Abstract. Recent studies have shown that the genus Acacia Mill. s.l. is polyphyletic, consisting of at least seven distinct groups of species. One of these groups, the proposed genus Parasenegalia Seigler & Ebinger, consists of seven species. We describe a new species, Parasenegalia lundellii Seigler & Ebinger, and make the following new combinations: Parasenegalia muricata (L.) Seigler & Ebinger, Parasenegalia rurrenabaqueana (Rusby) Seigler & Ebinger, Parasenegalia santosii (G. P. Lewis…

The tribes Acacieae and Ingeae (Leguminosae: Caesalpinioideae) in the Environmental Protection Area Serra Branca, Raso da Catarina, Jeremoabo, Bahia, Brazil

Abstract: Leguminosae includes six subfamilies, where the traditionally recognised subfamily Mimosoideae was accepted as a distinct clade included within the recircumscribed subfamily…

Synoptic Overview of Exotic Acacia, Senegalia and Vachellia (Caesalpinioideae, Mimosoid Clade, Fabaceae) in Egypt

The present study revealed the presence of 22 newly recorded taxa in Egypt, a contribution towards clarifying the nomenclatural status of all recorded species of Acacia and its segregate genera.

Revision of Senegalia in China, and notes on introduced species of Acacia, Acaciella, Senegalia and Vachellia (Leguminosae: Mimosoideae)

Dilemmas in generic delimitation of Senegalia and allies (Caesalpinioideae, mimosoid clade): how to reconcile phylogenomic evidence with morphology and taxonomy?

New phylogenomic evidence from 997 single-copy nuclear gene sequences for a small, but representative set of species shows that Senegalia is non-monophyletic, but instead, forms a grade that is paraphyletic with respect to the remainder of the ingoid clade.

Annotated checklist ofSenegaliaandVachellia(Fabaceae: Mimosoideae) for the Indian subcontinent

An annotated checklist of Senegalia Raf. and Vachellia Wight & Arn. taxa for the Indian subcontinent is presented, following the fragmentation and retypification of the former broadly defined genus…

Phylogenetic Relationships in Senegalia (Leguminosae-Mimosoideae) Emphasizing the South American Lineages

The first comprehensively sampled phylogeny of American and African Senegalia is presented, however Asian species are not sampled, suggesting a more complicated evolutionary history of the genus than previously considered, including probable transatlantic dispersal events.

Reinstatement and recircumscription of Jupunba and Punjuba (Fabaceae) based on phylogenetic evidence

A phylogenetic tree is built of Abarema s.l.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.

Extrafloral nectaries in Leguminosae: phylogenetic distribution, morphological diversity and evolution

This first comprehensively curated list of legume genera with EFNs is presented, detailing and illustrating their systematic and phylogenetic distributions, locations on the plant, morphology and anatomy, on the basis of a unified classification of EFN categories and a time-calibrated phylogeny.

VACHELLIA Y PARASENEGALIA (LEGUMINOSAE, MIMOSOIDEAE) DE LOS VALLES CALCHAQUÍES DE SALTA, ARGENTINA

Descriptions of Vachellia aroma, V. caven, and Parasenegalia visco are presented, along with a key for the species, comments about uses, and a list of representative specimens.

Phylogenomic analysis of 997 nuclear genes reveals the need for extensive generic re-delimitation in Caesalpinioideae (Leguminosae)

The monophyly of genera across Caesalpinioideae is tested via phylogenomic analysis of 997 nuclear genes sequenced via targeted enrichment (Hybseq) for 420 species and 147 of the 152 genera currently recognised in the subfamily and it is shown that 22 genera are non-monophyletic or nested in other genera and that non-Monophyly is concentrated in the mimosoid clade.

Mariosousa, a New Segregate Genus from Acacia s.l. (Fabaceae, Mimosoideae) from Central and North America

A series of morphological characteristics, as well as recent molecular data, separate this new genus, which has been commonly referred to as the Acacia coulteri group, which is morphologically distinct from other species of Acacia subg.

NEW COMBINATIONS IN THE GENUS SENEGALIA (FABACEAE: MIMOSOIDEAE)

Morphological and genetic differences separating the subgenera of Acacia s.l. is polyphyletic necessitate transfer of the following taxa from Acacia subgenus Aculeiferum Vassal toSenegalia, resulting in 10 new combinations in the genus Senegalia: S. grandisiliqua (Benth.), S. stenocarpa Seigler & Ebinger, nom.

Phylogenetic position and revised classification of Acacia s.l. (Fabaceae: Mimosoideae) in Africa, including new combinations in Vachellia and Senegalia

A molecular phylogenetic study of Acacia s.l and close relatives occurring in Africa was conducted using sequence data from matK/trnK, trnL-trnF and psbA-trNH with the aim of determining the placement of the African species in the new generic system.

Phylogenetic position of Madagascan species of Acacia s.l. and new combinations in Senegalia and Vachellia (Fabaceae, Mimosoideae, Acacieae)

The results indicate that the Madagascan species are placed either in Senegalia or Vachellia and conform to the morphological characters used to distinguish these genera, despite some taxa having unusual red flowers.

Overview of the generic status of Acacia (Leguminosae: Mimosoideae)

The new data clearly show that the genus Acacia, as presently defined, is not monophyletic and it is recommended that these each be recognised as a distinct genus.

A taxonomic revision of Acaciella (Leguminosae, Mimosoideae)

The genus Acaciella Britton & Rose is reinstated, neotropical with the highest species diversity along the Pacific coast of Mexico, characterised by three features exceptional in Acacia Miller: unarmed plants, lack extrafloral nectaries and pollen polyads 8-celled.
