36 THE FLORA OF THE DAKOTA GROUP. 



Ill my Cret. Fl. (loo. cit.) 1 have described and figured as. referable to 

 this species an isolated cone with its scales and seeds. Prof. Heer has con- 

 tradicted this reference, thei-efore the fragment of a branchlet figured here 

 is the first evidence observed in the Dakota Group of a species which 

 has been found widely represented in the Lower and Middle Cretaceous 

 of Greenland and of Europe. The identity of this fragment is sufficiently 

 shown by the character of the leaves and then- scars upon the branches, 

 especially resembUng Figs. 8, 8a, PI. xx, and Fig. la, PI. xxxiv of Heer's
