A small handsome tree; introduced from China about 
1818 by Messrs. Barr and Brookes, of Balls Pond, New- 
ington. It flowers freely in the conservatory, and is said 
to produce two crops of fruit within the year. 
* As a species (we quote from Mr. Lindley) it stands 
* very distinct, having little more than generic affinity with
