The genus Abarema (Caesalpinioideae, Mimosoid clade), as traditionally circumscribed, emerged as polyphyletic in recent phylogenetic studies. The type species of the genus, Abarema cochliacarpos, is positioned within the Inga clade, separate from the remaining species previously included in the genus (now combined to Punjuba and Jupunba genera). Here we present the new circumscription of Abarema. The two species included in the genus occur in the Atlantic Forest and Caatinga biomes in Brazil. We provide a morphological description of Abarema and its two species, an identification key, conservation status and a geographic distribution map.

A synopsis of the species of the genus Abarema (Leguminosae) growing in Colombia is presented. Sixteen species are recognized, including five varieties, three endemic species (A. callejasii Barneby & Grimes, A. josephi Barneby & Grimes and A. lehmannii (Britton & Rose ex Britton & Killip) Barneby & Grimes) for the country and two new records for the Colombian flora (A. acreana (J.F. Macbr.) L. Rico and A. racemiflora (Donn. Sm.) Barneby & Grimes). Two dichotomous keys are provided for the identification of the species: One for specimens with the presence of flower and/or fruit, and another that uses strictly vegetative characters. A brief discussion is included for each taxon highlighting its diagnostic morphological characters, notes on their geographical and altitudinal distribution, flowering and fruiting times, common names and uses, as well as a list of the herbarium specimens studied. In Colombia, the species of Abarema are predominantly found in humid and rain forests, mainly in the Andean and Amazonian regions.

Resumo Ingeae é uma importante tribo da família Leguminosae com cerca de 950 espécies em 36 gêneros, dos quais 24 são endêmicos do Novo Mundo. Este trabalho apresenta o estudo florístico de 16 espécies de Ingeae, reunidas em sete gêneros: Abarema (seis spp.), Albizia (duas spp.), Calliandra (duas spp.), Chloroleucon (duas spp.), Enterolobium (duas spp.), Leucochloron (uma sp.) e Zygia (uma sp.) ocorrentes no Espírito Santo. O gênero Inga, devido ao grande número de espécies, será publicado posteriormente. Dentre as espécies estudadas, 14 (88%) são endêmicas do Brasil, sendo uma, Abarema barnebyana, restrita ao Espírito Santo e sete (44%) restritas ao bioma Floresta Atlântica. No estado, 14 espécies ocorrem em Floresta Ombrófila Densa. Na Restinga, são encontradas oito espécies e na Floresta Estacional Semidecidual, sete espécies. São apresentadas chaves para identificação, descrições, ilustrações, comentários taxonômicos, períodos de floração e frutificação, distribuição geográfica e habitats preferenciais.
Among the mimosoid legumes (Fabaceae, Caesalpinioideae, mimosoid clade), many genera have complex nomenclatural histories, including Abarema that stands out due to numerous nomenclatural changes. Abarema is a Neotropical genus that currently comprises c. 50 species, with centres of diversity in the Amazon and Atlantic rain forests. Recent phylogenetic studies of Abarema have demonstrated the non-monophyly of the genus, which was shown to be polyphyletic with species traditionally recognized under the genus placed in three main clades that are intermingled with other genera of the former tribe Ingeae. The type species of Abarema groups with Inga, Macrosamanea, Enterolobiump.p., Zygia and Blanchetiodendron, whereas the other two clades correspond to the former genera Jupunba and Punjuba. The aim of this study is to build a phylogenetic tree of Abarema s.l. supporting the reinstatement of Jupunba and Punjuba, based on morphological and phylogenetic evidence, and to carry out a nomenclatural overhaul of the species and implement necessary typifications. For Punjuba we reinstate three species and add three new combinations. Jupunba comprises 37 species, of which eight are reinstated; in addition, the resurrection of one species with a new synonym is proposed and 29 new combinations are made. In total, 63 taxa are revised, including accepted names, synonyms and excluded names. A taxonomic key is presented for the identification of Punjuba, Jupunba and related genera. We present 40 new combinations, one new taxonomic status and 18 corrections of nomenclature category for lectotypes and two neotypes. One lectotype is designated, one species is reinstated with a new synonym and a second step neotypification is made. We located 97 unreported types during the revision, which are cited here for the first time.
Abarema villosa Iganci & M. P. Morim (Fabales: Fabaceae) is a medicinal and ornamental plant in the Cerrado biome of Brazil. Poekilloptera phalaenoides L. (Hemiptera: Flatidae) is a polyphagous pest that imbibes plant sap. This insect was observed on A. villosa plants in Diamantina, Minas Gerais State, Brazil. Poekilloptera phalaenoides uses P. phalaenoides plants as a site for shelter, feeding, and reproduction. This is the first report of A. villosa as a host of P. phalaenoides.

