introduced and cultivated to some extent by way of 

 experiment. Its spikes are simple, linear ; spikelets 



awnless ; stems one foot high, 

 stiff, smooth; root perennial, 

 fibrous, and tufted. Flowers 

 in July. It is said to be a 

 valuable permanent pasture 

 grass ; but cattle seldom eat 

 it after it is ripe, on account 

 of its wiry stems. On dry, 

 hard soils and hiUs, pastured

 is tender and nutritious. A 

 magnified spikelet is shown in 

 Fig. 121. 



The stems of this grass are 

 used for the manufacture of 

 plat for Leghorn hats and 

 bonnets, and have the reputa-

 to Italian straw. They are 

 gathered green when in blos-
