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. …

A new classification of Carex (Cyperaceae) subgenera supported by a HybSeq backbone phylogenetic tree
The field of systematics is experiencing a new molecular revolution driven by the increased availability of high-throughput sequencing technologies. As these techniques become more affordable, the increased genomic resources have increasingly far-reaching implications for our understanding of the Tree of Life. With c. 2000 species, Carex (Cyperaceae) is one of...Villaverde, Tamara ; Jiménez-Mejías, Pedro ; Luceño, Modesto ; Waterway, Marcia J ; Kim, Sangtae …

Tackling Rapid Radiations With Targeted Sequencing
In phylogenetic studies across angiosperms, at various taxonomic levels, polytomies have persisted despite efforts to resolve them by increasing sampling of taxa and loci. The large amount of genomic data now available and statistical tools to analyze them provide unprecedented power for phylogenetic inference. Targeted sequencing has emerged as a...
