The produce of this species, and the nutritive 

 matter that it affords, are equal to those of the Festuca 

 ovina at the time the seed is ripe; they equally delight 

 in dry soils. The greater bulk of grass in proportion 

 to the weight, with the comparative coarseness of the 

 foliage, render the Poa eristata inferior to the Festuca 

 ovina.

This species is strictly annual ; it is likewise sub- 

 ject to the rust; and the above being its whole pro- 

 duce for one year, it ranks as a very inferior grass.
