RYDBERG: Rocky MouNTAIN FLORA ~ 649 
This has been taken for C. Aispida, but the original Diplopappus 
fuspidus Hook. is less hairy with longer hairs and more viscid ; the 
leaves are narrowly oblanceolate and petioled and the heads larger, 
the disk being 12-15 mm. wide. C. horrida grows on dry hills 
and plains at an altitude of 1200-1600 m.

vChrysopsis alpicola sp. nov. 
Cespitose perennial; stems about 1 dm. high, silky-villous, 
numerous; leaves oblanceolate, about 3 cm. long; nearly all 
petioled, white-silky strigose or the pubescence more spreading on 
the petioles ; heads solitary, subsessile, about 1 cm. high; bracts 
linear-lanceolate, hirsute, acute; disk about 12 mm. in diameter; 
fays about 8 mm. long and 2 mm. wide; achenes white silky- 
hirsute. 
This is perhaps most closely related to C. Bakeri, but is much 
lower, more silky, with sessile heads and more hirsute involucre. 
It grows on the higher mountains, at an altitude of about 3500 m.

v Solidago rubra sp. nov. 
Stout, about 3 dm. high ; stem pubescent or at the base merely 
puberulent, reddish; basal and lower cauline leaves broadly oblance- 
olate, 6-12 cm. Jong, firm, bluish-green, glabrous, pinnately veined, 
Serrulate and minutely scabrous on the margins, acute, petioled ; 
upper stem-leaves sessile and lanceolate ; inflorescence paniculate 
but very narrow and elongated ; heads about 8 mm. high. and as 
_ broad; bracts narrowly linear-lanceolate, acute, ciliolate on the 
Margin ; rays rather pale yellow, about 4 mm. long and 0.7 mm. 
wide ; achenes strigose. 
This species is related to S. scopulorum, but is distinguished by 
the stouter habit, the broad leaves, the compound and dense in- 
 florescence.
