OF ARTS AND SCIENCES. 173 



A. ELEGANS. Described from a cultivated plant of unknown origin; 

 the specimen in the herbarium is A. spectahilis, Ait., under which 

 De Candolle cites the species, but also under A. squarrulosus. 



A. CONYZOIDES. Sericocarpus conyzoides, Nees. 



A. VERSICOLOR. Name to be adopted for the species most closely 

 related to A. Icevis, L. It is represented in the herbarium by fol. 1, 2, 

 and perhaps 3, which has no flowers. Fol. 4 is of A. Carolinianus, 

 and fol. 0, of some other species, possibly A. salignus. 



A. LiEViGATUS. A mixture in the herbarium. Fol. 1 is either 

 A. Icevis or A. versicolor ; fol. 2 is a fragment of A. prenanthoides, 

 Muhl. ; fol. 3, of A. puniceus ; fol. 4 is wholly doubtful ; and fol. 5 is 

 of -4. Iceviffaius, Lam., a far older homonym. 



A. PRENANTHOiDES, Muhl. The wcll-markcd species, from Muhl- 

 enberg. 



A. AMPLEXiCATJLis, Muhl. Kot the homonym of Lamarck, nor of 

 Michaux. This is A. Icevis, L. 



A. RECURVATUS, Willd. The specimen, '• Hort, Berol.," seems to 

 be A. paniculatus, Lam., or near it; but something else would appear 

 to be described, perhaps A. diffusus, Ait., surely not A. thyrsiflorus, 

 Hoffm., to which De Candolle refers it in part, for the corolla is 

 said to be no larger than in A. Tradescanli. 



A. FLORiDajNDUS. Plant of the gardens, apparently A. Novi- 

 Belgii. 



A. SEROTINUS. Apparently either A. Icevigatus, Lam., or a form 

 of A. Novi-Belgii. 



A. LANOEOLATUS- Seemingly the A. paniculatus, Lam. 



A. DRAcrxcuLOiDES. Cultivated specimens : fol. 1, 2, are of A. 

 paniculatus, Lam. ; fol. 3 of same with smaller heads, verging to the 

 Morisonian A. Tradescanti. 



A. FRAGiLis. The Morisonian A. Tradescanti, not the A. Trades- 

 canti, \ar. fragilis, Torr. and Gray. 



A few notes are added upon the representatives of some earlier 

 species in the Willdenovian herbarium. 



A. NEMORALis. Two sheets ; not Alton's plant, but a Galatella of 

 the Old World; and to this the character evidently belongs, being 

 the same as the 



A. HYSSOPIFOLIUS. The "Am. Bor." is a continuation of an origi- 

 nal mistake. Same of A. lixifolius. 



A. SOLIDAGINOIDES. Michaux's A. solidagifieus, with a Greek 

 instead of the oriijinal Latin termination.
