6 Dentaria lacinialu. 



cate blossom-reel, inclining to white ; indeed, plants are frequently 

 found with entirely white flowers. In the vicinity of this city Dentaria 

 laciniata grows abundantly along the high banks of the Schuylkill 

 above the falls, in company with the species called Pepper-root, and 

 on the high banks of the Wissahickon creek. 



From the trials I have made with these two species, it appears to 

 me, they do not bear transplanting into a garden soil — at least they 

 require much care, and an artificial imitation of their native mould, to 

 ensure their growth and vigour. They do not increase in size or im- 

 prove in colour by any attention in their culture to which I have sub- 

 jected them.
