Here, we present relevant records of three species that are new at national level (Carex jamesonii Boott and C. pseudomacloviana G.A.Wheeler for Bolivia, and C. ruthsatziae G.A.Wheeler for Argentina), six new regional records for Bolivia (C. acutata Boott, C. bonariensis Desf. ex Poir., C. crassiflora Kük., C. feddeana H.Pfeiff., C. fuscula d’Urv., and C. pachamamae Jim.Mejías & Reznicek), and additional records of rare plants (C. pachamamae and C. ruthsatziae). We describe C. giovanniana Jim.Mejías as a new species previously misidentified as C. subdivulsa (Kük.) G.A.Wheeler. In addition, we perform the typification for four names (C. acutata, C. crassiflora, C. jamesonii, and C. tessellata Spruce ex C.B.Clarke). Comments on the taxonomy of C. ruthsatziae are provided. We synonymise C. obtusisquama (Gross) G.A.Wheeler & S.Beck to C. crassiflora, and C. tessellata to C. acutata.
