Perennial. June, July. 



Many botanists liave taken this grass for a variety of our Glyceria 

 ^fluitans, and more perhaps have overlooked it for Lotium perenne; 

 yet it is certainly distinct f om both, as Mr. Curtis has well de- 

 monstrated. The root is fibrous. Stems several, erect, 2 feet 

 high, simple, leafy, round, very smooth, of a pale green like the 

 rest of the plant. Leaves linear, narrow, flat, smooth j with 

 long smooth sheaths ; and extremely short stipulas, embracing 

 the stem at each side with a small acute auricle, as in F.gigantea. 

 Spike a span long, or more, generally unbranched, of many al- 

 ternate, nearly or quite sessile, oblique, smooth, pale, upright, 

 compressed spikelets, on a wavy, angular, common stalk, chan- 

 nelled alternately to receive them, and rough at the angles, which 

 droops more or less in the upper part. Valves of the calyx very 

 unequal ; the smaller lodged in each channel of the stalk, linear- 

 lanceolate, varying in size, sometimes wanting ; larger opposite, 

 many-ribbed, bluntish. Florets \0 or 1 2, cylindrical j smooth 

 below ; compressed and keeled at the summit, with 2 slight ribs 

 at each side, and roughish, ending in an acute membrane, some- 

 times attended by a small point, like the rudiment of an awn ; 

 inner valve nearly as large, downy at the ribs, Germen obovate. 

 Styles very short. Stigmas densely feathery along the upper 

 side. Tiie seeds are rarelv perfected.
