This species has been confounded with C. acuta o whic 
it is closely related. But it differs in its larger a Packer 
spikes densely flowered, in its wider leaves, in its less acute 
and even obtuse angled culm scarcely. scabrous, and in its 
spikes being much lighter enn It is described by 
Schkuhr, but he has given no figure of it. Our plant 
agrees with a specimen from Sweden 
The three preceding species with C. stricta and C, crinita 
pee: a very natural subdivision in this genus. Excepting C. 
crinita, they strongly resemble each ote, and will not be. 
distinguished without particular attention.
