CiRSiUM HOOKERIANUM, ToiT. & Gray, var. Leaves mostly jjinnately-parted, the segments 

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

 ochroleucous.) 



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

 gathered, so that the species is scarcely determinable.

Plantago major, Linn. 



Plantago Yirginica, Linn. 



Plantago gnaphalioides, Nutt. 



Lysimachia ciliata, Linn. 



Aphyllon fasciculatum, Torr. & Gray. The name "P. ghhra," 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 under the name of P. Gordonianus. This genus (Anoplon, 

 "Waller, or Anoplanthus, Endlichcr, but long ago called Aphyllon by Mitchell) will perhaps 

 be merged in Phelyp.ea, Tourn.
