spatulate or oblanceolate, 3-12 lines long, mostly acute: heads numerous, 
3-4 lines high, cylindraceous, or the staminate campanulate, in terminal 
spicately or cymosely disposed glomerules: involucre very woolly at base; 
of the pistillate heads commonly 4 lines long, of the staminate shorter, the 
inner in both with conspicuous rose-purple or ivory- white tips which in 
the latter are obtuse, in the former narrower and acute. In dry open 
woods, eastern Washington to California, not common. 
* * Not surculose-stoloniferous : stems simple from the subterranean 
branching caudex, rather strict, leafy, naked at the summit, and 
bearing a mostly cymose-compound cluster of heads: inner bracts of 
, the staminate involucre all with conspicuous ivory-white obtuse tips; 
those of the pistillate hwit hardly any tips: herbage silvery-lanate: 
larger lower leaves 3-nerved.

8-12 inches high : leaves all narrowly linear or some of the lowest narrowly 
lanceolate-spatulate, small, uppermost linear-subulate: heads small (2 
lines or the pistillate barely 3 lines long), several or numerous: inyolucre 
glabrous nearly or quite to the base; its inner bracts in the pistillate heads 
obtuse: achenes glandular; the spatulate and asit were petaloid tips of the 
staminate pappus obtuse.”’ Brit. Columbia to Oregon and Wyoming, east 
of the Cascade mountains. 
A. argentea Benth. Pl. Hartw. 319. Silvery lanate with a very fine 
and seomewhat strigose pubescence: stems slender, 10-20 inches high, 
leafy, leaves linear-lanceolate or broader to linear, 1- 4 inches long, atten- 
uate below to a margined petiole with a dilated and somewhat clasping 
base, more or less prominently 3-nerved: heads small numerous, panicl-

leaves spatulate-lanceolate, 1-3 inches long, attenuate below toa slender 
petiole, the upper linear, with conspicuous scarious tips: heads several to 
many, in a close capitate terminal cluster: involucre 2-3 lines high, dense- 
ly woolly at base, the inner bracts with conspicuous white tips; of the sta- 
minate flowers broad and obtuse, of the pistillate linear and acute: achenes 
glabrous: pappus of the staminate flower: of moderately dilated bristles. 
On high mountains, Brit. Columbia to eastern Oregon. 
* * * Surculose-proliferous by either subterranean or humifuse and 
leafy shoots or stolons. 
+ Involucre woolly at base. 
A. media Greene |. c. 286. A. alpina ofauthors as to the American

densely silky-woolly : flowering stems 1-6inches high: radical leaves broad- 
ly spatulate to obovate, 4-10 lines long; cauline linear-spatulate to linear: 
heads few to several; the pistillate sessile in a close capitate cluster, with 
brown narrow lanceolate acute involucral bracts; the staminate heads oft- 
en somewhat panicled, with oblong mostly obtuse bracts with scarious 
white tips: pappus but little if at all thickened upward. On the highest 
mountains, Brit. Columbia to California and the Rocky Mountains.

silvery-canescent and floccose: stems stoutish, 2-12 inches high, leafy:- 
leaves of the sterile shoots oblanceolate to spatulate, an inch or more 
_ long; of the flowering stems linear-lanceolate to linear, 1-1% inches long: 
heads usually numerous, in a close panicle: bracts of the involucre rose-
