FAGACEAE. — QUERCUS 231 



Wilson (No. 73S4; 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 Saghaiien 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 

 Saghaiien, 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 ty])e 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- 

 tics 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. wulaishanica {Fremdl. Wold- & Parkbdume, 504, 

 fig. 224 [1906]), but from his brief description and figure we strongly suspect that 

 it is Q. moiigolica Fischer with small leaves. 



A picture of this Oak will be found under No. x425 of the collection of Wilson's 

 Japanese photographs.
