    Tipo y Observaciones

    Material Tipo: Holotype (destroyed): ARGENTINA: Entre Ríos, Paso de Duranguillo, 24 Jan 1878, Lorentz 1564 (B, photograph at F-0BN013409!). Lectotype (here designated): ARGENTINA: Entre Ríos, Paso de Duranguillo, 24 Jan 1878, Lorentz 1564 (CORD-00002111 digital image!). Remaining syntypes: ARGENTINA: Entre Ríos, Concepción del Uruguay, Quinta de Sagastume, Oct 1885, Lorentz 1685, CORD-00002110 digital image! photograph at F (F-0BN013409!) and US. [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.
