Description: The base and apex of the leaf are not perfect. The 

 leaf is about 10 cm. long and 5 cm. wide. It has seven or eight pairs 

 of secondaries with a smaller, fainter, secondary near the basal 

 border. In outline and venation the leaf resembles those described 

 and figured by Lesquereux and Newberry, op. cit. The specimen is 

 of the Sternberg Collection, from the U. S. National Museum, and 

 bore a label referring it to Diospyros roHindifolia. The resemblance 

 to Diospyros rotundifolia is much less than to Diospyros priniccva and 

 I, therefore, have referred it to the latter species.
