[Jiménez-Mejías et al., Bot.J.Linn.Soc. XX: 2
Observaciones: Iconography: Figures 2K, 3K. See additional figures
in Barros (1947: tab. 178) and Silveira & LonghiWagner (2012: 410, utricle with the corky base
underdeveloped).
Etymology: From Uruguay.
Notes: C. uruguensis is a poorly understood taxon.
Herbarium vouchers have been often misidentified
as C. sororia. In addition, the name has been also used
to refer to the superficially similar C. giovanniana,
from which it clearly differs by the utricle characters
indicated in the key. The different varieties described
and accepted by different authors seem to correspond
with variation in the inflorescence configuration
(see Discussion) and utricle size, and probably have
little taxonomic value (if any).
Carex uruguensis seems to be confined to the
lowlands of the Paraná and Uruguay river basins,
reaching a few coastal stations in Brazil at its
northernmost limit (Silveira & Longhi-Wagner,
2012; Jiménez-Mejías & Silva, 2020). The reports
from Bolivia (Jørgensen et al., 2014) are based on
specimens of C. giovanniana (Jiménez-Mejías et al.,
2020). It has been also cited from AGW (Tucumán;
Barros, 1935, 1947; Zuloaga et al., 2020) but these
records are potentially misidentifications too and
need confirmation. A thorough revision of herbarium
material would be desirable to better define the
geographical limits of the species.
