Taxon discussion

Carex collumanthus is endemic from the northern half of the cordillera, where it has been reported from Venezuela, Colombia, Peru and Bolivia ( Wheeler 2002). It belongs to sect. Carex Abditispicae G. A. Wheeler, a group of species with Andean-Patagonian distribution that is nested within the Flacca Clade (subg. Carex Carex ).

Here, we report the species for the first time in Ecuador, which was somehow expected since the plant is known from Colombia and Peru.
