I am quite unable to decide as to the validity of the segregates 

 which have been formed from this species. There appear to be many 

 distinct forms, and some, at least, like stolonifera, can apparently be 

 always separated from the others without difficulty. Much further 

 study — histological and experimental, as well as morphological— 

 is necessary before a satisfactory account can be rendered of this 

 aggregate. Mr. Riddelsdell gives localities for six varieties. 

 »757' vulgaris, With. ( = tenuis, Sibth.). Common Bent Grass. Meus- 

 wellt addfain. 

 Common. Abundant. Native. Pascual, ericetal. 



Occasionally, as in parts of Gower, it forms the bulk of the 

 vegetation in poor pastures.

 Mr. Chapman, who says that his specimens did not occur on the 

 ballast. Penarth and Cardiff ; on the ballast. J.S. The proximity 

 of thes3 localities to the docks, and the absence of recent records, 

 suggest that it was introduced with ballast, obtained a temporary 

 foothold, but failed to establish itself.
