Ehrhart), are slightly glaucous on the under side and are irregularly, often coarsely 
toothed, and the base is usually abruptly and broadly cuneate; the petioles and 
peduncles vary somewhat in length, but are relatively long. 
A picture of this tree will be found under No. 514 of the collection of Wilson's 
photographs.

This Beech is common on the higher mountains of northwestern Hupeh and east- 
ern Szech'uan, where it often forms pure woods. It is much more rare in southwest- 
ern Hupeh, and Wilson did not meet with it in western Szech’uan. It is a tree of 
moderate height and almost invariably the trunk divides at the very base into 
many stems which diverge somewhat from one another and never attain any great 
thickness. In the Japanese F. japonica Maximowicz the trunk divides in a similar 
manner, but into fewer stems, which grow to a greater size. In both species the 
ves are sinuous on the margins, dark green above and somewhat glaucous on 
the'under side, where the venation is prominently netted. The fruits are totally 
different, but these two species are undoubtedly closely related.
