160 JOURNAL OF THE ARNOLD ARBORETUM (vol. iv 



The specimens from the Tien tan shan and from Yung ning have the 

 petioles less pubescent than the type or even glabrous but the pubescence 

 of the under side of the leaves and their obovate shape is the same, though 

 they are larger, measuring up to 15 cm. in length and to 11.5 cm. in width. 

 This variety has not yet been found outside of Honan.

This variety differs from the type in the glabrous or nearly glabrous 

 under side of the leaves. I do not see how Schottky 's var. pekingensis 

 can be distinguished from Blume's variety by the description given by the 

 authors; I have seen no specimen of Q. aliena from the neighborhood of 

 Peking except Q. aliena f. calvescens but none with "foliis . . . glaber- 



rimis."
