 of a purplish colour ; leaves linear, acute, flat, on the back 

 and towards the point roughish, of a light green or glaucous

 green to a purple colour ; calyx twice the size of the corolla,

The produce of foliage in the spring from this grass is com- 

 paratively nothing, as is the case with the latter-math produce. 

 The root-leaves are remarkably short in this species of canary- 

 grass, and the culms are numerous. At the time of flowering, the 

 produce may be said to consist entirely of culms. It grows 

 naturally in dry sandy places ; said to have been first discovered 

 in Great Britain by Mr. Woodward and Mr. Crow, near Swafl'ham, 

 Norfolk, in 1780. It is also a native of Germany, where it grows 

 in pastures, orchards, hills, and dry sandy barren places. It is 

 evidently unfit for cultivation in the farm, as the above produce 

 constitutes what it yields in one season, and which, when com- 

 pared with that of most other grasses affecting a similar soil, proves 

 greatly inferior. It ripens plenty of seed for its propagation. It 

 thrives best on a sandy loam. The structure of the panicle is 

 useful, to shew the last form of a panicle next to a spike. In this
