178 WILSON EXPEDITION TO CHINA 



but occasionally specimens from 20-25 m. tall are met with. The bark is gray, 

 fissured and rather rough and the tree contains little or no poisonous sap. The 

 branches are moderately thick and form an oval or rounded head. Colloquially 

 this Sumach is known as the " Ching-fu-yang," while the galls which are often 

 produced on the leaf are called " Ch'i-pei-tzu " and are used as a medicine. A 

 picture of this tree will be found under No. 346 of the collection of Wilson's 

 photographs and also in his Vegetation of Western China, No. 448. 



The Sumach in cultivation as R. sinica is this species. On young plants the 

 leaflets are deeply toothed but on adult trees they are quite entire.
