PI. LXXVIII, fig. 1. 

 Dombeyopsis platanoides Lx. : Tert. Fl., p. 254, PI. XLVII, figs. 1, 2, 187S. 



A single specimen. 



Habitat: Top of Mount Everts, west face; collected by George M. 

 Wright, July 7, 1885. 



Andromeda grayana Heer. 



Andromeda grayana Heer: Fl. Foss. Alaska, p. 34, PI. VIII, fig. 5. Lesquereux: 

 Tert. Fl., p. 234, PI. XL, fig. 4. Knowlton: Bull. U. S. Geol. Surv. No. 105, 

 p. 56. 



Habitat: Mount Everts, near the summit of the west end; collected 

 by F. H. Knowlton, July 27, 1888. 



Trapa! microphylla Lx. 



PI. LXXVII, figs. 3, 4. 



Trapa? microphylla Lx.: Tert. Fl., p. 295, PI. LXI, figs. 16-17«. Ward: Types Lara- 

 mie Fl., p. 64, PI. XXVIII, figs. 2-5. 



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. 15« 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 affinity, I can do nothing but leave their 

 correct determination to be settled by future workers. 



Habitat: North of Pinyon Peak, on Wolverine Creek; collected by 

 Arnold Hague, August 10, 1887.
