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... -

Challenges of applying monophyly in the phylogenetic shallows: taxonomic reappraisal of the Dactylorhiza maculata group.
The first study of the taxonomically critical European orchid genus to use next-generation DNA sequencing generated the statistically best-supported reconstruction of its phylogeny to date. However, the two competing topologies obtained within the monophyletic Section differed radically in the placement of the s.s.– clade. Both topologies showed to be nested...
