MIOCENE FLORA— BAD LANDS. 235 



what similar to this is seen on the leaves of Acer sderophyllum, Heer, 

 "FI. Tert. Helv.," iii, p. 55, pi. cxvii, figs. 6-9, where fig. 8, without basilar 

 lobes, has the secondary nerves parallel, as in the leaf of fig. 6, I. c, while 

 fig. 9 is distinctly three-nerved at base and three-lobed. Seen upon the 

 specimens these two leaves have, indeed, a similar facies by their color, 

 the subcoriaceous texture, the polished surface, &c.

SAPINDACE^. 



SAPINDUS, Linn. 

 " U. S. Geol. Rep.," vU, p. 263. 



Sapinclus obtiisifolius, Leeqx. 



Plate XLVIII, Figs. 5-7. 

 Ibid., p. 266, pi. xlix, figs. 8-11. 



The leaflets are slightly more acute than those figured in volume vii, 

 but less acuminate and broader than those of Sapindus affinis, Newby., 

 "Later Ext. Fl.," p. 51, "lUustr.," pi. xxiv, fig. 1. As the specimens from 

 Florissant have the leaflets still more obtuse, the differences may represent 

 mere local varieties of the same species.

Juglans uigella, Heer. 

 Plate XLViA, Fig. 11. 

 Heer, "Fl. Foss. Alask.," p. 38, pi. ix, figa. 2-4. 



Leaves pinnate; pinnules large, ovate-lanceolate, unequilateral at base, gradually 

 narrowed to the apex, acutely serrate; lateral nerves close, mucli curved, reticulate 

 along the borders; nervilles at right angles, distant, flexuous, nearly simple and par- 

 allel. 



The fragment of a leaflet figured is evidently referable to this species,
