560 WILSON EXPEDITION TO CHINA 



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

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

 (No. 6503*). 



This species is nearest to A, leucorrhizus Hanns, 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.
