Abstract The classification of the legume family proposed here addresses long‐known non‐monophyly traditionally recognised subfamily Caesalpinioideae, by recognising six robustly supported monophyletic subfamilies. This new uses as its framework most comprehensive phylogenetic analyses legumes to date, based on plastid matK gene sequences, and including near‐complete sampling genera (698 currently 765 genera) ca. 20% (3696) known species. region has been widely sequenced across legumes, in...
Abstract The Leguminosae, the third–largest angiosperm family, has a global distribution and high ecological economic impor tance. We examine how legume systematic research community might join forces to produce comprehensive phylogenetic estimate for ca. 751 genera 19,500 species of legumes then translate it into phylogeny–based classification. review current state knowledge phylogeny highlight where problems lie, example in taxon sampling resolution. approaches from bioinformatics...
ABSTRACT Tropical Africa is home to an astonishing biodiversity occurring in a variety of ecosystems. Past climatic change and geological events have impacted the evolution diversification this biodiversity. During last two decades, around 90 dated molecular phylogenies different clades across animals plants been published leading increased understanding speciation processes generating tropical African In parallel, extended palaeoclimatic records together with detailed numerical simulations...
Understanding the patterns of biodiversity distribution and what influences them is a fundamental pre-requisite for effective conservation sustainable utilisation biodiversity. Such knowledge increasingly urgent as responds to ongoing effects global climate change. Nowhere this more acute than in species-rich tropical Africa, where so little known about plant diversity its distribution. In paper, we use RAINBIO - one largest mega-databases African vascular species distributions ever compiled...
The tropical vegetation of Africa is characterized by high levels species diversity but undergoing important shifts in response to ongoing climate change and increasing anthropogenic pressures. Although our knowledge plant distribution patterns the African tropics has been improving over years, it remains limited. Here we present RAINBIO, a unique comprehensive mega-database georeferenced records for vascular plants continental Africa. geographic focus database region south Sahel north...
Summary Determining where species diversify (cradles) and persist (museums) over evolutionary time is fundamental to understanding the distribution of biodiversity for conservation prioritization. Here, we identify cradles museums angiosperm generic diversity across tropical Africa, one most biodiverse regions on Earth. Regions containing nonrandom concentrations young (neo‐) old (paleo‐) endemic taxa were identified using data 1719 genera combined with a newly generated time‐calibrated...
The tropical African flora is highly biodiverse, but around one in every three species potentially threatened with extinction.
Abstract Aim To delineate bioregions in tropical Africa and determine whether different plant growth forms (trees, terrestrial herbs, lianas shrubs) display the same pattern of regionalization, diversity endemism as whole flora. Location Tropical (excl. Madagascar), from 20° N to 25° S. Taxon Vascular plants. Methods Analyses were based on occurrences 24,719 vascular species distributed across extracted RAINBIO database. The majority (93%) classified into four forms: trees, shrubs lianas....
Legume systematists have been making great progress in understanding evolutionary relationships within the Leguminosae (Fabaceae), third largest family of flowering plants. As phylogenetic picture has become clearer, so too need for a revised classification family. The organization into three subfamilies and 42 tribes is outdated evolutionarily misleading. traditionally recognized subfamilies, Caesalpinioideae, Mimosoideae, Papilionoideae, do not adequately represent occasion Sixth...
Detarioideae (81 genera, c. 760 species) is one of the six Leguminosae subfamilies recently reinstated by Legume Phylogeny Working Group. This subfamily displays high morphological variability and early branching clades in evolution legumes. Using previously published newly generated sequences from four loci (matK-trnK, rpL16, trnG-trnG2G ITS), we develop a new densely sampled phylogeny to assess generic relationships tribal delimitations within Detarioideae. The ITS phylogenetic trees are...

The Cross River-Sanaga River interval is known to be importance primate geography. Is it also important for plants? characteristics area may more a product Highlands than flora lowland Guinea: work needed decide this.
The Leguminosae (or Fabaceae) currently comprises 751 genera. In most of the world's herbaria genera are arranged by old, non-phylogenetic, classification systems which, while offering insights into morphological similarity, make no explicit statement as to evolutionary relationships. While classifications based on morphology useful tools for plant identification, they do not offer predictive value that phylogenetically linear sequences provide. legume collection c.750,000 specimens in...
