Damp places, New England to Dakota, Nebraska and Texas, 
south to the Gulf of Mexico, across the southern boundary of the 
United States and on the Pacific coast; also in Cuba, and said to

Llysanthes gratioloides has a more extensive geographic distri- 
bution than any other of our species. It ranges over the whole 
United States, except a part of the Rocky Mountain region, al- 
though further exploration may show its existence there. It is 
Said to be native in South America and eastern Asia and to be 
naturalized in western Europe. I have not seen foreign speci- 
mens.
