| Abstract: | Two new species ofCarex (Cyperaceae) are described from southern South America.Carex transandina occurs in naturally-deposited rock talus and scree in southwestern Chile andC. austroamericana occurs in the Patagonian steppe in Chile and Argentina. In the past, specimens ofC. austroamericana have been erroneously referred toC. andina var.subabscondita Kük., and it is shown here that the latter entity is conspecific withC. nelmesiana Barros. The taxonomy ofC. nelmesiana is presented and its relationship to other members ofCarex sect.Junciformes (Boeckl.) Kük. is discussed. |
