Hab. Throug^hout 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 variahle, sometimes with short, narrow, very 

 woolly leaves, and extremely dense laciniae, (as found hy Mr. Menzies, Mr. Douglas, and Dr. Scouler, in 

 the North -West, and which I suspect may he the A. tomentosa of Pursh), at other times with the leaves 

 remarkahly elongated, the lower ones even a foot long, and three inches in diameter, cut into long- and 

 glabrous laciniae.
