Mr. W. Wilson is surely right in referring this plant to the 

 genus Potentilla. It was natural for Linnaeus and the botanists 

 who followed his system, to separate it, on account of the fewer 

 stamens and pistils ; but as the number of these is not constant, 

 there can be no doubt it is merely a Potentilla with the number 

 of these organs diminished.
