Taxon discussion

Carex enneastachya is endemic from the Tropical Andes from Colombia to Bolivia. As C. brehmeri , it belongs to sect. Carex Phacocystis Dumort. (see above).

In Ecuador, Carex enneastachya was reported only from a handful locations in Cajas National Park at Azuay Province. Here we present additional records for another three provinces. Originally conceived as a narrowly distributed taxon, this species was listed as EN in the Ecuadorian Red List of Endemic plants under the name C. azuayae . However, C. azuayae was already synonymized by Wheeler (1998) to C. enneastachya , which effectively expands its range to other South American countries. As a consequence, this plant should not be listed as an Ecuadorian endemic and its threatened status needs revision.
