1896, and of other recent writers. 
Common in the northeastern part of the United States are two 
closely related sedges, one or the other of which has been treated 
as Carex virescens Muhl, by authors who have had occasion to deal 
with them. Unfortunately, there has been considerable diversity 
of opinion as to which plant should bear the name, and the facts 
on which the question must be decided seem somewhat contradic- 
tory. So much is this so that Professor Fernald (Rhodora 8: 
182, 183) and Mr. Bicknell (Bull. Torrey Club 35: 488, 489) 
have reached opposite conclusions.
