This fine plant was first discovered by Mr. Nuttall, in 
the Arkansa country, where it is very abundant as far as the 
Red River: chiefly growing in prairies subject to occasional 
inundations, and flowering from June to October. In its 
native state, it is said to vary exceedingly in stature, being 
sometimes not a foot high, while in other situations it at- 
tains the height of five feet. 
Our drawing was made at Mr. Lee's Nursery, in last 
July. The species is now, however, to be found in many 
collections, having been introduced to this country at 
nearly the same time both from North America and Ger- 
many, where it was first published in Europe, by our friend 
Dr. Radius, in his Beschreibung neuer Pflanzen. 
We can find no where an explanation of the specific 
name of this plant. 
. The following is the character attributed by M. Cassini, 
in his latest publication, to this genus, which he observes is 
badly defined, and scarcely different from Dahlia.
