B. betulina (Lodd. Bot. Cab., t. 404, copied in Stephenson and 

 Churchill, t. 121, and Woodville. Bentley and Trimen Med.

 less esteenjed than those of the other two species here named and 

 are of less commercial value. 



The leaves of B. hetulina are shorter than the other species, and 

 from this circumstance are known in commerce as short BifcMi, or
