sei-ved, far more frequent in the gardens of France, than in 

 our own, in which it flowers about September and Octo- 

 ber; in France a month or six weeks sooner. Drawn at the 

 Chelsea Botanic Garden. 



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 to. 

 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 Pei*soon 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. 



The genus is, we believe, wholly North American.
