A. microcephala, GRAY. Simple-stemmed, slender, silvery -woolly : lower leaves spatu- 

 late ; uppermost small and linear : heads rather numerous, small, loosely paniculate : invo- 

 lucre nearly glabrous throughout, fuscous, of the narrow female heads 3 lines long, of the 

 broader male heads 2 lines long, the somewhat colored (whitish or purplish) tips scariuus 

 and inconspicuous: bristles of the male pappus with much dilated tips. Proc. Am. Acad.

 Stretch, Lemmon, ice. 



* # Not surculose-stoloniferous: stems simple from the subterranean branching caudex, rather 

 strict, leafy, naked at summit, and bearing a mostly compound-cymose cluster of broad heads: 

 inner bracts of the male involucre all with conspicuous ivory-white papery obtuse tips: those 

 of the female with hardly any tips and more scarious : herbage silvery-lanate : larger lowi-r 

 leaves 3-nerved. 



A. luzuloides, TORR. & GRAY. Closely silky-woolly : stems slender, a span to a foot high : 

 leaves all narrowly linear, or some of the lowest narrowly lanceolate-spatulate, small upper- 

 most linear-subulate : heads small (2 lines, or the female barely 3 lines long), several or 

 numerous : involucre glabrous nearly or quite to the base ; the inner bracts in the female 

 heads obtuse : akenes glandular : the spatulate and as it were petaloid tips of the male pap- 

 pus obtuse. Fl. ii. 430 ; Gray, Bot. Calif. 1. c., excl. var. Oregon, Washington Terr., and 

 borders of Brit. Columbia, east to Wyoming. 



A. argentea, BENTII. Larger, 8 to 16 inches high: lower leaves all spatulate (the larger 

 4 or 5 lines wide) : heads numerous in a more compound cyme, broader (fully 3 lines long) : 

 involucre in both sexes whiter than in the preceding species ; innermost bracts of the female 

 acutish : tips of male pappus even more dilated. PI. Hartw. 319. A. lu~u]oid>-s, var. argen- 

 tea, Gray in Pacif. II. Rep. iv. 54, & Bot. Calif. 1. c. California, in the Sierra Nevada, from

A. Carpatllica, R. BR. Floccosely white-woolly, rather stout : lower leaves spatulate- 

 lanceolate and the upper linear : heads broad, 3 or 4 lines long : involucre conspicuously 

 woolly at base, more or less livid, except the white tips to the bracts of the male; the inner 

 bracts of the female commonly acutish and thin-scarious : akenes smooth and glabrous. 

 The typical plant 2 to 6 inches high, with a simple close cluster of 3 to 7 heads, or even a 

 solitary head: bristles of the male pappus gradually and moderately enlarged upward.

Var. pulcherrima, HOOK. 1. c. Stems 6 to 18 inches high : leaves mostly larger, the 

 radical often half-inch or even almost an inch wide : heads more numerous, often in a com- 

 pound cyme : bristles of the male pappus with more strongly and abruptly or even scariously 

 dilated tips ! Rocky Mountains at lower elevations, extending to New Mexico, Oregon, 

 and Brit. Columbia ; first coll. by Drummond. Passes into the typical form as to stature, and 

 even as to pappus.

 first species least so.

A. alpina, G^DRTN. Somewhat cespitose : radical shoots few and short : flowering stems 1

 head: radical leaves spatulate, half-inch long: involucre 3 lines high, livid-brownish; the
