Glyceria Nervata, Tkin. 



Panicle loose spreading, branches very slender capillary, at 

 length pendulous; spikelets ovate, five to six flowered; flowers 

 obtuse, ligule oblong ovate. — " Trin. in Act. Petrop. 6, ser. 1, p. 

 367;" Glyceria Michmixii Knnth. Gram., 1, p.343; Poa nervata 

 Wild., sp. 1, p. 389; Poa Mich. 1, p. 69; Poalineata, Pers. Syn. 

 l,p. 89; Poa parviflora Pursh., 1, p. 80; Briza Canadensis JSTutt. 

 Gen. 1, p. 69. Culm three to four feet high, erect; leaves six to 

 twelve inches long, narrow, scabrous, smooth; panicle large; 

 spikelets about two lines long, often tinged with purple, flowers 

 caducous; glumes unequal, small; palea ovate, nearly equal, 

 strongly seven nerved. 



This grass is common in many sections of the Northern and 

 Western States, abounding in wet meadows and wet places in 

 open situations. All kinds of stock are fond of it. It forms an ex- 

 cellent hay, and is readily eaten by horses, cattle or sheep. In 

 Western New-York it flowers generally during the last week in 

 June or the first week in July; and it should be cut for hay be- 

 fore the seeds arrive at maturity, as they fall off" soon after becom- 

 ing ripe. The seeds, when ripe, feel much like sand, when 

 handled. We can confidently recommend its cultivation, as we 

 have tested its valuable properties, both for hay and pastur- 

 age. Its growth in many places would save much expense in 

 draining.
