t Centaurea intybacea, Willd. 



Area [15]. 



Incognit. In the fields by the shore in several places, 

 in Forfarshire, according to Mr. George Don ; who adds an 

 opinion, that it must have been confounded with C. Scabi- 

 osa, which it very much resembles. (Stat. Ace. Forf.) It 

 seems likely that Don may have given the above name to 

 the pale-flowered variety of C. Scabiosa, mentioned in 

 Gardiner's Flora of Forfarshire ; the resemblance between 

 the two species not being such as to render their confusion 

 very probable. 



614. Centaurea Isnardi, Linn. 



Samian. Found in the Isle of Guernsey, and said to 

 differ very little (Bab. Man. ed. 2) fi-om C. aspera; to 

 which latter, indeed. Dr. J. D. Hooker referred the Guern- 

 sey plant in a letter received from him, in October, 1846.
