An updated checklist of Araceae, Leguminosae and Myrtaceae of the department of Boyacá, Colombia, including keys to genera and new occurrence records.
Baseline checklists for the Leguminosae (Fabaceae), Araceae and Myrtaceae from the Colombian department of Boyacá are available from the Catalogue of Plants and Lichens of Colombia. These lists were supplemented by thorough herbarium and literature searches by a collaborative group of local and international experts, and further enhanced by local... -

Precipitation is the main axis of tropical plant phylogenetic turnover across space and time.
Early natural historians—Comte de Buffon, von Humboldt, and De Candolle—established environment and geography as two principal axes determining the distribution of groups of organisms, laying the foundations for biogeography over the subsequent 200 years, yet the relative importance of these two axes remains unresolved. Leveraging phylogenomic and global species distribution... -

Boliviadendron, a new segregate genus of mimosoid legume (Leguminosae, Caesalpinioideae, mimosoid clade) narrowly endemic to the interior Andean valleys of Bolivia.
Phylogenetic analyses of DNA sequence data sampling all species of alongside representatives of genera of the Inga and Albizia clades of the larger ingoid clade of mimosoid legumes (sensu Koenen et al. 2020) confirm the non-monophyly of the genus . We show that is placed in the Albizia clade, while... -

Disintegration of the genus Prosopis L. (Leguminosae, Caesalpinioideae, mimosoid clade).
Robust evidence from phylogenomic analyses of 997 nuclear genes has recently shown, beyond doubt, that the genus is polyphyletic with three separate lineages, each with affinities to other genera of mimosoids: (i) is an isolated lineage placed in the grade of , and that subtends the core mimosoid clade; (ii)... -

Re-circumscription of the mimosoid genus Entada including new combinations for all species of the phylogenetically nested Elephantorrhiza (Leguminosae, Caesalpinioideae, mimosoid clade).
Recent phylogenomic analyses of 997 nuclear genes support the long-held view that the genus is congeneric with . is resolved as monophyletic only if the genus is subsumed within it. The two genera were distinguished solely by relatively minor differences in the mode of dehiscence of the fruits (a craspedium...O’Donnell, Shawn A. ; Ringelberg, Jens J. ; Lewis, Gwilym P.

Phylogenomic analysis of 997 nuclear genes reveals the need for extensive generic re-delimitation in Caesalpinioideae (Leguminosae).
Subfamily Caesalpinioideae with ca. 4,600 species in 152 genera is the second-largest subfamily of legumes (Leguminosae) and forms an ecologically and economically important group of trees, shrubs and lianas with a pantropical distribution. Despite major advances in the last few decades towards aligning genera with clades across Caesalpinioideae, generic delimitation... -

Molecular and Morphological Analysis Supports the Separation of Robrichia as a Genus Distinct from Enterolobium (Leguminosae: Caesalpinioideae: Mimosoid Clade).
As currently circumscribed, the legume genus comprises 11 species in two sections: sect. and sect. , with an overall distribution from Mexico to Argentina and a centre of diversity in Amazonia. In the absence of the characteristic indehiscent fruits, is difficult to distinguish from other genera in the ingoid clade,...Rodrigues de Souza, Élvia ; Ranielly Monteiro Luz, Anne ; Rocha, Lamarck ; Lewis, Gwilym P.

Botanical Monography in the Anthropocene
Botanical monographs have been the gold standard for communicating comprehensive systematic information about plants for over 300 years. Monographs catalyse species discovery, biodiversity documentation and conservation, and facilitate downstream research on wild and cultivated plant species. Increased availability of DNA sequence data and digitised resources now provide powerful resources for...Grace, Olwen M. ; Pérez-Escobar, Oscar A. ; Lucas, Eve J. ; Vorontsova, Maria S. ; Lewis, Gwilym P. …

How diverse is heterochromatin in the Caesalpinia group? Cytogenomic characterization of Erythrostemon hughesii Gagnon & G.P. Lewis (Leguminosae: Caesalpinioideae)
Main conclusion Cytogenomic characterization of Erythrostemon hughesii reveals a heterogeneity of repeats in its subtelomeric heterochromatin. Comparative analyses with other Caesalpinia group species reveal a significant reduction in the abundance of Ty3-gypsy/Chromovirus Tekay retrotransposons during its evolution. In numerically stable karyotypes, repetitive DNA variability is one of the main causes...Mata-Sucre, Yennifer ; Sader, Mariela ; Van-Lume, Brena ; Gagnon, Edeline ; Pedrosa-Harand, Andrea …

Hybrid capture of 964 nuclear genes resolves evolutionary relationships in the mimosoid legumes and reveals the polytomous origins of a large pantropical radiation
PREMISE Targeted enrichment methods facilitate sequencing of hundreds of nuclear loci to enhance phylogenetic resolution and elucidate why some parts of the “tree of life” are difficult (if not impossible) to resolve. The mimosoid legumes are a prominent pantropical clade of ~3300 species of woody angiosperms for which previous phylogenies... -

Revisiting the cytomolecular evolution of the Caesalpinia group (Leguminosae): a broad sampling reveals new correlations between cytogenetic and environmental variables
The pantropical Caesalpinia group includes 225 species in 27 monophyletic genera, and the group has undergone recent phylogenetic, taxonomic and biogeographic revisions. Previous works have reported a diverse pattern of heterochromatin distribution related to ecological niche/geographic distribution, and variation in genome size also correlated with environmental variables. In order to... -

Evolutionary diversity in tropical tree communities peaks at intermediate precipitation
Global patterns of species and evolutionary diversity in plants are primarily determined by a temperature gradient, but precipitation gradients may be more important within the tropics, where plant species richness is positively associated with the amount of rainfall. The impact of precipitation on the distribution of evolutionary diversity, however, is...Neves, Danilo M. ; Dexter, Kyle G. ; Baker, Timothy R. ; Coelho de Souza, Fernanda ; Oliveira-Filho, Ary T. …
