Culm 18 — 30 inches high, acutely triangular, very 

 scabrous above, furrowed and striate on the sides, 

 leafy ; leaves linear, three lines broad, channelled, striate, 

 nearly as long as the culm, shorter below ; sheath gla- 

 brous, striate, white and membranous on the side of the 

 stipule ; stipule ovate, acute ; spike decompound, two 

 inches long; spikelets many, aggregated into several ap- 

 proximate spikes, ovate-cylindric, obtuse, becoming taw- 

 ney, all bracted, staminate above ; bracts rather long and 

 narrow and scabrous under the spikes, short and setace- 

 ous under the spikelets, and giving to the spike a brisily 

 appearance ; fruit ovate-lanceolate, acuminate, bifid, 

 slightly plano-convex, often slightly 3 — 5 nerved, grow- 

 ing yellow, scabrous on the margin, rather loose, and 

 somewhat diverging ; pistillate scale ovate-lanceolate, 

 tawney, green on the keel, and with its awn about the length 

 of the fruit. 



Flowers in June and July — matures its fruit in Au- 

 gust — -grows in clusters in wet upland meadows with 

 C. multiflora and C. stipata ; but is a later plant than ei- 

 ther. 



Note. — In both the preceding species, as well as some 

 others, the awn or cuspidate part of the scale is very 

 liable to be broken off before the fruit is matured ; and 

 the examination of this part requires much care and cau- 

 tion.
