CHAPTER XIX 



Tribe VII. PHALARIDE^ 



A SMALL tribe of about 6 genera in the 

 cooler parts of the northern hemisphere and 

 of Australasia. Spikelets with 1 fertile 

 floret and a pair of staminate or neutral 

 florets below. In Phalaris, the pair of sterile 

 florets appear as small scales within the 

 glumes. In Savastana the lateral florets (1 

 or 2) are staminate and as large as the 

 fertile floret. Only 3 genera are found in 

 the United States.
