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. leporélla, 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.
