ARRHENATHERUM. Beauvois. There is only a solitary example of this 

 genus in this country, namely, the Arrhenatherum avenaceum. It has the 

 habit of the Oat Grass, yet differing in the number and structure of its 

 florets. The name is derived from two Greek words, signifying male and 

 awn. 



A PRODUCTIVE agricultural Grass, especially on clayey soil, 

 yet a species but little grown in this country. It will thrive 

 well under trees, and is sometimes a troublesome weed in corn 

 fields.
