The plant I have found in this neighbourhood is suggested 
by Mr. Collins to be a variety of Scirpus debilis ; and on com- 
paring it with the latter plant, a specimen of which I have re- 
ceived from that gentleman, it does really appear to be so. It 
is not, perhaps, the S. debilis of Pursh ; or if so, it is imper- 
fectly described by him ; neither does it appear to be the plant 
intended by Mr. Elliot, under that name, referring to the 
debilis, Muhl’s Cat. Dr. Muhlenberg seems to describe it, 
under his debilis ; for his description extends evidently to two 
varieties, if not species. I have, however, for the present 
quoted his characters, and referred my plant to his name. In 
the same bog where Furiena squarrosa, and Eriophorum polys- 
tachium grow, Jersey. August.
