BRIZA. 



255 



recently detected by Professor Graham in a field of 



Italian Eye-grass near Grantham, on the Firth of Forth, 



in a most luxuriant state, the 



stems three feet high, the 



panicles three inches long, 



and the foliage abundant in 



proportion. This growth 



was doubtless from foreign 



seed, imported along with 



that of Eye-grass, which had 



been brought from the South 



of France. 



The Eough Dog's-tail has 

 been found in the Shetland 

 Islands, of a very dwarfed form, and also in Northumber- 

 land and Durham. 



Its foreign homes are France, Spain, Portugal, Italy, 

 and North Africa. 



It flowers at the end of June, and ripens its seed in 

 August. 



The bristly head and long awns are its distinctive 

 features. There is an Indian species, C. corocana, the 

 seeds of which are eaten instead of rice in times of 

 scarcity.
