clearly the same as A. Lindleyanus, To it. and Gray, which name 

 may be continued, although A. ciliolatus, Lindley, is aj^parenlly only 

 a small form of it. 



A. sPECTABiLis. The well-marked species, cultivated at Kew 

 Gardens in 1777. 



A. RADULA. The recognized species, originally from Nova Scotia, 

 near Halifax. 



A. BLANDUS, Pursh, FI. ii. 555, is a species of Solander's, in the 

 Banksiau herbarium, described and published by Pursh from too 

 scanty material, a specimen collected on Bisque Island in the St. 

 Lawrence by Halbgren. And Solander indicates as a variety of 

 this a specimen from John Bartram. If not reduced and nearly 

 smooth forms of A. puniceus, both must belong to the A. tardi'Jiorus, 

 L., which see. 



v. Species originating in Michaux, Flora Boreali- Americana, 1803. 



A. SOLIDAGINEUS. The Sericocnrpus soUdagineus of Nees. 



A. Marilandicus. Sericocarpus conyzoides^ Nees. 



A. TORTiFOLius. Sericocarpus tortifoUus, Nees. 



A. INFIRMUS. Somewhat earlier published than A. cornifolius, 

 Muhl. in Willd. Spec, for the volume containing the latter cites 

 Michaux. The habitat, " a Canada ad Carolinam," is erroneous as 

 respects Canada : the stations assigned in Michaux's Flora are not 

 rarely incorrect in a similar way« As is well known, this is A, 

 divaricatus of Linnseus as regards the synonymy, but not of his her- 

 barium, nor of the specific character. The present name is to be 

 adopted. 



A. ACUMiNATus. The well-known species. It appears, from the 

 herbarium of Jussieu, that this is the A. divaricatus of Lamarck, but 

 not of Linnteus. 



A. UNiFLORUS. A small and simple-stemmed form of the A. 

 nemoralis of Aiton. 



A. SUBULATUS. A mixture of the small-rayed and conyzoid coast 

 species and of the nearly-related larger-rayed one (^A. divaricatus, 

 Torr. and Gray, Fl.), but in the proper herbarium mainly the former, 

 to which only the character applies, especially the "ligulis radii 

 minutis." This name to be employed, for it proves that no part of A. 

 linifolius, L., belongs here. 



A. ARGENTKUS. A. sericeus, Vent., slightly earlier published.
