Senna (Leguminosae) is a large, widespread genus that includes species with enantiostylous, asymmetric flowers and species with extrafloral nectaries. [] Key Result Our results support the monophyly of only one (Psilorhegma) of the six currently recognized sections, while Chamaefistula, Peiranisia, and Senna are paraphyletic, and monotypic Astroites and Paradictyon are nested within two of the seven major clades identified by our molecular phylogeny.

Figures and Tables from this paper

The evolutionary history of Mimosa (Leguminosae): toward a phylogeny of the sensitive plants.
TLDR
A preliminary phylogenetic framework for Mimosa is established that can be used to infer patterns of morphological evolution and relationships and which provides pointers toward a revised infrageneric classification.
Phylogenetic relationships within Chamaecrista sect. Xerocalyx (Leguminosae, Caesalpinioideae) inferred from the cpDNA trnE-trnT intergenic spacer and nrDNA ITS sequences
Chamaecrista belongs to subtribe Cassiinae (Caesalpinioideae), and it comprises over 330 species, divided into six sections. The section Xerocalyx has been subjected to a profound taxonomic shuffling
The evolutionary history of Senna ser. Aphyllae (Leguminosae–Caesalpinioideae), an endemic clade of southern South America
TLDR
The ancestral character state reconstructions suggest that, in addition to the loss of leaves in adult plants, series Aphyllae evolved various morphological features, such as fastigiate, thickened or decumbent–subdecumbent branches during the colonization and establishment in different arid and semiarid lands in South America.
Diversity in Anthers and Stigmas in the Buzz‐Pollinated Genus Senna (Leguminosae, Cassiinae)
TLDR
Novel morphological characteristics are identified that are congruent with the clades supported by the molecular phylogeny of the large genus Senna, particularly in the androecium and gynoecium.
Phylogenetic patterns and diversification in the caesalpinioid legumes
TLDR
The chloroplast matK gene, and the trnL and 3′-trnK introns for 153 genera of caesalpinioid legumes are sequenced and Parsimony and Bayesian phylogenetic analyses of these data support the monophyly of several major groups within the Caesalpinsia clades.
Extrafloral nectaries in Leguminosae: phylogenetic distribution, morphological diversity and evolution
TLDR
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.
Phylogenetic placement of Podolotus suggests independent origin of lomentaceous fruits in Coronilla and Hippocrepis (Leguminosae: Loteae).
TLDR
The data support the view that lomentaceous fruits evolved in Coronilla independently from all other members of Loteae that bear this fruit type, and suggest that Podolotus is closest to Coronillas.
Combined phylogenetic analyses reveal interfamilial relationships and patterns of floral evolution in the eudicot order Fabales
TLDR
The development of papilionate flowers, and the evolutionary context in which these phenotypes appeared in Leguminosae and Polygalaceae, shows that the morphologies are convergent rather than synapomorphic within Fabales.

Phylogenetic Relationships in the Caesalpinioideae (Leguminosae) as Inferred from Chloroplast trnL Intron Sequences
TLDR
A phylogenetic analysis of the chloroplast trnL intron analysis for 223 Caesalpinioideae suggests that basal legumes are extremely diverse in their floral morphology, and that presence of simple, actinomorphic flowers may be a derived feature in a number of lineages in the family.
A phylogeny of legumes (Leguminosae) based on analysis of the plastid matK gene resolves many well-supported subclades within the family.
TLDR
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.
Molecular phylogeny and floral evolution of Penaeaceae, Oliniaceae, Rhynchocalycaceae, and Alzateaceae (Myrtales).
TLDR
The resulting phylogenies suggest that the monospecific New World Alzateaceae is sister to the three African taxa and that the MONOSpecific Rhynchocalycaceae is Sister to Oliniaceae/Penaeaceae, while flowers of both families are most parsimoniously interpreted as having an obhaplostemonous organization.
rbcL and Legume Phylogeny, with Particular Reference to Phaseoleae, Millettieae, and Allies
TLDR
A parsimony analysis was conducted on 319 rbcL sequences, and not surprisingly showed both tribes to be polyphyletic, though with all taxa except Wisteria and allied Millettieae belonging to a single well supported clade.
Biogeography and floral evolution of baobabs (Adansonia, Bombacaceae) as inferred from multiple data sets.
TLDR
The phylogeny does not permit unambiguous reconstruction of floral evolution but suggests the plausible hypothesis that hawkmoth pollination was ancestral in Adansonia and that there were two parallel switches to pollination by mammals in the genus.
Tribal and intergeneric relationships of Mesechiteae (Apocynoideae, Apocynaceae): evidence from three noncoding plastid DNA regions and morphology.
TLDR
A maximum parsimony analysis was conducted based on DNA sequences and morphological data for 23 taxa of Mesechiteae and 11 taxa from other tribes of Apocynoideae to test the monophyly of the tribe and evaluate intratribal relationships.
Trends in evolution of floral ontogeny in Cassia sensu stricto, Senna, and Chamaecrista(Leguminosae: Caesalpinioideae: Cassieae: Cassiinae); a study in convergence
TLDR
Convergence is shown among the three genera, based on intergeneric dissimilarities in early floral ontogeny resulting in similarities at anthesis.
A phenetic study of Cassia sensu lato (Leguminosae-Caesalpinioideae: Cassieae: Cassiinae) in Thailand
TLDR
The three most important characters that separate the three genera are filament length, fruit length, and ovary stalk length, together with some qualitative characters, were useful in constructing an identification key to these genera.
Secretory structures on the leaf rachis of Caesalpinieae and Mimosoideae (Leguminosae): implications for the evolution of nectary glands.
TLDR
The occurrence of rachis glands in seven of the ten species of the Paleotropical genus Erythrophleum, a member of the Dimorphandra group of caesalpinioids thought to include the sister group(s) of mimosoids, and of the patches of trichomes are primitive homologues of more organized glands are discussed.
Chloroplast DNA phylogeny, reticulate evolution, and biogeography of Paeonia (Paeoniaceae).
TLDR
A refined hypothesis of species phylogeny of section Paeonia was proposed by considering the discordance between the nuclear and cpDNA phylogenies to be results of hybrid speciation followed by inheritance of cpDNA of one parent and fixation of ITS sequences of another parent.
