This species, originally described by Rudge in 1803, from a 
Newfoundland specimen in Herb. Banks, escaped observation till 
Dr. Gray discovered it in the State of New York, and described 
it in the ‘ Annals of the Lyceum’ in 1834, under the name of C. 
blepliarophora. Kunth and Drejer were not acquainted with it. 
It would seem to be local in its range in the States, and was not 
found by the explorers of the Arctic regions. 
Dr. Gray places it between C. sylvatica and C. miliacea. It 
differs from the Sylvaticce in the rigid hairy leaves and culm, the 
ferruginous scales without aristae, the non-membranous orifice of 
the pei'igynium, the short stigmata and spikes; but in the occa¬ 
sional tendency to geminate spikes, and in the punctate perigy¬ 
nium, it has some affinity with O. Cherokeensis; and to C. longi- 
rostris in the abbreviate, almost obsolete, bracteal vaginse. Tuck- 
erman places it in his group Flexiles with G. GheroJceensis, and 
Carey adopts this arrangement, associating O. ccvpillaris with it, 
saying nothing of G. Cherokeensis, which did not come within the 
limits of Gray’s Flora. It is remarkably constant in the solitary 
male spike, and in the entire absence of male florets on the female 
spikes. I have never observed any such at their base, as stated 
by Carey.
