This species ranges from New Brunswick to Florida and 

 Alabama, west to Ontario, Minnesota and Texas. The 

 habitat is wet soil on banks of streams, the time of bloom- 

 ing being from July until the close of September. In 

 Iowa the species frequently occurs and is generally dis- 

 tributed. Linnaeus gave the type locality as: "Habitat in 

 Virginite aquosis."

 from Chickasaw and Emmet counties. Professor Hitch- 

 cock reported the species from Story county; Professor
