On the mountains of western Hupeh and in eastern Szech'uan between altitudes 

 of from 800 to 1600 m. this is a very common tree in mixed woods and often forms 

 pure stands; in western Szech'uan it is much less common. In Japan it is sometimes 

 cultivated, but Sargent and Wilson did not see it there as a wild tree. At its best 

 it is a tree 25 m. tall with a straight trunk 3 m. in girth and clothed with hand- 

 some pale gray deeply furrowed corky bark. The fruit ripens the second season, 

 and is usually solitary', but occasionally in pairs. The shoots are quite glabrous, 

 slightly pubescent or tomentose, but the under side of the leaves is always clothed 

 with a dense pale gray felt. On young plants — seedlings or coppice growth — 

 the petioles are very short and the leaves may be described as subsessile; the base 

 is rounded or subauriculate and the secondary veins are more numerous. The 

 cup and the acorn are variable in size. In central and western China this tree is 

 known as the Hwa-k'o-li and its wood is valued for boat building and general con- 

 struction purposes; the cups are employed in dyeing silk-yam black; the bark is 

 used by the peasants for roofing their houses. On the trunks of felled saplings of 

 this Oak an edible fungus (Hirneola polytricha) is cultivated by the Chinese in 

 western Hupeh. 



Pictures of this tree will be found under Nos. 537, 544, 555, 0142 of the collec- 

 tion of Wilson's photographs and also in his Vegetation of Western China, Nos. 441, 

 442, 443. 



We have not seen Hance's Q. Mould, but beUeve that it belongs here. The 

 vernacular name given, Ma-lieh, is doubtless a transliteration of Hwa-li, the Chinese 

 name for Q. serrata Thunberg, and often appUed also to Q. variabilis Blume.
