About this well-marked species, of which, however, we 

 find no figure, there can be no doubt. It is very common 

 in the northern parts of North America. We have speci- 

 mens out of Michaux's Herbarium, which we owe to the 

 kindness of Mons. Achille Richard ; and also from Lake 

 Michigan and New York from Dr. Torrey. Its corymbose 

 white flowers, with a reflexed ray, at all times distinguish it. 



A hardy handsome perennial, in the Gardens 5 or 6 feet 

 high, but much smaller when wild ; flowering in September, 

 and readily propagated by division of its roots.
