NEW OR NOTEWORTHY SPECIES. 163 
spatulate-ovate to lanceolate, 2 to 8 inches long including 
the petiole, acute, remotely serrate though often obscurely 
$0; cauline leaves few, reduced, lanceolate and sessile: hemi- 
spherical involucres 3 inch high and rather broader, usually 
12 or more in the corymb; bracts of involucre very narrow, 
equal, acuminate, sparsely hispidulous: rays extremely nar- 
row and numerous, rather more than 4 inch long, white, 
changing to deep pink; pappus simple, its slender bristles 
only about 16 or 18; achenes sparsely strigulose under a 
strong lens. 
Species, strikingly analogous to E. Philadelphicus in habit 
and inflorescence. Detected by the author in moist mead- 
ows of the Gunnison River, Colorado, 1 Sept., 1896. 
ERIGERON ELATIOR E grandiflorus, var. elatior, Gray. 
Stems somewhat clustered, stout, erect, 2 feet high, leafy up 
to the monocephalous, or usually distinctly corymbose sum- 
mit, hirsute-pubescent, the foliage scabrous: leaves ovate- 
lanceolate, acute, entire: heads 1 to 8, on bracted peduncles ; 
Involucres very large, often more than 4 inch high and $ 
luch broad, its linear attenuate-acuminate bracts squarrose- 
spreading, embedded in dense soft wool: raysshowy, numer- 
ous and narrow: achenes pubescent; pappus of rather firm 
bristles and a conspicuous outer cirele of white squamelle. 
Mountains of Colorado, at from 8,000 to 9,000 feet. Species 
hot at all related to E. grandiflorus, nor even analogous to 1t 
except in the woolliness of the involuere; more truly allied 
to E. macranthus, 
EnrGERON CERVINUS. Stems slender, 8 to 12 inches high 
tom stout ascending rootstocks, leafy at base, the whole 
herbage glabrous, only the peduncles and involucres gland- 
ular and slightly puberulent: leaves all very thin, entire, | 
the lowest with obovate blade less than an inch long, and 
slender petiole of 2 inches or more; the few and remote cau-
