Notes: A South American endemic species previously believed to be closely related to the superficially resembling C. microglochin Wahlenb. Recent phylogenetic studies ( Escudero et al. 2010, Gehrke et al. 2010, Global Carex Group 2016) have demonstrated that C. camptoglochin is allied to the species belonging to the sections Aciculares and Junciformes, two groups that are mainly distributed in South America and with a few disjunct species in New Zealand ( Global Carex Group 2016).
