334 ' COMPOSITE. [Senecio, 



Chamisso, gathered in the Bay of St. Lawrence, on the Asiatic side of Behring's Straits, and with the figures 

 in Keichenbach above quoted, others are much larger, of a firmer texture, more leafy on the stem, bearing a 

 greater number of flowers, and approaching some of the dwarf states of the preceding species.

 rare, Drummond, and thence to Fort Franklin, on the Mackenzie River. — The bracteas are less remarkable 

 in the specimens of the second Expedition, than in the solitary individual gathered on the first. May it not 

 be the -S*. Canadensis of Linnjeus ?

Lessing quotes under this the Arnica maritima of Linnsens and Pursh, the authority for which is the " Aster 

 s. potins Helenium maritimum, &c. of Gmelin,Fl. Sibir. v. 2. p. 175" : but that is described as hearing many 

 branches, and numerous flowers, and I think cannot in any way correspond with our plant, of which all 

 the specimens that I bave seen have a simple stem and a solitary flower. May this not be the Senecio 

 Doronicum of Pursh ?
