28 PHLETJM ALPINUM. 



green and white with dull purple, varying in length from half 

 an inch to an inch and a half. Spikelets close together, dim- 

 inutive and numerous. Calyx of two equal-length glumes, with 

 wide membranous margins; the keels, which are green, are 

 fringed with short white hairs; the glumes end in a rough awn, 

 of rather inore .than half the length of the glume. Floret 

 consisting of a pair of membranous paleae, the exterior one 

 being egg-shaped, five-ribbed; keel hirsute; small rough dorsal 

 awn; inner palea somewhat shorter. Length from six to twelve 

 inches. 



Comes into bloom in July, and the seed becomes ripe before 

 September. 



The present Grass bears some resemblance to Alopecurus 

 alpinus, yet the latter species has the panicle silky, the glumes 

 of the calyx destitute of awns, and the floret possessing only 

 one palea. 



I amj indebted to Mr. Joseph Sidebotham, of Manchester, for 

 the specimen illustrated, which was gathered on the Clova 

 mountains.
