662 GEOLOGY OF TEIE YELLOWSTONE NATIONAL PARK. 



Diospyros stenosepala Heer. 



Biospyros stenosepala. Heer. Lesquereux : Fifth Ann. Rept. IT. S. Geol. and Geog. 

 Snrv. Terr., p. 296, 1871 (1872). 



Habitat: "Divide between the source of Snake River and the southern 

 shore of Yellowstone Lake." 



Fraxinus denticulata Heer. 



PI. LXXVIII, fig. 6. 



Fraxinus denticulata Heer: Fl. Foss. Arct., Vol. I, p. 118, PI. XVI, fig. 4; PL XLVII, 

 fig. 2. Lesquereux : Tert. Fl.. p. 228, PI. XL, figs. 1, 2. 



Several well-preserved specimens that are referred with certainty. 

 Besides these there are several other well-preserved examples, of which the 

 one figured is perhaps the best, that are somewhat larger than the types, 

 but still appear to belong with them. The nervation is obscure, but the 

 shape and toothed margin are quite similar. 



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

 F. H. Knowlton, July 27, 1888. 



Viburnum rotundifolium Ix. 



PI. LXXVII, fig. 10; PL LXXVIII, figs. 2, 8. 9. 



Viburnum rotundifolium Lx.: Tert, FL, p. 225, PL XXXVII. fig. 12; PL XXXVIII, 

 fig. 10; Pl.LXI, tig. 22. 



There is considerable difference in size among the specimens, but they 

 seem to belong together, and to approach quite closely to Lesquereux's 

 species. The small leaf shown in fig. 9, for instance, is certainly the same 

 as the plant figured by Lesquereux (loc. cit., PL LXI, fig. 22), while fig. 8 

 is like fig. 10, PL XXXVIII (loc, cit.). 



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

 Arnold Hague, August 10, 1887.
