fifth one, reduced to a purple scale on the roof of the corolla tube ; 

 calyx five-cleft, with rounded lobes. Capsule ovoid, thin, papery, 

 two-celled, opening at the top. Seeds many, small, rough, dull 

 brown. (Fig. 265.) 



S. leporella, Bicknell, is a closely related plant, differing in 

 having more coarsely toothed leaves, and flowers with corolla 

 more contracted at the throat, the sterile stamen greenish yellow ; 

 it is even more frequent on hillsides and brushy pasture. Range 

 from Connecticut to Minnesota, southward to Nebraska and 

 North Carolina. 



Means of control 



The roots may be killed by persistent 

 cutting, aided by salt or carbolic acid 

 on the cut surfaces. Or they may be 

 grubbed out or pulled when the ground 

 is soft, and perhaps sold for enough to 

 pay for the trouble of their extraction.

it as hay, when it is injurious to the Beard-tongue 

 flavor of dairy products.
