 and rooting and the upper portion erect; leaves opposite,

This species ranges from Nova Scotia to British Colum- 

 bia, south to eastern Virginia, Alabama, Nebraska, and New 

 Mexico. Also said to be a native of Asia and Europe. 

 Linnaeus gave the type locality as: "Hab. in Europa ad 

 fossas." In Iowa the species occurs in springs, pools, and 

 brooks, and is rather frequent in eastern Iowa and extends 

 westward across the state. Our specimens were collected 

 during June and July, but the species blooms as early as 

 May and as late as September. 



Specimens in our collection are from Winneshiek, Alla- 

 makee, and Appanoose counties. The State University 

 herbarium has specimens from Louisa, Johnson, Winne- 

 bago, Emmet, and Lyon counties. Prof. Bessey reported 

 the species from Story county and Prof. Fink from Fay- 

 ette county.
