10 ' RANUNCULACE^. [Banmailu,. 



Hab. Cape Charles, Labrador. Captain Robinson, July, 1820.— The specimen gathered ia Labrador 



was given to me, with several other very interesting plants from that country, by the late Mr. Morrison. 



It is undoubtedly the same as the Europiean plant, but scarcely exceeding two inches in height. It is 



possible that the seeds may have been brought to Labrador by the Missionaries; but as I have no means of 



ascertaining this point, I think it safer to introduce the plant as a doubtful native of N. America, than to 

 omit it altogether,
