It comes very near to HELENIUM mexicanum of the 
“Nova genera et Species Plantarum;” insomuch that we 
should have been inclined to deem it of the same species 
but for the different conclusion of M. Kunth has come the 
Among other distinctions he mentions the florets of the 
disk as smooth in mexicanum, which is clearly not the case 
in our plant. The point is however, we suspect, to be de- 
termined by future observation. 
The florets of the ray are here generally trifid, as in 
mexicanum. In autumnale they are frequently 5- and 6-cleft, 
In fact no available difference can be established on this 
character, which is extremely variable in the genus. We 
think however that the curious cuneate form of the florets 
of the ray might have entered with advantage into the ge_ 
neric character. ; ; 
The florets of the disk are 4-cleft throughout in this 
species, not 5-cleft as usual in the order. The whole flower 
when bruised has a strongly aromatic flavour. 
Messrs. Pursh and Persoon have erroneously stated the 
species to be perennial; and the former is evidently mis_ 
taken in speaking of it as growing from three to five feet 
high. Don MSS. Ay 
The genus is, we believe, wholly North American.
