Three very nearly related, but distinct species, seem to 

 have been confounded under Coreopsis rep tans. First, the 

 Linnean plant with simple ovate loner, and termite upper 

 leaves, deeply serrate, with oblong teeth, and a flower 

 having an indented ray : second, that of Sloane's work 

 (Hist. 1. 261) repeatedly, but erroneously adduced for its 

 synonym ; but in which none of the leaves are ovate simple 

 and deeply serrate, but uniformly termite and shallow lv 

 serrate, with short triangular teeth: third, our present 

 incisa, where the leaves are all either quinate or ternate, 

 deeply cut, and the ray of the flower pointed and quite en-
