In habit and period of flowering it corresponds exactly with 

 S. alpina, already figured at fol. 1460 of this work: in our Gardens 

 it differs chiefly in its flowers being pale yellow, without any stain of 

 violet, and in the flower-heads having a less disposition to elongate, 

 so that the bractese have pretty constantly that compact arrangement 

 to which the name hop-headed owes its origin ; the leaves are also 

 generally larger, more obtuse, and perhaps less sessile. The character 

 in the inflorescence just alluded to, appears, however, to be lost in a 

 wild state, as is evident from Gmelin's plate, which Besser has rightly 

 referred to this species. We therefore cannot but adopt Mr. Bentham's 

 opinion, that Sc. lupulina is a mere variety of S. alpina, into which 

 it may be traced even from its best-defined state. 



To the kindness of this gentleman we owe not only the corrected 

 generic and specific characters given above, but also the following 

 valuable enumeration of all the species comprehended in the genus.
