Taxon discussion

Carex phalaroides is a Neotropical endemic widely distributed from northern Patagonia to Colombia and Venezuela, with an isolated occurrence known in Guatemala ( Jiménez-Mejías et al. 2018). It belongs to sect. Junciformes Kük. (subg. Junciformes Psyllophorae (Degl.) Peterm.), one of the few Carex groups with a remarkably relatively high species diversity in South America ( Benítez-Benítez et al. 2021a). Carex phalaroides is an anomalous member of sect. Carex Junciformes from a morphological point of view as its inflorescence is constituted by several spikes (instead of a solitary one in the remainder of the section) ( Benítez-Benítez et al. 2021a, Morales-Alonso et al., in prep.).

Previously known from just a handful locations in Ecuador, our field campaign has resulted in the collection of several additional populations; thus, Carex phalaroides seems to be more widely distributed along Ecuadorian high Andean grasslands. However, to date, it has been collected just a few times (see comments under General considerations at the end of the manuscript), as depicted by its scarce representation in herbaria (just one additional specimen from Ecuador: MO-5869195, Imbabura, Cotacachi-Cayapas, after revising the full collections of K, NY, MO and US).
