A perennial plant, native of the swamps of North 
America, from Canada to Carolina, which it adorns with 
its fine rosy blossoms. It was one of the first species 
introduced from the New World ; and yet it is very rarely 
cultivated in this country, because it seldom or never 
flowers in the open border, where, being quite hardy, it 
is usually placed. This is, we believe, owing to the 
general lowness of our isothermal temperature. Mr. Col- 
vill, with whom it has now flowered, informs us, that 
* The {@:0x0¢ of Dioscorides was one of the South of Europe Malvaceous 
plants; but it is not certain which.
