The specimen is in flower and presents immature leaves, which are 

 glabrous and considerably smaller than are those on our Chinese material. 

 The tree is manifestly deciduous, the new leaves appearing with the flowers 

 I can see no reason, in the absence of more complete material, and especially 

 mature leaves and fruits, for distinguishing this Philippine form from this 

 well-known Chinese and Japanese species. In floral characters it conforms 

 very closely with material from southern China.
