Tipo y Observaciones

Material Tipo: Lectotype (designated by Molina et al., 2008): ‘Carex n e m o r o s a , f i b r o s a r a d i c e, c a u l e e x q u i s i t e triangulari, spica longa divulsa seu interrupta, capitulis solitariis praeterquam ultimo’ in Micheli, Nov Pl. Gen.: t. 33, f. 10. 1729. Epitype (designated by Molina et al., 2008): ‘Gram. Cyp. spicatum minus spicâ longâ/divulsâ seu interrupta Ray 1279. 2 Petiver’ (No. 17274, FI-M). [Molina et al., Bot. J. Linn. Soc. 156: 395. 2008].
Observaciones: Iconography: Figures 2X, 3X. See additional figures in Barros (1935: 208; 1947: tab. 182), Pedersen (1968: 331) and Molina et al. (2008: 396). Etymology: From the Latin divulsus, parted, in reference to the elongated inflorescences, with long internodes between the lower spikes. Notes: This species has been reported a long time ago as an introduced species in Argentina (Barros, 1935). The Argentinian plants are a fairly good fit for the narrowest concept of C. divulsa as presented in Molina et al. (2008). Thus the South American populations fall within the largest portion of the variation of the species. In any case, further genetic studies would be desirable to confirm the status of the Río de la Plata plants. Selected additional references: Ball & Reznicek (2002), Jermy et al. (2007), Luceño et al. (2008) and Molina et al. (2008) (descriptions).
