said to grow in Somerset, Worcestershire arid Sliropshire ; 

 and though these counties cannot be considered very un- 

 likely, they rest only on rather doubtfiil authority. The 

 county of York was published for it in the New Guide, 

 through an inadvertence ; Orobus sylvaticus having been 

 marked in a printed list, accidentally, instead of Orobus tu- 

 berosus. The same locality in that county, however, has 

 been since re-stated on a second authority ; but I do not 

 include the locality of " Richmond " within the area of this 

 species, until it ajDpeavs that the second announcement is 

 something better than a plagiarism of the former error. I 

 am at a loss how to indicate the range of altitude, and con- 

 sequently that of temperature also. Most of the stations 

 probably lie between 50 and 200 yards ; and whether any 

 of them are below or above this range of elevation, I am 

 quite unprepared to say with certainty. There is uncer- 

 tainty, again, in giving the usual situation of the species ; 

 for it seems to be as much a pascual or sylvestral plant as 

 a rupestral one.
