560 WILSON EXPEDITION TO CHINA 



Western Hupeh: Changyang Hsien, alt. 1200-1800 m. (Veitch Exped. No. 1456 

 and Seed No. 1196; bush 1 m., flowers green); without precise locahty, A. Henry 

 (No. 6503''). 



This species is nearest to A. leucorrhizus Harms, but is well distinguished by the 

 bristly leaves, by the inflorescence which consists of several short-stalked umbels, 

 and by the stout recurved prickles gradually tapering from a broad decurrent base 

 into a pungent point, while in A. leucorrhizus the prickles are slender and thin, 

 transversely compressed, and abruptly enlarged into a rather small and flat subor- 

 bicular base.
