Hab. Canada. (iVcc5.) Lake Huron. Dr* Todd, — This is N^ees' A. vimineus: but Dr, Boott considers 

 it as probably a variety of A. puniceus, 



23. A. laxifolius ; foliis anguste lanceolatis utrinque attenuatis mucronato-serrulatis 

 flaccidis supra scabris, caule scabro racemoso-composito angusto, ramis apice racemosis vel 

 subcompositis, involucri foliolis linearibus squarrosis floris primarii sub^qualibus. Nees, Ast.

Hab. Woody country from lat 54° to 64°. Dr, Richardson, Rocky Mountains, in swampy places, to 

 Hudson's Bay. Drummond. Near Quebec. Mrs, PercivaL — /3. Rocky Mountains. Drummond, Slave Lake. 

 Dr, Richardson. — This is a very distinct and well marked species. The more northern specimens have the 

 narrowest leaves. T possess the same plant from Philadelphia, sent to me by Dr. Griffith.

Hab. Rocky Mountains. Drummond. — A. hrumali affinis ; foliis capitulisque multo majoribus, caule 

 simplici subcorymboso ramisque rigidis pilosis fere apbyllis nee virgatis glabris foliosis, bene distinguitur ? 

 Lindl.

 acutis. Nees, Ast. p. 83, — A. Novi Belgii. Nutt. (fide Nees.) — /3. caule magis composito 

 magisque piloso-lineato. — A. luxurians, Spreng, Syst. Veget. v. 3. p. 538. 



Hab. ,6, Canada. Mrs, PercivaL — This, which Professor Lindley, and, I doubt not, correctly, refers to 

 A. luxurians /3. of NeeSy Dr. Boott considers A, tardiflorus, Nees, (not Linn.) while another, equally quoted 



» 



by Dr. Lindley under A, luxurians, /3. Dr. Boott calls A. Novi Belgii, S. minor. The three are perhaps not 

 really different. — Nearly allied to this is a specimen of an Aster from Dr. Scouler, gathered on the Columbia, 

 which Professor Lindley inclines to refer to A, asper.
