Targeted sequencing supports morphology and embryo features in resolving the classification of Cyperaceae tribe Fuireneae s.l.
Molecular phylogenetic studies based on Sanger sequences have shown that Cyperaceae tribe Fuireneae s.l. is paraphyletic. However, taxonomic sampling in these studies has been poor, topologies have been inconsistent, and support for the backbone of trees has been weak. Moreover, uncertainty still surrounds the morphological limits of Schoenoplectiella, a genus... -

Delimiting the genera of the Ficinia Clade (Cypereae, Cyperaceae) based on molecular phylogenetic data
Generic delimitations in the Ficinia Clade of tribe Cypereae are revisited. In particular, we aim to establish the placement of annual species currently included in Isolepis of which the phylogenetic position is uncertain. Phylogenetic inference is based on two nuclear markers (ETS, ITS) and five plastid markers (the genes matK,...Muasya, A. Muthama ; Larridon, Isabel

A framework infrageneric classification of Carex (Cyperaceae) and its organizing principles
Phylogenetic studies of Carex L. (Cyperaceae) have consistently demonstrated that most subgenera and sections are para‐ or polyphyletic. Yet taxonomists continue to use subgenera and sections in Carex classification. Why? The Global Carex Group here takes the position that the historical and continued use of subgenera and sections serves to...Roalson, Eric H. ; Jiménez‐Mejías, Pedro ; Hipp, Andrew L. ; Benítez‐Benítez, Carmen ; Bruederle, Leo P. …

The evolutionary history of sedges (Cyperaceae) in Madagascar
Aim Madagascar is renowned for its unparalleled biodiversity and endemism. With many ecosystems under threat, research is urgently needed on its unique plant diversity. This applies both to Madagascar's forests and treeless vegetation types. Sedges (Cyperaceae) are among the top 10 species‐richest angiosperm families in Madagascar (310 native species, 38%... -

Resolving generic limits in Cyperaceae tribe Abildgaardieae using targeted sequencing
Morphological characterizations of genera in Cyperaceae tribe Abildgaardieae have been highly problematic and the subject of much debate. Earlier molecular phylogenetic studies based on Sanger sequencing and a limited sampling have indicated that several generic circumscriptions are not monophyletic. Here, we provide the first phylogenetic hypothesis for Abildgaardieae using targeted...Larridon, Isabel ; Zuntini, Alexandre R. ; Barrett, Russell L. ; Wilson, Karen L. ; Bruhl, Jeremy J. …

Combining the small South American genus Androtrichum into Cyperus (Cyperaceae)
Background and aims – Molecular phylogenetic studies have provided a clearer understanding of the complex relationships within the family Cyperaceae. These studies have consistently shown that 12 allied genera are nested in the genus Cyperus. However, early Sanger sequencing-based phylogenies that included the two species of the small South American...Pereira-Silva, Luciana ; Trevisan, Rafael ; Rodrigues, Ana Claudia ; Larridon, Isabel

What drives diversification in a pantropical plant lineage with extraordinary capacity for long‐distance dispersal and colonization?
Aim Colonization of new areas may entail shifts in diversification rates linked to biogeographical movement (dispersification), which may involve niche evolution if species were not exapted to new environments. Scleria (Cyperaceae) includes c. 250 species and has a pantropical distribution suggesting an extraordinary capacity for long‐distance dispersal and colonization. We...Larridon, Isabel ; Galán Díaz, Javier ; Bauters, Kenneth ; Escudero, Marcial

Introgression across evolutionary scales suggests reticulation contributes to Amazonian tree diversity
Hybridisation has the potential to generate or homogenize biodiversity and is a particularly common phenomenon in plants, with an estimated 25% of plant species undergoing inter‐specific gene flow. However, hybridisation in Amazonia’s megadiverse tree flora was assumed to be extremely rare despite extensive sympatry between closely related species, and its...
