136 Rydberg: Rocky Mountain flora 



This species has been taken for C. gracilis, or C. intermedia 

 gracilis, under which name it is more commonly known, but the 

 latter has much narrower leaves, the main portion not being wider 

 than the long lobes. C. intermedia, to which it is more closely 

 related, has much broader main portion of the leaves, and the lobes 

 are lanceolate and usually directed downward. C. angustata 

 grow on hillsides from Montana and Washington to Colorado and 

 Oregon. 



Colorado: North Park, 1896, Baker (type). 



Agoseris maculata sp. nov. 



Leaves oblanceolate, more or less pubescent, especially on the 

 margins and veins ; scape 1-2 dm. high, often sparingly hairy and 

 villous under the head ; involucre campanulate, about 2 cm. 

 high : outer bracts ovate or ovate-lanceolate, more or less villous 

 especially on the margins, dotted with blackish dots ; inner bracts 

 lanceolate ; ligules yellow or the outer tinged with reddish ; 

 achenes with a short striate beak. 



This is somewhat related to A. villosa, but differs in the broad 

 acuminate outer bracts. It grows in the mountains of Colorado 

 at an altitude of 3000-3900 m. 



Colorado : Silver Plume, 1895, Shear 4605 (type) ; Tennessee 

 Pass, 1902, Ostcrhout 264.3. 



Agoseris attenuata sp. nov. 



Leaves narrowly oblanceolate, 1— 1.5 dm. long, glabrous and 

 glaucous, usually denticulate, tapering into a short petiole ; scape 

 about 1.5 dm. high, villous near the head ; involucre campanulate, 

 about 2 cm. high ; outer bracts lanceolate, somewhat villous on 

 the margins, purplish on the back ; inner bracts linear-lanceolate 

 long-attenuate, equaling the pappus ; achenes light-brown, with 

 thick ribs, contracted above into a short striate beak. 



This is related to A. pumila and A. glauca, but differs from the 

 former in the smaller heads and narrower leaves, from the latter in 

 the more or less villous involucre, and from both in the elongated 

 inner bracts. It grows at an altitude of nearly 3000 m. 



Colorado: Mountain west of North Park, 1900, Ostcrhout 



2248. 



Agoseris roseata sp. nov. 



Leaves about 2 dm. long, long-petioled ; blades oblanceolate, 

 acute, denticulate or entire, glabrous and glaucous ; scape 5-6 dm.
