The Pepper-root grows fpontaneoufly in Canada, in the 

 Penfylvanian mountains, in the extenfive forefts of TenafTee, 

 and in the loftieft mountains of Carolina. The inhabitants of 

 thefe countries dry the root and ufe it as a condiment with their 

 food, inftead of multard or pepper, whence its Anglo-American 

 name. 



As our plant produced only one cauline leaf, and the flowers 

 pofTefTed very little inclination to a yellow colour, we at firit 

 hefitated to pronounce it to be the fame with Michaux's. But 

 upon fhewing our drawing to Mr. Frederick Pursh, he 

 immediately recognized it for Dentaria diphylla or Pepper- 

 root, and from him we learn, that the number of leaves on 

 the item is indeterminate, ftrong plants frequently throwing out 

 two, nearly oppofite, and fometimes a third below. This 

 gentleman has devoted feveral years to the ftudy of North- 

 American botany, and we hope ere long to fee from his pen a 

 more extenfive Flora of thofe regions than we have hitherto 

 po defied. 



A hardy perennial ; propagated by dividing its roots ; com-
