and prolonged as a narrow wing on each side of the petiole ; apex long acuminate, 

 rounded at the tip ; margin entire, revolute ; lateral nerves about eight pairs, incon- 

 spicuous, dividing and looping before reaching the margin ; upper surface shining, 

 dark green, glabrous; lower surface pale, with deciduous minute appressed 

 pubescence, and showing under the lens shining dots ; petiole I in., with scattered 

 minute pubescence. 



Fruit (section Pasania) ripening in the second year, six to ten alternate and 

 sessile on an erect peduncle ; cupule ovoid, acute, f in. long, composed of several

This species is a native of Japan, Formosa, Korea, and central and southern 

 China. According to Sargent,^ it is the most widely distributed evergreen oak of 

 Japan, often forming extensive forests in southern Hondo. Its acorns are edible 

 when cooked and are sold in the Japanese markets. The most valuable mushroom of 

 Japan is artificially cultivated upon pieces of the bark of this tree.^ 



Siebold^ sent acorns of this and other Japanese oaks to Leyden in 1830 ; but it 

 appears to have been first introduced into England in 1879 by Maries.' The only 

 specimens which we have seen, those at Coombe Wood and at Kew, are shrubby in 

 habit. Maries also sent home from Japan a variegated form (van variegata),^ which 

 does not seem to be now in cultivation. (A. H.)
