resembling the F. duriuscula, to which it seems nearly 

 allied, differing only in the length of the awns, and the 

 glaucous colour of the whole plant. The considera- 

 ble produce it affords, and the nutritive powers it ap- 

 pears to possess, joined to its early growth, are quali- 

 ties which strongly recommend it to further trial.
