39. BHAMNACE.E. 120 



Under the name B. dahuricus, Lawson (in Hook. f. Fl. Brit. 

 Ind. i. p. 639) unites B. globosus, Bunge, B. virgatus, Bx)xb., and 

 several other forms, which certainly differ from each other as 

 much, or even more, than some of the species retained. On the 

 other hand, it is difficult to define satisfactorily the limits of the 

 eastern Asiatic species of Bhamnus. See note under Bhamnus 

 tinctorius.

The Indian and the Hongkong plants are different from this 

 northern species, which is more nearly related to B. globosus, 

 Bunge, and B. argutus, Maxim.
