Carex sagei (Cyperaceae), nombre correcto de C. barrosii

Abstract

The holotype of Carex sagei comes from central Chile, and this name has long been treated as a synonym of C. fuscula . Recent study indicates, however, that C. sagei is referrable to Carex section Ceratocystis, whereas C. fuscula belongs in section Spirostachyae. It is also demonstrated that C. sagei is the correct name for plants currently called C. barrosii . Carex sagei is known from Argentina, Chile, and the Falkland Islands (Islas Malvinas), where it frequents hydric habitats, such as marshes, wet meadows, and the margins of lakes, from near sea level to about 850 m.
