84 FOSSIL FLORA OF THE JOHN DAY BASIN, OKEGON. [bull. 204. 



Of this species 1 have only seen the leaf figured. It is elliptical in 

 outline, very obtuse at apex, and rounded at ])ase. It is 8.25 cm. in 

 length to the petiole, which is less than 8 mm. long and 2 cm. in width. 

 The nervation consists of a very thick midrib and some four or five 

 pairs of alternate thin secondaries which arch and join some distance 

 from th(^ margin. 



This species has the nervation of living American species of Dios- 

 pyros, but is more obtuse at ap(>x than is usual in these leaves.

This species is represented in all the collections from Bridge Creek 

 by a large number of examples which agree exactly with Newberry's 

 tj'^pes. When the lower surface of the leaves is exposed the nervation 

 shows clearly, but when the upper surface is the one exposed it is 

 impossible to detect a trace of the nervation. This show^s conclusively 

 that the leaves were very thick and coriaceous. The upper surface is 

 also minutely wrinkled, as would l)e the case with a thick, leathery 

 leaf. From these considerations I am inclined to doubt the correct- 

 ness of referring' them to Fraxinus, but for the present they ma}^ be 

 so retained.
