I have seen no specimens of these plants that afford us any sa¬ 
tisfactory means of rightly judging of them, and they must be 
left for future observation. The filiform culms, elongated leaves, 
and squamaeform bracts, contrast perceptibly with G. aphylla.

I see no essential difference in the specimens of this species 
from its various localities, in all of which the accessory lower 
spike is occasionally found, thus separating it strictly from the 
Psyllophorce, and allying it to the Sphce.ridophorce of Drejer. 
In the Franconia specimen alluded to, the solitary female floret 
on the male plant may be regarded as the rudiment of a female 
spike. The achenia I have examined have been triquetrous, or in 
a few instances tetraquetrous, the central angle occasionally de¬ 
pressed. Mr. Oakes, I believe, first discovered the species in the 
States, in 1827, in the White Mountains of New Hampshire, 
since which time it has been found in other localities of that State, 
in "Vermont and Maine. Mr. Wright (U. S. North Pacific Expe¬ 
dition) found it on the Arakamtchetchene Island, Behring Straits, 
—the only authority that I am aware of for its being a native of 
Asia. It is not included in the FI. Rossica, or among the plants 
of the Amur.
