Hab. North -West America. Dr. Scouler.—Oi this. Dr. Scouler gathered two specimens, one above 

 aescribed with glabrous inrohicres ; the other with very downy ones. This latter I can scarcely distinguish 

 from what I take to he the true A. Lttdoviciana of Nuttall. 



8. A^Purshiana [Bess.); suffruticosa adscendens incana, calathidibus paniculatis ovatis, 

 panicula foliosa stricta, flosculis nudis, foliis subtus albidis, caulinis lanceolatis subcuncatis 

 mucronatis intcgerrimis. Bess. Monogr. Art. ined. cum ic.—a. latifolia; folia elliptico- 

 lanceolatis 1^ longis, i" latis.— (A. integrifolia. Rich, in Frankl. \st Journ. ed. 2. App.p. 

 30. fide Herb, nostr.)—!^. angustifolia ; foliis lanceolatis, l^' longis, 3'" latis. 



Hab. On the plains of the Saskatchawan. Vr. jRichardson. Drummond.—^, Red River. Douglas, in 

 Herb Lindl— (This is certainly the A. inteyrifolia of Dr. Richardson, and I presume also of Pursh ; but 

 probably it is not the Siberian plant figured by Gmel. Sib. v. 2. t. 48. The leaves are sometimes downy on 

 both sides, sometimes glabrous above, whence I feai- it comes too near the following species.— if.) 



9. A. Douglasiana (Bess.); suffruticosa (?) stricta canescens, calathidibus spicato-panicu- 

 latis bemisphcerjcis, panicula subfoliosa, flosculis nudis, periclinii squamis ellipticis, interioribus 

 apice scariosis, foliis subtus incanis, caulinis lanceolatis acutis intcgerrimis. Bess. Monogr. Art.

Ab A. integrifolia dififert foliis intcgerrimis, panicula magna, calathidibus minoribus glomerato-spicatis ; 

 ab A Purshiana vero caule stricto, foliis acumiuatis (non mucronatis,) panicula; mmis f^longatis, calathidibus 

 majoribus, periclinii squamis apice scariosis (nee incano-tomentosis,) colore totius plautT minus cano, foliisque

10. A. arctica [Bess.); c^spitosa, calathidibus racemoso-spicatis glomeralis globosis, 

 pedunculis apice lanatis, flosculis apice subpilosulis, periclinii squamis superne fuscis scariosis, 

 foliis subsericeis inferioribus pinnatisectis, superioribus trifidis, laciniis radicalium tri-quin-

Hab From Bear Lake to the shores of the Arctic Sea. Dr. Richardson.— (Two of the specimens in this 

 coUection have the whole pknt clothed with long silky hairs. ^.)-In my first account, I gave the name of 

 A borealis to this plant ; but have been convinced by Lessiug's work, that it is not the A. hormhs of Pallas. 

 Its appeUation is therefore changed as above, and I only regret not having altered it to Ilichardsoniana, as it 

 is to be feai-ed tbe present name cannot stand, Lessing having thus called a variety of A. Chamissoniuna.
