Dicentra Cucullaria (L.) Bernh. 



in moist woods in De Kalb and Lagrange Counties where it formed a 

 dense stand over acres. In the other counties where I found it only a 

 few plants were found at a place. I predict that where this species 

 becomes established in woodland, it will be the principal part of the 

 spring flora. This plant was formerly used in medicine but is no longer 

 official. This use is, no doubt, responsible for its cultivation and escape.
