the counties, particularly those of the more southerly pro- 

 vinces. Indeed, the j)retended species are so utterly un- 

 distinguishable by the book-characters, — copied from 

 author to author, without regard to the realities of nature, 

 and making no true contrast, one against another, — that 

 I cannot even separate the specimens in my own herba- 

 rium iuto two species according to book-characters. Not 

 that there are no obvious differences between the extreme 

 forms, but because there are so many intermediate forms, 

 to operate as connecting links, and render any decided 

 line of separation difficult or impossible.

Native. Littoral and Sub-littoral. The figure [5] re- 

 ferring to the province of Severn, in the line of area, is 

 enclosed because I find no recorded station on the coast 

 of that province ; so that the figure would have rested 

 solely on the authority of one locality quite inland, which 

 is reported in the Flora of Shropshire, — " Whixhall Moss ; 

 Mr. F. Dickinson." Likely to occur on the coasts of 

 Monmouth and Lincoln, that is, in provinces 5 and 8.
