scribes as Fagus deueaUonis. They differ by the coriaceous texture, the 

 secondaries more or less curved iu traversing - the blade, rigid, forming 

 narrow rectangles; the borders entire, even in the upper part, and the 

 acuminate apex longer and narrower than in PI. iv, fig. 3, Xachtrage 

 zura foss. fl. of Greenland Fl. Arct., v. The affinity is so marked that I 

 do not separate these leaves iuto a new species, but the differences are, 

 however, evident. The rectangles formed by the nervilles are recog- 

 nized even in numerous small fragments of these leaves.

From Contra Costa County, Cal. Collected by Mr. H. W. Turner. 

 Age, probably Pliocene. 



Diospyros virginiana L., var. Turneri, n. var. 



The leaves have the same form and size as those of I), virginiana 

 Linn., and appear to represent the same species, differing merely by the 

 lowest pair of secondaries at a more acute angle of divergence than those 

 above. In D. virginiana the same character is also sometimes observ- 

 able, but rarely indeed, and the difference in the direction of the lower 

 secondaries is much less marked. There is no species of Diospyros in 

 the present flora of California. A number of species, however, are 

 now in the flora of Japan. These fossil leaves described here have also 

 a degree of affinity to I), lotus, var. japonica (D. Japonica S. et Z.), but 

 the basilar secondaries of the last species are parallel to those above it.