Objectives Species Distribution Models (SDMs) are used to produce predictions of potential Leguminosae diversity in West Central Africa. Those evaluated subsequently using expert opinion. The established methodology combining all SDMs is refined assess species within five defined vegetation types. Potential thus predicted for each type respectively. primary aim the new define, more detail, areas richness conservation planning. Methodology Using Maxent, based on a suite 14 environmental...
Abstract Recent studies have shown that Acacia is polyphyletic and must be split into five genera. Proposal 1584 would retypify : the type of Australian taxon A . penninervis conserved over current lectotype ( scorpioides ) an African taxon. We disagree with recommendation Spermatophyte Committee to endorse this proposal. Contrary Article 14.12 ICBN , no detailed case against conservation was presented in 1584. maintain there are strong arguments conservation, such as large number countries...
Historically, many authors of regional accounts the Leguminosae (Fabaceae) tribe Cercideae divided caesalpinioid genus Bauhinia sens. lat. into several segregate genera including Phanera. However, during last fifty years, has more often been recognised as a broadly circumscribed taxon with Phanera reduced to subgenus The reinstatement at generic rank based on molecular and morphological evidence now widely accepted, resulting in need for new combinations taxa described Bauhinia. Some those...
For much of the last thirty years, caesalpinioid genus Bauhinia has been recognised by numerous authors as a broadly circumscribed, ecologically, morphologically and palynologically diverse pantropical taxon, comprising several subgenera. One these, subg. Phanera recently reinstated at generic rank based on synthesis morphological molecular data. Nevertheless, there remains considerable diversity within Phanera. Following review palynological studies in conjunction with careful...
The genus Bauhinia sens. lat. formerly accommodated numerous species that have now been transferred to one of several segregate genera. One those genera, Schnella, includes all neotropical liana with tendrils. This study comprises a summary the taxonomic and nomenclatural history presents list names accepted under including 12 new combinations. We recognise here total 53 taxa 47 species. Distribution details for each taxon are given, illustrated map showing numbers within TDWG regions...
Legume subfamily Caesalpinioideae accommodates approximately 2250 species in 171 genera which traditionally are placed four tribes: Caesalpinieae, Cassieae, Cercideae and Detarieae. The monophyletic tribe Detarieae includes the Amherstieae subclade contains about 55 genera. Our knowledge of relationships among those is good some cases but for many other phylogenetic have been unclear. non-monophyletic nature at least two amherstioid genera, Cynometra Hymenostegia has also complicated...
Abstract Daniellia (Leguminosae: Caesalpinioideae) is a genus of ten species medium to large trees from tropical and subtropical Africa. In contrast earlier accounts, D. mortehanii treated here as synonym pymertii, oblonga, which previously has been by some authors thurifera, accepted. addition, we describe new glandulosa. Quantitative characters such receptacle length, petiole width, sepal largest leaflet length have used aid differentiation following the results recent morphometric studies...
We have observed among the holdings of Hymenostegia (Leguminosae: Caesalpinioideae) in several major herbaria that many specimens determined as H. klainei Pierre ex Pellegr. are not identified correctly and instead represent undescribed taxa. speculate misidentifications may be a direct consequence sole use leaf characters to distinguish species dichotomous keys two regional treatments genus. Two such previously unrecognised taxa, both new from Gabon, elegans Wieringa Mackinder robusta...
Englerophytum and Synsepalum are two closely related genera of trees shrubs from the African tropics. Previous molecular studies have shown that these collectively form a clade within subfamily Chrysophylloideae (Sapotaceae). However, little is known about inter-relationships taxa Englerophytum–Synsepalum clade. In this study, nuclear ribosomal DNA plastid trnH–psbA sequences were used to estimate phylogeny Results indicate consists six major lineages, composed solely genus four Synsepalum....
The genus Donella Pierre ex Baill. is here reinstated and Austrogambeya Aubrév. is, for the first time, placed in synonymy based on findings of recent combined molecular morphological studies. Seventeen species are recognised, two which, ranirisonii L.Gaut. & Mackinder D. humbertii Capuron L.Gaut., from Madagascar, described time. flowers ambrensis delphinensis as fruits guereliana.
