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 18 
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-yarn 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 m 
western Hupeh. 
Pictures of this tree will be found under Nos. 537, 544, 555, 0142 of the collec- 
= of Wilson’s photographs and also in his Vegetation of Western China, Nos. 441, 
, 443. 
We have not seen Hance's Q. Moulei, but believe 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 applied also to Q. variabilis Blume.
