This species is very accurately figured in Schk. but it is 
not easily distinguished from its allied species by any de- 
scription, except that given by Muh. ‘That it is related to 
C. ovalis or leporina is remarked by Muh. and indeed it 
was formerly considered by him as the same species and 
thus named, as I learn from the Rev. Mr. Schweinitz. It is 
however very different from C. ovalis or leporinain the shape 
of its fruit and scale and spikelets. Pursh asks whether 
C. viridula, Mx. may not be C. scoparia. This cannot be, 
as C. viridula appears to have about three spikelets and is 
very nearly related to C. scirpoides, Schk. It is far more 
probable that the plant described by Mx.’as C. leporina, L. 
is the same as C. scoparia. For, although Mx. states that 
the plant is destitute of bracts, this is often the appearance 
ef C. scoparia, as its bracts are deciduous. An additional 
reason is that the C. leporina of Wahl. and Agardh has a 
sub-leafy bract under the lowest spikelet. It is remarked also 
by Mx. that the spikelets are greenish or yellowish, a char- 
acter particularly to be observed in C. scoparia, as well as 
the locality assigned by Mx. viz. from Carolina to Canada.

Culm scabrous above, three sided, leafy, often exceeding 
two feet in height; leaves sheathing at the base, longer than 
the culm, linear-lanceolate; spikelets 8—20, cylindric- 
ovate, approximate, sometimes much aggregated into a head ; 
a large bract under the lowest spikelet, often longer than 
the culm, deciduous; fruit erect, lanceolate, nerved, slight- 
ly margined, bicuspidate, distinctly scabrous or ciliate-ser- 
rate on the margin; scale ovate-lanceolate, a little more 
than half the length of the fruit with a green keel. The 
whole plant has a faint green colour. Flowers in May— 
found in wet places. Stigmas 2. . 
This species is related to C. ovalis and C. scoparia. 
From both, however, it is readily distinguished by the pre-
