In western Hupeh and in Szech'uan this is a very common Oak in mixed woods 

 on the mountains from near river-level up to 2000 m. altitude. In Japan it is rare, 

 and Wilson met with it there in only one locality. It is a tree from 20 to 25 m. 

 tall, with massive widespreading branches, and the bark is gray and fissured. The 

 leaves vary much in size and the petioles in length, but the under side of the leaves 

 is always more or less densely clothed with a matted felt of short pale gray hairs; 

 the shoots are always glabrous at maturity except occasionally immediately below 

 the clustered terminal winter-buds, where often a sparse puberulous indumentum 

 can be detected. In Hupeh this Oak is knovvTi as the Hu-li. Pictures of this tree 

 will be found under Nos. 501, 507 of the collection of Wilson's photographs and 

 also in his Vegetation of Western China, Nos. 428, 429.
