multinervia (nervis ramosissimis) calyce subsequa- 

 lia. 



This species of potentilla was first discovered in 

 Britain by the late Mr G. Don of Forfar, who 

 found it on the Braes of Balquhidder, and other 

 hills in Perthshire, in considerable plenty. 



This species has often been confounded with P. 

 verna, although the habits of the plants are widely 

 different. Potentilla verna is three times smaller, 

 always spreading flat on the ground ; the stems are 

 very short and thick ; the petals are much shorter ; 

 the leaves are quinate, the leaflets obovate, slightly 

 serrated, shining on the upper surface, never rugose ; 

 the stem-leaves all alternate, never opposite; stipules 

 ovate, smooth, obtuse ; segments of the calyx short- 

 er ; petals smaller and paler ; the whole plant is 

 slightly clothed with very fine adpressed hairs. 

 The figure given of it in English Botany, is ex- 

 tremely good and accurate. Willdenow is wrong in 

 quoting Hudson for a synonym of P. opaca, Hud- 

 son's plant being nothing else than P. verna.
