The produce of this grass is very coarse, and the weight of the crop, therefore, though con- 

 siderable, IS comparatively of no value. It is a native of Siberia, and withstands the effects of 

 the severest continued frost, but not sudden changes from frost to mild weather. It requires to 

 he sown every year, and treated as an annual. It comes into flower the second season, about 

 the second or third week in June, and continues tc emit flowering culms till autumn. The seed 

 IS ripe in about three weeks after flowering, A light rich siliceous soil appears to be best adapted 



to Its growth. In the Hortus Kewensis, it is said to have been cultivated in 1758, by Mr. 

 rhihp Miller. ^ • ? j
