part of an ongoing study of the genus in Madagascar, a revision is presented of E. section Pachysanthae, which comprises six species endemic to this island that show clear morphological affinities to one another. Expanded descriptions are provided for the four species already named, and the two others are described as new (Euphorbia haevermansii and Euphorbia nusbaumeri), both from the Daraina region in north-eastern Madagascar. An identification key is provided to the species, which are characterized by having developed leaves, unarmed twigs (unlike most of Malagasy Euphorbia), leafy deciduous cyathophylls, and ecarunculate seeds. Members of the section differ from one another in their geographical distribution, habit, and the shape and the size of their leaves, glands, cyathia and cyathophylls, as well as the size, surface and number of locules of the fruits. The morphological affinities of these six species are discussed and preliminary conservation assessments are provided.
