Far from uncommon in moist woods and thickets, and about 

 ditches and rivers under the shade of trees, especially in places 

 liable to be overflowed. 



Stems three to six feet high, terminating in a 'large, copiously 

 branched, but rather compact panicle from six to eight inches or 

 more in length. Leaves broad, harsh and rigid. The general 

 character of the inflorescence is rather peculiar : the branches of 

 the panicle being all directed to one side and the spikelets having 

 a similar determination, render it not unlike an exaggerated 

 specimen of that of the Rough Cock's-foot Grass, Dactylis glo- 

 merata, to which Dr. Withering compared it in the first edition of 

 his "Arrangement of British Plants." The compressed awl- shaped 

 glumes are rigid and rough with bristles, especially on the keel, 

 as shown in the magnified figure at a. The palese are thin, almost 

 membranaceous ; and the awn of the outer one arises from about 

 the middle of its back, as seen in figure b. Close examination will 

 often enable us to detect the rudiment of a second flower, although 

 it has been frequently remarked upon as absent in this species. 



Perennial. Flowers in July.

Panicle erect, loose. Spikelets scattered, spreading, Glumes 

 lanceolate, their keel smooth. Basal hairs longer than the palese. 

 Awn from the base of the notch of the outer palea, very short.

This is a more local species than C. Epigejos, though found, 

 like that, in various parts of the kingdom ; always in moist, and 

 more frequently in shady situations, but occasionally in more ex- 

 posed ones, especially in fenny districts. Root somewhat creeping. 

 Stems slender, three to five feet high. Leaves narrow, linear. 

 Panicle four to six inches long ; its branches and spikelets com- 

 paratively loose, and expanding on all sides. Spikelets shining, 

 with a tinge of rose-purple, which renders the panicle, when in 

 full flower, very conspicuous. The glumes, flgure a, are less at- 

 tenuated than those of the last species, and nearly smooth. The 

 short awn of the outer palea, in figure b, is not dorsal, but extends 

 from the bottom of the terminating notch, in many instances 

 scarcely rising beyond the points of the latter. 



Perennial. Flowers in July. 



A second, rudimentary, flower seems never to have been detected 

 in this species.
