This is similar in appearance to the Tall Meadow grass, but is 

 smaller, with a lighter panicle and smaller flowers. It has also much 

 the same general range. It usually grows along the wet margins of 

 streams and in swamps. It is nutritious and might be advantageously 

 mixed with other grasses in wet grounds. It is especially abund- 

 ant in the Rocky Mountains.

Spikelets about five flowered, outer glumes membranaceous, three-

 smooth, five-nerved or ribbed (when mature strongly so,) becoming 

 scarious at the apex, and two to five toothed or mucronate from 

 the excurrent nerves; palet as long as its glume, two keeled and 

 ciliate on the keels, acute or bifid at the tip. The base of each 

 flower is surrounded by a ring of short hairs. Fanicle large, with
