Hab. In meadows, growing with C. digitalis and the ordinary 

 variety of C. hirsuta. Philipstown, Highlands of New-

Obs. This plant might be taken for a distinct species, were it 

 not carefully examined in a living state. Its spikelets are 

 three fourths of an inch long, slender, and supported by 

 peduncles half an inch in length. The leaves are only 

 slightly pubescent under a high magnifier.
