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

Hab. On the gravelly banks of Cedar Lake, lat. 54°. Dr. Richardson. Woods of the Saskatchewan,
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 Linnæus ?

Lessing quotes under this the Arnica maritima of Linnæus and Pursh, the authority for which is the “ Aster
s. potius Helenium maritimum, &c. of Gmelin,Fl. Sibir. v. 2. p. 175” : but that is described as bearing many
branches, and numerous flowers, and I think cannot in any way correspond with our plant, of which all
the specimens that I have seen have a simple stem and a solitary flower. May this not be the Senecio
Doronicum of Pursh ?

—/3. Chiefly in the Arctic regions. Dr. Richardson. Capt. Sir E. Parry, fyc.—I am quite unable to distinguish
S. congestus as a species from S. palustris; Mr. Drummond’s and Dr. Richardson’s specimens show
intermediate gradations.

Hab. About Fort Vancouver, on the Columbia. Douglas, and Nicholas Garry, Esq.—I am unable to
refer to any established genus this plant, which, however, I think will rank with the Senecionidece. As in
Senecio aureus, the axills of the leaves bear a tuft of woolly hair; but in the present plant this is far more
copious and conspicuous; so much so, as to have suggested the generic name, *£«*»», a lock o f wool.
