The only typical specimens of Quercus aliena I have seen from northern 

 China are Hers' no. 1119 from Hon^n and Cowdry 's no. 1302 from Chili. 

 The other references cited above probably belong to the following varieties 

 or forms; those from Chili and from Shensi may be Q. aliena pellucida or 

 Q. aliena calvescens. From Kansu I have seen no specimens.
