The general appearance of this phxnt indicates the inferior comparative value manifested in the 

 above details. It appears, according to the information quoted above, from Mr. Curtis, to be chiefly 

 confined to the sea-coasts. I have never met with it in a wild state. It does not appear to be of much 

 value to the Agriculturist. Probably, however, in such places as are expensed to the spray of 

 the ocean, it may succeed better, and afford a greater produce ; its nutritive powers are far from 

 being very inconsiderable. It ripens an abundance of seed, which vegetates freely. In the fio-ure 

 and disposition of the florets and panicle, it seems to connect the Agrostis verticillata, Agrostis 

 stolonifera, var. angustifolia, and Agrostis alba, in a series. 



It flowers in the first week of August, and the seed is ripe about the end of the same 

 month. 



Ag 



Rock Bent, Upright Bent 



Trichoduim rupestre. (Schrader.) 



Specific character: Panicle branches subdivided, roughish; calyx valves acuminate; blossom 

 one valve, awned; awn fixed a little above the base. 



0^*.— This species of Bent is distinguished from the Agrostis vulgaris, and Agrostis canim, 



to which in habit it approaches, by the corolla or blossom being but of one valve ; from 



the Agrostis nivea, vel Trichodium niveum, by the erect disposition of the stem, and the awn 



which is fixed but a little above the base of the valve: the valve has likewise two short 



awn-like points, which are a continuation of the nerves of the valve. The panicle is also 



less divided, more spear-shaped, and the calyx is acuminated. Whole plant of a fine deep 



green colour, by which it is distinguished at first sight from every other species of Beat- 

 grass. 



Native of Britain. Root fibrous, perennial,
