lished, it may appear that I am assuming too many mis- 

 takes on the part of other botanists. This may turn out to 

 be the case in respect of some of the provinces ; and yet 

 the probability appears so strong that CEnanthe Lache- 

 nalii and Silaus pratensis have been mistaken for the present 

 species, in most or all of those which are excluded from 

 the area, that it seemed better to reject than to accept 

 them until verified, I have, however, allowed the province 

 of Trent to remain uninclosed, on the unconfirmed au- 

 thority of Sir Joseph Banks. That of the Peninsula stands 

 on good authority (namely, the Rev. J. C. Collins) ; and it 

 would have been accepted, but for the circumstance of 

 CEnanthe Lachenalii having only become clearly under- 

 stood by Biitish botanists several years later than the date 

 of Mr. Collins's record of the Peucedanum, in Burtle Turf 

 Moor, Somerset. Which of the two plants grows there ?

Alien ? Much difference of opinion has been expressed 

 by botanists, in respect to the civil claims of this species. 

 Hooker marks it introduced ; Babington places it among 

 those possibly introduced, though now apparently native ; 

 while Henslow allows it to pass unquestioned, as a native. 

 The majority appeal's against receiving it for a true Briton. 

 Perhaps, it might fairly be admitted to the category of 

 ' denizens,' for the provinces of Hvunber and the Lakes ; 

 less confidently so, in those of the Tj-ne and West Low- 

 lands.
