—This is certainly very distinct from the Europaean A. Ptarmica, not only in foliage, but remarkably so
in its dense compound corymbs, and the extremely short ray of the flowers.

Hab. Throughout the British. Possessions, from Lake Huron to the Arctic Sea, and from the Atlantic
to the Pacific Ocean.—On the North-West coast this plant is most variable, sometimes with short,narrow, very
woolly leaves, and extremely dense lacunae, (as found by Mr. Menzies, Mr. Douglas, and Dr. Scouler, in
the North-West, and which I suspect may be the A. tomentosa of Pursh), at other times with the leaves
remarkably elongated, the lower ones even a foot long, and three inches in diameter, cut into long and
glabrous laciniae.
