too few characters to distinguish it very easily from its re- 
lated species. By Schk. it is finely figured, and is clearly 
a very distinct species.

Spiculis sessilibus alternis, ovatis approximatis 5—8, 
apice foemineis, bracteatis; capsulis subrotundo-ovatis ros- 
tratis alatis striatis bidentatis margine ciliato-serratis, squa- 
ma ovato-lanceolata nuncronata majoribus. 
Culm 15—30 inches high, triangular, leafy, giabrous; 
leaves sheathing, linear, shorter than the culm; spikelets 
rather near, cylindric-ovate and at length globose, with 
small bracts; fruit ovate, or roundish ovate, beaked, di- 
verging compressed, ciliate-serrate ; pistillate. scale three- 
fourths the length of the fruit, green on the keel, mucro- 
nate. The mucronate point is short and often disappears in 
the mature state ofthe fruit. Stigmas 2. 
Flowers in May—grows in cultivated fields and drier 
meadows. 
This species is nearly allied to C. straminea; but may 
readily be distinguished from it by its shorter, more round, 
and less widely winged fruit, and by its scale, which is 
ovate-lanceolate and mucronate. The scale of C. strami- 
nea is lanceolate or oblong-lanceolate, and its fruit less di- 
verging than that of this species. From C. scoparia and 
C. lagopodioides it is readily distinguished by the charac- 
ters already given.

*This, as well as several ofour well known species, is not described by Wahl. 
or in Rees’ Cyc. In the latter, the popular descriptions are generally ex- 
cellent; but the article was written before the work of Schk. was com- 
pleted, and the references to the figs. of Schk. are acknowledged to be 
‘taken from the work of Wahl.
