Jeffersonia diphylla (LJ Pers. 



County in the herbaria of Wabash College and Indiana University. The 

 specimens are all from low ground in woods in the counties bordering the 

 Ohio River. The type specimens were collected at Lemon's Gap, North 

 Carolina, which is located at an elevation of about 3,500 feet about 13i/o 

 miles west of Hot Springs, North Carolina. 



The leaflets of all of my specimens are very thin, not revolute, and more 

 or less pubescent beneath. The short and blunt anthers on very broad 

 filaments are very distinctive. Broad filaments alone, however, can not 

 be used to differentiate this species because other species also have wide 

 filaments. The achenes are usually few, mostly stipitate, and reflexed 

 when mature. This is a tall plant of wet woods.

 quent to common throughout the state in moist woods. It often spreads 

 and persists after woodlands are cleared because of its creeping root- 

 stocks and the fact that no grazing animal will eat it. The rhizomes are 

 cathartic and have long been much used in medicine. The mature fruit
