The leaves are bristle-form, slender, rather stiff, and erect 
till near maturity. It is rather smaller than the specimens 
from Europe. In other respects it does not differ. In the 
form and colour of the fruit and scale, and in the hyaline, 
obtuse, leafless sheaths, the resemblance is complete. :

Spikes long-cylindric, attenuated above, one to three, more 
or less pedunculate, often approximate ; large and leafy bract 
under the lower spike ; leaves appear to be less rigid. 
Found in N. Carolina—Schw. This appears to be only 
a variety of C. squarrosa—the fruit has three stigmas, though 
it is referred in the An. Tab. to those which have only ts 
and the scales do not differ. As all the descriptions © 
squarrosa implied there was only one spike, this was patural- 
ly considered distinct. But the common variety is found to 
ve from one to three spikes, similarly situated to these, a5 
shown in the Monograph, Pl. 27, fig. 2. The specimens 1 
received from Dr. Barratt, collected in the Highlands of N. 
Y. have one, two, and three spikes. It becomes necessary t© 
amend the description of C. squarrosa, L. by this difference 
in the number of spikes. The lower ones too appeat 2 
have much fewer staminate florets than the highest, or t0 be 
destitute of them. The figure of ©. squarrosa, Vol. XI. tab: 
I. fig. 29, shows the common variety before the fruit is ma~
