This species occnrs in swamps, from Labrador to British 

 Columbia, south to southern New York, Michigan, Minne- 

 sota, and California. It is also found in Europe and Asia. 

 Messrs. Barnes, Reppert, and Miller in their Flora of Scott 

 and Muscatine counties state that this species occurs in 

 low wet ground at Noels, Scott county. This is the first 

 and only report of its occurrence in the state and extends 

 the range considerably southward. Type locality: "Habi- 

 tat in Europse inundatis."

This species ranges from Nova Scotia to British Colum- 

 bia, south to Florida, Alabama, Mexico, and California, 

 generally speaking from the arctic circle to the gulf of 

 Mexico; also in Central and South America, and distrib- 

 uted as a weed in the old world. Linna3us gave the type 

 locality as: "Hab. in Europe hortis, arvisque." In Iowa 

 the species is common in most places in woods by water 

 courses or in cultivated soil where it grows as a weed. The 

 flowers open all summer, from May until the close of Sep- 

 tember. 



Specimens in our collection are from Johnson, Decatur, 

 and Shelby counties. We have observed the species in 

 Winneshiek county. The State University herbarium has 

 specimens from Henry, Lee, and Dallas counties. Prof. 

 Hitchcock reported the species from Story county; Prof. 

 Fink from Fayette county; Messrs. Nagel and liaupt and
