“…For example, individual species or clades marked by radially symmetric flowers are independently derived multiple times across basal Papilionoideae, a large assemblage of florally heterogeneous lineages dominated by bilaterally symmetric flower morphology (Figs. 7-9) (Pennington & al., 2000;Cardoso & al., 2012bCardoso & al., , 2013aRamos & al., 2016). Similarly, while Mimosoideae are the most conspicuously biodiverse clade with radially symmetric flowers, other closely related lineages scattered across the MCC clade also have radially symmetric, mimosoid-like flowers ( Fig.…”

The classification of the legume family proposed here addresses the long‐known non‐monophyly of the traditionally recognised subfamily Caesalpinioideae, by recognising six robustly supported monophyletic subfamilies. This new classification uses as its framework the most comprehensive phylogenetic analyses of legumes to date, based on plastid matK gene sequences, and including near‐complete sampling of genera (698 of the currently recognised 765 genera) and ca. 20% (3696) of known species. The matK gene region has been the most widely sequenced across the legumes, and in most legume lineages, this gene region is sufficiently variable to yield well‐supported clades. This analysis resolves the same major clades as in other phylogenies of whole plastid and nuclear gene sets (with much sparser taxon sampling). Our analysis improves upon previous studies that have used large phylogenies of the Leguminosae for addressing evolutionary questions, because it maximises generic sampling and provides a phylogenetic tree that is based on a fully curated set of sequences that are vouchered and taxonomically validated. The phylogenetic trees obtained and the underlying data are available to browse and download, facilitating subsequent analyses that require evolutionary trees. Here we propose a new community‐endorsed classification of the family that reflects the phylogenetic structure that is consistently resolved and recognises six subfamilies in Leguminosae: a recircumscribed Caesalpinioideae DC., Cercidoideae Legume Phylogeny Working Group (stat. nov.), Detarioideae Burmeist., Dialioideae Legume Phylogeny Working Group (stat. nov.), Duparquetioideae Legume Phylogeny Working Group (stat. nov.), and Papilionoideae DC. The traditionally recognised subfamily Mimosoideae is a distinct clade nested within the recircumscribed Caesalpinioideae and is referred to informally as the mimosoid clade pending a forthcoming formal tribal and/or clade‐based classification of the new Caesalpinioideae. We provide a key for subfamily identification, descriptions with diagnostic charactertistics for the subfamilies, figures illustrating their floral and fruit diversity, and lists of genera by subfamily. This new classification of Leguminosae represents a consensus view of the international legume systematics community; it invokes both compromise and practicality of use.

Ecology, geography, morphology, and a combined phylogenetic analysis of DNA sequence variation support the recognition of the new species Luetzelburgia jacana (Leguminosae, Papilionoideae, vataireoid clade). This species is found in the inter‐Andean Rio Cauca Valley in Colombia. Phylogenetic analyses of nine plastid and nuclear DNA sequences from 44 accessions representing all known Luetzelburgia species show that L. jacana is sister to the rest of the genus and has a mean estimated stem age of ca. 4 Ma, much older than other Luetzelburgia species. Luetzelburgia jacana is distinguished by a combination of mostly 7–9‐foliolate, glabrous leaves with leaflets obtuse to shortly acute at the apex, flowers up to 9.6 mm long, and samaras bearing two small lateral wings on the seed chamber. Luetzelburgia jacana, along with two other earliest‐branching species in the genus, L. guaissara and L. trialata, are geographical outliers in the genus, with L. jacana having the northernmost distribution and L. guaissara and L. trialata having the southernmost distributions. These three earliest‐branching species are also ecological outliers within Luetzelburgia by occurring in wetter and less seasonal settings than other species. The discovery of L. jacana resolves these three earliest‐branching species in Luetzelburgia as ecologically transitional between most species of the vataireoid clade that inhabit wet forests and most species of Luetzelburgia that inhabit highly seasonal dry forests and woodlands.

“…This find implies that similar floral organization in Brongniartieae and core Genistoids should have resulted from independent evolution from a weakly papilionate flower involving free stamens and incompletely differentiated petals like those found in Leptolobieae and in the early-branching lineages of the Genistoids s.l. clade (Cardoso et al, 2012c(Cardoso et al, , 2013a, demonstrating once again the labile nature of flower architecture in the early-branching lineages of the papilionoid legumes (Cardoso et al, 2013b). Also, it would imply an ancient divergence between the New World lineages of Brongniartieae and Leptolobieae with respect to the predominantly African-Eurasian core Genistoids (Lavin et al, 2005).…”

ABSTRACTThe papilionoid legume tribe Brongniartieae comprises a collection of 13 genera with disparate morphologies that were previously positioned in at least three remotely related tribes. The Brongniartieae displays a wide geographical disjunction between Australia and the New World and previous phylogenetic studies had provided conflicting results about the relationships between the American and Australian genera. We carry out phylogenetic analyses of (1) a plastid matK dataset extensively sampled across legumes to solve the enigmatic relationship of the Cuban-endemic monospecific genus Behaimia; and (2) multilocus datasets with focus on all genera ever referred toBrongniartieae. These analyses resulted in a well-resolved and strongly-supported phylogenetic tree of the Brongniartieae. Increased molecular sampling in papilionoid legume phylogeny has dramatically changed our understanding of the evolution and taxonomic classification in this species rich lineage of economically and ecologically important legumes (family Leguminosae).The prevailing traditional hypotheses of generic relationships assumed that the papilionate flower would be a signature of the most "derived" groups, whereas the more caesalpinioid and mimosoid-like floral organizations, involving undifferentiated petals and free stamens, marked mostly the "primitive" tribes within the subfamily Papilionoideae (Polhill, 1981a). Hence, such an evolutionary perspective has largely influenced the way in which the modern subfamily, tribe, and even genus-level classification of legumes was built (LPWG, 2013(LPWG, , 2017. In the past 15 years, molecular phylogenetic studies have underpinned dramatic taxonomic changes after revealing unexpected relationships, suggesting that floral architecture is relatively labile in the early-branching papilionoid lineages (e.g. Pennington et al., 2001;Wojciechowski et al., 2004; Cardoso et al., 2012aCardoso et al., , 2013aCardoso et al., , 2015Ramos et al., 2016).The recent examples of broad phylogenetic re-alignments that were unexpectedly revealed in the early-branching genera of Papilionoideae (Cardoso et al., 2012a(Cardoso et al., , 2012b(Cardoso et al., , 2012c(Cardoso et al., , 2013a(Cardoso et al., , 2017Ramos et al., 2016; Castellanos et al., in press) are not an exception across legumes. For example, dramatic shuffling in the placement of genera has also been necessary within the species-rich canavanine-accumulating clade (Wojciechowski et al., 2004;Silva et al., 2012;Sirichamorn et al., ...
