Chorological, nomenclatural and taxonomic notes on Carex (Cyperaceae) from Bolivia and northern Argentina

摘要

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 Kuk., C. feddeana H.Pfeiff., C. fuscula d'Urv., and C. pachamamae Jim.Mejias & Reznicek), and additional records of rare plants (C. pachamamae and C. ruthsatziae). We describe C. giovanniana Jim.Mejias as a new species previously misidentified as C. subdivulsa (Kuk.) 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.
