Beckmajjnia, Host. 



Spikelets subsessile, crowded in two rows upon the short simple 

 or compound branches of the long, narrow panicle ; consisting of 

 two perfect flowers, the terminal one only fertile, (or in American 

 specimens the lower flower is suppressed,) and two subcoriaceous, 

 obovate or boat-shaped, compressed and inflated empty glumes. The 

 glume of the perfect flower or flowers is lanceolate, acute or acumi- 

 nate, and of rather thinner texture than the empty glumes.

 west of the Mississippi. 



Panicum, Linn. 



Spikelets with one perfect terminal flower, and usually a second 

 one which is male only or rudimentary. Outer empty glumes two, 

 one of which is smaller than the other, often very small, or rarely 

 wanting, membranaceous. The glume of the perfect flower with 

 its palet are usually of a coriaceous texture, and obtuse or obtusish. 

 The second flower when present is membranaceous. Inflorescence 

 spicate or paniculate. 



The name is probably derived from the Latin word pants, bread, 

 because some species were used, and are still used, for bread-making. 

 The species of this genus are very numerous, (300 or more on the 

 globe,) and of widely different appearance. We have about 50 

 native species, most of which have little practical value except as 

 adding more or less to the wild forage of our woods and fields. 

 But some species, both native and foreign, are of very high agricul- 

 tural value.
