FAGACEAE. — QUERCUS 231 
Wilson (No. 7384; tree 15 m. tall, bark deeply furrowed); Ishikari province, 
Sapporo, September 20, K. Miyabe; Oshima province, Hakodate, woods, August 
1903, U. Faurie (No. 5421). 
This is the common Oak of northeast continental Asia. It is apparently common 
in Mandshuria, Korea and the Amur region and occurs sparingly in Saghalien and 
Hokkaido. In Japan it is abundantly represented by its variety grosseserrata, which 
is doubtfully distinct. We have much material before us, but unfortunately have 
little information of taxonomic importance. Wilson met with it as scrub only in 
Saghalien, but in the Hokkaido he notes that the very few trees he saw had dark 
and deeply furrowed bark. Whether this character is constant or not we do not 
know, and Wilson states that old trees of the var. grosseserrata are occasionally 
found with dark and furrowed bark. In herbaria the type may be recognized by 
the more thickened scales of the cup, which is usually slightly fringed, and by its 
broader and larger acorns. The dentation of the leaf is variable and the teeth are 
broad and rounded or narrow and acute. The quality of timber depends very 
much upon the habitat of the tree, but it is stated (W. S. in Timber Trades Journal, 
July 31, 1915) that “ that of Mandshurian Q. mongolica is indistinguishable from 
that of Q. grosseserrata." The wood of the continental Q. mongolica is not 
yet so well known commercially as the wood of the var. grosseserrata of Hok- 
kaido, but it would appear that the continental area is a timber field of much 
promise. It is vastly more extensive than that of Hokkaido, but we have no statis- 
ties giving the size and abundance of Q. mongolica. However, such information as 
we have points to its being a very common tree. 
We have not seen Mayr's Q. wutaishanica (Fremdl. Wald- & Parkbáume, 504, 
fig. 224 [1906]), but from his brief description and figure we strongly suspect that 
it is Q. mongolica Fischer with small leaves. : 
À picture of this Oak will be found under No. x425 of the collection of Wilson's 
Japanese photographs.
