222 GRASSES OF BRITAIN. 



PoA MARiTiMA (variety) hispida. 



Rough Sea Meadow- Grass. 



Plate XCIX. 



This variety is distinguished from Poa maritima^ figured in Plate 

 XLIL, in the stem being compressed, the rachis furrowed on one 

 side, and the branches rough with small tooth-like bristles. In other 

 respects the two plants are nearly similar. 



This grass was sent me by Mr Babington, who gathered it in 

 Suffolk, and who justly considers it to be the Sclerochloa maritima, 

 described by Fries.
