Native. Littoral, Glareal. There are yet two excep- 

 tions to the provincial generality of this species, so far as 

 the published reports and my private notes show its 

 distribution. I believe to have seen it at Allonby, on the 

 coast of Cumberland, wliich would fill in the vacancy for 

 the Lake province, if made certain. The other province, 

 that of Severn, has a very limited coast line, and one for 

 which we have yet very little botanical information pub- 

 lished ; namely, the county of Monmouth, with a small 

 portion of Gloucester. The No. for that pro\dnce [5] is 

 excluded in the line of area, as at present resting only on 

 the authority of Mr. Edwin Lees, who mentions the in- 

 land county of Worcester for this littoral gi'ass, in the 

 New Botanist's Guide, — perhaps through inadvertence ; 

 although, as some other littoral plants do occur in certain 

 saline spots in the valley of Severn, it is possible that the 

 Ammophila also may be one among them.
