NorEs ON NOMENCLATURE 
In applying the rules of nomenclature of the “ American Code” 
to the species of Carex found in North America, it has been found 
that a considerable number of species have been known by names 
which are not tenable. For some of these species valid names 
exist but to others new names must be given, and for various 
reasons certain other necessary changes in names must also be 
made, as follows :
