 radical and lower leaves oblong-linear or narrowly spatulate, glabrous, 

 entire, with ciliate-scabrous margins, the cauline linear-lanceolate, 

 partly clasping; scales of the hemispherical involucre numerous, closely 

 imbricated, unequal, nearly glabrous, the exterior linear-oblong, obtuse, 

 the innermost acute; achenia minutely hairy. Median. Canon City, 

 Brandegee. Twin Lakes, Coulter. 



Var. CILIATIFOLIUS, T. & G. Low; stem not denuded and scapiform,

Yar. PARRYI, Watson. Stem l-2 high, often corymbosely much 

 branched; leaves large, broadly oblanceolate, 5 / -12 / long, l'-2' wide, nar- 

 rowed into winged petioles, the upper ones gradually smaller and ses- 

 sile, partly clasping; heads large; in volucral scales finely ciliate, the 

 outer ones broadly lanceolate with herbaceous tips, scarious below, 

 loose; peduncles not glandular. Sierra Madre Range, Coulter.

ASTER ERICOIDES, L., var. STRICTUS, Porter. Low, f-l high, gla- 

 brous, except the scabrous margins and ciliate bases of the leaves, erect* 

 slender, paniculately branched above, branches short; scales of the in- 

 volucre narrowly linear, lax, outer ones very acute, often entirely green, 

 inner ones scarious with a central green line; radical leaves narrowly 

 oblanceolate. "In the mountains at middle elevations," Hall & Har- 

 bour, 254. Near Denver, Coulter. Foot-hills west of Denver, Porter ;

ASTER MULTIFLORUS, Ait. Near Denver, Dr. Smith. North Park,

ASTER FALCATUS, Lindl. Stem minutely pubescent with appressed 

 hairs, 1-1 high, leafy to the top ; leaves rigid, minutely appressed- 

 pubescent or smoothish except on the edges, the lower ones spatulate- 

 lanceolate, obtuse or acute ; 2 / -3 / long, 4 // -6" wide, short-stalked, the 

 upper ones oblong-linear, sessile, often slightly clasping, those of the 

 erect branches linear, often slightly falcate; heads terminal on the
