This is one of the noblest of Chinese trees and is common in the warmer parts 

 of the Yangtsze Valley. It grows to a large size and has a wide-spreading head of 

 massive branches, a smooth, gray bark and bright green leaves. The colloquial 

 name is " Hon-erh-tsao " but in Chinese books it is usually referred to as the 

 " Wu-liuan-tzu." The saponaceous fruit is used as soap and the seeds are made 

 into rosaries and beads. The pale yellowish white wood is used for making combs 

 and for other purposes. Pictures of this tree will be found under Nos. 72, 403, 

 596, 0165 and 0232 of the collection of Wilson's photographs and also in his Vege- 

 tation of Wester?i China, Nos. 465 and 466.
