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.Expand
Phylogeny reconstruction in the Caesalpinieae grade (Leguminosae) based on duplicated copies of the sucrose synthase gene and plastid markers.
TLDR
This study confirms that the Caesalpinieae grade is an artificial group, and highlights the need for further analyses of lineages at the base of the Mimosoideae, and investigates the utility of several nuclear markers developed from genomic studies in the Papilionoideae. Expand
A molecular phylogeny of the vataireoid legumes underscores floral evolvability that is general to many early-branching papilionoid lineages.
TLDR
Luetzelburgia, Sweetia, Vatairea, and Vatairopsis are unequivocally resolved as the "vataireoid" clade and fruit and vegetative traits are found to be more phylogenetically conserved than many floral traits. Expand
Phylogenetic Relationships of the Northeastern South American Brownea Clade of Tribe Detarieae (Leguminosae: Caesalpinioideae) Based on Morphology and Molecular Data
TLDR
Traditional generic, species, and intraspecies boundaries are assessed and reevaluated using the results of the combined phylogenetic analysis of selected members of the Brownea clade. Expand
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. Expand
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 shufflingExpand
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. Expand
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. Expand
Phylogenetic relationships of Ruteae (Rutaceae): new evidence from the chloroplast genome and comparisons with non-molecular data.
TLDR
The phylogenetic analyses determined that Haplophyllum and Ruta form reciprocally exclusive monophyletic groups and that Dictamnus is not closely related to the other genera of Ruteae. Expand
Phylogenetics of Anthyllis (Leguminosae: Papilionoideae: Loteae): Partial incongruence between nuclear and plastid markers, a long branch problem and implications for morphological evolution.
TLDR
Bayesian and maximum parsimony analysis of a concatenated plastid dataset recovered well-resolved trees that are topologically similar, with many clades supported by unique indels, and infer up to six major clades in Anthyllis that are morphologically well-characterized, and which could be recognized as sections. Expand
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. Expand

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. Expand
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. Expand
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. Expand
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. Expand
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. Expand
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. Expand
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. Expand
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. Expand
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. Expand
THE FLORAL BIOLOGY OF CASSIA DIDYMOBOTRYA AND C. AURICULATA (CAESALPINIACEAE)
TLDR
It is proposed that style deflections may clear access of the pollinator to the anthers and protect female parts from injury by a vibrating heavy-bodied visitor and an effect of enantiostyly in promotion of outcrossing is considered. Expand
