The general appearance of this plant indicates the inferior com- 

 parative value manifested in the above details. It appears, accord- 

 ing 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 exposed 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 figure and 

 disposition of the florets aud panicle it seems to connect the A.ver- 

 ticillata, A. stolonifera, var. angustifolia , and A. alba, in a series. 



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

 about the end of the same month.

* Since this sheet was sent to the press, Mr. Taunton informs me, the Agrostis 

 lobata grows wild on a stiff wet clayey loam, part of the London blue clay, in the 

 parish of Cuddington, near Epsom, Surrey.
