affinity of this species is with Z. Bungd Planchon, and Z. setosum Hemsley, from 

 both of which it is easily distinguished by its undulate leaves.

In extreme forms this variety looks very distinct from the type, yet in the spines, 

 in the shape of the leaflets and in the width of the wings on the petioles we cannot 

 find any constant character by which to distinguish it specifically from the Indian 

 plant. The only difference appears to be in the number of the leaflets which is 

 from 3 to 5 in the variety and 5 and more in the type. In the specimen from 

 Yunnan, however, this character too is not constant. 



This shrub is abundant throughout the warmer parts of central and western 

 China, more especially in rocky places and by the side of streams. A colloquial 

 name for it is " Kou-hua-chiao."
