naturalized. This, then, is A. IVadescanti of Linnaeus, Spec. PI., as 

 to syn. Moris., which gave the name, and in part as to Hort. CliiF. 

 That is, of the two specimens in Cliffort's herbarium, one belongs to 

 Morison's species ; the other, which was taken up in Torr. and Gray's 

 Flora as the foundation of the species, is the racemose A. vimineus, 

 Lam., A. Tradescanti fragiUs, Torr. and Gray. But I now understand 

 that Cliffort's herbarium is really no authority for Linnajan species. 

 The specimen preserved in the Linna^an herbarium is from the Upsal 

 Garden, of unknown date; but as " Ilort. Ups. 262 " is cited under 

 the species, it was probably in hand when the character was drawn 

 up. It belongs to a related species with larger heads, of which the 

 next oldest name is A. paniculaius, Lam. This name should be em- 

 ployed for the larger-flowered, and A. Tradescanti for Tradescant's 

 small-flowered species. 



A. Novi-Belgii. This is really founded wholly on the A. Xovce- 

 Belgice latifoUus umbellatus Jloribus dilute violaceis, Herm. Hort. 

 Lugd. 67 and (tab.) 69, which, from early specimens, can be fairly 

 identified with a polymorphous species still common in the gardens, 

 in a variety of forms and under several names, A. Jloribundus, serotinus, 

 adulterinus, eminens, prcsaltus, &c., all of them apparently derived 

 from a common and most variable species of the Atlantic States near 

 the coast, which has been by me referred (not correctly) to A. longi- 

 folius, Lam. But the indigenous specimen so named in the Linnajan 

 herbarium, from Kalm, is clearly A. puniceus, L., and one from the 

 Upsal Garden is A. paniculaius. Lam., or near it. 



A. TARDIFLORUS, founded entirely on specimens cultivated in the 

 Upsal Gai'den, is confidently identified with a low form of A. patulus, 

 Lam., a northern species, not rare in cultivation, but little known by 

 indigenous specimens. This low form is most like A. prenanthoides. 

 The species dates only from the second edition of the Species Plan- 

 tarum ; it is said to have been cultivated for eighteen years before it 

 flowered, and then late in the season. But the cultivated Aster which 

 matches the Linna;an specimens (of two sterile stems with lower 

 leaves, and a stronger flowering one destitute of them) blossoms unu- 

 sually early. So it is doubtful whether the Linna^an name (which has 

 commonly been applied to a form of A. Xovi-Belgii) ought to be 

 kept up. 



A. GRANDIFLOEUS. Not in the Linna^an herbarium; but this well- 

 marked species is founded on the excellent figures of Martyn and
