LOLIUM PERENNE (L.), var. ITALICUM (Braun). 
(Italian Rye Grass). 
Culms often 3 feet high, leafy, terminating in a rigid 
spike-like panicle, nearly a foot long; spikelets seven to 
eleven-flowered, placed edgewise in a groove of the 
rhachis; inner and lower empty glume ovate, reduced in 
size or absent; upper empty glume linear, equaling the 
spikelet; flowering glumes five-nerved, roughisli, tipped 
with a straight awn. 
This introduced grass is occasionally seen in irrigated 
meadows on the plains. It is in flower about the middle 
of July. It is considered the most valuable of the rye 
grasses, standing drought remarkably well.
