 and flowers dark purplisli-brown, the latter glabrous. — Cham, iu Bess. 1. c. ; DC 1. c. A. 

 Senjavinensis, Ledeb. Fl. Koss. ii. 588, at least in part, not Bess. Perhaps an extreme arctic

 subalpine, with dissected leaves and no cottony tomentum. 



A. Richardsoniana, Bess. A span to near a foot high, with rather slender ascending 

 stems from a cespitose caudex : leaves silvery-canescent witli fine very close-pressed pubes- 

 cence ; radical twice ternately or quinately divided or parted into oblong-linear or narrower 

 lobes (of only 2 or 3 lines in length) ; cauliiie' sparse, mostly trifid : heads comparatively

 Asia to Kamtschatka.) 



A. Norvegica, Fries. Rather stout, 5 to 25 inches (commonly a foot) high, from villous 

 or sericeous-pubescent to glabrate : leaves twice 3-7-nately parted into linear or lanceolate or 

 more dilated segments: heads large (commonly 4 or 5 lines broad), loosely racemose or 

 racemose-paniculate, most of them long-peduncled : bracts of the involucre broadly brown- 

 margined : corollas j-ellow or turning brown, loosely pilose, rarelj^ almost glabrous. — Fries

 form is his var. Ochotensis ! — Arctic coast to the Aleutian Islands, &c., in various forms. 

 (Adj. E. Asia.) 



A. Parryi, Gray. Rather stout, a foot or less high, wholly glabrous, leafy up to the loosely 

 paniculate inflorescence of numerous shoi't-peduncled heads : leaves 2-3-pinnately parted into 

 mostly linear thickish lobes : involucre 2 or 3 lines broad, its bracts greenish with brownish 

 margins and with the corollas glabrous. — Proc. Am. Acad. vii. 361. — Mountains of Colo-

 Chinensis, Pursh, Fl. ii. 521, not L. &c. — This may be what Pursh saw in herb. Lambert, 

 from N. W. America, probably from Pallas. It is indigenous from Kamtschatka to Japan, 

 and not improbably on the American coa.st. Singularly, it grows wild iu large tufts on 

 Lynn Beach, Massachusetts ! Also of Sweden, Fl. Dau. t. 3045.
