 Hills, Washington Terr, to N. California ; first coll. by Geyer. 

 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 scarious 

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

 x. 74, & Bot. Calif. 1. c. — Dry eastern slope of the Sierra Nevada, in California and Nevada, 

 Stretch, Lemmon, &c. 



# # 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 lower 

 leaves 3-nerved. 



A. luzuloid.es, 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, Benth. 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. luzuhides, var. argen- 

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

 Siskiyou Co. to the Yosemite district. 



A. Carpathica, 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. —

 t. 951. Gnaphalium Carpathicum, Wahl. Fl. Carp. 258, t. 3. — Labrador (a monocephalous 

 form ! ) and Anticosti, and from the northern Rocky Mountains to mountains of Oregon and 

 Washington Terr. (Eu., N. Asia.) 



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. 



# # Surculose-proliferous by either subterranean or humifuse and leafy shoots or stolons, in the 

 first species least so. 



-i— Heads in a cymose cluster, sometimes solitary: involucre woolly at base. 

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

 to 4 inches high, bearing 2 to 5 heads, sometimes (var. monocephala, Torr. & Gray) a single 

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

 inner of the male heads with whitish oblong tips, of the female wholly livid and scarious 

 and from acutish to acuminate : akenes glandular. — Less, in Linn. vi. 221 ; Hook. 1. c. ;
