The genus Carex, the sedges, is one of the largest genera of flowering plants, containing of over 2000 species, according to the Royal Botanic Gardens at Kew.[1] In May 2015, the Global Carex Group argued for a broader circumscription of Carex, which added all the species formerly classified in Cymophyllus (1 species), Kobresia (c. 60 species), Schoenoxiphium (c. 15 species) and Uncinia (c. 70 species).[2] As of May 2024, all the currently recognised species (including hybrid species) in the genus Carex are given below:
