 4-sided ; spikelcts crowded, broad-ovate, about 4-flowcred ; glumes ventricose ; 

 awns of the iippcr palca generally longer than the flowers.—® and @ This is 

 without doubt the most valuable plant of the order ; is universally cultivated, 

 and may be regarded as naturalized. Many varieties are known to farmers, 

 of which the most important are
