Premise of research. Despite recent progress on the systematics of the Leguminosae, the relationships between some genera, as well as their circumscriptions, remain uncertain. Here we investigate the relationships between Stryphnodendron and closely related genera in the Piptadenia group, a clade of problematic taxonomy for which a robust phylogenetic hypothesis is still lacking. Methodology. Taxonomic sampling included 23 species of Stryphnodendron (77% of the genus) and representatives of… 

A new generic system for the pantropical Caesalpinia group (Leguminosae)

New phylogenetic analyses show that the current classification of the Caesalpinia group into 21 genera needs to be revised, and a new generic classification is presented including a key for the identification of genera, full generic descriptions, illustrations, and the nomenclatural transfer of species to their correct genus.

Wood anatomy of seven Stryphnodendron species (Mimosoid clade - Caesalpinioideae - Leguminosae)

The wood anatomy of the seven species of Stryphnodendron most frequently found in Brazilian forest remnants is described and compared, in order to identify which anatomical features can be used in their segregation.

Misleading fruits: The non-monophyly of Pseudopiptadenia and Pityrocarpa supports generic re-circumscriptions and a new genus within mimosoid legumes

Recognition of Parapiptadenia, Pityrocarpa and Marlimorimia as distinct genera is also supported by combinations of morphological traits, several of which were previously overlooked.

Is chiropterophily an evolutionary dead end? A phylogenetic test in the pantropical genus Parkia (Leguminosae, Caesalpinioideae, mimosoid clade)

The results indicate that the ancestral capitulum in the genus had three types of flowers and a morphology associated with bat-pollination in both the Paleotropics and Neotropics, and entomophily, as seen in some Neotropical species of Parkia, has been derived from a bat- pollinated ancestor.

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.

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.

Hybrid capture of 964 nuclear genes resolves evolutionary relationships in the mimosoid legumes and reveals the polytomous origins of a large pantropical radiation

The selection of 964 nuclear genes greatly improves phylogenetic resolution across the mimosoid phylogeny and shows that the ingoid clade can be resolved into several well‐supported clades, but nearly all loci show lack of phylogenetic signal for some of the deeper internodes within the ingoids.

The complete chloroplast genome of Stryphnodendron adstringens (Leguminosae - Caesalpinioideae): comparative analysis with related Mimosoid species

The chloroplast genome of S. adstringens was reconstructed using de novo and referenced-based assembly of paired-end reads generated by shotgun sequencing of total genomic DNA and indicated that gene content and synteny are highly conserved in the clade.

New Insights into the Systematics and Biology of Brazilian Leguminosae (Fabaceae)

A major aim of the LPWG is to deliver a new, phylogenetically underpinned classification of Leguminosae, with an anticipated increase in the number of subfamilies recognized, because it has long been known that subfamilyCaesalpinioideae is not monophyletic.

A phylogeny of legumes (Leguminosae) based on analysis of the plastid matK gene resolves many well-supported subclades within the family.

Analysis of the matK data consistently resolves but modestly supports a clade comprising papilionoid taxa that accumulate canavanine in the seeds, which suggests a single origin for the biosynthesis of this most commonly produced of the nonprotein amino acids in legumes.

Phylogenetic relationships in the tribe Millettieae and allies in the subfamily Papilionoideae (Leguminosae) were reconstructed from chloroplast trnK/matK sequences, suggesting that the presence of a pseudoraceme or pseudopanicle and the accumulation of nonprotein amino acids are phylogenetically informative for Milletties and allies with only a few exceptions.
