I ; l TRIANDRIA— DIGYNIA. Lolium. 



In meadows, pastures, and waste ground, common. 



y and $ found occasionally near Norwich. 



Perennial. June. 



Root of a few simple fibres. Stems several, a foot high, more or 

 less, round, smooth, rigid, leafy, with purplish tumid joints, the 

 lowermost of which are bent. Leaves dark green, linear, pointed, 

 flat, smooth, striated. Sheaths compressed, striated, smooth. 

 Stipula short, entire, acutely auricled at each side. Spike nearly 

 upright, various in luxuriance, with a smooth common stalk. 

 Spikelets numerous, alternate, erect- usually many-flowered. 

 Outer valve of the corolla linear-lanceolate, keeled, acute, gene- 

 rally with a short awn, just below the cloven tip, scarcely dis- 

 cernible, and frequently wanting. Styles very short. Seed

/3 is merely a starved state of the plant, with 3 or 4 florets only, 

 but still the spikelet extends beyond the calyx, y has a branched, 

 or compound, general spike. $ bears a short, broad, ovate, close 

 spike. Sometimes the florets are, here and there, viviparous. 



Well known to the farmer by the name of Rye-grass, or Ray- 

 grass. It yields an early crop of hay upon high or sandy lands ; 

 and makes a fine turf, which however is said not to be lasting, 

 except on a rich soil. Much valuable information concerning its 

 cultivation and merits is collected by Professor Hooker, in his 

 Continuation of the Fl. Londinensis. The result seems to be that 

 this grass is best suited to the light land of Norfolk, where it 

 first obtained its reputation.
