It has been recently segregated from the closely-related Holarctic C. maritima Gunnerus ( Jimenez-Mejias et al. 2021b ). Carex melanocystis is the only Southern Hemisphere representative of the Disticha clade (subg. Carex Vignea (T.Lestib) Peterm.), where both species are nested. These are the first confirmed records of C. melanocystis for Ecuador, which become the northernmost limit of the species.
