Sir J. E. Smith has justly remarked in English Botany, that 

 this species approaches very near to S. decipiens (palmata, Sm.) ; 

 still, however, I think with him that it is specifically distinct. It 

 differs from decipiens in its less robust habit, acute segments of 

 its leaves, and acute laciniae of its calyx, its smaller flowers, and 

 obovate petals. My friend Mr. J. T. Mackay first discovered 

 this species on the Irish mountains. It has also been observed by 

 the late Mr. G. Don of Forfar, on rocks in the Western High- 

 lands. The Scottish specimens in Mr. Don's Herbarium agree 

 exactly with Irish ones from Mr. Mackay, and with the admi- 

 rable figure in English Botany.
