Trapa? microphylla Lx.

This is undoubtedly the same species as that figured by Lesquereux 

 from Point of Rocks, Wyoming, and by Ward from Burns Ranch, on the 

 lower Yellowstone. It shows more the habit of the specimen figured by 

 Ward, but has the general nervation of all the specimens referred to this 

 species. 



In fig. 15rt of Tertiary Flora the leaflets are petioled, while in fig. 15 

 they are clearly similar to Professor Ward's examples. 



These curious but well-marked leaves can not possibly belong to the 

 genus Trapa as we now understand it, but as I am at present absolutely 

 unable to suggest any other afiinity, I can do nothing- but leave their 

 correct determination to be settled b}' future workers. 



Habitat: North of Piny on Peak, on Wolverine Creek; collected b}- 

 Ai-nold Hague, August 10, 1887.
