This species is very variable in breadth of leaves, stalking of leaflets, length of 
pedicels, and size of fruit, but these variable characters do not work together or with 
geographical distribution in suggesting possible segregates, 
Smyrnium nudicaule Pursh has been identified by Messrs. Robinson and Greenman 
(Proc. Philad. Acad. 28. 1898), who examined the type in the herbarium of the 
Philadelphia Academy, to be the same as Sese/i leiocarpuim Hook., which accords far 
better with the rather puzzling type locality of the former when the name was 
applied to plants of the eastern plains.
