662 GEOLOGY OF THE YELLOWSTONE NATIONAL PARK. 



DiosPYRos STENOSEPALA Heer. 



Diospyros stenosepala Beer. Lesquereux : Fifth Ann. Eept. U. S. Geol. and Geogr. 

 Surv. TeiT., p. 296, 1871 (1872). 



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

 shore of Yellowstone Lake." 



Fraxixus denticulata Heer. 



PL LXXVIir, fig. (I. 1 



Fraxinus denticulata Heer: FL Foss. Arct., Vol. L p. 118, PI. XVLfig.4; Pi. XLVII, 

 fig. 2. Lesquereux : Tert. Fl.. p. 228. PI. XL. fig.s. 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 ))elong 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. Kuowlton, July 27, ISSS. 



Viburnum rotundifolium Ix. 



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



Tihtrnum rotundifolhim Lx.: Tert. FL, p. 22.5, PL XXXVII. tig. 12; PL XXXVIII, 

 tig. 10; PLLXI, 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., PI. LXI, fig. 22), while fig. 8 

 is like fig. 10, PI. XXXVni (loc. cit.). 



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

 Arnold Hague, August 10, 1887.
