HAB. in montibus centralibus, leg. U. Mom, Dec. 1909. 



The species was first named as Quercus Miyabei by the late T. 

 KAWAKAMI, but the name was not published, as it was then considered to 

 be identical with Quercus spinosa DAVID. In examining again the species 

 and in comparing it closely with Q. spinosa, I have found that there are some 

 difference between the two. The leaves of the present Quercus are usually 

 elliptical or very slightly obovate-elliptical, while those of Q. spinosa are 

 always obovate. Moreover, the leaves of the former are nearly plain on the 

 upper surface, while those of the latter are very much impressed on the 

 costas and lateral veins. For this reason, it would be better to regard the 

 Forrnosan species as a variety of Q. spinosa.
