 linear or broader lobes : heads globular- or somewhat racemiform-capitate, both involucre 

 and flowers dark purplish-brown, the latter glabrous. Cham, in Bess. 1. c. ; DC. 1. c. A. 

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

 Arctic Alaska and islands. St. Paul's Island, Mrs. Alacintyre. (Adj. Asia.) 



T-r -H- Heads many-flowered, broad (2 to 5 lines in diameter), several or rather numerous and 

 loosely racemose or paniculate on mostly simple stems of a foot or less in height: subarctic and 

 subalpine, with dissected leaves and no cottony tomentum. 



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

 steins from a cespitose caudex : leaves silvery-canescent with fine very clo.se-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); cauliue sparse, mostly trifid : heads comparatively 

 small (2 lines high), several or rather numerous in a strict and simple racemiform inflores- 

 cence, fuscous : corollas pilose or sometimes glabrous. Suppl. 64, & DC. 1. c. 117 ; Torr. & 

 Gray, Fl. ii. 422. A. arctira & A. caspitosa, Bess, iu Hook. Fl. i. 323, 324. Arctic coast to 

 Bear Lake (Richardson, &c.), northern Rocky Mountains, and Mount Ranier, Washington 

 Terr., Tolmie. (From the char, probably A. heterophijl/a, Bess. Abrot., which is said to be 

 A. trifiircata, Steph. in Spreng. Syst. iii. 488, and to occur in Arct. Amer. as well as Arct. 

 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-uately 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 loug-peduncled : bracts of the involucre broadly brown- 

 margined : corollas yellow or turning brown, loosely pilose, rarely almost glabrous. Fries

 Bess, in Hook. Fl. 1. c. (mainly), & Abrot. 77, t. 4, of which the largest and coarsest-leaved 

 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 short-peduncled heads : leaves 2-3-pinuately parted into 

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

 long, oblong, not contracted at summit; the coat utricular. Abrot. 79, t. 5; DC. 1. c. A. 

 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 coast. Singularly, it grows wild in large tufts on 

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