Premise of research. Here we present the first molecular phylogeny of the Abarema alliance, based on a large species sampling from across its geographical range. Our aim was to test the monophyly of the alliance and to analyze the major biogeographical patterns throughout the Neotropics. Methodology. DNA sequence data were derived from the chloroplast matK region and nuclear external transcribed spacers (ETSs) and were phylogenetically analyzed in order to resolve systematic relationships. Pivotal results. Our results agree in part with Barneby and Grimes's circumscription of the alliance, including the genera Hydrochorea and Balizia and part of Abarema. However, Abarema, the largest genus within the alliance, is polyphyletic. The type species of Abarema, Abarema cochliacarpos, is closer to genera of the Inga alliance. There is also an Andean clade distinct from the remaining species of Abarema sensu lato, Hydrochorea, and Balizia. Conclusions. Two groups of Abarema sensu lato (one restricted to the Andes), but excluding the type species A. cochliacarpos, are here proposed, together with the genera Hydrochorea and Balizia, as a new alliance. The results demonstrate that monophyletic groups have to be recircumscribed and some described as new taxa. We also present preliminary observations about the biogeography of the group in different Neotropical forest formations. The Andean clade appears as sister to all other taxa within the new alliance when combined ETS and matK data are analyzed. Multiple independent events must have occurred during the colonization of the West Indies and Central America. Species in the Atlantic forest and Amazonia are the result of the most recent radiation events within the group.
The Baturité mountain range is one of the largest remnants of Atlantic forest located in the the Brazilian semi-arid region. The area presents a high diversity, being considered of extreme biological importance for the conservation. The species of family Leguminosae were collected from February/2007 to February/2009 and the species list was complemented with herbarium analysis. The Leguminosae was represented by 56 genera and 132 taxa. The subfamily Papilionoideae contributed with higher richness of genus and species (31 genera and 58 taxa) followed by Mimosoideae (17 genera and 41 taxa) and Caesalpinioideae (eight genera and 33 taxa). Among the species studied in the area, 55% of them are trees and shrubs. The most diverse genera are Mimosa L. (15), Senna Mill. (12), Desmodium Desv. (seven) e Chamaecrista Moench, Bauhinia L., Inga Mill. and Aeschynomene L. (six each).
The genus Abarema belongs to the tribe Ingeae (Fabaceae, Mimosoideae) and comprises about 50 neotropical species. The genus has a high diversity of species in Amazonia (c. 35 species), and the Atlantic Domain is the second richest biome. This article presents a taxonomic treatment for the Atlantic species (eastern Brazil) of Abarema. Nine species occur in ombrophilous dense forest, coastal scrub and campos rupestres (‘rocky fields’). Endemic species are centred in southeast and northeast Brazil, agreeing with the general patterns described for the Atlantic forest hotspot. Some species represent links between the Atlantic flora and other Brazilian biomes, such as the Amazon and cerrado. Descriptions, illustrations and a key for identification are presented, and a new synonym is proposed. © 2012 The Linnean Society of London, Botanical Journal of the Linnean Society, 2012, 168, 473–486.
