A native of a place called Mewries Island, in the river 

 Columbia, where it was found growing abundantly in the 

 year 1825. 



At first sight it resembles C. tinctoria so much as to 

 seem a slight variety only of that species ; but upon a more 

 exact examination, it proves very distinct in its perennial 

 root, and taller more branched stems, and less strongly 

 blotched flowers. In the early part of the summer, when 

 C. tinctoria is in perfection, this will attract but little 

 attention ; but when the charms of the former are past 

 away, Coreopsis Atkinsonia becomes, not indeed its rival, 

 but a yet more interesting beauty.
