ICOSANDRIA— POLYGYNIA. Potentilla. 421 



In reply to a question of this gentleman, in his 3Ius. v. 1 , 73, I must 

 observe that his P. Halleri, so admirably delineated in Haller's 

 Hist. t. 21. f. 4, is the original authority for P. aurea, taken up 

 by Linnasus without seeing a specimen, as his manuscript shows. 

 In Sp. PI. ed. 1, he had referred Haller's plant to verna. He 

 long afterwards received from Seguier our present P. alpestris, 

 which he marked aurea, and this might well mislead me. This 

 specimen however he has no where described in his works. 

 Some others of the same species he confounded, like Haller, 

 with verna. I trust this manifold error will now be set at rest 

 by the establishment of P. alpestris. Nestler has altogether 

 misled Prof. Hooker respecting this and P. opaca.
