Systematics, classification, and evolution of sedges

Understanding evolutionary relationships and classification of Carex, one of the largest flowering plant groups of the northern hemisphere is key to conservation, restoration, and ecological study in the group.


We are investigating the evolutionary history of the world's estimated 2,000 sedge species (Carex, Cyperacae).We are utilizing a combination of DNA barcoding approaches and phylogenomic approaches to unravel the phylogeny and taxonomy of one of the temperate zone's largest flowering plant genera, one that is key to wetland ecosystem function and biodiversity. Our work entails collaboration with more than 30 colleagues in more than 10 countries and has led to the formation of The Global Carex Group, an international collaborative body focused on the genus.
