than the ovate, or nearly elliptic, black scale; upper spike 
wholly staminate, or only staminate below On C. atrata, 
the scale is longer than the fruit, and ovate-lanceolate—the 
spikes larger, less clustered, pedunculate, and often cernuous. 
On C. Locate oe UDPSE spike is staminate, some- 
times the next with a few staminaté florets at the apex,—the 
lower spikes long, Sar. subsessile, subremote, erect, and 
sparsely fruited. This species is very different from C. sara- 
telis, which has two stigmas, while this has three, and is too 
different to be confounded with any of those now mentioned, 
except by those whe have not the means of comparing them:

The accompanying figure of this species was politely 1 i 
nished by Dr. Torrey. _ It will serve to make botanists bet- 
ter acquainted with this new and interesting species. The © 
pistillate spikes vary from two to three. The obtuseness and 
even roundness of the staminate scale, and the peculiar form 
of the pistillate scale, are very characteristic.

The oS of this variety is, that one, two, or three 
small spikes branch from the bottom of the lowest spike — 
These branched spikelets have their fruit and scales like the 
others. 
Note. Although the characiers of the European plant are 
found on all the varieties of this species in our country, yet 
our plant grows to a greater size, often two feet in height, and 
the spikes are much longer, though they are not much larger. 
It is common along our streams, in large cespitose masses; 
and it seems to occur generally in this way in Europe. 
in Essex county, } Mass, a small variety is found in moist soil, 
which is not cespitose, and which closely resembles speci- 
mens from Europe. The pistillate spikes are short and 
thick, and much like one of the figures of this species by 
Schk.
