 This is a foreign grass which has become extensively naturalized, 



not only in the older States but in many places in the western and 

 southwestern Territories. It is found in waste and cultivated 

 grounds and on roadsides, growing in thick tufts, which spread out 

 over the ground by means of the geniculate and decumbent culms. 

 The culms are from 1 to 2 feet long, the lower joints bent and giv- 

 ing rise to long branches. The sheaths are shorter than the inter- 

 nodes, the leaves from 3 to 6 inches long. The panicle is fre- 

 quently 4 or 5 inches long, oblong or pyramidal, somewhat open, 

 but full-flowered ; the branches irregularly single or in pairs, 

 branched and flowering nearly to the base. The spikelets are ob- 

 long or lanceolate one-fourth to one-half inch long, and ten to twenty 

 flowered when well developed. The empty glumes are smaller than 

 the flowering ones, rough on the keel, acutish. The flowering glumes 

 are one line long, ovate, rather obtuse, and strongly three-nerved. 

 The palets are shorter than their glumes, narrow, the sides reflexed 

 and the margin ciliate. This grass is said to have a disagreeable 

 odor when fresh. It produces an abundance of foliage and is ap- 

 parently an annual, reaching maturity late in the season. We are 

 not aware that its agricultural value has been tested.
