Gaillardia pulchella, Foug. 
Hymenopappus tenuifolius, Pursh. 
Actinella acaulis, Nutt. 
Achillea Millefolium, Linn. 
Artemisia dracunculoides, Pursh. 
Artemisia Canadensis, Michx. 
Artemisia cana, Pursh. 
Artemisia ludoyiciana, Nutt. 
Artemisia biennis, Willd. 
Artemisia frigidda, Willd. 
Antennaria plantaginifolia, Hook. 
Senecio aureus, Linn., and vars. 
Senecio 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. 
Lygodesmia juncea, Don. 
Troximon cuspidatum, Nutt. 
Troximon glaucum, Nutt. 
Mulgedium pulchellum, Nutt. 
Lobelia spicata, Lam. 
Specularia perfoliata, DC. 
Campanula rotundifolia, Linn. 
Campanula linifolia, Lam. 
Plantago major, Linn. 
Plantago Yirginica, 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 Fraser’s catalogue, and the name is badly chosen, the anthe’s being very slightly hairy, 
that Pursh’s name may properly enough be preferred. This very handsome species has 
recently been found by Hooker unde? 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^ea, Towrn.

Pentstemon glaber, Pursh. 
Pentstemon gracilis, Nutt. 
Pentstemon albidus, Nutt. 
Veronica peregrina, Linn.
