Lolium perenne, L. — Perennial Rye-^rass, Ray-j;rass, Enj^lish 

 Rye-^rass, Darnel. 



This is a perennial, as is indicated by its name, and 

 has been cultivated in England for more than two 

 hundred years, making- it one of the oldest of cultivated 

 fodder grasses. It differs from Italian Rye-grass in 

 being distinctly stoloniferous, its darker green leaves 

 which are simply folded (not rolled) in the bud, and 

 beardless head or spike. 



Perennial Rye-grass is less tall than the Italian and 

 is probably not so valuable a grass for this region. In 

 moist, cool climates it is a most excellent pasture grass 

 for heavy soils. "Its duration depends very much on 

 the nature of the soil and the climate; on dry light 

 soils, it disappears after the second year ; while in 

 moist climates, on good heavy soils, it will persist for 

 seven years, or even longer." (Steblcr & Schroter.) 



Lolium temulentum, Linn — Darnel, Poison Rye-grass, Bearded 

 Darnel. 

 An annual grass from Europe, occasionally found 

 in grain fields. It may be recognized by its gen- 

 eral resemblance to Lolium Lialicum. The grain of 

 this species "contains a narcotic principle, soluble 

 in ether, which causes eruptions, trembling, and 

 confusion of sight in man and in flesh-eating ani- 

 mals, but it does not affect swine or horned cattle."
