Gaillardia pulchella, Foug. 

 Htmenopappus tenuifolius, Pursh. 



ACTINELLA ACAULIS, Nutt. 



Achillea Millefolium, Linn. 



Artemisia dracunculoides, Pursh. 



Artemisia Canadensis, Micbx. 



Artemisia cana, Pursh. 



Artemisia lddoviciana, Nutt. 



Artemisia biennis, Willd. 



Artemisia frigidda, Willd. 



Antennaria plantaginifolia. Hook. 



Senecio aureus, Linn., and vars. 



Senegio lobatus, Pers. 



Cirsium undulatum, Spreng. 



Cirsium Hookerianum, Torr. & Gray. var. Leaves mostly pinnately-parted, the segments 

 lanceolate or linear, sparingly spinulose-toothed. — L'Eau qui Court. (Flowers apparently 

 ochroleucous.) 



Cirsium Drummondi, Torr. & Gray. Only the heads, with their naked peduncles, were 

 gathered, so that the species is scarcely determinable. 



Ltgodesmia juncea, Don. 



Troximon cuspidatum, Nutt. 



Troximon glaucum, Nutt. 



Mulgedium pulchellum, Nutt. 



Lobelia spicata. Lam.

Campanula linifolia, Lam. 



Plantago major, Linn. 



Plantago Virginica, Linn. 



Plantago gnaphalioides, Nutt. 



Lysimachia ciliata, Linn. 



Aphyllon fasciculatum, Torr. & Gray. The name "P. glabra," of Pursh, is a little subse- 

 quent in date to Nuttall's P. erianthera; but the latter can hardly be said to be characterized 

 in Praser's catalogue, and the name is badly chosen, the an the' s being very slightly hairy, 

 that Pursh' s name may properly enough be preferred. This very handsome species has 

 recently been found by Hooker under the name of P. Gordonianus. This genus (Anoplon, 

 Waller, or Anoplavthus, Endlicher, but long ago called Aphyllon by Mitchell) will perhaps 

 be merged in Phelyp^a, Towrn.

Pentstemon gracilis, Nutt. 



Pentstemon albidus, Niitt. 



Veronica peregrina, Linn.
